废弃电气和电子设备是一种复杂的废物流，适用于一种废物类别或产品的处理办法可能不适用于其他废物类别或产品。对德国拆解中心处理的富含塑料的碎片进行了全面的案例研究。来自电视、显示器、打印机和小型家用电器的塑料已被广泛表征。根据表征结果，结合最先进的处理技术，为每种输入馏分设计了优化的回收和升级工艺。采用连续密度分离法生产符合欧洲有害物质限制指令（RoHS）的电视机外壳高抗冲聚苯乙烯，产率约为60%。有价值的丙烯腈-丁二烯-苯乙烯/聚碳酸酯可以通过近红外分选从显示器和打印机外壳中提取。聚烯烃和/或混合苯乙烯类的无卤素部分可以通过密度分离从显示器、打印机和小型家用电器中分选出来。新兴的分离技术进行了讨论，以提高回收的结果。
Waste electrical and electronic equipment is a complex waste stream and treatment options that work for one waste category or product may not be appropriate for others. A comprehensive case study has been performed for plastic-rich fractions that are treated in German dismantling centres. Plastics from TVs, monitors and printers and small household appliances have been characterised extensively. Based on the characterisation results, state-of-the-art treatment technologies have been combined to design an optimised recycling and upgrade process for each input fraction. High-impact polystyrene from TV casings that complies with the European directive on the restriction of hazardous substances (RoHS) was produced by applying continuous density separation with yields of about 60%. Valuable acrylonitrile butadiene styrene/polycarbonate can be extracted from monitor and printer casings by near-infrared-based sorting. Polyolefins and/or a halogen-free fraction of mixed styrenics can be sorted out by density separation from monitors and printers and small household appliances. Emerging separation technologies are discussed to improve recycling results.
