EPS Recycling Plants by EPC - even for toxic HBCD containing EPS

21.11.2016

EPC's recycling plants for expanded polystyrene (EPS) are not only highly efficient, but also offer a profitable and environmentally friendly recycling for different PS (polystyrene) and EPS waste.

EPC's recycling plants for expanded polystyrene (EPS) are not only highly efficient, but also offer a profitable and environmentally friendly recycling for different PS (polystyrene) and EPS waste. The process was developed in collaboration with the renowned Fraunhofer Institute (IVV Freising) and CreaCycle GmbH. The resulting CreaSolv® Technology produces a high-purity PS Recyclate as a final product from PS and EPS waste. Various precisely coordinated cleansing steps, the use of selected CreaSolv® formulations and specially tailored separation and filtration steps efficiently remove a wide range of contaminants.

This also includes EPS additives such as HBCD (Hexabromocyclododecane), which can be depleted below the permissible limits. The final product is a high purity and odorless PS granulates. Compared to conventional mechanical recycling processes, which cannot extract toxic and hazardous substances contained in polystyrene, EPC’s EPS recycling plants based on the CreaSolv® Technology produce high purity polystyrene. This process also offers great ecological advantages over waste disposal methods used to date for EPS / PS waste.

EPS is not only a common packaging material, but has been used as an insulating material for more than 50 years e.g. it has been installed on over 80% of exterior walls in Germany. Till 2015 this sort of EPS insulation was equipped with HBCD, a substance of which production and use are now banned worldwide. HBCD is placed on the so-called POP list (persistent organic pollutant) and wastes that contain this substance have to be destroyed residue-free, which means that in the future, mechanical recycling is no longer possible and only the chargeable waste incineration remains. For waste incineration plants, however, EPS, with its high calorific value, is a challenge and can only be combusted together with other waste in low concentrations.
