Over the past 30 years, China has been suffering from negative environmental impacts from distempered waste electrical and electronic equipments (WEEE) recycling activities. For the purpose of environmental protection and resource reusing, China made a great effort to improve WEEE recycling. This article reviews progresses of three major fields in the development of China's WEEE recycling industry: legal system, formal recycling system, and advanced integrated process. Related laws concerning electronic waste (e-waste) management and renewable resource recycling are analyzed from aspects of improvements and loopholes. The outcomes and challenges for existing formal recycling systems are also discussed. The advantage and deficiency related to advanced integrated recycling processes for typical e-wastes are evaluated respectively. Finally, in order to achieve high disposal rates of WEEE, high-quantify separation of different materials in WEEE and high added value final products produced by separated materials from WEEE, an idea of integrated WEEE recycling system is proposed to point future development of WEEE recycling industry.
在过去的 30 年中,中国一直受到废弃电子电气设备(WEEE)回收活动带来的负面环境影响。为了保护环境和资源再利用,中国大力改善 WEEE 回收。本文综述了中国 WEEE 回收产业发展的三大领域的进展:法律体系、正规回收系统和先进的综合工艺。从改进和漏洞两个方面分析了与电子废物(e-waste)管理和可再生资源回收有关的相关法律。还讨论了现有正规回收系统的成果和挑战。分别评估了典型电子废物先进综合回收工艺的优势和缺陷。最后,为了实现 WEEE 的高处置率、WEEE 中不同材料的高定量分离以及由 WEEE 分离材料产生的高附加值最终产品,提出了综合 WEEE 回收系统的理念,以指出 WEEE 回收产业的未来发展方向。
