The disposal of cow dung was a great problem in dairy as the dung raises a lot of problems for human health and ecology system. Fossil fuels are depleting day by day there was need to increase the use of renewable energy sources and for reduce the dependency on fossil fuels for our energy needs. At Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, University dairy produces a huge amount of dung everyday which had a problem of disposal of such waste. To handle the waste in an efficient manner large scale modified fixed dome biogas had been constructed. A 50 m3 fixed dome biogas plant had been constructed to produce biogas. An average percentage of Nitrogen, Phosphorus and Potassium were found 1.13, 0.75, 0.55 and 1.33, 0.90, 0.68 in fresh cow dung and digested slurry, respectively. The biogas production from modified Janta biogas plant was found maximum 49.90 m3day-1 on 29th May 2021 at 49.90 oC digester temperature and minimum of 40.00 m3day-1 on 17th December 2021 at 33.10 oC digester temperature. Economic indicators i.e. net present worth, benefit-cost ratio, payback period and internal rate of return of the system was found to be Rs. 2143000.40, 1.87, 2 years, 11 months & 3 days and 40 % respectively.
