Anaerobic digestion technology has been used since many decades. It is known to be an established technology for biogas generation from various organic matters like cow dung, kitchen waste, fruit waste and municipal wastes. The present work explores the analysis of biogas generation in single & double digester biogas plant with baffles by using Pongamia Pinnata seed cake as a feed material. The biogas yield has been studied in single & double digester biogas plant with baffles for a period of 30 days. The yield of biogas in a single & double digester biogas plant with baffles has been recorded on daily basis by feeding 0.5 kg and 1.0 kg of Pongamia Pinnata seed cake. From the experimental results, the average volume of biogas generated is calculated and observed that, in modified double digester biogas plant with baffles, the biogas generated is 57% more than that of single digester biogas plant.
