EVALUATION OF GHG REDUCTION AND BUSINESS FEASIBILITY IN COLLABORATIVE WIDE-AREA TREATMENT SCENARIOS WITH OPPORTUNITY TO UPGRADE WASTE TREATMENT PLANTS - FOCUSING ON THE INTRODUCTION OF METHANE FERMENTATION FACILITIES AND COOPERATIVE TREATMENT OF RESIDUES AND OTHER MATERIALS BETWEEN WIDE-AREA BLOCKS -

Abstract

 Local communities are facing a severe financial situation due to rapid population decline and other factors. In this study, we propose a wide-area and cooperative scenario in which municipalities in a block cooperate with each other, taking the opportunity of the renewal of several waste incineration facilities and combining the functional conversion of existing treatment facilities to relay facilities and the introduction of biogas facilities, beyond the mere consolidation of conventional wide-area blocks, for the Kinokawa River Basin. The GHG reduction effect and business feasibility were evaluated. As a result of the analysis, it is important for each entity to introduce methane fermentation facilities and waste transfer stations at the waste treatment sites, and to establish a cooperative system for centralized waste treatment at waste treatment facilities with high power generation efficiency inside and outside the wide-area block. In addition, it was quantitatively shown that GHG reduction effects and business feasibility can be improved if such a cooperative system can be established.
