| Abstract | This two paper series describes a method to develop and evaluate innovative recycling strategies for WEEE plastics. Part A presents a SWOT analysis of a new dismantling based recycling process of plastic components and the integration in an existing post-shredder separation recycling facility. Subsequently, recycling strategies are developed and the economic potential is evaluated. Part B investigates the technical feasibility of the recycling strategies. Asa case study the dismantling of LCD TV plastic back cover housings is taken. First, the advantages and disadvantages of the new process and the main external factors based on the market for recycled plastics and the waste material input are discussed on industrial level. Subsequently, five recycling strategies are developed: Strategy (1) produces recycled granulates with the dismantling process for direct reapplication in electronic products, strategy (2) recycles plastics for the use as carrier materials for flame retardant masterbatches, strategy (3) blends the recycled plastic with post-shredder recyclates for material upgrading, strategy (4) recycles the plastics with the post-shredder process and strategy (5) thermally treats plastics. Finally, the economic evaluation shows that the special engineering plastics used for LCD TV back covers have very high virgin prices up to 5 (sic) per kg. The implementation of the new process indicates a significant potential for value recovery based on plastics that would otherwise be incinerated or downcycled. (C) 2019 Elsevier Ltd.
