Estimation of Potential Emissions of Plastic Waste and Analysis of Regional Factors in Japanese Municipalities

Abstract

In 2019, the Japanese government formulated the "Plastic Resource Circulation Strategy" and set multiple targets related to emissions reduction and recycling. To effectively set policies to achieve these goals, it is necessary to clarify the actual situation of plastic waste emissions. However, in Japan, there has not been sufficient research on the amount of plastic waste generated at the regional level. In this study, We estimated the potential emissions of plastic waste for all municipalities in Japan based on the composition survey results of incineration facilities, and analyzed the regional factors that influence per capita emissions. As a result, a relationship was found between the expenditure on processed foods (snacks, prepared foods, beverages) and the value added in the accommodation and food service industry, and it was suggested that the overall emissions may be larger than previous estimations.
