Production of biogas from mesophilic anaerobic digestion of kitchen waste.

The study focuses on production of biogas as an alternative energy by using biodegradable wastes (BWs) in view of solving waste management at household level. The research was conducted in Laboratory (IEM department), Khulna University of Engineering and Technology (KUET) in 2012.Biogas refers to a gas made from anaerobic digestion of any type of household waste. While any organic material may be a feedstock for anaerobic digestion, waste organic matter represents a vast potential for sustainable energy production. Food waste in particular is a relatively where daily a large amount of kitchen waste is obtained which can be utilized for better purposes. Project was 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 emission. Overall by creating a biogas reactor on campus in the backyard of our halls will be beneficial. Kitchen (food waste) was collected from different halls of KUET as feedstock for our reactor which works as anaerobic digester system to produce biogas energy. The anaerobic digestion of kitchen waste produces biogas, a valuable energy source and about the composition and quantity of constituents in the biogas produced. If biogas technology were adopted throughout the food service industry, this would significantly advance campus and societal sustainability.
