Producing Biogas
Biogas is a gas mixture that occurs when organic waste rots in oxygen-free environment (anaerobic digestion). Depending on the feedstock material, biogas is 50-70 % methane with excellent fuel properties. One cubic meter of methane is equivalent to one liter of diesel fuel, and requires about 7 kg of biowaste, for example. The rest of the gas mixture is mainly carbon dioxide.
