Biogas
is a mixture of methane, carbon dioxide, hydrogen and hydrogen sulphide, the
major constituents being methane. Biogas is produced by anaerobic degradation
of animal and plant wastes in the presence of water. Anaerobic degradation is
to break down the organic matter by bacteria in the absence of oxygen. It is a
non-polluting, clean and low cost fuel which is very useful for rural areas.
Biogas plants used in our country are of two types; fixed dome biogas plant and
floating drum biogas plant.
