Abstract: In 21st century, sustainable development has a colossal and crucial role to play in global environmental apprehensions such as GHG emission from fossil fuel combustion, damage to the environment by the haphazard disposal of waste. Under these current circumstances, biogas production technology has flourished and has proved to be a meritorious success story today. Biogas is produced by microbial anaerobic digestion of organic wastes such as animal waste, plant material, sewage crops etc. Biogas principally comprises of 50% -60% of methane and 25%-45% of CO2. In the recent past, research on this technology has been limited to some extent due to the complex phenomenon existed with various factors and parameters influencing it.
