How is Bio-CNG Actually Produced?

Biogas is produced by fermenting biomass by different microorganisms which decomposes the organic components of biomass (e.g. sludge, organic residues and waste materials, etc.) under exclusion of oxygen. Initially, the methane (CH4) content of biogas is only about 50%. To use it as a fuel, it is purified to almost 100% methane. The resulting bio-methane is subsequently compressed to high pressure. It is then known as bio-CNG (compressed natural gas), whose quality is similar to that of fossil natural gas. This is how biogas is converted into a fuel.
Refined biogas, known as bio-methane or Renewable Natural Gas (RNG), contains approximately 98% methane. It can serve as a supply of green gas for homes and businesses or as bio fuel to power cars, buses and commercial vehicle fleets
