- How biogas is produced?
- Types of Biogas plant?
Biogas is produced by the anaerobic digestion or fermentation of biodegradable materials such as biomass , manure, sewage, municipal waste, green waste, plant material, and crops. Vegetation: when vegetation decomposes, It gives off Methane gas.
- Biogas comprises primarily methane (CH4) and carbon dioxide (CO2) and may have small amounts of hydrogen sulphide (H2S), moisture
- The composition of biogas varies depending upon the origin of the anaerobic digestion process.
- Landfill gas typically has methane concentrations around 50 %.
- Advanced waste treatment technologies can produce biogas with 55â€“75 % methane.
