FLAME RETARDANT INITIATIVES UNDERWAY TO ADVANCE A CIRCULAR ECONOMY

In a circular economy, it is important to keep resources in use for as long as possible and recover them at the end of their service life, and to be reused as raw material for new products. The flame retardant industry is committed to seeking ways to advance the circularity of flame retardant chemistries.

A recently conducted pilot program shows that it is readily possible to use unique markers to represent specific flame retardants (e.g., brominated flame retardants) for rapid identification even when the brominated flame retardants are formulated into plastics. The project demonstrates that unique marker systems can be deployed to help whole value chains improve traceability and circularity of flame retardants throughout the life cycle of plastic used in consumer products.

Waste and Electronic and Electrical Equipment (WEEE) Plastics and Circularity: In December 2018, the European Commission launched the Circular Plastic Alliance with the aim of boosting the EU market for recycled plastic with an initial pledge of 10 million tonnes by 2025 and with more than 230 signatories to date. The recycle of flame retardant containing plastics can aid in reaching this important objective.

A report by SOFIES, a leading sustainability consultancy, provides a comprehensive analysis regarding WEEE plastics flows and recycling efforts in Europe. The report presents the successes and overarching challenges in making WEEE plastic streams more circular. Among the findings in the report is that the presence of brominated flame retardants (BFRs) in WEEE plastics does not reduce recycling yields more than other flame retardants in WEEE plastics.

While recently idled, the PolyStyreneLoop has been an industry effort to help demonstrate an innovative purification process to recycle polystyrene (PS) foam containing the discontinued flame retardant hexabromocyclododecane (HBCD). A solvent- based purification process separates HBCD from the PS, allowing the recycling of PS for use in new insulation materials. The bromine in the HBCD is recovered after safe destruction of HBCD. The bromine is reused to produce new polymeric flame retardants to be applied in insulation products.
