Milestone reached to reduce post-consumer styrenic waste: first production of virgin polystyrene from only depolymerized material

A lab-scale quantity of general-purpose polystyrene produced from 100% recycled styrene monomer by INEOS Styrolution in Antwerp is claimed to signal a game-changer in polystyrene production. The material is the result of experimental polystyrene production runs with styrene monomer feed-stock produced from depolymerization of styrenic plastic. The tests – conducted in cooperation with commercial partners and universities – resulted in the production of virgin material with the same product properties as polystyrene produced from new styrene monomers.

“We are very excited having achieved this breakthrough,” commented Michiel Verswyvel, global R&D expert. “Due to its relatively clean decomposition into its building blocks, polystyrene is almost designed to be recycled. Within our global project team we are working to make this a stable process on a commercial level, by learning for example more about purity requirements of the feedstock material.”

“I am convinced that we have achieved a significant milestone in proving that polystyrene is recyclable and contributes to reducing post-consumer waste,” added Rob Buntinx, president EMEA. “We are now looking forward to scaling the process to an industrial level and saving valuable resources.”
