Characterization of Mesophilic Biodigestion of Cow Dung and Mango Peel in Relation to Bioenergy Batch Study

The purpose of this study was to determine the anaerobic biodegradability potential of mango processing solid waste as well as its methane potential (measured as methane yield) using different mass ratios of mango peel and cow dung. Fruit and vegetable wastes are highly biodegradable wastes that could be used to generate biogas through a biological process. At 8% TS and a ratio of 1:10, a maximum methane yield of 3.581 m3 CH4 / Kg VS degraded was obtained. The inclusion of cow Dung accelerated biogas production and increased methane productivity. The reductions in volatile solids ranged from 96 to 98 percent across the entire BMP test. The specific gas production for mango peel was higher for the 1:10 ratio at 8% TS (5.3926 m3 biogas / Kg VS added and 5.5093 m3 biogas / Kg VS des) than for the 1:2 ratio at 4% TS (2.3422 m3 biogas / Kg VS added and 2.4535 m3 biogas / Kg VS des). As a result, when compared to other values, the mango peel’s specific gas production, The codigestion with cow dung for the 1:10 at 8% TS was greater. This result was compared to the ability of MP and cow dung to digest anaerobically on their own. The organic waste from mango peels is composed of easily biodegradable organic materials, which contributed to a higher biogas yield.
