Abstract
The main objective of the experiment is to produce biogas from kitchen waste by co-digestion with cow dung by an anaerobic fermentation process. An anaerobic floating-type digester was used for this purpose in mesospheric condition by maintaining a temperature of 32–38 °C and pH of 6.9–7.2 inside the reactor for optimum biogas production. Three types of feedstock consisting of mixture of food waste, cow dung, left out slurry of the reactor along with water in different proportions are used for biogas generation. Slurry prepared by mixing kitchen waste with water in 1:1 ratio is used as feed. The gas production is recorded for a span of 22 days. A significant yield of biogas having high methane content of about 68% was obtained. This process which involves conversion of organic food waste to biogas not only is source of energy but also caters the management of environmental pollution.
