1 前言 21世纪是注重环境的世纪,“与地球环境的共存”是人类面临的重要课题之一。随着废弃物的不断增加,导致了废弃物处理场的严重不足,由酸雨产生的环境有害物质的溢流以及焚烧时产生的二噁英弥散等与人类生活息息相关的问题,因此研究废弃物的减少和回收(利用)系统等解决对策已成为当务之急。在日本国内,正在扩大包装容器再循环法的施行,制定并修正“省能法”和“废扫法”,施行家电回收法等环境关连法。在废扫法中,从TV大型基板上回收金属正在成为应尽的义务,现在已经出现了许多关于PCB回收方法,本文就松下电器产业(株)开发的PCB回收系统加以叙
1 Foreword The 21st century is an environment-oriented century. “Coexistence with the Earth’s Environment” is one of the major issues facing mankind. With the continuous increase of waste, which leads to the serious shortage of waste disposal sites, the overflow of environmental harmful substances caused by acid rain and the dioxin dispersion caused by incineration and other issues that are closely related to human life. Therefore, Reducing and recycling (using) systems and other solutions has become a top priority. In Japan, the implementation of the recycling law for packaging containers is being expanded, and the “Energy Conservation Law” and the “Waste Sweep Act” are formulated and amended to implement environmental laws such as the Appliance Recycling Law. In the waste scavenging method, the recovery of metal from large-scale TV substrate is becoming a duty, and now there have been many PCB recycling methods, this paper Matsushita Electric Industrial Co., Ltd. PCB recovery system to be Syria
