This paper sheds light on the increase in generation of non-metallic mineral wastes and the decrease in demand for construction by investigating the material flow resulting from and the economic influence of changes in the supply and demand for wastes, focusing on the period from the near future to 2030. We predict the amount of final disposal of n...

As a prerequisite to fully consider the socioeconomic situation in one country at a certain time and to implement appropriate environmental policies there, methodology and analysis models need to be established to quantitatively measure the environmental burden generated by human activities. This chapter outlines the use of input-output models for...

In line with recent trends toward decentralization, prefectural and municipal governments in Japan are becoming increasingly involved with managing global warming in their regions. As a result, there is a new need to estimate the environmental effects of regional economic activities, which can be used to establish effective energy policies at the r...

Since non-metarilc mineral waste such as concrete mass, asphalt concrete mass, sand, slag and coal ash occupies 36% of total amount of waste generation and 26% of total amount of final disposal, it has significant influence on material flow of our country. Although the amount of non-metaril mineral wastes produced is expected to increase in the nea...

We constructed a multi-region waste input-output (WIO) table for the 47 prefectures in Japan using a multi-region IO table of goods and services (Hasegawa et al., 2011) and interregional waste-shipment data provided by the Ministry of the Environment of Japan (2006, 2008). Internal disparities in are a crucial issue in most countries, particularly...
