Abstract:
In recent years the interest in bio-fuels has been increasing, motivated in the one side by
the need for reducing green house gas emissions and on the other side by the desire to
improve energy security by reducing our dependence on imported fossil fuels. Biogas is a
resultant combustible gaseous fuel produced by anaerobic fermentation of organic material
by the action of microorganisms. Biogas is a valuable source of renewable energy in many
senses. It is low cost, low in emissions, decentralized and has socio economic strength
especially in rural areas. The only gas of economic value that is produced in an anaerobic
digester is methane. It is naturally flammable, odorless, burns cleanly and can be used as a
fuel.
