What is biomass? What can be done to obtain bio-energy using biomass?
Biomass is organic matter which is made from living organisms like plants and animals. Biomass is used to fuel the electric generators. The energy from the living organisms is obtained from the direct or indirect means. When biomass is burned to create heat is a direct method and conversion into biofuel is an indirect method.
Various are the methods to obtain bio-energy using biomass:-
1. Plants and animals produce or we plant trees and obtain wood (fire- wood) these all are used as a fuel for a very long time.
2. Cow- dung cakes can be used as a heating source or as a fuel.
3. Residue of the plant materials like vegetable waste, sewage or cow- dung cakes are first decomposed in the absence of oxygen to make bio- gas or from cow- dung is known as ‘gobar- gas’.
4. Bio- gas is used in the gas engines to convert this energy into electrical energy and heat.
