摘要
综述了发达国家电子废弃物的规范化回收体系和集约化处理处置体系,剖析了发展中国家电子废弃物资源化过程中存在的主要问题和环境污染后果,并就目前国内对电子垃圾的无序回收管理和以损害环境为代价的原始粗放型处理方式进行了分析和讨论。
This paper intends to make a research review over the advancements made so far on the recycling, re-use treatment, and disposal system used for WEEE in some developed countries along with our analysis of the hardnuts in the current research work in this way in our country and some other developing countries, such as India and Pakistan. The used or waste electrical and electronic equipments （WEEE, e-waste, or devices and appliances） has become one of the fastest growing trends among all the solid wastes around the world with the development of the IT industry. In view of the environmental pollution and human health hazards brought about by WEEE and the high residual value of the materials left-over in them, such as precious metals, alloys, plastics and glass, more and more people began to realize the potential value hidden in such used or waste appliances, which attract ever-growing attention in recent years. However, it is just a beginning. Actually more and more untouched areas are awaiting the promising efforts of the researchers. To address potential environmental problems that have resulted from the improper management of WEEE even in some developed countries and organizations, who have already drafted national legislation laws and plans for improved recycling, re-use and valuable material recovery of the WEEE in hoping to reduce the amount and types of e-waste. Untbrtunately, such a kind of large-scale and official campaign and governmental or nation-wide recycling and re-use plans and laws haven＇t yet been started. The scale and method of WEEE recycling in China remains low-graded and primitive, which have resulted in serious consequences in environmental pollution and contamination. Therefore, from the point of view of the recycling, treatment, and disposal system of such e-wastes, what has to be done can be divided into two categories. One is to be based on the resource reuse and the environmental protection, and the other is to be based on the recycling of valuable materials. Recently, China has begun to take measures to cope with this problem. The legal issues concerning WEEE recycling has also been brought about to the national issues for general public concern. And, last of all, the paper has also given detailed discussion on the issues worthy of further attention.
