Welcome to Polystyreneloop
With our innovative recycling process we aim to set up an industry scale recycling process for HBCDD containing PS foams.
The PolyStyreneLoop Foundation is a non-profit organisation under Dutch law, focussing on the operational implementation of a circular economy. The Foundation's key project is to build and to operate a large-scale demonstration plant that provides a sustainable, closed-loop route for the recycling of polystyrene (PS) insulation foam waste and for the recovery of bromine. The demonstration plant is intended be built in Terneuzen next to the ICL-IP facilities, and will work with a physical polymer dissolution process using the CreaSolv® Technology. The removed HBCD will be destructed in the bromine recovery unit at ICL-IP Terneuzen (see BRU photo facilities) and converted back into bromine.
PS Foam waste
Polystyrene foam boards have been widely used for building insulation in Europe since the 1960s. As the service life of these boards ranges from 30 to 100 years, the construction industry expects a significant increase of PS foam waste from demolition. These large quantities represent quite a challenge for the recycling industry. Another issue is the presence of HBCDD in many existing PS foam boards. HBCDD is a brominated flame-retardant which was commonly used to ensure the safety of buildings and their inhabitants.
Because of its persistence in the environment, HBCDD is now listed as a substance of very high concern (SVHC) under the EU REACH Regulation, and as a persistent organic pollutant (POP) under the UNEP Stockholm Convention.
To date, incineration ensuring the destruction of HBCDD is the only allowed treatment for materials containing this substance. The dissolution process that will be used in the PolyStyreneLoop demonstration plant is combined with a bromine recovery unit and offers an alternative, a safe and a sustainable end-of-life treatment for PS Foam waste.
