Zero Emissions by Forming Networks among Various Production Processes in Different Types of Industries

(1)产出-投入与转化技术数据库的建立及转化技术评价标准的提出本研究通过对8500家企业的问卷调查和访谈，得出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。还建立了从废品到原材料的实际转化技术(转化器)数据库。(2)转化技术的发展为了实现不同行业不同生产过程之间的联网，实现零排放，本工作开发了各种转化技术。例如，Yoshida Hiroyuki Yoshida：-使用亚临界水处理来进一步处理鱼类废物以非常快地获得有用资源的基础研究，Wataru Nishiji…更多关于有机废物再利用的主要比较评估：Tsutomu Imaoka--利用液化天然气的废气冷热处理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的塑料；以及lchiro Naruse--从固体废物中形成先进的资源。本地零排放网络的构建利用上述数据库和本研究开发的网络模拟器，分别提出了丰桥县(爱知县)和宫城县工厂之间的零排放网络。在宫城县，当只使用一个输出-输入数据库时，网络的连接数量为30家工厂。然而，当引入转化技术后，这一数字增加到1178人，转化技术对建设零排放网络的重要性变得显而易见。此外，还提出了在丰桥地区建立塑料产业网络的设想。网络建设前的废物量为174t/月，建成后下降到131t/月。较少

(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
