The objective of this technology is to explore the efficacy of producing biogas from thermophilic anaerobic degradation of dairy wastes. A bench-scale proof-of-concept study will be conducted using a bioreactor operated semi-continuously. It will be load volatile solids and exposed to hydraulic retention time. The cumulative biogas yield and its methane content will be observed. Biogas is a cost effective source for combustion or to create fuel.
