<onlyinclude>'''Crystallisation''' is the formation of crystals from a solution. In a crystal, the atoms or molecules are highly organised into a solid repetitive structure. "A solution is a mixture of two or more species that form a homogenous single phase. Solutions are normally thought of in terms of liquids, however, solutions may include solids suspension. Typically, the term solution has come to mean a liquid solution consisting a solvent, which is a liquid, and a solute, which is a solid, at the conditions of interest. The solution to be ready for crystallization must be supersaturated."<ref>Sattar Al-Jibbouri "Effects of Additives in Solution Crystallization", 2002, https://sundoc.bibliothek.uni-halle.de/diss-online/02/03H046/prom.pdf</ref>

A simple example for crystallisation is the evaporation of the solvent. For example, the salinity of the Great Salt Lake in Utah, USA, is so high that through the evaporation of water salt crystals cover its shores. Some other ways in which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation.</onlyinclude>

=== Origin and composition ===
The feedstock for crystallisation is a solution with crystallisable ingredients, e.g. minerals or organic molecules. The majority of minerals and organic molecules crystallise easily, and the resulting crystals are generally of good quality, i.e. without visible defects. However, larger biochemical particles, like proteins, are often difficult to crystallise. The ease with which molecules will crystallise strongly depends on the intensity of either atomic forces (in the case of mineral substances), intermolecular forces (organic and biochemical substances) or intramolecular forces (biochemical substances).

=== Pre-treatment ===

==Process and technologies==
Crystallisation occurs in three major steps. The first is nucleation, the appearance of a crystalline phase from either a supercooled liquid or a supersaturated solvent. The second step is known as crystal growth, which is the increase in the size of particles and leads to a crystal state. An important feature of this step is that loose particles form layers at the crystal's surface and lodge themselves into open inconsistencies such as pores, cracks, etc.

Crystallisation is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering, crystallisation occurs in a crystalliser. Crystallisation is therefore related to precipitation, although the result is not amorphous or disordered, but a crystal.

Crystallisation and precipitation

[[File:2021 Great Salt Lake 06.jpg|alt=Picture showing a mound of salt crystals at the Great Salt Lake in Utah, USA|thumb|Salt crystals at Great Salt Lake, Utah, USA]]
<onlyinclude>'''Crystallisation''' is the formation of crystals from a solution. In a crystal, the atoms or molecules are highly organised into a solid repetitive structure. "A solution is a mixture of two or more species that form a homogenous single phase. Solutions are normally thought of in terms of liquids, however, solutions may include solids suspension. Typically, the term solution has come to mean a liquid solution consisting a solvent, which is a liquid, and a solute, which is a solid, at the conditions of interest. The solution to be ready for crystallization must be supersaturated."<ref>Sattar Al-Jibbouri "Effects of Additives in Solution Crystallization", 2002, https://sundoc.bibliothek.uni-halle.de/diss-online/02/03H046/prom.pdf</ref>

A simple example for crystallisation is the evaporation of the solvent. For example, the salinity of the Great Salt Lake in Utah, USA, is so high that through the evaporation of water salt crystals cover its shores. Some other ways in which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation.</onlyinclude>

=== Origin and composition ===
The feedstock for crystallisation is a solution with crystallisable ingredients, e.g. minerals or organic molecules. The majority of minerals and organic molecules crystallise easily, and the resulting crystals are generally of good quality, i.e. without visible defects. However, larger biochemical particles, like proteins, are often difficult to crystallise. The ease with which molecules will crystallise strongly depends on the intensity of either atomic forces (in the case of mineral substances), intermolecular forces (organic and biochemical substances) or intramolecular forces (biochemical substances).

=== Pre-treatment ===

==Process and technologies==
Crystallisation occurs in three major steps. The first is nucleation, the appearance of a crystalline phase from either a supercooled liquid or a supersaturated solvent. The second step is known as crystal growth, which is the increase in the size of particles and leads to a crystal state. An important feature of this step is that loose particles form layers at the crystal's surface and lodge themselves into open inconsistencies such as pores, cracks, etc.

Crystallisation is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering, crystallisation occurs in a crystalliser. Crystallisation is therefore related to precipitation, although the result is not amorphous or disordered, but a crystal.

Crystallisation and precipitation

[[File:2021 Great Salt Lake 06.jpg|alt=Picture showing a mound of salt crystals at the Great Salt Lake in Utah, USA|thumb|Salt crystals at Great Salt Lake, Utah, USA]]
<onlyinclude>'''Crystallisation''' is the formation of crystals from a solution. In a crystal, the atoms or molecules are highly organised into a solid repetitive structure. "A solution is a mixture of two or more species that form a homogenous single phase. Solutions are normally thought of in terms of liquids, however, solutions may include solids suspension. Typically, the term solution has come to mean a liquid solution consisting a solvent, which is a liquid, and a solute, which is a solid, at the conditions of interest. The solution to be ready for crystallization must be supersaturated."<ref>Sattar Al-Jibbouri "Effects of Additives in Solution Crystallization", 2002, https://sundoc.bibliothek.uni-halle.de/diss-online/02/03H046/prom.pdf</ref>

A simple example for crystallisation is the evaporation of the solvent. For example, the salinity of the Great Salt Lake in Utah, USA, is so high that through the evaporation of water salt crystals cover its shores. Some other ways in which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation.</onlyinclude>

=== Origin and composition ===
The feedstock for crystallisation is a solution with crystallisable ingredients, e.g. minerals or organic molecules. The majority of minerals and organic molecules crystallise easily, and the resulting crystals are generally of good quality, i.e. without visible defects. However, larger biochemical particles, like proteins, are often difficult to crystallise. The ease with which molecules will crystallise strongly depends on the intensity of either atomic forces (in the case of mineral substances), intermolecular forces (organic and biochemical substances) or intramolecular forces (biochemical substances).

=== Pre-treatment ===

==Process and technologies==
Crystallisation occurs in three major steps. The first is nucleation, the appearance of a crystalline phase from either a supercooled liquid or a supersaturated solvent. The second step is known as crystal growth, which is the increase in the size of particles and leads to a crystal state. An important feature of this step is that loose particles form layers at the crystal's surface and lodge themselves into open inconsistencies such as pores, cracks, etc.

Crystallisation is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering, crystallisation occurs in a crystalliser. Crystallisation is therefore related to precipitation, although the result is not amorphous or disordered, but a crystal.

Crystallisation and precipitation

[[File:2021 Great Salt Lake 06.jpg|alt=Picture showing a mound of salt crystals at the Great Salt Lake in Utah, USA|thumb|Salt crystals at Great Salt Lake, Utah, USA]]
<onlyinclude>'''Crystallisation''' is the formation of crystals from a solution. In a crystal, the atoms or molecules are highly organised into a solid repetitive structure. "A solution is a mixture of two or more species that form a homogenous single phase. Solutions are normally thought of in terms of liquids, however, solutions may include solids suspension. Typically, the term solution has come to mean a liquid solution consisting a solvent, which is a liquid, and a solute, which is a solid, at the conditions of interest. The solution to be ready for crystallization must be supersaturated."<ref>Sattar Al-Jibbouri "Effects of Additives in Solution Crystallization", 2002, https://sundoc.bibliothek.uni-halle.de/diss-online/02/03H046/prom.pdf</ref>

A simple example for crystallisation is the evaporation of the solvent. For example, the salinity of the Great Salt Lake in Utah, USA, is so high that through the evaporation of water salt crystals cover its shores. Some other ways in which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation.</onlyinclude>

==Feedstock==
[[File:NaCl octahedra and part of crystal.svg|alt=Graphic showing NaCl (table salt) crystal consisting of sodium and chlorine atoms|thumb|200x200px|NaCl (table salt) crystal consisting of sodium and chlorine atoms]]
=== Origin and composition ===
The feedstock for crystallisation is a solution with crystallisable ingredients, e.g. minerals or organic molecules. The majority of minerals and organic molecules crystallise easily, and the resulting crystals are generally of good quality, i.e. without visible defects. However, larger biochemical particles, like proteins, are often difficult to crystallise. The ease with which molecules will crystallise strongly depends on the intensity of either atomic forces (in the case of mineral substances), intermolecular forces (organic and biochemical substances) or intramolecular forces (biochemical substances).

=== Pre-treatment ===

==Process and technologies==
Crystallisation occurs in three major steps. The first is nucleation, the appearance of a crystalline phase from either a supercooled liquid or a supersaturated solvent. The second step is known as crystal growth, which is the increase in the size of particles and leads to a crystal state. An important feature of this step is that loose particles form layers at the crystal's surface and lodge themselves into open inconsistencies such as pores, cracks, etc.

Crystallisation is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering, crystallisation occurs in a crystalliser. Crystallisation is therefore related to precipitation, although the result is not amorphous or disordered, but a crystal.

Anaerobic digestion

2022-07-27T07:37:53Z

Stef Denayer: /* Dranco */

{{Infobox technology|Name=Anaerobic digestion|Category=[[Conversion]] ([[Conversion#Biochemical_processes_and_technologies|Biochemical processes and technologies]])|Feedstock=[[Biowaste]] in general, [[Food waste]], [[Garden and park waste]] (wood, leaves)|Product=Biogas and digestate}}
<onlyinclude>'''Anaerobic digestion''' is a process through which micro-organisms break down organic matter, such as animal manure, wastewater biosolids, and food wastes, in the absence of oxygen. Anaerobic digestion intended for biogas production takes place in a sealed tank (called an anaerobic digester), which is designed and constructed in various shapes and sizes specific to the site and feedstock conditions. These sealed vessels contain complex microbial communities that break down the waste and produce biogas and digestate (i.e., the solid and liquid material end-products of the process). The biogas can be used as a source of energy. The remaining digestate can be used as a fertiliser, or it can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.</onlyinclude>

== Feedstock ==
=== Origin and composition ===
Multiple organic materials can be combined in one digester, a practice called co-digestion. Co-digested materials include, amongst others, manure, food waste, energy crops, crop residues, and fats, oils, and greases (FOG) from restaurant grease traps.

=== Pre-treatment ===
Biomass is first separated from impurities as stones and glass. An agitator provides a good mixing between different biomass types to avoid strong changes in composition. The feed is a stirrable mixture and the dry matter content may be a maximum of 15-20% of the slurry. Co-substrates are often reduced in size by shredding before they are fed in order to make the contact surface of the biomass as large as possible.

For residual flows from the food industry, crop residues and manure, thermal and chemical pre-treatments are mainly applied. The most important effects of thermal pre-treatment are: reducing particle size, increasing solubility and improve the biodegradability. Additional advantages of thermal pre-treatment are: (1) higher loading of the digester is possible, (2) lower viscosity of the treated material which results in lower energy input for mixing the digester, (3) improved dewaterability of digestate and (4) sanitised product.

