ESTIMATION OF NATIONAL OUTCOMES FROM CONSOLIDATING MUNICIPAL WASTE INCINERATORS: DEVELOPMENT OF CONSOLIDATING ALGORITHM AND ITS APPLICATION

Abstract

 In order to adapt declining population and severe municipal financial status, consolidation of municipal waste facilities draws policy attention again in Japan. This study developed a consolidation algorithm of waste incinerators at national level and applied it with three consolidation scenarios to estimate national outcomes of the incinerator consolidation. As results, the consolidation up to year of 2030, when population in Japan will decrease, was needed to retain the capacities of incinerators at the present level. If we plan to enlarge the capacities of incinerators, large consolidation beyond 300 tonne/day was necessary; however, chances in up-coming 10 years were small. The results also showed that lifetime extension of incinerators was justified if policy aims at assuring the incinerator capacity in the 2030s.
