In a Circular Economy we want to keep resources in use for as long as possible and recover them at the end of their service life to be re-used as raw material for new products. In a circular economy, growth is decoupled from finite resources and should be beneficial for people, environment and economics at the same time.

closing the loop

PolyStyreneLoop contributes to the Circular Economy by recycling polystyrene (PS) foam demolition waste containing the legislated flame retardant hexabromocyclododecane (HBCD). The Solvent- based Purification (SBP) process developed by CreaCycle GmbH and Fraunhofer IVV separates HBCD from the PS allowing the recycling of PS to be used for new insulation materials. The bromine in the HBCD is recovered by the Bromine Recovery Unit (BRU) of ICL after safe destruction of HBCD. The bromine is re-used to produce new polymeric flame retardants to be applied in insulation products made from the recyclate Loop-PS.

life cycle assessment

A life cycle assessment (LCA) was conducted by TüV Rheinland to assess how PolyStyreneLoop compares to incineration. The study showed that the carbon foot print is almost halved when choosing PolyStyreneLoop. For every ton PS-foam treated by PolyStyreneLoop the equivalent to 3 ton CO2 are saved.


partnering for progress

PolyStyreneLoop demonstrates how the PS-foam value chain meets the fundamental requirements of a circular economy, by ensuring a technically, economically and environmentally sustainable closed-loop recycling system.

loop ps recyclate

PolyStyreneLoop produces Loop-PS recyclate which is sold to members and supporters who then use it as feedstock to produce new insulation products.

Loop-PS is used to produce new insulation PS-foam products and contributes to saving energy in buildings.

Solution for XPS with (H)CFCs

XPS produced before 2002 contains CFCs and (H)CFCs as blowing agents, making this waste a hazardous waste. PolyStyreneLoop works on a pre-treatment for this waste stream allowing the safe release and capture of the (H)CFCs. Afterwards the XPS plates can undergo the CreaSolv® Process to separate the HBCD from the PS.
