Biogas is a mixture of methane and carbon dioxide produced by bacterial
degradation of organic matter and used as a fuel. Biogas typically refers to
a (biofuel) gas produced by the anaerobic digestion or fermentation of
organic matter including manure, sewage sludge, municipal solid waste,
biodegradable waste or any other biodegradable feedstock, under anaerobic
conditions. Biogas is comprised primarily of methane and carbon dioxide.
If biogas is cleaned up sufficiently, biogas has the same characteristics as natural gas. In this instance the producer of the biogas can utilize the local gas distribution networks. The gas must be very clean to reach pipeline quality. In this form the gas can be now used in any application that natural gas is used for. Such applications include distribution via the natural gas grid, electricity production, space heating, water heating and process heating. If compressed, it can replace compressed natural gas for use in vehicles, where it can fuel an internal combustion engine or fuel cells.
Gober gas is a biogas generated out of cow dung. In India, gober gas is generated at the countless number of micro plants (an estimated more than 2 million) attached to households.
