Industrial-Scale E-Waste/WPCB Recycling Lines
This chapter introduces industrial-scale state-of-the-art e-waste/WPCB recycling plant applications in the world. Simple WPCB recycling flowsheet adapts physical recycling methods to recover Cu, fiber, and resin powder. Today, integration of electronic component disassembly, solder removal, fine pulverization, dry gravity, and electrostatic separation to obtain Cu-rich mixed powder and glass fiber+resin powder are very important in most of the current plants (with 1.0–1.5 t h−1 e-waste processing capacity) in the world. Umicore’s integrated smelter-refinery has the biggest e-waste recycling capacity. MGG, Elden, Daimler Benz, NEC, Dowa, Sepro, Shanghai Xinjinqiao, SwissRTec, WEEE Metallica, Hellatron, Aurubis, Attero, Noranda, Rönnskar, and Taiwan e-waste/WPCB recycling practices, aims, capacities, and application flowsheets are presented and discussed in detail. It seems that pyrometallurgical treatment methods are most widely used than hydrometallurgical methods in the world. But, aqueous recovery methods for e-waste recycling are gaining more importance. Lastly, academic and industrial research and practices for e-waste recycling are compared.
