Develop and Commercialise the CreaSolv Process for WEEE Plastics

31st March 2006

In 2006 WRAP completed a project which successfully demonstrated and enhanced the Creasolv BFR extraction process.

Key findings
Identification of BFR-containing polymers by both BFR content and polymer type at WEEE dismantling facilities is technically feasible using relatively low cost, fast-acting hand-held instruments.
Separation of polymers by type at dismantling facilities adds greatly to polymer value and should be commercially viable for WEEE items over about 0.5Kg weight.

Overview

Overview

Plastics from waste electrical and electronic equipment (WEEE) that contain brominated flame retardants (BFR) remain a problematic waste stream as there is a current reliance on the export market for these materials. Furthermore to comply with the RoHS Directive the BFRs must be removed from the plastic components before they can be recycled. 

The development of this solvent based process, developed by the Fraunhofer Institute in Germany, is not yet complete particularly with respect to removing the residual solvent to commercially acceptable levels.  WRAP has now commissioned a piece of work to trial alternative solvent extraction technologies as well as looking for ways of improving the final mechanical properties of the CreaSolv product. 

The aim is then to demonstrate whether the treated plastic can be successfully used for commercial processing such as injection moulding in an economically and environmentally beneficial way.

The Final Report

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.

Results

Overall this project concludes that mechanical separation followed by a chemical process that removes brominated flame retardant additives from BFR-containing polymers is likely to be a better environmental and commercial option for treatment of WEEE plastics than landfill, incineration with energy recovery or feedstock recycling