The following pre-treatments may be considered :

* [[Particle filtering]]
* [[Sizing]] (e.g. chipping, grinding)
* Thermal pre-treatment

== Process and technologies ==
=== Process ===
There are three basic anaerobic digestion processes, namely psychrophilic, mesophilic, and thermophilic, which take place over different temperature ranges. Psychrophilic digestion is a low temperature (<20°C) process. Mesophilic digestion takes place between 20 and 45°C, which can take a month or two to complete, and thermophilic digestion between 45 and 65°C, which is faster, but its micro-organisms are more sensitive. The majority of the agricultural biogas plants are operated at mesophilic temperatures. Thermophilic temperatures are applied mainly in large-scale centralised biogas plants with co-digestion<ref>{{Cite web|year=2021|title=Anaerobic digestion|e-pub date=2021|date accessed=6/9/2021|url=https://www.eubia.org/cms/wiki-biomass/anaerobic-digestion/}}</ref>. The process of anaerobic digestion takes place through four successive stages: hydrolysis, fermentation, acetogenesis, and methanogenesis.<ref>{{Cite journal|author=Junye Wang|year=2014|title=Decentralized biogas technology of anaerobic digestion and farm ecosystem: opportunities and challenges|journal=Fronties in Energy Research|volume=2|page=|doi=10.3389/fenrg.2014.00010}}</ref> In the hydrolysis step, the feedstock is broken down into soluble substrates (e.g., sugar and amino acids) by enzymes. Fermentation involves the conversion of sugar, amino acids, and fatty acids into ammonia, organic acids, hydrogen (H2) and CO2. In the acetogenesis step, volatile fatty acids are broken down into acetic acids, CO2 and H2. Finally, methanogenesis step converts acetate, formaldeyde, and H2 to CH4 and water<ref>{{Cite journal|author=Jay N. Meegoda, Brian Li, Kush Patel, Lily B. Wang|year=2018|title=A review of the Processes, Parameters, and Optimization of Anaerobic Digestion|journal=International Journal of Environmental Research and Public Health|volume=15|page=|doi=10.3390/ijerph15102224}}</ref>.
[[File:Anaerobic stages.png|thumb|Simplified scheme of pathways in anaerobic digestion (not own work)]]

Usually, the produced biogas must be dried and drained for condense water and biological or chemical cleaned for H2S, NH3 and trace elements. Further upgrading of the biogas to increase the CH4 content could be realized by membrane separation of CO2 and pressurising the biogas.
== Product ==
Anaerobic digestion produces two valuable outputs, namely biogas and digestate. Biogas is composed of methane (CH4), which is the primary component of natural gas, at a relatively high percentage (50 to 75%), carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and trace amounts of other gases. The energy in biogas can be used like natural gas to provide heat, generate electricity, and power cooling systems. Biogas can also be purified by removing the inert or low-value constituents (CO2, water, H2S, etc.) to generate renewable natural gas (RNG). This can be sold and injected into the natural gas distribution system, compressed and used as vehicle fuel, or processed further to generate alternative transportation fuel or other advanced biochemicals and bioproducts.

The digestate can be used in many beneficial applications provided that is is appropriately treated post processing. This could be in form of animal bedding, nutreint-rich fertilizer, organic-rich compost, or as soil amendment.

=== Post-treatment ===
The remaining digestate can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.

BioRenGaz has developed a new patented anaerobic digestion technology that is 4 times more efficient and much more compact than conventional biogas plants thanks to vertical silo design. The anaerobic filter uses a recycled and 100% renewable packing material to replace costly and polluting plastic packing. This medium provides an ecological habitat for the bacteria and enhances their performance. The solution is adapted for the treatment of liquid effluents and the great advantage, unlike other technologies, is that it can also valorize pulpy effluents like biowaste pulp. The bioreactors have lower operational costs and increased energy production by keeping the micro-organisms on the packing material, which allows producing 10% more biogas. The system is modular, so bioreactors can be built from a small scale and easily be expanded as needed. The Solution aims for the optimization of the economic and environmental model of energy and agronomic recovery of biowaste.

=== CCS ===
CCS Enegie-advies together with Greenmac developed the Bio-UP technology which is able to upgrade the produced biogas into green gas. CCS offers the Bio-UP technology via lease contracts or turn-key. The Bio-UP is a proven concept which already operates at "melkveeproefbedrijf De Marke".

Industrial fermentation

2022-07-27T07:16:49Z

Stef Denayer: /* Dranco */

{{Infobox technology|Name=Industrial fermentation|Feedstock=[[Garden and park waste]], [[food waste]]|Product=Biomass, bioproducts (e.g., enzymes, biopolymers, organic acids, alcohols)|Category=[[Conversion]] ([[Conversion#Biochemical_processes_and_technologies|Biochemical processes and technologies]])}}
<onlyinclude>'''Industrial fermentation''' is a biotechnological process which uses microorganisms (genetically modified or not), in particular bacteria, yeasts, fungi or algae, to make useful products. The cells are real "cell factories" for the industrial conversion of a wide range of renewable feedstocks into bulk chemicals, fine chemicals, platform chemicals, pharmaceutical ingredients, bio-fuels, bio-plastics, etc. It is a multidisciplinary technology and includes the integrated application of disciplines such as biochemistry, microbiology, molecular genetics and process technology to develop useful processes and products.</onlyinclude>

== Feedstock ==

=== Composition and origin ===
Depending on the type of microorganisms and its genetic modifications, a various range of feedstocks can be used. The most commonly used feedstocks are listed below:

==== Lignocellulose and cellulose ====
Lignocellulose is present in [[garden and park waste]]. Cellulose is present in [[food waste]] such as fruit and vegetable waste. Via [[hydrolysis]], which is usually performed through enzymatic or thermal treatment, fermentable sugars can be obtained from lignocellulose and cellulose.

==== Starch ====
Starch is present in [[food waste]] such as potatoes, corn, wheat or cassava. Starch can directly be utilized by amylase-producing microorganisms, particularly filamentous fungi. However, to allow its use in a wider range of fermentations, starch is usually converted into glucose or dextrins by enzymatic [[hydrolysis]].

==== Oils and Fat ====
Oils and fats are present in [[food waste]] such as gravy, used cooking oil and grease. They can directly be used as fermentation substrate. As they are not water soluble, extensive mixing is required to allow a good contact between the liquid droplets and the fermentation water phase.

==== Dairy waste ====
Whey, the liquid by-product of cheese manufacturing, is used as a source of fermentable carbohydrate and nitrogen.

==== Sugars ====
Sugar-rich waste streams can be derived from food industry waste, e.g., from the candy industry.

=== Pre-treatment ===
Depending on the type of feedstock and its purity, specific pre-treatment technologies are required to provide fermentable substrates to the microorganisms. Generally, this involves a [[Sizing|size reduction]] step, after which the milled biomass can be processed to separate the desired substrate by e.g., [[centrifugation]], filtration, evaporation or [[Crystallisation and precipitation|crystallization]].

In addition, it should be taken into account that some of the above mentioned feedstocks only provide the carbon source (which compose about 50% of the weight of most microorganisms), in that case also other nutrients such as nitrogen, phosphate and potassium need to be added.

==Process and technologies==

=== Microorganisms ===
Microorganisms used in industrial fermentations include: bacteria, yeast, fungi or algae. In practice, these are well-known, productive and harmless (GRAS - Generally Regarded As Safe) production organisms, equipped with the new genetic information, that are used to produce the desired products in high yield and efficiency. A major advantage is that these often genetically modified microorganisms do their work under controlled conditions in a fermenter or bio-reactor, carefully contained and separated from the outside world (contained environment). They cannot escape from the factory so that ecological problems or concerns regarding the release of genetically modified organisms in the environment are avoided.
[[File:Bioreactor principle.svg|thumb|257x257px|Schematic representation of an industrial fermentation bioreactor]]

=== Equipment ===
A typical industrial fermenter consists of an CSTR equipped with:

* an aeration and agitation system: to provide good mixing and availability of oxygen for the cell culture
* a temperature and pH control system: to assure optimal conditions for growth or production
* a foam control system: to avoid excessive foam formation
* sampling ports
* addition ports
* a cleaning and sterilization system: to avoid contamination with other, undesired microorganism
=== Operating conditions ===
As it involves living organisms, a fermentation process is typically conducted under mild conditions (pH and temperature). As a result, the energy consumption is relatively low as well as the capital and operating costs. However, fermentation technologies are complex and sensitive requiring careful control of quality and safety of the raw materials, process parameters, contamination, etc.

Industrial fermentations may be carried out as batch, fed-batch, or continuous culture systems. Batch and fed-batch operations are quite common, continuous fermentations being relatively rare <ref>{{Cite book|author=Y. Chisti|year=2014|book_title=Encyclopedia of Food Microbiology (Second Edition)|publisher=Science Direct}}</ref>.

=== Scale-up of industrial fermentations ===
Typically, a pure starter culture (or seed), maintained under carefully controlled conditions, is used to inoculate sterile petri dishes or liquid medium in the shake flasks. After sufficient growth, the preculture is used to inoculate the seed fermenter. Because industrial fermentations tend to be large (typically 1–250 m3), the inoculum is built up through several successively larger stages, to 5–10% of the working volume of the production fermenter. However, scale-up of a fermentation process is not straightforward as an increase in fermenter size affects the various process parameters in different ways. Therefore, ample expertise is required to find a compromise between all process parameters.

Depending on the type of microorganisms and its genetic modifications, a range of products can be synthesized. The most common products are listed and divided over two categories: (1) biomass, (2) bioproducts. In case of the latter, some products require complex genetic modifications.

=== Biomass ===

* Single Cell Protein
*Single Cell Oil
* Baker's yeast
* Lactic acid bacteria

=== Bioproducts ===

==== Enzymes ====

* Proteases
* Lipases
* Amylases
* Cellulases
* Peroxidases

==== Biopolymers ====

* Poly-hydroxyalkanoates (PHA)
* Polysaccharides: xanthan gum, dextran

==== Organic acids ====

* Acetic acid
*Lactic acid

* Citric acid
*Tartaric acid
*Fumaric acid

==== Alcohols ====

* Ethanol
*Butanol
*Glycerol
*Butanediol

==== Solvents ====

* Acetone

==== Pharmaceuticals ====

* Vitamins: vitamin C, B2, B12 ...
*Antibiotics: aminoglycosides, penicillins, cephalosporins, tetracyclines ...
*Hormones

==== Biocolorants ====

* cartenoids
*astaxanthins

==== Biosurfactants and bioemulsifiers ====

* glycolipids
*rhamnolipids

==== Amino-acids ====

* monosodium glutamate (MSG)
* Lysine
* Tryptophan
* Phenylalanine

== Post-treatment ==
The first step in the post-treatment of fermentation broth cultures, also known as '''downstream processing (DSP)''', is to remove the cells from the medium. This is typically performed by a solid-liquid separation technology, such, as [[centrifugation]] or [[membrane filtration]]. Each fraction can then undergo further processing, depending on whether the product is the biomass itself or an intra- or extracellular product. While intracellular products require cell disruption to release the products, extracellular products are solubilized in the depleted fermentation medium. Cell disruption techniques can be divided into mechanical methods (f.e. [[homogenisation]], [[Sizing|grinding]], [[Ultrasonication|sonication]], [[microwave treatment]], [[steam explosion]]) and non-mechanical methods (f.e. osmotic or temperature shock, [[Enzymatic processes|enzymatic destruction]]). To further purify and concentrate the products several methods can be used including [[chromatography]], [[solvent extraction]], [[Crystallisation and precipitation|crystallization]], [[distillation]], [[drying]] etc. The choice of purification technology is depending on the characteristics of the desired products.

