Abstract
The purpose of this study is to identify factors that affect waste reduction through evaluating municipal solid wastes management (MSWM) activities on the basis of the survey results on community participation. Therefore, two different types of questionnaire covering all municipalities throughout Japan were carried out with a view to ascertaining the current MSWM practices as well as the state of the art of community participation in around MSWM projects. An attempt was made to identify the linkages between MSWM projects and waste reduction on the basis of the survey data, and then an analysis using the quantification method Ⅱ was carried out to see the extent to which various types of community participation activities contribute to waste reduction. As a result, the study has found that those community activities that promote zero-emission and ISO14001-based EMS certification are identified as factors affecting waste reduction.
