It also found it was a better option than incineration with energy recovery, export for recycling outside the UK or feedstock recycling options.
During the research into options for mixed WEEE polymers, two new brominated flame retardant (BFR) extraction methods were trialled with the conclusion that this technology could be commercially available in four years.
WRAP plastics technology manager Paul Davidson said: There is an increasing need to respond to the issue of removing BFRs. This project is a pre-emptive move to create a workable, commercially viable solution for industry before the problem becomes acute.
The separation methods trialled are a major step forward in the area of WEEE plastic recycling. The development of a feasible treatment process will help to encourage increased recycling of WEEE polymers and divert waste from landfill.
The three phase project was commissioned by WRAP and carried out by Axion Recycling. It tried two different extraction methods known as Creasolv and Centrevap. Although Creasolv was found to be more successful at removing BFR, both prove financially viable alternatives to landfill or incineration.
WRAP has now entered into a technology sharing agreement with Fraunhofer IVV which will make the Creasolv process technology available for licence in the UK via WRAP.
