Abstract Biogas is very essential and beneficial gas. Biogas is to be produced from raw material like vegetable waste, fruits waste by break down of organic waste in the absence of oxygen to generate methane and carbon dioxide. Biogas is a mixture of methane, carbon dioxide (CO2), H2S, and other gases. For the generation of biogas active digestion process is to be used. Energy or biofuel generation from organic waste is economical and easy. Generally in rural areas biogas is to be generated. The generation of vegetable waste is increasing day by day from every household. Vegetable waste can be used for the bio methanation process which is anaerobic digestion using biogas plant. The biogas plant is a simple technique to produce methane. The biogas is a nonconventional source called gobar gas. In rural India, the daily waste obtained from animals is still used as raw material for biogas plants called “Gobar Gas” daily. Anaerobic treatment systems are divided into 'high-rate' systems with biomass retention and 'low-rate' systems without biomass retention.
