Develop a process to separate brominated flame retardants from WEEE polymers

Final Report

Abstarct

This final report summarises the practical trials and process design work conducted during a three phase project funded by WRAP to develop a process to separate brominated flame retardants (BFRs) from waste electrical and electronic equipment (WEEE) polymers.
The work shows that the modified Creasolv1 process for extraction of brominated flame retardants from WEEE polymers has potential to be commercially viable in the UK context at a throughput of 10,000te/year. The Creasolv process was originally developed by Fraunhofer IVV in Germany and has been modified further in the course of this project in collaboration with Fraunhofer IVV.
The Creasolv process will remove most BFR types from styrenic WEEE polymers. Work done for this project has shown that styrenic polymers constitute over half of collectable WEEE polymers and that they contain the great majority of the BFRs found in WEEE thermoplastics. It is has not been tested with the newer BFR types such as brominated epoxy oligomers because these are not yet found in significant quantities in real WEEE….Read more Sans titre 2
