PS loop

an innovative purification process to recycle polystyrene foam demolition waste containing HBCD

Operation PS Loop B.V.

JUNE 12, 2023 UNIQUE RECYCLING SOLUTION FOR EPS INSULATION MATERIALS LAUNCHED The first industrial plant for recycling EPS insulation materials goes into regular operation this summer: the innovative CreaSolv® Technology enables PSLoop to recycle HBCD-containing polystyrene foams on an industrial scale and testifies to the industry’s great innovative strength. After the German EPS Converters (GEC)…

(RE)Launch PS Loop B.V.

JUNE 22, 2022 Restart of the Polystyrene Loop initiative – the closed loop recycling of EPS insulation materials The demonstration plant for the industrial recycling of EPS insulation materials from demolition and refurbishment work is reopened exactly one year after it was put into operation for the first time. A consortium of German companies has…

Bankruptcy Polystyrene Loop B.V.

Terneuzen (NL), March 8th 2022 Unfortunately, Polystyrene Loop B.V. fell into bankruptcy on March 8th, 2022. The Polystyrene Loop cooperative was a combined EPS and Brominated Flame retardant industry effort to build and operate a novel demonstration plant aiming to recycle deconstruction EPS waste with destruction of the flame retardant HBCD, and subsequent recovery of…


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.

The PolyStyreneLoop recycling project

PolyStyreneLoop contributes to the Circular Economy by recycling polystyrene (PS) foam demolition waste containing HBCD.


The PS Loop plant is located in Terneuzen, the Netherlands. The physical recycling process currently allows Terneuzen to recycle 3,000 tons of HBCD-containing material in 2024. The HBCD is removed in a solvent-based purification process. It is then treated the bromine recovery unit, owned and run by our partner ICL. The maximum expansion stage is 8,000 tons per year. This reduces CO₂ emissions by up to 50 percent and protects the environment and climate.


A Solvent-based Purification process

•PS Loop is a solvent-based Purification process, allowing the separation of  polystyrene from legislated HBCD. HBCD is further treated in the Bromine Recovery Unit from ICL.
•The compacted PS-foam demolition waste is dissolved in tanks containing a PS-specific liquid. Left over solid impurities after pretreatment (dirt, cement and the like) are separated through filtration and then incinerated.
•Then another liquid is added, which transforms the PS into a gel, while the additive (HBCD) stays in the remaining liquid. The PS gel is then separated from the process liquids.
•Once cleaned, this gel is transferred into granulated polymer. The liquid and used additives are distilled and can be used in theclosed PS Loop. The HBCD remain in the sludge, which is then treated in the Bromine Recovery Unit (BRU) by ICL.
