Over the last decades the electronics industry and ICT Industry in particular has revolutionized the world: electrical and electronic products have become ubiquitous in today's life around the planet. After use, those products are discarded, sometimes after re-use cycles in countries different from those where they were initially sold; becoming what is commonly called e-waste. Compared to other traditional waste streams, e-waste handling poses unique and complex challenges. e-Waste is usually regarded as a waste problem, which can cause environmental damage and severe human health consequences if not safely managed. e-Waste contains significant amounts of toxic and environmentally sensitive materials and is, thus, extremely hazardous to humans and the environment if not properly disposed of or recycled. On the other hand, e-waste is often seen as a potential source of income for individuals and entrepreneurs who aim to recover the valuable materials (metals in particular) contained in discarded equipment. Recently, for a growing number of people, in developing countries in particular, recycling and separation of e-waste has become their main source of income. In most cases, this is done informally, with no or hardly any health and safety standards, exposing workers and the surrounding neighborhoods to extensive health dangers as well as leading to substantial environmental pollution. Treatment processes of e-waste aim to remove the hazardous components and recover as much reusable material (e.g. metals, glass and plastics) as possible; achieving both objectives is most desired. The paper discuss societal implications of proper e-waste management and key elements to be considered in the policy design at country level.
在过去几十年里,电子行业,尤其是信息通信技术行业彻底改变了世界:电气和电子产品在当今全球生活中已无处不在。使用后,这些产品会被丢弃,有时是在与最初销售国不同的国家经过再利用周期之后;从而成为通常所说的电子垃圾。与其他传统废物流相比,电子垃圾处理带来了独特而复杂的挑战。电子垃圾通常被视为一个废物问题,如果管理不当,可能会造成环境破坏并对人类健康产生严重后果。电子垃圾含有大量有毒和对环境敏感的材料,因此,如果处理或回收不当,对人类和环境危害极大。另一方面,电子垃圾往往被视为个人和企业家的潜在收入来源,他们旨在回收废弃设备中所含的有价值材料(特别是金属)。最近,对于越来越多的人,尤其是发展中国家的人来说,电子垃圾的回收和分离已成为他们的主要收入来源。在大多数情况下,这是在没有或几乎没有任何健康和安全标准的情况下非正式进行的,使工人和周边社区面临广泛的健康风险,同时也导致严重的环境污染。电子垃圾处理过程旨在去除有害成分,并尽可能多地回收可再利用材料(如金属、玻璃和塑料);最理想的是能同时实现这两个目标。本文讨论了妥善管理电子垃圾的社会影响以及国家层面政策设计中应考虑的关键要素。