Industrial fermentation

2022-07-25T13:02:10Z

Stef Denayer: /* POLYFOODS */

{{Infobox technology|Name=Industrial fermentation|Feedstock=[[Garden and park waste]], [[food waste]]|Product=Biomass, bioproducts (e.g., enzymes, biopolymers, organic acids, alcohols)|Category=[[Conversion]] ([[Conversion#Biochemical_processes_and_technologies|Biochemical processes and technologies]])}}
<onlyinclude>'''Industrial fermentation''' is a biotechnological process which uses microorganisms (genetically modified or not), in particular bacteria, yeasts, fungi or algae, to make useful products. The cells are real "cell factories" for the industrial conversion of a wide range of renewable feedstocks into bulk chemicals, fine chemicals, platform chemicals, pharmaceutical ingredients, bio-fuels, bio-plastics, etc. It is a multidisciplinary technology and includes the integrated application of disciplines such as biochemistry, microbiology, molecular genetics and process technology to develop useful processes and products.</onlyinclude>

== Feedstock ==

=== Composition and origin ===
Depending on the type of microorganisms and its genetic modifications, a various range of feedstocks can be used. The most commonly used feedstocks are listed below:

==== Lignocellulose and cellulose ====
Lignocellulose is present in [[garden and park waste]]. Cellulose is present in [[food waste]] such as fruit and vegetable waste. Via [[hydrolysis]], which is usually performed through enzymatic or thermal treatment, fermentable sugars can be obtained from lignocellulose and cellulose.

==== Starch ====
Starch is present in [[food waste]] such as potatoes, corn, wheat or cassava. Starch can directly be utilized by amylase-producing microorganisms, particularly filamentous fungi. However, to allow its use in a wider range of fermentations, starch is usually converted into glucose or dextrins by enzymatic [[hydrolysis]].

==== Oils and Fat ====
Oils and fats are present in [[food waste]] such as gravy, used cooking oil and grease. They can directly be used as fermentation substrate. As they are not water soluble, extensive mixing is required to allow a good contact between the liquid droplets and the fermentation water phase.

==== Dairy waste ====
Whey, the liquid by-product of cheese manufacturing, is used as a source of fermentable carbohydrate and nitrogen.

==== Sugars ====
Sugar-rich waste streams can be derived from food industry waste, e.g., from the candy industry.

=== Pre-treatment ===
Depending on the type of feedstock and its purity, specific pre-treatment technologies are required to provide fermentable substrates to the microorganisms. Generally, this involves a [[Sizing|size reduction]] step, after which the milled biomass can be processed to separate the desired substrate by e.g., [[centrifugation]], filtration, evaporation or [[Crystallisation and precipitation|crystallization]].

In addition, it should be taken into account that some of the above mentioned feedstocks only provide the carbon source (which compose about 50% of the weight of most microorganisms), in that case also other nutrients such as nitrogen, phosphate and potassium need to be added.

==Process and technologies==

=== Microorganisms ===
Microorganisms used in industrial fermentations include: bacteria, yeast, fungi or algae. In practice, these are well-known, productive and harmless (GRAS - Generally Regarded As Safe) production organisms, equipped with the new genetic information, that are used to produce the desired products in high yield and efficiency. A major advantage is that these often genetically modified microorganisms do their work under controlled conditions in a fermenter or bio-reactor, carefully contained and separated from the outside world (contained environment). They cannot escape from the factory so that ecological problems or concerns regarding the release of genetically modified organisms in the environment are avoided.
[[File:Bioreactor principle.svg|thumb|257x257px|Schematic representation of an industrial fermentation bioreactor]]

=== Equipment ===
A typical industrial fermenter consists of an CSTR equipped with:

* an aeration and agitation system: to provide good mixing and availability of oxygen for the cell culture
* a temperature and pH control system: to assure optimal conditions for growth or production
* a foam control system: to avoid excessive foam formation
* sampling ports
* addition ports
* a cleaning and sterilization system: to avoid contamination with other, undesired microorganism
=== Operating conditions ===
As it involves living organisms, a fermentation process is typically conducted under mild conditions (pH and temperature). As a result, the energy consumption is relatively low as well as the capital and operating costs. However, fermentation technologies are complex and sensitive requiring careful control of quality and safety of the raw materials, process parameters, contamination, etc.

Industrial fermentations may be carried out as batch, fed-batch, or continuous culture systems. Batch and fed-batch operations are quite common, continuous fermentations being relatively rare <ref>{{Cite book|author=Y. Chisti|year=2014|book_title=Encyclopedia of Food Microbiology (Second Edition)|publisher=Science Direct}}</ref>.

=== Scale-up of industrial fermentations ===
Typically, a pure starter culture (or seed), maintained under carefully controlled conditions, is used to inoculate sterile petri dishes or liquid medium in the shake flasks. After sufficient growth, the preculture is used to inoculate the seed fermenter. Because industrial fermentations tend to be large (typically 1–250 m3), the inoculum is built up through several successively larger stages, to 5–10% of the working volume of the production fermenter. However, scale-up of a fermentation process is not straightforward as an increase in fermenter size affects the various process parameters in different ways. Therefore, ample expertise is required to find a compromise between all process parameters.
==Products==
Depending on the type of microorganisms and its genetic modifications, a range of products can be synthesized. The most common products are listed and divided over two categories: (1) biomass, (2) bioproducts. In case of the latter, some products require complex genetic modifications.

*Butanol
*Glycerol

==== Biosurfactants and bioemulsifiers ====

* glycolipids
*rhamnolipids

==== Amino-acids ====

* monosodium glutamate (MSG)

As a result, the energy consumption is relatively low as well as the capital and operating costs. However, fermentation technologies are complex and sensitive requiring careful control of quality and safety of the raw materials, process parameters, contamination, etc.

Industrial fermentations may be carried out as batch, fed-batch, or continuous culture systems. Batch and fed-batch operations are quite common, continuous fermentations being relatively rare <ref>{{Cite book|author=Y. Chisti|year=2014|book_title=Encyclopedia of Food Microbiology (Second Edition)|publisher=Science Direct}}</ref>.

=== Scale-up of industrial fermentations ===
Typically, a pure starter culture (or seed), maintained under carefully controlled conditions, is used to inoculate sterile petri dishes or liquid medium in the shake flasks. After sufficient growth, the preculture is used to inoculate the seed fermenter. Because industrial fermentations tend to be large (typically 1–250 m3), the inoculum is built up through several successively larger stages, to 5–10% of the working volume of the production fermenter. However, scale-up of a fermentation process is not straightforward as an increase in fermenter size affects the various process parameters in different ways. Therefore, ample expertise is required to find a compromise between all process parameters.
==Products==
Depending on the type of microorganisms and its genetic modifications, a range of products can be synthesized. The most common products are listed and divided over two categories: (1) biomass, (2) bioproducts. In case of the latter, some products require complex genetic modifications.

=== Biomass ===

* Single Cell Protein
*Single Cell Oil
* Baker's yeast
* Lactic acid bacteria

=== Bioproducts ===

==== Enzymes ====

* Proteases
* Lipases
* Amylases
* Cellulases
* Peroxidases

==== Biopolymers ====

* Poly-hydroxyalkanoates (PHA)
* Polysaccharides: xanthan gum, dextran

==== Organic acids ====

* Acetic acid
*Lactic acid

* Citric acid
*Tartaric acid
*Fumaric acid

==== Alcohols ====

* Ethanol
*Butanol
*Glycerol
*Butanediol

==== Solvents ====

* Acetone

==== Pharmaceuticals ====

* Vitamins: vitamin C, B2, B12 ...
*Antibiotics: aminoglycosides, penicillins, cephalosporins, tetracyclines ...
*Hormones

==== Biocolorants ====

* cartenoids
*astaxanthins

==== Biosurfactants and bioemulsifiers ====

* glycolipids
*rhamnolipids

==== Amino-acids ====

* monosodium glutamate (MSG)
* Lysine
* Tryptophan
* Phenylalanine

== Post-treatment ==
The first step in the post-treatment of fermentation broth cultures, also known as '''downstream processing (DSP)''', is to remove the cells from the medium. This is typically performed by a solid-liquid separation technology, such, as [[centrifugation]] or [[membrane filtration]]. Each fraction can then undergo further processing, depending on whether the product is the biomass itself or an intra- or extracellular product. While intracellular products require cell disruption to release the products, extracellular products are solubilized in the depleted fermentation medium. Cell disruption techniques can be divided into mechanical methods (f.e. [[homogenisation]], [[Sizing|grinding]], [[Ultrasonication|sonication]], [[microwave treatment]], [[steam explosion]]) and non-mechanical methods (f.e. osmotic or temperature shock, [[Enzymatic processes|enzymatic destruction]]). To further purify and concentrate the products several methods can be used including [[chromatography]], [[solvent extraction]], [[Crystallisation and precipitation|crystallization]], [[distillation]], [[drying]] etc. The choice of purification technology is depending on the characteristics of the desired products.

Stef Denayer: /* Technology providers */

{{Infobox technology|Name=Ioniq Liquids|Category=[[Pre-processing]] ([[Pre-processing#Chemical_processes_and_technologies|Chemical processes and technologies]])|Feedstock=Lignocellulosic biowaste|Product=Lignin}}
<onlyinclude>'''Ionic liquids''' are organic salts that are liquid at room temperature. Because they are salts, they show no volatility. Moreover, they show a high thermal stability as well. Both properties allows them to be used as green solvents and as and alternative to volatile organic compounds. These properties are useful in the pre-treatment of lignocellulosic material by dissolving the material and separating the lignin.</onlyinclude><ref name=":0">{{Cite journal|title=Ionic liquid-mediated selective extraction of lignin from wood leading to enhanced enzymatic cellulose hydrolysis|year=2009-04-01|author=Sang Hyun Lee, Thomas V.

Dordick|journal=Biotechnology and Bioengineering|volume=102|issue=5|page=1368–1376|doi=10.1002/bit.22179}}</ref> Lignin streams can also be dissolved to allow for further processing. 

