In the wake of the flagship Waste Management Directive (2012/19/EU), plastics can no longer be recycled, buried or exported without prior treatment to ensure the elimination of targeted molecules. However, the separate treatment of certain brominated plastics remains extremely difficult for regulatory, technical and financial reasons. At present, there is no environmentally-friendly solution to reuse these plastics loaded with synthetic flame retardant molecules that are likely to be polluting (BFRs). In order to promote a virtuous material recovery of this type of waste, effective decontamination techniques must be developed. The VALBREE project makes it possible to develop a technology to support and assist companies handling plastic waste containing BFRs. In particular, the consortium proposes to develop an innovation based on the action of UV radiation to the pilot demonstration stage. The functioning of this finalised prototype and its scope of action will be extended beyond the cases already studied. The project operators are working to adapt this technology to the needs and resources of industrialists in the INTERREG area. The work generated by the project enables industrialists in the cross-border region to process all types of plastic containing BFRs at reduced cost and to recycle this supply, which had not been possible until now.
