This two paper series describes a method to develop and evaluate new recycling strategies for WEEE plastics. Part A presents a SWOT analysis that leads to five recycling strategies for the optimal integration of new dismantling based recycling processes for plastic components in an established post-shredder separation infrastructure. In this paper the technical feasibility of the strategies is demonstrated by means of LCD TV back cover housings. The component recycling is shown to produce recycled PC/ABS with phosphorous flame retardants suitable for direct re-application in electronic products. The high quality is characterized by good mechanical and aesthetical properties as well as a recovered flammability. HIPS with brominated flame retardants was recycled to produce masterbatches. The technical feasibility of this strategy was proven by mechanical and flammability testing. However, the presence of deca-BDE requires this material to be incinerated. A combination of EU legislation research and forecasting shows that the origin of this flame retardant are TV models produced before 2008 and restricted concentrations still need to be expected for decades to come. Further, a blending strategy of HIPS/PPE is shown to improve the mechanical properties of post-shredder recycled HIPS. The evaluation of refeeding ABS/PMMA into the post-shredder recycling process of ABS indicates only partial compatibility. Further, complications due to density differences make this strategy more suitable for polymers that are already commercially recycled such as ABS and HIPS. Colour is identified as a key requirement that limits the use of WEEE plastics in high-quality products.
