Biogas is a renewable source of energy that is generated by anaerobic degradation (breaking down of organic matter by bacteria in the absence of oxygen) of plant and animal wastes in presence of water. Biogas is composed of methane, carbon dioxide, hydrogen, and hydrogen sulphide. The advantages of Biogas are
Advantages of Biogas
- Biogas is a clean, non-polluting and cheap source of energy.
- There is direct supply of gas from the plant, therefore, there is no storage problem.
- The sludge left behind is a rich fertiliser containing bacterial biomass.
- The Ministry of Non-Conventional Energy Sources has been promoting the Biogas Pragramme in India. It has set up a number of bio gas plant across the country.
