WEEE recycling test successfully comple 2007 Plastics Additives and Compoun

A full-scale trial was undertaken to assess the technical viability of treating mixed waste electrical and electronic equipment (WEEE) materials that contained high plastics content in an integrated metal smelter. The objective was to determine whether the integrated smelting process could effectively recover precious and base metals while also utilizing the plastic content as an energy source. The methodology involved treating WEEE materials within the smelter without the need for pre-separation of plastics, in compliance with the EU WEEE Directives. Results from the trial indicated that integrated metal smelters are capable of recycling WEEE materials efficiently, recovering precious metals and using two-thirds of the energy content from the plastics to replace traditional fuels. Furthermore, around one-third of the energy was converted into increased steam production, demonstrating the process's efficiency. Additionally, the findings revealed that the presence of flame-retardant plastics did not negatively impact the operational or environmental performance of the smelter, underscoring the potential for sustainable recycling of mixed WEEE materials.
