EVALUATION SYSTEM OF CO₂ EMISSION REDUCTION BY IMPLEMENTING INTEGRATED METHANE FERMENTATION SYSTEM AS A MUNICIPAL ORGANIC WASTE RECYCLING SCHEME IN TOKYO BAY REGION

Abstract

This paper focuses on the evaluation of CO₂ emission reductions that can be achieved by implementing integrated methane fermentation systems in sewage treatment plants (STPs) as a municipal organic waste recycling scheme in Tokyo Bay Region. Target organic wastes are sewage/sanitary sludge (simplified as sewage sludge in the following article due to the insignificant quantity of sanitary sludge in STPs), food wastes from household, food distribution and manufacturing sector, livestock excreta and agriculture waste. Geographical Information System (GIS) is utilized to develop a database platform which provides spatial and attribute data on the flow of organic waste matters. Two cases designed for evaluations are differentiated by the types of organic wastes and different organic wastes collecting boundaries.
