The paradox is clear for these contaminated waste streams: the solutions that exist cannot economically handle real-world contamination.

Sulzer is changing this story together with its partners

Our revolutionary chemical recycling technology EcoStyreneTM transforms even heavily contaminated polystyrene into virgin-quality styrene monomer, suitable for the most demanding applications - including those requiring food contact safety.

We deliver what others cannot:

Feedstock flexibility - Handle what others reject, minimizing costs.

Maximize styrene revenue - Process characteristics capable in delivering attractive project economics

Proven reliability built on commercial-scale experience and guaranteed performance.

Join us in creating a world where polystyrene never truly becomes waste - only material awaiting transformation.

Turning contamination into opportunity