==Feedstock==

=== Origin and composition ===
Ionic liquids are capable of dissolving lignocellulosic biomass. Examples for biomass include corn stalks, rice straw, bagasse, pine wood, and spruce wood.<ref name=":0" /> Next to lignocellulosic biomass, lignin streams can be dissolved for further processing.

=== Pre-treatment ===

* [[Sizing|Seizing]]

==Process and technologies==
Ionic liquids have been shown to dissolve lignin or cellulose, because it can decrease the crystallinity and therefore makes it more accessible for further processing. Moreover, a full dissolution of lignocellulosic biomass can be used to extract the lignin. The technology can also be combined with [[hydrolysis]] to make the cellulose available as sugars for further processing.<ref name=":0" /> Cellulose can be recovered from the solution by the addition of water, ethanol, or acetone, while the ionic liquid can be recovered by pervaporation, reverse osmosis, salting out, or ionic exchange.<ref>{{Cite journal|title=Biomass pretreatment: Fundamentals toward application|year=2011-11-01|journal=Biotechnology Advances|volume=29|issue=6|page=675–685|doi=10.1016/j.biotechadv.2011.05.005|author=Valery B. Agbor, Nazim Cicek, Richard Sparling, Alex Berlin, David B. Levin}}</ref>

==Product==
The final product of the process depends on the exact combination of technologies. Generally, a large part of the lignin can be extracted from lignocellulosic material. Depending on the process properties it could also be that cellulose is more easily available for further processing.

=== Post-treatment===
There are no post-treatment technologies known at the moment.

[[File:Compounding-en.png|thumb|Compounding process]]
[[File:Türinnenverkleidung Hanf-PP nova.jpg|thumb|Interior carpeting of a car's door made by a biocomposite of hemp fibres and polyethylene]]
<onlyinclude>In '''Biocomposite processing''' bio-based materials are processed to composite materials. Normally, these materials consist of a polymeric matrix that can be fossil- or bio-based. Bio-based materials fixed in this are for example wood dust, natural fibres, straws, rice husks, nutshells and others. Best-known biocomposites are Wood-Plastic-Composites (WPC) or Natural-fibre reinforced materials.</onlyinclude>

== Feedstock ==

=== Origin and composition ===
Biocomposite processing is a secondary process where a composite material is formed by a matrix (resin) and a reinforcement of natural fibers or filling with other biomass-based materials like wood dust, agricultural wastes or sidestreams from food processing like nutshells or rice husks. In principal, the matrix can be a bio-based or a petro-based resin, but normally polymers like polypropylene, polyethylene or epoxys are used as matrix material.

=== Pre-treatment ===
The retting process, carried out with warm inoculated water, has been evaluated as a potential method to modify the structure of fibers in order to prepare polymeric biocomposites.<ref>{{Cite web|Author=Sisti, Laura; Totaro, Grazia; Vannini, Micaela; Fabbri, Paola; Kalia, Susheel; Zatta, Alessandro; Celli, Annamaria|year=2016|title=Evaluation of the retting process as a pre-treatment of vegetable fibers for the preparation of high-performance polymer biocomposites|e-pub date=2016/03/01|date accessed=14/02/2022|url=https://www.researchgate.net/publication/285782567_Evaluation_of_the_retting_process_as_a_pre-treatment_of_vegetable_fibers_for_the_preparation_of_high-performance_polymer_biocomposites}}</ref>

== Process and technologies ==
=== Types of biocomposites ===
There are several types of biocomposites on the market that normally have a fossil-based matrix with natural fibre reinforcement or wood filling. In principal also the matrix can be bio-based consisting of bio-based polymers like PLA, bio-PE, biogenic epoxis or PHAs.

=== Processing technologies ===
In the compounding process the matrix materials are melted and then mixed with fillers, plasticisers, additives and fibres to a homogeneous formulate that can be given into a screw extruder. This produces an extrudate that will be cooled down in a water bath and then cutted into composite granules. The granules can be used to produce several types of products e.g. by injection moulding or other material processing technologies.

== Product ==
Products of Biocomposite processing are different kinds of biocomposites.

Industrial fermentation

2022-06-16T11:35:54Z

Stef Denayer: /* Amphi-Star */

{{Infobox technology|Name=Industrial fermentation|Feedstock=[[Garden and park waste]], [[food waste]]|Product=Biomass, bioproducts (e.g., enzymes, biopolymers, organic acids, alcohols)|Category=[[Conversion]] ([[Conversion#Biochemical_processes_and_technologies|Biochemical processes and technologies]])}}
<onlyinclude>'''Industrial fermentation''' is a biotechnological process which uses microorganisms (genetically modified or not), in particular bacteria, yeasts, fungi or algae, to make useful products. The cells are real "cell factories" for the industrial conversion of a wide range of renewable feedstocks into bulk chemicals, fine chemicals, platform chemicals, pharmaceutical ingredients, bio-fuels, bio-plastics, etc. It is a multidisciplinary technology and includes the integrated application of disciplines such as biochemistry, microbiology, molecular genetics and process technology to develop useful processes and products.</onlyinclude>

== Feedstock ==

=== Composition and origin ===
Depending on the type of microorganisms and its genetic modifications, a various range of feedstocks can be used. The most commonly used feedstocks are listed below:

==== Lignocellulose and cellulose ====
Lignocellulose is present in [[garden and park waste]]. Cellulose is present in [[food waste]] such as fruit and vegetable waste. Via [[hydrolysis]], which is usually performed through enzymatic or thermal treatment, fermentable sugars can be obtained from lignocellulose and cellulose.

==== Starch ====
Starch is present in [[food waste]] such as potatoes, corn, wheat or cassava. Starch can directly be utilized by amylase-producing microorganisms, particularly filamentous fungi. However, to allow its use in a wider range of fermentations, starch is usually converted into glucose or dextrins by enzymatic [[hydrolysis]].

==== Oils and Fat ====
Oils and fats are present in [[food waste]] such as gravy, used cooking oil and grease. They can directly be used as fermentation substrate. As they are not water soluble, extensive mixing is required to allow a good contact between the liquid droplets and the fermentation water phase.

==== Dairy waste ====
Whey, the liquid by-product of cheese manufacturing, is used as a source of fermentable carbohydrate and nitrogen.

==== Sugars ====
Sugar-rich waste streams can be derived from food industry waste, e.g., from the candy industry.

=== Pre-treatment ===
Depending on the type of feedstock and its purity, specific pre-treatment technologies are required to provide fermentable substrates to the microorganisms. Generally, this involves a [[Sizing|size reduction]] step, after which the milled biomass can be processed to separate the desired substrate by e.g., [[centrifugation]], filtration, evaporation or [[Crystallisation and precipitation|crystallization]].

In addition, it should be taken into account that some of the above mentioned feedstocks only provide the carbon source (which compose about 50% of the weight of most microorganisms), in that case also other nutrients such as nitrogen, phosphate and potassium need to be added.

==Process and technologies==

=== Microorganisms ===
Microorganisms used in industrial fermentations include: bacteria, yeast, fungi or algae. In practice, these are well-known, productive and harmless (GRAS - Generally Regarded As Safe) production organisms, equipped with the new genetic information, that are used to produce the desired products in high yield and efficiency. A major advantage is that these often genetically modified microorganisms do their work under controlled conditions in a fermenter or bio-reactor, carefully contained and separated from the outside world (contained environment). They cannot escape from the factory so that ecological problems or concerns regarding the release of genetically modified organisms in the environment are avoided.

=== Equipment ===
A typical industrial fermenter consists of an CSTR equipped with:

* an aeration and agitation system: to provide good mixing and availability of oxygen for the cell culture
* a temperature and pH control system: to assure optimal conditions for growth or production
* a foam control system: to avoid excessive foam formation
* sampling ports
* addition ports
* a cleaning and sterilization system: to avoid contamination with other, undesired microorganism
=== Operating conditions ===
As it involves living organisms, a fermentation process is typically conducted under mild conditions (pH and temperature). As a result, the energy consumption is relatively low as well as the capital and operating costs. However, fermentation technologies are complex and sensitive requiring careful control of quality and safety of the raw materials, process parameters, contamination, etc.

Industrial fermentations may be carried out as batch, fed-batch, or continuous culture systems. Batch and fed-batch operations are quite common, continuous fermentations being relatively rare <ref>{{Cite book|author=Y. Chisti|year=2014|book_title=Encyclopedia of Food Microbiology (Second Edition)|publisher=Science Direct}}</ref>.

=== Scale-up of industrial fermentations ===
Typically, a pure starter culture (or seed), maintained under carefully controlled conditions, is used to inoculate sterile petri dishes or liquid medium in the shake flasks. After sufficient growth, the preculture is used to inoculate the seed fermenter. Because industrial fermentations tend to be large (typically 1–250 m3), the inoculum is built up through several successively larger stages, to 5–10% of the working volume of the production fermenter. However, scale-up of a fermentation process is not straightforward as an increase in fermenter size affects the various process parameters in different ways. Therefore, ample expertise is required to find a compromise between all process parameters.
==Products==
Depending on the type of microorganisms and its genetic modifications, a range of products can be synthesized. The most common products are listed and divided over two categories: (1) biomass, (2) bioproducts. In case of the latter, some products require complex genetic modifications.

=== Biomass ===

* Single Cell Protein
*Single Cell Oil
* Baker's yeast
* Lactic acid bacteria

=== Bioproducts ===

==== Enzymes ====

* Proteases
* Lipases
* Amylases
* Cellulases
* Peroxidases

==== Biopolymers ====

* Poly-hydroxyalkanoates (PHA)
* Polysaccharides: xanthan gum, dextran

==== Organic acids ====

* Acetic acid
*Lactic acid

* Citric acid
*Tartaric acid
*Fumaric acid

==== Alcohols ====

* Ethanol
*Butanol
*Glycerol
*Butanediol

==== Solvents ====

* Acetone

==== Pharmaceuticals ====

* Vitamins: vitamin C, B2, B12 ...
*Antibiotics: aminoglycosides, penicillins, cephalosporins, tetracyclines ...
*Hormones

==== Biocolorants ====

* cartenoids
*astaxanthins

==== Biosurfactants and bioemulsifiers ====

* glycolipids
*rhamnolipids

==== Amino-acids ====

* monosodium glutamate (MSG)
* Lysine
* Tryptophan
* Phenylalanine

== Post-treatment ==
The first step in the post-treatment of fermentation broth cultures, also known as '''downstream processing (DSP)''', is to remove the cells from the medium. This is typically performed by a solid-liquid separation technology, such, as [[centrifugation]] or [[membrane filtration]]. Each fraction can then undergo further processing, depending on whether the product is the biomass itself or an intra- or extracellular product. While intracellular products require cell disruption to release the products, extracellular products are solubilized in the depleted fermentation medium. Cell disruption techniques can be divided into mechanical methods (f.e. [[homogenisation]], [[Sizing|grinding]], [[Ultrasonication|sonication]], [[microwave treatment]], [[steam explosion]]) and non-mechanical methods (f.e. osmotic or temperature shock, [[Enzymatic processes|enzymatic destruction]]). To further purify and concentrate the products several methods can be used including [[chromatography]], [[solvent extraction]], [[Crystallisation and precipitation|crystallization]], [[distillation]], [[drying]] etc. The choice of purification technology is depending on the characteristics of the desired products.

