  5. 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 55–75 % methane.
