项目摘要

(1) Construction of Database of Output-Input and Conversion Technologies, and Proposal of Criterion for Evaluation of Conversion Technology A survey based on questionnaires for 8500 factories and interviews on how materials move as various productive processes go on was conducted and basic input-output and output-input database needed for the establishment of zero-emission network were obtained in this work. Database on actual conversion technologies (converter) from waste products to raw materials was also made. Moreover, the criterion for evaluation of such conversion technology was proposed.(2) Development of Conversion Technology In order to attain zero emission through networking among various production processes in different types of industries, various conversion technologies were developed in this work. For example, Hiroyuki Yoshida : - a fundamental study on further treatment of fish waste to obtain useful resources very fast using sub-critical water treatment, Wataru Nishiji … More ma - comparison evaluation of the reuse of organic wastes, Tsutomu Imaoka - the local zero emission system of the organic solid wastes using waste cool heat from LNG, Kiyohiko Nakasaki - production of biodegradable plastic from sludge, and lchiro Naruse - the formation of advanced resources from solid wastes. Above researches are almost completed.(3) Construction of a local zero emission network The zero emission networks between the factories in Toyohashi area (Aichi Prefecture) and Miyagi Prefecture were proposed respectively using the database mentioned above and the network simulator developed by this research. In Miyagi Prefecture, when only an output-input database was used, the number of connection of the network were 30 factories. However, when conversion technologies were introduced, the number increased to 1178, and it became clear how conversion technology is important for construction of a zero emission network. Moreover, the network in plastics industry was proposed in the Toyohashi area. The amount of waste before network construction was 174 t/month but after construction of the network, it decrease to 131t/month. Less

(1)产出-投入和转化技术数据库的构建及转化技术评价标准的建议本研究通过对8500家工厂进行问卷调查和访谈，了解了各种生产过程中物料的流动情况，获得了建立零排放网络所需的基本投入-产出和产出-投入数据库。还建立了关于从废物到原材料的实际转化技术（转化器）的数据库。并提出了评价这种转化技术的标准。(2)转换技术的开发为了通过不同类型产业的各种生产过程之间的联网实现零排放，在这项工作中开发了各种转换技术。例如，Hiroyuki Yoshida：-一项利用亚临界水处理进一步处理鱼废物以快速获得有用资源的基础研究，Wataru Nishiji ...更多信息 ma -有机废物再利用的比较评估，Tsutomu Imaoka -利用液化天然气废冷热的有机固体废物的本地零排放系统，Kiyohiko Nakasaki -从污泥中生产可生物降解塑料，以及lchiro Naruse -从固体废物中形成先进资源。上述研究已基本完成。(3)利用上述数据库和本研究开发的网络模拟器，分别提出了丰桥地区（爱知县）和宫城县工厂之间的零排放网络。在宫城县，当仅使用输出-输入数据库时，网络的连接数量为30个工厂。然而，当引入转换技术时，数量增加到1 178个，转换技术对于零排放网络的建设非常重要。此外，在丰桥地区提出了塑料工业网络。管网建设前的垃圾量为174吨/月，但管网建设后，垃圾量下降到131吨/月。少