Industrial fermentation

{{Infobox technology|Name=Industrial fermentation|Feedstock=[[Garden and park waste]], [[food waste]]|Product=Biomass, bioproducts (e.g., enzymes, biopolymers, organic acids, alcohols)|Category=[[Conversion]] ([[Conversion#Biochemical_processes_and_technologies|Biochemical processes and technologies]])}}
<onlyinclude>'''Industrial fermentation''' is a biotechnological process which uses microorganisms (genetically modified or not), in particular bacteria, yeasts, fungi or algae, to make useful products. The cells are real "cell factories" for the industrial conversion of a wide range of renewable feedstocks into bulk chemicals, fine chemicals, platform chemicals, pharmaceutical ingredients, bio-fuels, bio-plastics, etc. It is a multidisciplinary technology and includes the integrated application of disciplines such as biochemistry, microbiology, molecular genetics and process technology to develop useful processes and products.</onlyinclude>

== Feedstock ==

=== Composition and origin ===
Depending on the type of microorganisms and its genetic modifications, a various range of feedstocks can be used. The most commonly used feedstocks are listed below:

==== Lignocellulose and cellulose ====
Lignocellulose is present in [[garden and park waste]]. Cellulose is present in [[food waste]] such as fruit and vegetable waste. Via [[hydrolysis]], which is usually performed through enzymatic or thermal treatment, fermentable sugars can be obtained from lignocellulose and cellulose.

==== Starch ====
Starch is present in [[food waste]] such as potatoes, corn, wheat or cassava. Starch can directly be utilized by amylase-producing microorganisms, particularly filamentous fungi. However, to allow its use in a wider range of fermentations, starch is usually converted into glucose or dextrins by enzymatic [[hydrolysis]].

==== Oils and Fat ====
Oils and fats are present in [[food waste]] such as gravy, used cooking oil and grease. They can directly be used as fermentation substrate. As they are not water soluble, extensive mixing is required to allow a good contact between the liquid droplets and the fermentation water phase.

==== Dairy waste ====
Whey, the liquid by-product of cheese manufacturing, is used as a source of fermentable carbohydrate and nitrogen.

==== Sugars ====
Sugar-rich waste streams can be derived from food industry waste, e.g., from the candy industry.

=== Pre-treatment ===
Depending on the type of feedstock and its purity, specific pre-treatment technologies are required to provide fermentable substrates to the microorganisms. Generally, this involves a [[Sizing|size reduction]] step, after which the milled biomass can be processed to separate the desired substrate by e.g., [[centrifugation]], filtration, evaporation or [[Crystallisation and precipitation|crystallization]].

In addition, it should be taken into account that some of the above mentioned feedstocks only provide the carbon source (which compose about 50% of the weight of most microorganisms), in that case also other nutrients such as nitrogen, phosphate and potassium need to be added.

==Process and technologies==

=== Microorganisms ===
Microorganisms used in industrial fermentations include: bacteria, yeast, fungi or algae. In practice, these are well-known, productive and harmless (GRAS - Generally Regarded As Safe) production organisms, equipped with the new genetic information, that are used to produce the desired products in high yield and efficiency. A major advantage is that these often genetically modified microorganisms do their work under controlled conditions in a fermenter or bio-reactor, carefully contained and separated from the outside world (contained environment).

Drying

2022-02-21T15:56:56Z

Stef Denayer: /* Pre-treatment */

{{Infobox technology
| Feedstock = Biowaste including liquids
| Product = Dry biomass
|Name=Drying|Category=[[Pre-processing]] ([[Pre-processing#Separation_technologies|Separation technologies]]), [[Post-processing]] ([[Post-processing#Separation_technologies|Separation technologies]])}}
<onlyinclude>

'''Drying''' technologies are based on the vaporisation/evaporation or sublimation of different liquids or solids under different gas atmospheres and physical conditions resulting in dry products or products with a desired humidity.

</onlyinclude>

== Feedstock ==

=== Origin and composition ===

=== Pre-treatment ===
In view of the energy costs involved in drying, this technology is of limited use in pre-treatment. The need to dry biomass feedstocks before they can for example be gasified, can place a large energy and capital cost burden on small-to-medium scale biomass gasification plants for the production of heat and power. Drying may not always be unavoidable, but as biomass moisture content to the gasifier increases, the quality of the product gas deteriorates along with the overall performance of the whole system.

== Process and technologies ==

=== Air drying ===
Process that involves the evaporation of liquids under an oxygen atmosphere. The exchange of oxygen with low humidity accelerates this process, but may lead to an (unwanted) oxidation of the product.

=== Nitrogen drying ===
Process that involves the evaporation of liquids under an nitrogen atmosphere. The exchange of nitrogen accelerates this process. Since nitrogen is an inert gas, unwanted reactions such as oxidation of the product are avoided.

=== Freeze drying ===
Also known as lyophilisation. The technology represents a low temperature and pressure dehydration process that involves freezing the product, lowering pressure ("vacuum"), then removing the ice by sublimation and condensing.

=== Thermal drying ===
Process that involves the vaporisation/evaporation of liquids through the application of heat under different atmospheres. With increasing application of heat, the process can be accelerated. Very high temperatures may lead to unwanted reactions of the product. Examples for thermal drying technologies are flash (pneumatic) drying, radiative drying, solar drying, drum drying, and supercritical drying.

=== Vacuum drying ===
Process that involves the evaporation of liquids under a vacuum atmosphere. The vacuum atmosphere allows the evaporation of liquids at lower temperatures than under atmospheric pressure.

== Product ==

=== Post-treatment ===
Drying is a widely used process in industry worldwide, with many different reasons: to save weight, to make transport easier, to extend the shelf life of food, to obtain a product that can be further processed, etc.

The importance of drying efficiency has increased significantly due to high energy costs and increasingly stringent customer quality requirements.

Compost is easier to handle than manure and other raw organic materials, stores well and is odor-free. Composting is an ancient technology, practiced today at every scale from the backyard compost pile to large commercial operations. </onlyinclude>

== Feedstock ==

=== Origin and composition ===
Composts can be made from most organic by-products. Common feedstocks are poultry, hog and cattle manures, food processing wastes, sewage sludge, municipal leaves, brush and grass clippings, sawdust, and other by-products of wood processing.

Ideally, several raw materials should be mixed together to create the "ideal" range of conditions, which are as follows:
{| class="wikitable"
|+
!Condition
!Ideal
|-
|C:N ratios of combined feedstocks
|25-35:1
|-
|Moisture content
|45-60 wt.%
|-
|Available oxygen concentration
|>10% or more
|-
|Feedstock particle size
|Variable
|-
|pH
|6.5-8.0
|-
|temperature
|54-60°C
|}

=== Pre-treatment ===
The pre-treatment usually starts with a [[sizing]] activity by [[Sizing#Chipping|chipping]] the feedstock and subsequently the necessary structural material is mixed in. The purpose of the structural material is to prevent the organic material from caking together. The feedstock mixture is also stripped of metals by means of an electromagnet. In preparation for intensive ripening, a homogeneous airy material is obtained.

== Process ==
Composting occurs through the activity of micro-organisms naturally found in soils. Under natural conditions, earthworms, nematodes and soil insects do most of the initial mechanical breakdown of organic materials into smaller particles. Under controlled conditions, composters break down large particles through grinding or chopping. Once optimal physical conditions are established, soil bacteria, fungi, actinomycetes and protozoa colonize the organic material and initiate the composting process. These mesophilic organisms function best at warm temperatures (10-45°C). As temperatures in the compost pile increase, thermophiles (i.e., micro-organisms that thrive at temperatures above 45°C) take over. In the active "thermophilic" phase, temperatures of 54-65°C are reached which is high enough to kill pathogens and weed seeds and to break down phytotoxic compounds (i.e., organic compounds toxic to plants). After the active composting phase, temperatures gradually decline to around 37°C. The mesophiles recolonize the pile and the compost enters the "curing phase". During curing, organic materials continue to decompose and are converted to biologically stable humic substances (i.e., the mature or finished compost). There is no clear defined time for curing. Common practices in commercial composting operations range from one to four months.

== Product ==
The final product is a valuable soil resource named compost. Compost can replace materials like peat and topsoil as seed starters, container mixes, soil amendments, mulches and natural fertilizers.

=== Post-treatment ===
In post treatment, the compost is screened at small sizes (up to 12 mm) and any remaining impurities are removed. The coarse fraction is reused in composting as a structural material.

Anaerobic digestion

2022-02-09T10:47:31Z

Stef Denayer:

{{Infobox technology|Name=Anaerobic digestion|Category=Conversion Technologies|Feedstock=[[Biowaste]] in general, [[Food waste]], [[Garden and park waste]] (wood, leaves)|Product=Biogas and digestate}}
<onlyinclude>'''Anaerobic digestion''' is a process through which micro-organisms break down organic matter, such as animal manure, wastewater biosolids, and food wastes, in the absence of oxygen. Anaerobic digestion intended for biogas production takes place in a sealed tank (called an anaerobic digester), which is designed and constructed in various shapes and sizes specific to the site and feedstock conditions. These sealed vessels contain complex microbial communities that break down the waste and produce biogas and digestate (i.e., the solid and liquid material end-products of the process). The biogas can be used as a source of energy. The remaining digestate can be used as a fertiliser, or it can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.</onlyinclude>

== Feedstock ==
=== Origin and composition ===
Multiple organic materials can be combined in one digester, a practice called co-digestion. Co-digested materials include, amongst others, manure, food waste, energy crops, crop residues, and fats, oils, and greases (FOG) from restaurant grease traps.

=== Pre-treatment ===
Biomass is first separated from impurities as stones and glass. An agitator provides a good mixing between different biomass types to avoid strong changes in composition. The feed is a stirrable mixture and the dry matter content may be a maximum of 15-20% of the slurry. Co-substrates are often reduced in size by shredding before they are fed in order to make the contact surface of the biomass as large as possible.

For residual flows from the food industry, crop residues and manure, thermal and chemical pre-treatments are mainly applied. The most important effects of thermal pre-treatment are: reducing particle size, increasing solubility and improve the biodegradability. Additional advantages of thermal pre-treatment are: (1) higher loading of the digester is possible, (2) lower viscosity of the treated material which results in lower energy input for mixing the digester, (3) improved dewaterability of digestate and (4) sanitised product.

