Abstract
This study conducted a case study for Shimukappu village, where the waste management system depends on only landfilling after abolition of the incineration facility. The first objectives of this study was to investigate composition of the landfilled waste and to propose short - term strategies for landfill waste reduction. The second one was to evaluate scenarios other than landfilling scenario from a long-term standpoint. The third one was consideration of a case where a large amount of waste generation from resort area was eliminated. As a result, thorough source separation of recyclables as well as measures against bulky waste should be conducted for life extension of the existing landfill site. From a long-term stand point, intermediate treatment processes, such as incineration or production of refuse derived fuel (RDF), will need smaller costs than only landfilling. But, comparinsom of costs only after introduction of intermediate treatment prolesses from 2031 fiscal year showed that improvement of source separation would be less expensive even if landfilling scenario was continued. In addition, elimination of waste collection and treatment from the resort area can reduce costs by about 50%.
