Abstract

In the next few decades energy crisis will be faced by the world at a great extent due to diversified use of non-renewable energy (fossil fuel). Resulting, it is high time to think about alternative source of fossil fuel. In this regard, biogas a renewable and effective energy source which can be a great replacement of fossil fuel can be produced through anaerobic digestion is one of the best options for rumen digesta management which will lead to production of energy-rich biogas, reduction in GHGs emissions and effective pollution control in butchery. The study was investigated to enhance biogas production from rumen digesta by anaerobic co-digestion process at mesophilic condition. The experiment was carried out in 3000 ml batch type digester. The mixing ratio used was 1:1 for 40 days hydraulic retention time. Produced gas was measured by water replacement method. The result showed that co-digestion of rumen digesta with vegetables increased the biogas production. The maximum biogas generation from rumen digesta of chicken and goat, cow and chicken, cow and goat and co-digestion of four substrates were 93.5,1311, 36.1, and 1072 ml/day at the 14th, 13th, 24th, and 7th day respectively. The average biogas generation was found for the above samples were 3.35, 96.80, 11.09, and 137.12 ml/day respectively. The higher cumulative production of biogas was found from co-digestion of rumen digesta with vegetables. Therefore, the study is suggested that optimum co-digestion mixing ratio which produced biogas might be holds promise for the future energy crisis recovery.
