The plant has dome like structure built with bricks.A slurry of cow dung and water is made in mixing tank from where it is fed into the digester. The digester is a sealed chamber in which there is no oxygen. Anaerobic micro organism that do not require oxygen decompose or break down complex compounds of the cow dung slurry .It takes a few days for the decomposition process to be complete and generate gases like methane,carbon dioxide,hydrogen and hydrogen sulphide . The bio gas is stored in the drawn through pipes for use .( see in figure)

It contains up to 75% methane .
It burns without smoke.
It not release any poison gas.
It not cause any bad effect to ozone layer.
