许多电子产品含有大量重金属,如何处理旧的电子产品,是一个非常现实的问题。在这方面,发达国家有了不少经验。上世纪80年代,日本东北大学的一名教授提出了“都市矿山”的理念,认为在大量的城市垃圾中,尤其是电子垃圾里面存在着各种各样的有价值的资源,就如同一座“矿山”。如果能够对这些资源加以开采,并进行有效的回收再利用,那么对于解决资源紧缺的问题将起到很大的作用。据日本物质材料研究机构2008年发表的数字显示,日本的“都市矿山”中,金的“储藏量”达6800吨,银6万吨。2001年,日本出台了《家用电器回收法》。根据这项法律,
Many electronic products contain a lot of heavy metals, how to deal with the old electronic products, is a very real problem. In this respect, developed countries have gained a lot of experience. In the 1980s, a professor at Northeastern University in Japan proposed the concept of “urban mine” and considered various valuable resources in a large amount of municipal waste, especially e-waste, as if A “mine ”. If these resources can be mined and effectively recycled, it will play a significant role in solving the problem of resource shortage. According to figures released by Japan’s Materials and Materials Research Institute in 2008, in Japan’s “urban mines,” gold’s “reserves” reached 6,800 tons and silver reached 60,000 tons. In 2001, Japan introduced the “Household Appliance Recycling Law.” According to this law,
