ABSTRACT
In Japan, a large quantity of waste flows among cities and regions as can be seen from Figure 6.1 for the 2001 interregional waste shipments among Japanese regions. This figure shows that the industrial waste especially concentrates in the north part of the Kyusyu region and in the west part of the Tohoku region. In recent years, some waste has also been shipped to China through individual nego-tiations under the Basel treaty. What are the fundamental structural elements of the waste flow? How do we model the interregional and/or international physical distribution of waste flow? These questions are very important for regional natural resource management, global warming, and environmental and health risk management. Our motivation is to research the answers to these questions. 2001 interregional shipments of industrial waste. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203805855/7b638d06-aa1c-4eff-9e71-9515d50be89b/content/fig6_1_B.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> Source: Ministry of the Environment of Japan.
