Abstract

Biogas is an alternative and eco-friendly renewable power source and biogas effluent is used as a bio-fertilizer. In this research, the kinetic of biogas formation was studied and also the acceptance of biogas effluent as a bio-fertilizer was evaluated. 8000 g of cow dung and 600 ml of inoculum were fed to the digester. The volume of biogas production was observed for 50 days by using Orsat Apparatus and gas chromatography was used to analyze the gas. From the data, it was found that the formation of methane gas didn’t depend upon the concentration of cow-dung hydrocarbon and it followed the mechanism of the zero-order reaction. On the other hand, the elementary analysis of biogas effluent by AAS ensured the property of effluent as a bio-fertilizer. Utilization of Miscanthus fuscus with E. coli and S. aureus ensured a higher degree of biodegradation.
