Biogas production requires anaerobic digestion. This project is to create an Organic Processing Facility to create biogas which will be more cost effective, eco-friendly, cut down on landfill waste, generate a high quality renewable fuel, and reduce carbon dioxide and methane emissions. Overall by creating a biogas reactor on campus in the backyard of canteens will be beneficial. Kitchen (food) waste will be collected from two canteens of NCERC as feedstock for the reactor which works as anaerobic digester system to produce biogas energy. The anaerobic digestion of kitchen waste produces biogas, a valuable energy resource. Anaerobic digestion is a microbial process for production of biogas, which consists of primarily methane (CH4) and carbon dioxide (CO2). Biogas can be used as energy source and also for numerous purposes. But, any possible applications requires knowledge and information about the composition and quantity of constituents in the biogas produced. The continuously fed digester requires addition of sodium hydroxide (NaOH) to maintain the alkalinity and pH to 7. For this reactor, an Inoculum should be installed in batch reactors, to which inoculum of previous cow dung slurry along with the kitchen waste will be added to develop new Inoculum. A combination of these mixed inoculum will be used for biogas production at 37°C in laboratory (small scale) reactor (20L capacity). In this project, the production of biogas and methane can be done from the starch rich and sugary material. The rate of production can be determined at laboratory scale using the simple digesters.
