This document discusses Bio-CNG (biodegradable compressed natural gas), which is produced from biogas through additional processing. Biogas is produced from biomass and contains primarily methane and carbon dioxide. To produce Bio-CNG, the biogas undergoes biological desulphurization to remove hydrogen sulfide, followed by upgrading using water scrubbers or pressure swing adsorption to increase the methane content. The methane-rich gas is then compressed to high pressures between 20-25 MPa and stored for use. Bio-CNG has advantages over fossil fuels as it is renewable, has a high calorific value suitable for vehicles, and produces lower greenhouse gas emissions. However, producing Bio-CNG also faces
