Abstract

The world's fuel supply is under jeopardy due to the approaching scarcity of petroleum. With the help of biogenous methane, humanity may successfully combat this menace; but, the world has yet to completely use this technology because its practitioners have so far ignored a basic premise of science, namely that the output of work is dependent on the energy available to do that task.
Bio Gas obtained from organic and solid waste is sometimes also known as swamp or landfill gas. It has a pungent stench and may easily be identified as a component in the air near regions where naturally occurring organic degradation is occurring. Biogas is created when organic matter decomposes in an environment with little or no oxygen. This naturally occurring bacterial decomposition usually occurs underground or in regions where gas displacement limits access to oxygen.
The good thing about Biogas is that it is a natural process that can be used with almost any organic waste (Crop waste, lawn clippings, septic tank waste and even your household trash). Although energy is not free, the conversion process may be regulated and improved to boost efficiency, which in turn lowers the cost of the process.
Appropriate Rural Technology Institute (Pune) has created a small biogas plant that uses discarded food as a feedstock rather than dung or manure to provide biogas for cooking. The plant is compact enough to be utilized by urban homesand many household in urban and rural areas have been installed these plants.
This is demonstrated by the existing practice of employing low-calorie inputs in biogas plants, such as cow dung, distillery sewage, municipal solid waste, or sewerage, which condenses methane generation inefficient. Dr. Anand Karve (Trustee of ARTI) formed a portable biogas system that employs starchy or sweet feedstock in 2003 to correct this biased approach. Only 2 kg of such feedstock yields around 1/2 kg of methane, and the process takes around a day to complete.
Traditional biogas systems, which employ bovine dung, sewerage, and other waste, require roughly 35-40 kg of feedstock to produce the same amount of methane and take about 5-6weeks to complete. Thus, the system created by is around 20 times more efficient compared to conventional system in terms of converting feedstock into methane, and it is 40 times as efficient in terms of reaction time. As a result, the new system is highly efficient than the conventional biogas system.
