Recycling of flame-retarded plastics from waste electric and electronic equipment (WEEE)
Martin Schlummer, Andreas Mäurer, Thomas Leitner and Walter Spruzina 

Shredder residues produced in plants processing waste electric and electronic equipment are excluded from material recycling due to a variety of polymeric materials and the presence of brominated flame retardants (BFR), which might contain banned polybrominated diphenyl ethers or toxic polybrominated dioxins and furans   (PBDD/F). Herein we present a technological approach to transfer a significant portion of the shredder residue into recycled polymers. The technological approach   consists of a density-based enrichment of styrenics, which are subjected to a solvolysis process (CreaSolv® process) in a second stage.

Materials Recovery from Mobile Phones by the CreaSolv® process
Dr. Andreas Mäurer and Martin Schlummer - Fraunhofer-Institut für Verfahrenstechnik und Verpackung, Freising and Dr. Gerald G. Altnau - CreaCycle GmbH, Grevenbroich.

The European WEEE directive prescribes recycling quotas of 65% and a 75% recovery for mobile phones. This forces recyclers of post-consumer electronic equipment to find economical and ecological feasible waste management approaches. This paper proposes the CreaSolv® process as a waste treatment option, which bases on the dissolution of the polymeric housing materials, separates the single components and thus allows the production of an ABS/PC polymer recyclate as well as the recovery of a metal rich fraction suitable for metal recovery.

Good as new - Recycling plastics from WEEE and packaging wastes

by Andreas Mäurer and Martin Schlummer

Waste electrical and electronic equipment often contains huge quantities of plastics. An innovative process offers an exciting solution to the problem of recycling them. This solvent-based process purifies polymers contaminated with brominated flame retardants or other additives, and produces ure recycled polymers also from other plastic waste streams including expanded polystyrene.
