Abstract

Worldwide every year 41.8 billion tons of electrical and electronic equipment (EEE) reaches the end-of-life with changing designs, product, and material compositions. In order to enable the recycling industry to adapt its processes to the evolutions in product design and material composition, it is crucial to assess these changes in waste streams. Therefore, a scheme is presented that helps to evaluate the quality of plastics in WEEE for mechanical recycling. Based on a case study for computer housings, laptop back covers, and tablet housings, the scheme is applied and discussed regarding their potential quality for a disassembly-based recycling process. For this assessment Fourier transform infrared (FTIR) spectroscopy is used to determine the plastic types and degradation found in this waste stream. The discarded desktop computer and tablet housings consist of different plastics, such as ABS, PC/ABS, HIPS, and ABS/PMMA, whereas laptop housings are largely dominated by PC/ABS.
