Proper initiatives regarding the energy consumption, the reduction of disposed solid and wastewater by e-waste recycling, etc. can reduce the environmental impact. Taking into account the aspects regarding the waste separation into individual polymers, the majority polystyrene fraction of WEEE can be recycled by melt compounding as elastomer modified compounds. The method can bring significant economic and technical advantages with obtaining performance composites. The 10% share of waste printed circuit boards (WPCB) from WEEE can be also recycled, but the high content of epoxy or phenolic thermosetting resins makes it difficult to be used in a conventional melt processing method. Presently, the profitability is due to the metals and glass fiber recovery. Hence, several proposed applications of non-metallic WPCB have been comprehensively examined. One method includes its use as filler in thermoplastic composites. The research was focused on processing by extrusion and injection molding some compositions containing WEEE. The amount of waste was selected based on the processability and mechanical properties of WEEE based compounds with different percent of the polystyrene fraction and WPCB, respectively, obtained by melt compounding. The characteristics were tested after modifying the polystyrene fraction of WEEE with styrene-butadiene block-copolymer. For waste printed circuit boards, recycled polypropylene was used as continuous phase.enMelt processingRecyclingThermoplastic compositesWEEEconference poster
