豊島廃棄物等処理事業における環境性・経済性の評価

抄録

In this Study, we have taken data about Teshima waste treatment project over thirteen years. In this paper, we put focus on Teshima waste treatment project economic and environmental by using LCA (Life Cycle Assessments) and LCC (Life Cycle Cost). Usually, LCA is a tool to measure the environmental load in the life cycle from production or construction to use, service, disposal or removal. In this study we focus on use and service. We found the environmental impact of intermediate treatment facility (melting facility) occupied the greatest load among the whole processes. Moreover, during the attempt to complete the project within the deadline decided by the prefecture, we can see the trend of environmental impact increase due to digging process and waste transportation process towards completion of removal. Comparing the Teshima waste treatment project with the general waste disposal facilities, we found that the load of the Teshima waste treatment project is extremely large both in terms of economic and environmental impact.
