Bio-energy is a renewable energy resources like solar energy resources, wind energy resources, but it differs from hydro energy and thermal energy resources. The collection and controlling of bio-wastes and producing fertilizer from this waste for using irrigation showing it is friendly with nature. Collecting food waste from houses, mess halls, hostels, hotels etc., and it will digest to produce the bio-gas. Anaerobic digester is micro-bacterial technique .They are in three steps. The main content of bio-gas is methane and carbon-di-oxide .By using bio-gas, we can reduce the emission of carbon- di - oxide and methane .Adding super –di-oxide to bio-gas will produce an alkaline product which is used in laboratories.In my opinion Best materiel available in kaerala or Rubber producing states or county is waste water after the production of rubber sheets.
The production of bio-gas is from the degradation of organic materials .The collecting of organic wastes such as pig manure, dairy manure , cow dung, food waste, crop etc. and they will mechanically compress and degraded .The landfill gas is a bio-gas which can produce from the degradation of wet organic materials done by the anaerobic digesters .
In India Goober gas is produced in bio-gas plants because it is very useful and friendly to the environment .The cow – dung’s and kitchen waste are collected in a digests tank which is placed in the ground through a pipe. The waste digested by the digestive bacteria extract carbon – di-oxide and methane contents from it. The produced bio-gas is stored in a tank and the remaining waste water is collected in another tank for further use. The usages of fossil, forest many and also the air and water pollution can be reduced by using the bio-gas. It improves the lifestyle of rural people and solves the problems of producing electrical energy .Goober gas is the main bio gas used in India which is produced from goober- dung’s. So, tools required for the construction of bio-gas plant is less.