The following pre-treatments may be considered :

* [[Particle filtering]]
* [[Sizing]] (e.g. chipping, grinding)
* Thermal pre-treatment

== Process and technologies ==
=== Process ===
There are three basic anaerobic digestion processes, namely psychrophilic, mesophilic, and thermophilic, which take place over different temperature ranges. Psychrophilic digestion is a low temperature (<20°C) process. Mesophilic digestion takes place between 20 and 45°C, which can take a month or two to complete, and thermophilic digestion between 45 and 65°C, which is faster, but its micro-organisms are more sensitive. The majority of the agricultural biogas plants are operated at mesophilic temperatures. Thermophilic temperatures are applied mainly in large-scale centralised biogas plants with co-digestion<ref>{{Cite web|year=2021|title=Anaerobic digestion|e-pub date=2021|date accessed=6/9/2021|url=https://www.eubia.org/cms/wiki-biomass/anaerobic-digestion/}}</ref>. The process of anaerobic digestion takes place through four successive stages: hydrolysis, fermentation, acetogenesis, and methanogenesis.<ref>{{Cite journal|author=Junye Wang|year=2014|title=Decentralized biogas technology of anaerobic digestion and farm ecosystem: opportunities and challenges|journal=Fronties in Energy Research|volume=2|page=|doi=10.3389/fenrg.2014.00010}}</ref> In the hydrolysis step, the feedstock is broken down into soluble substrates (e.g., sugar and amino acids) by enzymes. Fermentation involves the conversion of sugar, amino acids, and fatty acids into ammonia, organic acids, hydrogen (H2) and CO2. In the acetogenesis step, volatile fatty acids are broken down into acetic acids, CO2 and H2. Finally, methanogenesis step converts acetate, formaldeyde, and H2 to CH4 and water<ref>{{Cite journal|author=Jay N. Meegoda, Brian Li, Kush Patel, Lily B. Wang|year=2018|title=A review of the Processes, Parameters, and Optimization of Anaerobic Digestion|journal=International Journal of Environmental Research and Public Health|volume=15|page=|doi=10.3390/ijerph15102224}}</ref>.
[[File:Anaerobic stages.png|thumb|Simplified scheme of pathways in anaerobic digestion (not own work)]]

Usually, the produced biogas must be dried and drained for condense water and biological or chemical cleaned for H2S, NH3 and trace elements. Further upgrading of the biogas to increase the CH4 content could be realized by membrane separation of CO2 and pressurising the biogas.
== Product ==
Anaerobic digestion produces two valuable outputs, namely biogas and digestate. Biogas is composed of methane (CH4), which is the primary component of natural gas, at a relatively high percentage (50 to 75%), carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and trace amounts of other gases. The energy in biogas can be used like natural gas to provide heat, generate electricity, and power cooling systems. Biogas can also be purified by removing the inert or low-value constituents (CO2, water, H2S, etc.) to generate renewable natural gas (RNG). This can be sold and injected into the natural gas distribution system, compressed and used as vehicle fuel, or processed further to generate alternative transportation fuel or other advanced biochemicals and bioproducts.

The digestate can be used in many beneficial applications provided that is is appropriately treated post processing. This could be in form of animal bedding, nutreint-rich fertilizer, organic-rich compost, or as soil amendment.

=== Post-treatment ===
The remaining digestate can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.

Anaerobic digestion

{{Infobox technology|Name=Anaerobic digestion|Category=Conversion Technologies|Feedstock=Biowaste in general|Product=Biogas and digestate}}
<onlyinclude>'''Anaerobic digestion''' is a process through which micro-organisms break down organic matter, such as animal manure, wastewater biosolids, and food wastes, in the absence of oxygen. Anaerobic digestion intended for biogas production takes place in a sealed tank (called an anaerobic digester), which is designed and constructed in various shapes and sizes specific to the site and feedstock conditions. These sealed vessels contain complex microbial communities that break down the waste and produce biogas and digestate (i.e., the solid and liquid material end-products of the process). The biogas can be used as a source of energy. The remaining digestate can be used as a fertiliser, or it can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.</onlyinclude>

== Feedstock ==
=== Origin and composition ===
Multiple organic materials can be combined in one digester, a practice called co-digestion. Co-digested materials include, amongst others, manure, food waste, energy crops, crop residues, and fats, oils, and greases (FOG) from restaurant grease traps.

=== Pre-treatment ===
Biomass is first separated from impurities as stones and glass. An agitator provides a good mixing between different biomass types to avoid strong changes in composition. The feed is a stirrable mixture and the dry matter content may be a maximum of 15-20% of the slurry. Co-substrates are often reduced in size by shredding before they are fed in order to make the contact surface of the biomass as large as possible.

For residual flows from the food industry, crop residues and manure, thermal and chemical pre-treatments are mainly applied. The most important effects of thermal pre-treatment are: reducing particle size, increasing solubility and improve the biodegradability. Additional advantages of thermal pre-treatment are: (1) higher loading of the digester is possible, (2) lower viscosity of the treated material which results in lower energy input for mixing the digester, (3) improved dewaterability of digestate and (4) sanitised product.

The following pre-treatments may be considered :

* [[Particle filtering]]
* [[Sizing]] (e.g. chipping, grinding)
* Thermal pre-treatment

== Process and technologies ==
=== Process ===
There are three basic anaerobic digestion processes, namely psychrophilic, mesophilic, and thermophilic, which take place over different temperature ranges. Psychrophilic digestion is a low temperature (<20°C) process. Mesophilic digestion takes place between 20 and 45°C, which can take a month or two to complete, and thermophilic digestion between 45 and 65°C, which is faster, but its micro-organisms are more sensitive. The majority of the agricultural biogas plants are operated at mesophilic temperatures. Thermophilic temperatures are applied mainly in large-scale centralised biogas plants with co-digestion<ref>{{Cite web|year=2021|title=Anaerobic digestion|e-pub date=2021|date accessed=6/9/2021|url=https://www.eubia.org/cms/wiki-biomass/anaerobic-digestion/}}</ref>. The process of anaerobic digestion takes place through four successive stages: hydrolysis, fermentation, acetogenesis, and methanogenesis.<ref>{{Cite journal|author=Junye Wang|year=2014|title=Decentralized biogas technology of anaerobic digestion and farm ecosystem: opportunities and challenges|journal=Fronties in Energy Research|volume=2|page=|doi=10.3389/fenrg.2014.00010}}</ref> In the hydrolysis step, the feedstock is broken down into soluble substrates (e.g., sugar and amino acids) by enzymes. Fermentation involves the conversion of sugar, amino acids, and fatty acids into ammonia, organic acids, hydrogen (H2) and CO2. In the acetogenesis step, volatile fatty acids are broken down into acetic acids, CO2 and H2. Finally, methanogenesis step converts acetate, formaldeyde, and H2 to CH4 and water<ref>{{Cite journal|author=Jay N. Meegoda, Brian Li, Kush Patel, Lily B. Wang|year=2018|title=A review of the Processes, Parameters, and Optimization of Anaerobic Digestion|journal=International Journal of Environmental Research and Public Health|volume=15|page=|doi=10.3390/ijerph15102224}}</ref>.
[[File:Anaerobic stages.png|thumb|Simplified scheme of pathways in anaerobic digestion (not own work)]]

Usually, the produced biogas must be dried and drained for condense water and biological or chemical cleaned for H2S, NH3 and trace elements. Further upgrading of the biogas to increase the CH4 content could be realized by membrane separation of CO2 and pressurising the biogas.
== Product ==
Anaerobic digestion produces two valuable outputs, namely biogas and digestate. Biogas is composed of methane (CH4), which is the primary component of natural gas, at a relatively high percentage (50 to 75%), carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and trace amounts of other gases. The energy in biogas can be used like natural gas to provide heat, generate electricity, and power cooling systems. Biogas can also be purified by removing the inert or low-value constituents (CO2, water, H2S, etc.) to generate renewable natural gas (RNG). This can be sold and injected into the natural gas distribution system, compressed and used as vehicle fuel, or processed further to generate alternative transportation fuel or other advanced biochemicals and bioproducts.

The digestate can be used in many beneficial applications provided that is is appropriately treated post processing. This could be in form of animal bedding, nutreint-rich fertilizer, organic-rich compost, or as soil amendment.

=== Post-treatment ===
The remaining digestate can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.

Anaerobic digestion

2022-01-31T15:15:34Z

Stef Denayer: /* Dranco */

{{Infobox technology}}
<onlyinclude>'''Anaerobic digestion''' is a process through which micro-organisms break down organic matter, such as animal manure, wastewater biosolids, and food wastes, in the absence of oxygen. Anaerobic digestion intended for biogas production takes place in a sealed tank (called an anaerobic digester), which is designed and constructed in various shapes and sizes specific to the site and feedstock conditions. These sealed vessels contain complex microbial communities that break down the waste and produce biogas and digestate (i.e., the solid and liquid material end-products of the process). The biogas can be used as a source of energy. The remaining digestate can be used as a fertiliser, or it can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.</onlyinclude>

== Feedstock ==
=== Origin and composition ===
Multiple organic materials can be combined in one digester, a practice called co-digestion. Co-digested materials include, amongst others, manure, food waste, energy crops, crop residues, and fats, oils, and greases (FOG) from restaurant grease traps.

=== Pre-treatment ===
Biomass is first separated from impurities as stones and glass. An agitator provides a good mixing between different biomass types to avoid strong changes in composition. The feed is a stirrable mixture and the dry matter content may be a maximum of 15-20% of the slurry. Co-substrates are often reduced in size by shredding before they are fed in order to make the contact surface of the biomass as large as possible.

For residual flows from the food industry, crop residues and manure, thermal and chemical pre-treatments are mainly applied. The most important effects of thermal pre-treatment are: reducing particle size, increasing solubility and improve the biodegradability. Additional advantages of thermal pre-treatment are: (1) higher loading of the digester is possible, (2) lower viscosity of the treated material which results in lower energy input for mixing the digester, (3) improved dewaterability of digestate and (4) sanitised product.

