What is biomass? What can be done to obtain bioenergy using biomass?

The fuels which are plants and animal’s products, the source of these fuels is said to be bio-mass. Bio means living things and mass means the matter that is matter obtained from the living.

As the bio-mass when burned do not provide much heat and give out a lot of smoke or pollution through them, so there is a method called bio gas plant. The plant has a dome-like structure built with


bricks. Anaerobic micro-organisms that do not require oxygen decompose or break down complex compounds of the cow-dung or sewage or dead plants, slurry. It takes a few days for the decomposition process to be complete and generate gases like methane, carbon dioxide, hydrogen and hydrogen sulphide.


After the above process the formed biogas is stored in the plant in a tank and can be used through pipes.
