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

The goal of this study was to characterise the anaerobic biodegradability potential of mango processing solid waste as well as its methane potential (measured as methane yield) using various mass ratios of mango peel and cow dung. Fruit and vegetable wastes are highly biodegradable wastes which represent a potential energy resource for producing biogas by biological process. A maximum methane yield of 3.581 m3 CH4 / Kg VS degraded was obtained at 8% TS and ratio of 1:10. The addition of cow dung speeded up the onset of biogas production and increased methane productivity. The reductions in volatile solids in the entire BMP test ranged from 96% to 98%. The specific gas production for mango peel was higher (5.3926 m3 biogas / Kg VS added and 5.5093 m3 biogas / Kg VS des) for the 1:10 ratio at 8% TS than for the 1:2 ratio 2.0342 m3 biogas / Kg VS added and 2.4535 m3 biogas / Kg VS des at 4% TS. As a result, when compared to other values, the specific gas production for the mango peel, co-digestion with cow dung for the 1:10 at 8% TS was higher.This result was compared to the anaerobic digestion capability of MP and cow dung on their own. The mango peel's organic waste comprises easily biodegradable organic materials, which contributed to a better biogas yield.
