Biogas - Transforming waste into energy


One of the greatest challenges faced by present world is the accumulation of waste. Organic waste can be used to produce biogas, which will lessen pollution, the burden of landfill and reduce the cost of waste disposal and revolutionize waste management. Many of the European countries and developed countries use organic waste optimally to produce biogas. In the present scenario, where the cooking gas has become expensive and world is facing shortage of fossil fuels, biogas can be the solution for many socio economic problems. Biogas can be used for cooking, heating and power generation. The byproduct of this process, the digestate slurry can be used as manure and is an excellent substitute for chemical fertilizers.

Anaerobic digestion is the method used in the production of biogas, in which organic waste is decomposed in the absence of oxygen by microorganisms. Biogas comprises of methane and little carbon dioxide and is a combustible gas. There are various stages in the production of this gas like hydrolysis, acidogenesis, acetogenesis, and the final stage is methanogenesis.  Through this process, harmful pathogens are destroyed and the waste is sanitized. The quality of the animal waste as a fertilizer is improved through this process and the digestate is a superb manure for plants.

Food waste, kitchen waste and animal waste can be used. Cow dung is most favorable in the production of biogas as the grass which the animal eats is converted into methane in the process of digestion. There will be no flies or bad odor as the drum used is tightly sealed and water proofed.

We have installed a small biogas plant in our premises and all the daily organic waste from our kitchen and hospital is put in this through a funnel and we get the gas through a pipe connection. I use the byproduct of this process, the liquid manure for all the vegetable and fruit plants and trees in my farm, thus avoiding the usage of harmful chemical fertilizers.

“PREVENT WASTING WASTE AND TURN IT INTO ENERGY”.  You can easily and economically install a mini biogas plant at home, this will benefit your family, the environment and the planet as a whole.
