Estimation of Prefecture Level Supply and Demand Balance of Non-Metallic Mineral in Japan

Abstract

 We constructed a model for estimating the future supply and demand balance of non-metallic mineral recycling resources at the prefectural level until FY2030. Using the model, we evaluated the waste generation control scenario. In the BaU scenario, the results showed that the supply of non-metallic mineral recycling resources exceeded the total demand of non-metallic mineral in 18 prefectures in 2030. In the waste generation control scenario, the result is that the supply-demand balance can be reduced by 11 points on average in Japan.
