Biogas is a mixture of 56% methane gas (CH4), 40% carbon dioxide (C02) and rest, a mixture of H2, H2S and N2. It is produced by digestion, Pyrolysis and hydro gasification in a specific plant called as Biogas Plant. Biogas plants are of various types like — Janata biogas plant, Dean Bandhu biogas plant, Khadi and Village Industries Corporation (KVIC) type biogas plant, Pragati Design biogas plant and Chinese biogas plant.
The dry weight of organic matter produced by plants, their derivatives and wastes are called as BIOMASS. The biomass includes crop residues, plant parts, body parts of dead animals and animal wastes. As biomass is created due to photosynthesis by plants, so energy from biomass or bio wastes is regarded as another form of solar energy.

We have damaged ecosystems in the name of development. Wildlife too is facing danger. Our activities have impacted in such ways that animal population has fallen into a serious zone of danger.
New Technologies are developed for improving and increasing industrial production. Similarly, new projects are formulated for providing energy to those industries.
Human activities of pollution are modifying the natural process of green house effect. The advent of the Industrial Revolution in the 1700s boosted up the activities of burning of fossil fuels like coal, oil and natural gas which released lots of heat absorbing gases into the atmosphere.
