For microwave (MW) treatment electromagnetic radiation is used to induce thermal and non-thermal effects that drive physical, chemical or biological reactions[1]. As a rapid and effective heating source with both thermal and non-thermal effects, MW can directly interact with the material, thereby accelerating chemical, physical, and biologic reactions.[2] Microwave treatment causes a rise in the temperature within a penetrated medium as a result of rapid changes of the electromagnetic field at high frequency.[3] The technology is usually applied in food drying or to break down the structure of lignocellulosic biowaste leading to the release of different substances, such as fermentable sugars.
Feedstock
Origin and composition
Microwave irradiation has been successfully used in the pretreatment of several biowaste streams, including agricultural residues, woody biomass, grass, energy plants, and industrial residuals.[4]
Pre-treatment
Process and technologies
The breakdown of lignocellulosic biomass into its monomers and oligomers is induced via molecular collision due to dielectric polarisation[5]. Compared to other thermal treatments, the technology brings several advantages, such as reduced plant footprint, higher throughput, higher reaction rates, as well as higher yield and purity[1]. However, a disadvantage is the unequal distribution of the applied microwave power through non-homogeneous material (such as differences in composition, geometry, or size) as well as local overheating through resonance (electromagnetic wave reflection and formation of standing waves) and low penetration for bulk materials [5].
The process can also be combined with chemicals such as alkaline (to remove lignin), acid (to remove hemicellulose), ammonia, and metal salts[1].
Product
- Fermentable sugar (e.g. for bio-alcohol production)
