项目摘要

In order to realize asocial system with sustainable development, it is necessary for local communities to construct inter-industries material circulatory network. In this aspect, wastes evolving from the industries are defined as unused materials. This study develops a methodology of constructing circulatory 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 materials, products and wastes, received from or emitted to each company of industries in a subject community. The second database defines conversion technologies that enable transformation of wastes into reusable materials. Based on these databases, material flows in the community are analyzed by a network simulator program.In this study, the methodology is tested on application to Toyohashi city in Aichi Prefecture. First of all, the databases of the industries, wastes treatment companies and waste conversion technologies were prepared. In order to propose one example of proper material circulatory network, the material flow, was analyzed by the Network Simulator based on following 3 steps. In this analysis, each network was evaluated in terms of amount of materials that were emitted from the region.i)Analyzing material circulatory networks among companies in the same industry.ii)Correcting the best network, and defining the I-O amounts as whole of the industry.iii)Analyzing material circulatory networks among different industries.As a results, an optimum hypothetical material circulatory network among different industries is proposed, which enable" to reduction of the amount of material emission from the region accounting to 10,899 ton of raw material, 8,666 ton of products, and 2,233 ton of wastes. Moreover, upscale method of the database is also predicted and described.

为实现可持续发展的社会体系，地方社区有必要构建产业间物资流通网络。在这方面，工业产生的废物被定义为未使用的材料。本研究发展了一种构建不同行业可重复使用材料循环网络的方法。通过工业调查建立了两类数据库。其中一个数据库显示了从一个主题社区的每个工业公司接收或排放的原材料、产品和废物的信息。第二个数据库定义了能够将废物转化为可重复使用材料的转化技术。在此基础上，利用网络仿真程序对社区内的物质流动进行了分析。本研究以爱知县丰桥市为研究对象，进行实证研究。首先，建立了行业、废物处理公司和废物转化技术数据库。为了提出一个合理的物料循环网络的实例，利用网络模拟器对物料流进行了分析，分为以下三个步骤。在这个分析中，每个网络都是根据从该地区排放的材料量进行评估的。1)分析同行业企业间的物资流通网络。ii)纠正最佳网络，并定义整个行业的I-O量。iii)分析不同行业间的物资流通网络。最后，提出了一个最优的产业间物料循环网络，该网络可使区域内的原料排放量减少10899吨，产品排放量减少8666吨，废弃物排放量减少2233吨。此外，还对数据库的升级方法进行了预测和描述。
