बायोगॅस संयंत्र ( Biogas plant ) :- In a biogas plant , animal dung , wet garbage is decomposed by anaerobic microbes . This produces methane gas and carbon dioxide gas and it is called biogas . Biogas contain about 55% to 60% methane and the rest is a carbon dioxide .It is cheap fuel and meets the demand for cooking gas . It is also used in the production of electricity .
