Biogas is a gas produced as a byproduct of microbial decomposition of biomass in the absence of air. It consists mainly of methane (45-70%) and carbon dioxide (55-30%) but also contains some impurities like hydrogen sulfide and water vapor, which are removed in a gas conditioning unit. Due to its properties, biogas is close to natural gas (80-98% methane). It also has no color or smell and is lighter than air.
Biogas can be used for burning in boilers and internal combustion engines without enrichment. Most often, biogas is used to generate electric power.