The following pre-treatments may be considered :

* [[Particle filtering]]
* [[Sizing]] (e.g. chipping, grinding)
* Thermal pre-treatment

== Process and technologies ==
=== Process ===
There are three basic anaerobic digestion processes, namely psychrophilic, mesophilic, and thermophilic, which take place over different temperature ranges. Psychrophilic digestion is a low temperature (<20°C) process. Mesophilic digestion takes place between 20 and 45°C, which can take a month or two to complete, and thermophilic digestion between 45 and 65°C, which is faster, but its micro-organisms are more sensitive. The majority of the agricultural biogas plants are operated at mesophilic temperatures. Thermophilic temperatures are applied mainly in large-scale centralised biogas plants with co-digestion<ref>{{Cite web|year=2021|title=Anaerobic digestion|e-pub date=2021|date accessed=6/9/2021|url=https://www.eubia.org/cms/wiki-biomass/anaerobic-digestion/}}</ref>. The process of anaerobic digestion takes place through four successive stages: hydrolysis, fermentation, acetogenesis, and methanogenesis.<ref>{{Cite journal|author=Junye Wang|year=2014|title=Decentralized biogas technology of anaerobic digestion and farm ecosystem: opportunities and challenges|journal=Fronties in Energy Research|volume=2|page=|doi=10.3389/fenrg.2014.00010}}</ref> In the hydrolysis step, the feedstock is broken down into soluble substrates (e.g., sugar and amino acids) by enzymes. Fermentation involves the conversion of sugar, amino acids, and fatty acids into ammonia, organic acids, hydrogen (H2) and CO2. In the acetogenesis step, volatile fatty acids are broken down into acetic acids, CO2 and H2. Finally, methanogenesis step converts acetate, formaldeyde, and H2 to CH4 and water<ref>{{Cite journal|author=Jay N. Meegoda, Brian Li, Kush Patel, Lily B. Wang|year=2018|title=A review of the Processes, Parameters, and Optimization of Anaerobic Digestion|journal=International Journal of Environmental Research and Public Health|volume=15|page=|doi=10.3390/ijerph15102224}}</ref>.
[[File:Anaerobic stages.png|thumb|Simplified scheme of pathways in anaerobic digestion (not own work)]]

Usually, the produced biogas must be dried and drained for condense water and biological or chemical cleaned for H2S, NH3 and trace elements. Further upgrading of the biogas to increase the CH4 content could be realized by membrane separation of CO2 and pressurising the biogas.
== Product ==
Anaerobic digestion produces two valuable outputs, namely biogas and digestate. Biogas is composed of methane (CH4), which is the primary component of natural gas, at a relatively high percentage (50 to 75%), carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and trace amounts of other gases. The energy in biogas can be used like natural gas to provide heat, generate electricity, and power cooling systems. Biogas can also be purified by removing the inert or low-value constituents (CO2, water, H2S, etc.) to generate renewable natural gas (RNG). This can be sold and injected into the natural gas distribution system, compressed and used as vehicle fuel, or processed further to generate alternative transportation fuel or other advanced biochemicals and bioproducts.

The digestate can be used in many beneficial applications provided that is is appropriately treated post processing. This could be in form of animal bedding, nutreint-rich fertilizer, organic-rich compost, or as soil amendment.

=== Post-treatment ===
The remaining digestate can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.

Anaerobic digestion

Stef Denayer: /* Technology providers */

{{Infobox technology}}
<onlyinclude>'''Anaerobic digestion''' is a process through which micro-organisms break down organic matter, such as animal manure, wastewater biosolids, and food wastes, in the absence of oxygen. Anaerobic digestion intended for biogas production takes place in a sealed tank (called an anaerobic digester), which is designed and constructed in various shapes and sizes specific to the site and feedstock conditions. These sealed vessels contain complex microbial communities that break down the waste and produce biogas and digestate (i.e., the solid and liquid material end-products of the process). The biogas can be used as a source of energy. The remaining digestate can be used as a fertiliser, or it can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.</onlyinclude>

== Feedstock ==
=== Origin and composition ===
Multiple organic materials can be combined in one digester, a practice called co-digestion. Co-digested materials include, amongst others, manure, food waste, energy crops, crop residues, and fats, oils, and greases (FOG) from restaurant grease traps.

=== Pre-treatment ===
Biomass is first separated from impurities as stones and glass. An agitator provides a good mixing between different biomass types to avoid strong changes in composition. The feed is a stirrable mixture and the dry matter content may be a maximum of 15-20% of the slurry. Co-substrates are often reduced in size by shredding before they are fed in order to make the contact surface of the biomass as large as possible.

For residual flows from the food industry, crop residues and manure, thermal and chemical pre-treatments are mainly applied. The most important effects of thermal pre-treatment are: reducing particle size, increasing solubility and improve the biodegradability. Additional advantages of thermal pre-treatment are: (1) higher loading of the digester is possible, (2) lower viscosity of the treated material which results in lower energy input for mixing the digester, (3) improved dewaterability of digestate and (4) sanitised product.

The following pre-treatments may be considered :

* [[Particle filtering]]
* [[Sizing]] (e.g. chipping, grinding)
* Thermal pre-treatment

== Process and technologies ==
=== Process ===
There are three basic anaerobic digestion processes, namely psychrophilic, mesophilic, and thermophilic, which take place over different temperature ranges. Psychrophilic digestion is a low temperature (<20°C) process. Mesophilic digestion takes place between 20 and 45°C, which can take a month or two to complete, and thermophilic digestion between 45 and 65°C, which is faster, but its micro-organisms are more sensitive. The majority of the agricultural biogas plants are operated at mesophilic temperatures. Thermophilic temperatures are applied mainly in large-scale centralised biogas plants with co-digestion<ref>{{Cite web|year=2021|title=Anaerobic digestion|e-pub date=2021|date accessed=6/9/2021|url=https://www.eubia.org/cms/wiki-biomass/anaerobic-digestion/}}</ref>. The process of anaerobic digestion takes place through four successive stages: hydrolysis, fermentation, acetogenesis, and methanogenesis.<ref>{{Cite journal|author=Junye Wang|year=2014|title=Decentralized biogas technology of anaerobic digestion and farm ecosystem: opportunities and challenges|journal=Fronties in Energy Research|volume=2|page=|doi=10.3389/fenrg.2014.00010}}</ref> In the hydrolysis step, the feedstock is broken down into soluble substrates (e.g., sugar and amino acids) by enzymes. Fermentation involves the conversion of sugar, amino acids, and fatty acids into ammonia, organic acids, hydrogen (H2) and CO2. In the acetogenesis step, volatile fatty acids are broken down into acetic acids, CO2 and H2. Finally, methanogenesis step converts acetate, formaldeyde, and H2 to CH4 and water<ref>{{Cite journal|author=Jay N. Meegoda, Brian Li, Kush Patel, Lily B. Wang|year=2018|title=A review of the Processes, Parameters, and Optimization of Anaerobic Digestion|journal=International Journal of Environmental Research and Public Health|volume=15|page=|doi=10.3390/ijerph15102224}}</ref>.
[[File:Anaerobic stages.png|thumb|Simplified scheme of pathways in anaerobic digestion (not own work)]]

Usually, the produced biogas must be dried and drained for condense water and biological or chemical cleaned for H2S, NH3 and trace elements. Further upgrading of the biogas to increase the CH4 content could be realized by membrane separation of CO2 and pressurising the biogas.
== Product ==
Anaerobic digestion produces two valuable outputs, namely biogas and digestate. Biogas is composed of methane (CH4), which is the primary component of natural gas, at a relatively high percentage (50 to 75%), carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and trace amounts of other gases. The energy in biogas can be used like natural gas to provide heat, generate electricity, and power cooling systems. Biogas can also be purified by removing the inert or low-value constituents (CO2, water, H2S, etc.) to generate renewable natural gas (RNG). This can be sold and injected into the natural gas distribution system, compressed and used as vehicle fuel, or processed further to generate alternative transportation fuel or other advanced biochemicals and bioproducts.

The digestate can be used in many beneficial applications provided that is is appropriately treated post processing. This could be in form of animal bedding, nutreint-rich fertilizer, organic-rich compost, or as soil amendment.

=== Post-treatment ===
The remaining digestate can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.

This can be sold and injected into the natural gas distribution system, compressed and used as vehicle fuel, or processed further to generate alternative transportation fuel or other advanced biochemicals and bioproducts.

The digestate can be used in many beneficial applications provided that is is appropriately treated post processing. This could be in form of animal bedding, nutreint-rich fertilizer, organic-rich compost, or as soil amendment.

Anaerobic digestion

Stef Denayer: /* Feedstock */

{{Infobox technology}}
<onlyinclude>'''Anaerobic digestion''' is a process through which micro-organisms break down organic matter, such as animal manure, wastewater biosolids, and food wastes, in the absence of oxygen. Anaerobic digestion intended for biogas production takes place in a sealed tank (called an anaerobic digester), which is designed and constructed in various shapes and sizes specific to the site and feedstock conditions. These sealed vessels contain complex microbial communities that break down the waste and produce biogas and digestate (i.e., the solid and liquid material end-products of the process). The biogas can be used as a source of energy. The remaining digestate can be used as a fertiliser, or it can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.</onlyinclude>

== Feedstock ==
=== Origin and composition ===
Multiple organic materials can be combined in one digester, a practice called co-digestion. Co-digested materials include, amongst others, manure, food waste, energy crops, crop residues, and fats, oils, and greases (FOG) from restaurant grease traps.

=== Pre-treatment ===
Biomass is first separated from impurities as stones and glass. An agitator provides a good mixing between different biomass types to avoid strong changes in composition. The feed is a stirrable mixture and the dry matter content may be a maximum of 15-20% of the slurry. Co-substrates are often reduced in size by shredding before they are fed in order to make the contact surface of the biomass as large as possible.

For residual flows from the food industry, crop residues and manure, thermal and chemical pre-treatments are mainly applied. The most important effects of thermal pre-treatment are: reducing particle size, increasing solubility and improve the biodegradability. Additional advantages of thermal pre-treatment are: (1) higher loading of the digester is possible, (2) lower viscosity of the treated material which results in lower energy input for mixing the digester, (3) improved dewaterability of digestate and (4) sanitised product.

