National Biogas and Manure Management Programme under Ministry of New and Renewable Energy
(Govt. of India)
What is Biogas
Biogas is a clean, non-polluting and low cost fuel. The gas is highly flammable
and is very useful as a fuel. Its composition is methane 55%, carbon dioxide
35%, hydrogen 7.4%, nitrogen 2.6% and water in traces. Its calorific value is
21.5 kg/ ltr.
What is Biogas Plant
It is a system which produces a gaseous product which is used for domestic
purposes it is obtained by anaerobic (in the absence of air) fermentation of
To provide clean
bio-gaseous fuel mainly for cooking purposes and also for other applications
for reducing use of LPG and other conventional fuels.
‘lifeline energy’ needs for cooking as envisaged in ‘Integrated Energy
bio-fertilizer/ organic manure to reduce use of chemical fertilizers.
drudgery of rural women, reduce pressure on forests and accentuate social
sanitation in villages by linking sanitary toilets with biogas plants.
climate Change by preventing black carbon and methane emissions.
Uses of Biogas
Cooking, Lighting and Running of Generator etc.
List of Beneficiary
Family Type Biogas Plants (3 cum) Dinabandhu model
feature of a Dinabandhu biogas plant is the fixed underground
digester chamber, constructed with a layer of bricks and an
additional layer of cement mortar forming the roof above. Connected
to the underground chamber is an inlet tank through which manure is
fed into the plant. The manure then ferments separating the slurry
from the methane gas which rises and collects at the top of the
digester tank, and is released through the gas outlet pipe. The
slurry passes into the outlet tank where it is ejected from the
plant and can be used as fertilizer on the field.
