ACTUAL SITUATIONS OF PROBLEMS AND MEASURES ON LIFE-PROLONGATION AND CLIMATE CHANGES IN LANDFILL SITES

Abstract

 In recent years, life-prolonged landfill sites may cause problems such as aging facilities and changes in leachate quality. On the other hand, life-prolonged landfill sites might be affected by future climate change. In particular, the internal storage and overflow of leachate from landfill sites due to heavy rain are concerned. Therefore, this study conducted a questionnaire survey on landfill sites nationwide in oder to understand actual situations of the above-mentioned problems systematically. As a result, the actual situations on problems related to life-prolongation, leachate management, such as internal storage and changes in leachate quality, and disaster response. In conclusion, it is necessary to consider the planned implementation of inspections and repair for landfill sites toward the life prolongation and climate change. In particular, this study suggested the necessity of redesigning the leachate treatment facility scale and treatment processes.
