Methodology to Construct Material Circulation Network in a Local Community

Abstract

In order to realize a social system with sustainable development, it is necessary for local communities to construct inter-industries material circulation network. In this aspect, wastes evolving from the industries are defined as unused materials. This study suggests a methodology of constructing networks among different industries for reusable materials. Two types of databases are made by means of industrial surveys. One of the databases reveals information about raw material, products and wastes, which is received or emitted on each company of industries in a subject community. The second database defines conversion technologies that enable to transform the wastes into reusable materials. Based on the databases, a network simulator program can analyze material flows in the community. In this paper, Higashi-Mikawa area in Aichi Prefecture was chosen as a model of local community, and the databases of the industries and wastes treatment companies were made, furthermore the material flow for. selected wastes were simulated. Additionally, one suggestion about optimum material circulation network in an application of proper conversion technology is hypothetically designed.
