废旧手机处理现状

一、背景:

据有关数据显示,目前中国的手机用户已逾10亿,按平均每部手机的使用寿命3年、重量100g来算,每年我国将产生6000吨的废旧手机.

一方面,废旧手机量在激增,另一方面手机材料中金属材料和高分子材料极难自然降解,散落于环境中将长期存在并造成巨大污染。虽然威胁巨大,但合理的回收和有效的利用则可以使废旧手机成为最好的"都市稀有金属矿"。以金为例,废旧手机中含金250g/t,而南非最丰金矿含金量也不过3-10g/t。从环境保护和资源回收角度来看,对废旧手机正规回收予以无害化处理是非常必要的,不仅会产生巨大的环境效益和经济效益,在很大程度上将关系到人类和社会的可持续发展。因此,如何合理回收利用废旧手机,避免环境污染和资源浪费,已成为世界各国关注与研究的热点。然而我国的废旧手机回收现状却令人担忧。整体看来我国废旧手机的回收率不足1%,回收利用率很低,没有将这种"资源"合理的利用起来。

The volume of waste mobile phones increases dramatically. The metal materials and polymer materials in mobiles are extremely difficult to natural degradation. If they are scattered in the environment, it will cause long-term pollution. There is a big potential threat, but there is also a huge opportunity as the waste mobile phone can become the best "rare metals mine in the urban" if they can be recycled properly and effectively. Taking gold as an example, the gold content of scrap mobile phones is 250 g/t, and the gold content of the richest gold mine in South Africa's is only 3-10 g/t. From the angles of environmental protection and resource recovery, the standard and harmless waste mobiles recycling processing is highly necessary, as it not only produce huge economic and environmental benefits, but also related to the sustainable development of human society. Therefore, the question of how to proper recycle waste mobile phones, avoid environmental pollution and resource waste, has attracted worldwide attention and become a popular research topic. However, the current scrap mobile phones recycling situation in our country is quite worrying. The overall recycling rate is less than 1% of used mobile phones in our country. The recycling rate is very low, we have not fully exploited the use of this "resource".

二、废旧手机的危害性与资源性:

废旧手机主要由塑料外壳、锂电池、线路板、显示器等几大部分组成。这些部件中含有铅、镉、汞等有毒有害物质,随意抛弃将会严重污染土壤和地下水,对人类的身体健康构成巨大的威胁。