== Process and technologies ==
=== Process ===
There are three basic anaerobic digestion processes, namely psychrophilic, mesophilic, and thermophilic, which take place over different temperature ranges. Psychrophilic digestion is a low temperature (<20°C) process. Mesophilic digestion takes place between 20 and 45°C, which can take a month or two to complete, and thermophilic digestion between 45 and 65°C, which is faster, but its micro-organisms are more sensitive. The majority of the agricultural biogas plants are operated at mesophilic temperatures. Thermophilic temperatures are applied mainly in large-scale centralised biogas plants with co-digestion<ref>{{Cite web|year=2021|title=Anaerobic digestion|e-pub date=2021|date accessed=6/9/2021|url=https://www.eubia.org/cms/wiki-biomass/anaerobic-digestion/}}</ref>. The process of anaerobic digestion takes place through four successive stages: hdyrolysis, fermentation, acetogenesis, and methanogenesis.<ref>{{Cite journal|author=Junye Wang|year=2014|title=Decentralized biogas technology of anaerobic digestion and farm ecosystem: opportunities and challenges|journal=Fronties in Energy Research|volume=2|page=|doi=10.3389/fenrg.2014.00010}}</ref> In the hydrolysis step, the feedstock is broken down into soluble substrates (e.g., sugar and amino acids) by enzymes. Fermentation involves the conversion of sugar, amino acids, and fatty acids into ammonia, organic acids, hydrogen (H2) and CO2. In the acetogenesis step, volatile fatty acids are broken down into acetic acids, CO2 and H2. Finally, methanogenesis step converts acetate, formaldeyde, and H2 to CH4 and water<ref>{{Cite journal|author=Jay N. Meegoda, Brian Li, Kush Patel, Lily B. Wang|year=2018|title=A review of the Processes, Parameters, and Optimization of Anaerobic Digestion|journal=International Journal of Environmental Research and Public Health|volume=15|page=|doi=10.3390/ijerph15102224}}</ref>.
[[File:Anaerobic stages.png|thumb|Simplified scheme of pathways in anaerobic digestion (not own work)]]

Usually, the produced biogas must be dried and drained for condense water and biological or chemical cleaned for H2S, NH3 and trace elements. Further upgrading of the biogas to increase the CH4 content could be realized by membrane separation of CO2 and pressurising the biogas.
== Product ==
Anaerobic digestion produces two valuable outputs, namely biogas and digestate. Biogas is composed of methane (CH4), which is the primary component of natural gas, at a relatively high percentage (50 to 75%), carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and trace amounts of other gases. The energy in biogas can be used like natural gas to provide heat, generate electricity, and power cooling systems. Biogas can also be purified by removing the inert or low-value constituents (CO2, water, H2S, etc.) to generate renewable natural gas (RNG). This can be sold and injected into the natural gas distribution system, compressed and used as vehicle fuel, or processed further to generate alternative transportation fuel or other advanced biochemicals and bioproducts.

Anaerobic digestion

2022-01-10T14:40:43Z

Stef Denayer: added the use of the end products

{{Infobox technology}}
<onlyinclude>'''Anaerobic digestion''' is a process through which micro-organisms break down organic matter, such as animal manure, wastewater biosolids, and food wastes, in the absence of oxygen. Anaerobic digestion intended for biogas production takes place in a sealed tank (called an anaerobic digester), which is designed and constructed in various shapes and sizes specific to the site and feedstock conditions. These sealed vessels contain complex microbial communities that break down the waste and produce biogas and digestate (i.e., the solid and liquid material end-products of the process). The biogas can be used as a source of energy. The remaining digestate can be used as a fertiliser, or it can be post-treated according to its intended use, e.g. by drying or composting to use it as a soil improvement agent.</onlyinclude>

== Feedstock ==
Multiple organic materials can be combined in one digester, a practice called co-digestion. Co-digested materials include, amongst others, manure, food waste, energy crops, crop residues, and fats, oils, and greases (FOG) from restaurant grease traps.

=== Origin and composition ===

=== Pre-treatment ===

== Process and technologies ==
=== Process ===
There are three basic anaerobic digestion processes, namely psychrophilic, mesophilic, and thermophilic, which take place over different temperature ranges. Psychrophilic digestion is a low temperature (<20°C) process. Mesophilic digestion takes place between 20 and 45°C, which can take a month or two to complete, and thermophilic digestion between 45 and 65°C, which is faster, but its micro-organisms are more sensitive. The majority of the agricultural biogas plants are operated at mesophilic temperatures. Thermophilic temperatures are applied mainly in large-scale centralised biogas plants with co-digestion<ref>{{Cite web|year=2021|title=Anaerobic digestion|e-pub date=2021|date accessed=6/9/2021|url=https://www.eubia.org/cms/wiki-biomass/anaerobic-digestion/}}</ref>. The process of anaerobic digestion takes place through four successive stages: hdyrolysis, fermentation, acetogenesis, and methanogenesis.<ref>{{Cite journal|author=Junye Wang|year=2014|title=Decentralized biogas technology of anaerobic digestion and farm ecosystem: opportunities and challenges|journal=Fronties in Energy Research|volume=2|page=|doi=10.3389/fenrg.2014.00010}}</ref> In the hydrolysis step, the feedstock is broken down into soluble substrates (e.g., sugar and amino acids) by enzymes. Fermentation involves the conversion of sugar, amino acids, and fatty acids into ammonia, organic acids, hydrogen (H2) and CO2. In the acetogenesis step, volatile fatty acids are broken down into acetic acids, CO2 and H2. Finally, methanogenesis step converts acetate, formaldeyde, and H2 to CH4 and water<ref>{{Cite journal|author=Jay N. Meegoda, Brian Li, Kush Patel, Lily B. Wang|year=2018|title=A review of the Processes, Parameters, and Optimization of Anaerobic Digestion|journal=International Journal of Environmental Research and Public Health|volume=15|page=|doi=10.3390/ijerph15102224}}</ref>.
[[File:Anaerobic stages.png|thumb|Simplified scheme of pathways in anaerobic digestion (not own work)]]

Usually, the produced biogas must be dried and drained for condense water and biological or chemical cleaned for H2S, NH3 and trace elements. Further upgrading of the biogas to increase the CH4 content could be realized by membrane separation of CO2 and pressurising the biogas.
== Product ==
Anaerobic digestion produces two valuable outputs, namely biogas and digestate. Biogas is composed of methane (CH4), which is the primary component of natural gas, at a relatively high percentage (50 to 75%), carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and trace amounts of other gases. The energy in biogas can be used like natural gas to provide heat, generate electricity, and power cooling systems. Biogas can also be purified by removing the inert or low-value constituents (CO2, water, H2S, etc.) to generate renewable natural gas (RNG). This can be sold and injected into the natural gas distribution system, compressed and used as vehicle fuel, or processed further to generate alternative transportation fuel or other advanced biochemicals and bioproducts.

The digestate can be used in many beneficial applications provided that is is appropriately treated post processing. This could be in form of animal bedding, nutreint-rich fertilizer, organic-rich compost, or as soil amendment.

Flocculation

2021-09-06T14:56:46Z

Stef Denayer: Created page with "Flocculation is used in biotechnology applications in conjunction with microfiltration to improve the efficiency of biological feeds. The addition of synthetic flocculants to..."

Flocculation is used in biotechnology applications in conjunction with microfiltration to improve the efficiency of biological feeds. The addition of synthetic flocculants to the bioreactor can increase the average particle size making microfiltration more efficient. When flocculants are not added, cakes form and accumulate causing low cell viability. Positively charged flocculants work better than negatively charged ones since the cells are generally negatively charged

==Input==
x
==Process and technologies==
In the brewing industry flocculation is a very important process in fermentation during the production of beer where cells form macroscopic flocs. These flocs cause the yeast to sediment or rise to the top of a fermentation at the end of the fermentation. Subsequently, the yeast can be collected (cropped) from the top (ale fermentation) or the bottom (lager fermentation) of the fermenter in order to be reused for the next fermentation.

Yeast flocculation is primarily determined by the calcium concentration, often in the 50-100ppm range. Calcium salts can be added to cause flocculation, or the process can be reversed by removing calcium by adding phosphate to form insolubable calcium phosphate, adding excess sulfate to form insoluble calcium sulfate, or adding EDTA to chelate the calcium ions. While it appears similar to sedimentation in colloidal dispersions, the mechanisms are different.

'''Extraction''' is a separation process consisting of the separation of a substance from a matrix. Common examples include ''liquid-liquid extraction'', and ''solid phase extraction''. The term ''washing'' may also be used to refer to an extraction in which impurities are extracted from the solvent containing the desired compound.

==Input==
Extraction can be used to separate a valuable substance from the feed stream.
==Process and technologies==
Fluid-fluid extraction has various possible implementation forms on an industrial scale. Two main categories can be distinguished:

The first category consists of mixers-remixers (mixer-settlers), where the extraction process consists of two separate steps. In the first step, the two liquids are mixed to enable substance transfer. In the second step, the two liquids are separated. The two steps can take place in separate reactors.

The second category uses columns in which the two liquids are in continuous contact with each other. Here, typically special measures are taken to increase the contact surface between the feed and extraction flow (e.g. dispersion of one liquid, use of trays or packing material, ... ).

Liquid-liquid extraction is a process that separates substances based on their chemical properties. The principle consists of bringing the contaminated feed flow into contact with a second fluid, i.e. the extraction fluid. The extraction fluid is chosen in such a way that it does not mix with the supply flow and that it dissolves the pollutant well. During the extraction process, the contamination of the supply flow will (partially) transfer to the extraction fluid, until a balance in concentration has been reached. This balance depends on the affinity the pollutant has for the extraction fluid. If several substances are present, the balance will be substance-dependent. In an additional step, the pollutant is separated from the extraction fluid so it can be reused.

Distillation

Stef Denayer: Created page with " '''Distillation''' is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. In industrial applications,..."

'''Distillation''' is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. In industrial applications, distillation is a physical separation process, not a chemical reaction.

The distillation of fermented products produces distilled beverages with a high alcohol content, or separates other fermentation products of commercial value.

==Input==
x
==Process and technologies==
An installation used for distillation, especially of distilled beverages, is a distillery. The distillation equipment itself is a still.

Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). Dry distillation may involve chemical changes such as destructive distillation or cracking and is not discussed under this article. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components.
==Output==
Distillation is an effective and traditional method of desalination.

Crystallisation and precipitation

2021-09-06T14:17:13Z

Stef Denayer:

'''Crystallisation''' is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation.

==Process and technologies==
Crystallization occurs in three major steps. The first is nucleation, the appearance of a crystalline phase from either a supercooled liquid or a supersaturated solvent. The second step is known as crystal growth, which is the increase in the size of particles and leads to a crystal state. An important feature of this step is that loose particles form layers at the crystal's surface and lodge themselves into open inconsistencies such as pores, cracks, etc.

The majority of minerals and organic molecules crystallize easily, and the resulting crystals are generally of good quality, i.e. without visible defects. However, larger biochemical particles, like proteins, are often difficult to crystallize. The ease with which molecules will crystallize strongly depends on the intensity of either atomic forces (in the case of mineral substances), intermolecular forces (organic and biochemical substances) or intramolecular forces (biochemical substances).

Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering, crystallization occurs in a crystallizer. Crystallization is therefore related to precipitation, although the result is not amorphous or disordered, but a crystal.

Chromatography

Stef Denayer:

'''Chromatography''' is a laboratory technique for the separation of a mixture and may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for later use, and is thus a form of purification. Analytical chromatography is done normally with smaller amounts of material and is for establishing the presence or measuring the relative proportions of analytes in a mixture. The two are not mutually exclusive.

==Input==
x
==Process and technologies==
The mixture is dissolved in a fluid (gas or solvent) called the ''mobile phase,'' which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the ''stationary phase'' is fixed''.'' The different constituents of the mixture have different affinities for the stationary phase. The different molecules stay longer or shorter on the stationary phase, depending on their interactions with its surface sites. So, they travel at different apparent velocities in the mobile fluid, causing them to separate. The separation is based on the differential partitioning between the mobile and the stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation.
