Over the past decades, China has been suffering from negative environmental impacts from distempered e-waste recycling activities. After a decade of effort, disassembly and raw materials recycling of environmentally friendly e-waste have been realized in specialized companies, in China, and law enforcement for illegal activities of e-waste recycling has also been made more and more strict. So up to now, the e-waste recycling in China should be developed toward more depth and refinement to promote industrial production of e-waste resource recovery. Waste printed circuit boards (WPCBs), which are the most complex, hazardous, and valuable components of e-waste, are selected as one typical example in this article that reviews the status of related regulations and technologies of WPCBs recycling, then optimizes, and integrates the proper approaches in existence, while the bottlenecks in the WPCBs recycling system are analyzed, and some preliminary experiments of pinch technologies are also conducted. Finally, in order to provide directional guidance for future development of WPCBs recycling, some key points in the WPCBs recycling system are proposed to point towards a future trend in the e-waste recycling industry.
在过去几十年中，中国一直深受电子废物回收活动不当带来的负面环境影响。经过十年的努力，中国专业化公司已经实现了环保电子废物的拆解和原材料回收，同时对电子废物回收非法活动的执法也越来越严格。因此，到目前为止，中国的电子废物回收应该向更深层次和精细化发展，以促进电子废物资源回收的工业生产。废印刷电路板（WPCB）是电子废物中最复杂、最危险、最有价值的组件，本文选择 WPCB 回收相关法规和技术的现状作为一个典型例子进行了综述，然后优化和整合了现有的适当方法，同时分析了 WPCB 回收系统中的瓶颈，并对夹点技术进行了初步实验。最后，为了为未来 WPCB 回收的发展提供方向指导，本文提出了 WPCB 回收系统中的一些关键点，以指向电子废物回收行业的未来趋势。
