Biogas is a mixture of different gases formed by anaeorbic decomposition of organic matter. It is a source of renewable energy which can be produced from various raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste.
Biogas basically contains methane (CH4), and carbon dioxide (CO2). Typical compounds that may be also found in biogas are hydrogen sulfide (H2S), moisture and Volatile Methyl Siloxanes (VMS).
The energy carrier in biogas is methane (CH4) and its amount depends on the origin of the anaerobic digestion process. Landfill gas typically has methane concentrations around 50%. Advanced waste treatment technologies can produce biogas with 55%–75% methane.
Biogas as an energy source is utilised by Combined Heat and Power (CHP) generation in biogas engines or by upgrading it to biomethane which can be pumped into a gas grid. However before turning it into electricity or heat source it must be properly conditioned to prevent the installation deterioration and harm to the people and the environment caused by hazardous compounds incorporated in biogas.
