Food waste, animal manure and sewage sludge are the organic wastes that require appropriate disposal or treatment. Anaerobic digestion is a favorable measure to deal with food waste, animal manure and sewage sludge, since it can produce biogas that is one of the most attractive renewable energies. Biogas is mainly composed of methane and carbon dioxide. Methane gas can be used as an alternative energy for heating and electricity. This research reviews the treatment of food waste, animal manure and sewage sludge in Gyeongju. Anaerobic digestion systems with control scheme for stable product of biogas and efficient use of biogas energy are presented.
