Biogas as an energy source, many people would never consider this as a viable & renewable energy source.
Biogas can be used in many different ways. Cooking, Heating, Lighting, and powering generators and turbines those are all choices to use this source of energy.
Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas consist of Methane (CH4) & Carbon Dioxide(CO2).
Biogas as a fuel is used for any heating purpose, such as cooking. It is also used to convert it into electricity and heat. Other uses are as fuels for cars and machinery. The use of biogas can help farmers to drive down their input cost by generating their own energy.
Biogas is a clean and renewable form of energy which produces less greenhouse gases than conventional energy sources (coal,oil).
Any organic material is suitable to make biogas, Killing two birds in one, it can assist in the disposal of agricultural waste and organic materials in landfills naturally produce biogas, which can be tapped..
The remaining liquid organic waste (which is left after the production of Biogas) can be used as a fertiliser for crops, which makes the cycle continue and repeat itself.
So who thought that cow manure, rotting plants and landfills can be used to generate energy.
