Popis: | Plastic is probably the fraction of the waste of electrical and electronic equipment (WEEE) most challenging to manage and the market of recycled plastics from WEEE is limited to few cases. In this study, twenty WEEE plastic samples collected in two material recovery facilities (MRFs) from manually sorted housings and components and among some discarded devices stored in Casaccia Research Center were analysed through infrared identification and chemical-physical characterization. The analyses were carried out in order to select the suitable samples for mechanical recycling in 3D printer filaments. Eleven different polymers or blends were found in the WEEE samples and the majority of those collected in the MRFs resulted as mixtures of different plastics, although often of styrene-based nature. On the other hand, many WEEE samples showed a good similarity to the corresponding virgin polymers with a content of halogens and inorganic fillers less than 0.2 and 5 wt%, respectively. The thirteen selected WEEE plastic samples were washed, reduced to |
