However, reliable operation and maintenance services are needed to ensure long-term and sustainable use of the system. The co- digestion of food waste and fresh cow dung proved to be suitable with feed size of 2.5 cm. The process was successfully demonstrated by using temperature controlled system to maintain thermophilic conditions in batch mode. The resulting successful production of biogas was used for heating purpose such as cooking. The nutrient content of the effluent slurry indicated its potential use as a fertilizer in the botanical garden of campus. This would certainly contribute to waste minimization and a truly Green Campus and a Zero Waste College.
