In the field of energy, the term biomass stands for the organic matter of vegetal or animal origin that is used to gain energy thanks to different kind of processes, such as: biochemical (e.g.: anaerobic digestion) or thermo-chemical (e.g.: combustion, gasification or pyrolysis).
Choosing the energy conversion process is linked to the chemical and physical properties of the biomass; in particular, it relates to the C/N ratio, which occurs between the content of carbon (C) and nitrogen (N), as well moisture content.
The arising great interest revolves around the biomasses and it is justified by the multiple applications in which this class of compounds is involved.
- Energy production (Biopower);
- Biofuels production (bioethanol, biogas and biodiesel);
- Synthesis of products (syngas, pyrolysis oil)
