For microwave treatment electromagnetic radiation is utilised to induce thermal and non-thermal effects that drive physical, chemical or biological reactions[1]. The technology is usually utilised in food drying or to break down the structure of lignocellulosic biomass leading to the release of different substances (e.g. fermentable sugar).

Pre-treatment
Process and technologies
The breakdown of lignocellulosic biomass into its monomers and oligomers is induced via molecular collision due to dielectric polarisation[2]. 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, size) as well as local overheating through resonance (electromagnetic wave reflection and formation of standing waves) and low penetration for bulk materials [2].
The process can also be combined with chemical treatments utilising chemicals such as alkaline (to remove lignin) and acid (to remove hemicellulose) solutions, ammonia, and metal salts[1].
Product
- Fermentable sugar (e.g. for bio-alcohol production)
