Abstract：
Tremendous amounts of electric and electronic wastes (e-waste) are generated daily, and their indiscriminate disposal may cause serious environmental pollution. The recovery of non-metallic materials from e-waste is a strategy to not only reduce the volume of e-waste but also avoid pollutant emissions produced by indiscriminate disposal of e-waste. Pyrolysis, sub/supercritical water treatment, chemical dissolution, and physical treatment (e.g., ball milling, flotation, and electrostatic separation) are available methods to recover useable non-metallic materials (e.g., resins, fibers, and various kinds of polymers) from e-waste. The e-waste-derived materials can be used to manufacture a large variety of industrial and consumer products. In this regard, this work attempts to compile relevant knowledge on the technologies that derive utilizable materials from different classes of e-waste. Moreover, this work highlights the potential of the e-waste-derived materials for various applications. Current challenges and perspectives on e-waste upcycling to useable materials are also discussed.
摘要：
每天产生大量的电气和电子废物(电子废物)，乱处置可能造成严重的环境污染。从电子废物中回收非金属材料是一种策略，不仅可以减少电子废物的体积，而且可以避免因不分青红皂白地处置电子废物而产生的污染物排放。热解,亚/超临界水处理，化学溶解，和物理治疗(例如，球磨,浮选,和静电分离)是回收可用非金属材料的可用方法(例如，树脂,纤维，和各种聚合物)来自电子废物。电子废物衍生材料可用于制造各种各样的工业和消费品。在这方面,这篇评论试图汇编有关从不同类别的电子废物中提取可利用材料的技术的相关知识。此外，这篇评论强调了电子废物衍生材料在各种应用中的潜力。还讨论了电子垃圾向可用材料升级的当前挑战和观点。
