Montinutra produces high value bioactive products from forest industry side streams. Our mission is to convert forest industry side streams into valuable ingredients for the cosmetics, food & beverage and chemical industries with our scalable technology. Montinutra has strong research and innovation background and a solid patent portfolio in key markets globally.


Roadmap: we are currently operating in pilot-scale. Our operation in Turku have capability and knowhow to extract high value bioactive compounds out of sawdust. Preparing to build industrial scale operation in 2023-2024 that will produce sustainable and ethical Sprucegum™ extract from sawdust. Sawmills produce millions of tons of sawdust and bark globally. Current commercial value of these side streams is low. Montinutra can add significant value by extracting high value bioactive compounds from those low value side streams. Sawdust and bark are usually incinerated in bio-power plants and the economic value add remains low, in addition to which the burning process causes greenhouse gas emissions.

TerraNova Energy is a pioneer in Hydrothermal Carbonization of sludge and biowaste. In 2010, TerraNova Energy constructed the first HTC demonstration plant in Europe, and subsequently, constructed the first commercial HTC plant worldwide in 2016. The advantage of the TerraNova ultra process is that it takes place in an aqueous environment, so that no drying of the input material is necessary. Furthermore, the TerraNova ultra units have a highly efficient recovery system, which minimizes the heat demand of the HTC process. The HTC coal contains hardly any water and, thanks to its high energy content, can be used for climate-friendly energy generation in coal-fired power plants or as a substitute for fossil fuels in cement plants or waste incineration plants.

Technology details
Name: Hydrothermal processing
Category: Conversion (Thermochemical processes and technologies)
Feedstock: Feedstocks with high moisture content. Food waste, Garden and park waste
Product: Bio-crude, syngas, hydrochar

Hydrothermal processing, also known as Hydrothermal Upgrading (HTU), is a thermochemical conversion process that is used to convert biomass into valuable products or biofuel. The process is usually performed in water at 250-374°C under pressures of 4-22 MPa. The biomass is degraded into small components in water. Based on the target products, which are bio-crude, syngas or hydrochar, the process conditions (e.g., temperature, pressure and residence time) are chosen. One of the most important advantages of hydrothermal processing is that it can use biomass with high moisture content withouth the need for pre-drying. Hydrothermal processing can be divided into three separate processes, depending on the severity of the operating conditions. These include hydrothermal carbonisation (HTC), hydrothermal liquefaction (HTL), and hydrothermal gasification (HTG).

Feedstock

Origin and composition

Feedstocks with high moisture content are particularly suitable for hydrothermal processing and include feedstocks such as anaerobic digestion digestate, manures, sewage sludge, DDGS, food waste, municipal wastes, and aquatic biomass such as micro- and macroalgae. Hydrothermal processing routes can typically feed slurries up to 30 wt.% solids.

Pre-treatment

Process and technologies

Process

A hydrothermal process is usually performed in water at 250-374°C under a pressure of 4-22 MPa. The process can also be carried out under self-generated pressure. The hydrothermal process is divided into two reaction conditions, namely subcritical and supercritical water conditions. These two conditions are determined by the critical point of water (i.e., 374°C and 22.1 MPa). Subcritical water is classified below the critical point at a 100-374°C temperature range and under sufficient pressure to remain liquid. Supercritical water occurs when the temperature is above 374°C and the pressure is above 22.1 MPa. The decomposition steps of biomass during the hydrothermal process can be summarized as follows: at approximately 100°C, the water-soluble portion of the biomass disperses into water, and hydrolysis takes place above 150°C. Meanwhile, biomass polymers (i.e., cellulose and hemicellulose) disintegrate into their monomeric chains. At approximately 300°C and 10 MPa, liquefaction occurs and bio-oil is obtained.

Technologies

  • HTC occurs at temperatures between 180°C and 250°C and pressure of 2-4 MPa. This is the mildest of the three hydrothermal processing routes. The main product of HTC is solid hydrochar.
  • HTL utilises subcritical water and occurs at temperatures between 250°C and 374°C and pressures up to 18 MPa. The main product of HTL is a liquid biocrude.
  • HTG or supercritical water gasification (SCWG) occurs at temperatures above 374°C and higher pressures beyond 20 MPa. The main product of HTG is a syngas.

Product

Depending on the technology, hydrochar, biocrude or syngas is produced. The produced gas is not the same as conventional syngas from gasification, which is comprised of hydrogen and carbon monoxide. Nevertheless, the gas is referred to as syngas but is typically high in either hydrogen or methane with carbon dioxide also present. The hydrochar can be utilised as fertilizers, adsorbents, and wastewater treatments. The intermediate biocrude can be further upgraded to liquid hydrocarbon fuels via catalytic hydrotreatment.
