Methanisation is a natural biological process of degradation of an organic material by micro-organisms in the absence of oxygen. This process requires a raw material: biomass. At the end of the methanisation process, two products are generated: biogas (methane + carbonic gas) and a residue, called digestate.
Biomethanisation consists of reproducing this process on an industrial scale. The resulting biogas is purified, i.e. concentrated to more than 90% methane. Once the purification has taken place, the biogas is then called biomethane.
This biogas can be converted into different useful forms of energy. There are three lines of reuse:
✓ Electricity production
✓ Thermal energy production (hot air, hot water)
✓ Biofuel (biomethane) production
