Trinseo, a specialty material solutions provider and manufacturer of plastics and latex binders, has started receiving chemically recycled styrene monomer (rSM) through depolymerization, from the newly operational recycling plant built by the company’s partner, Indaver.

The plant is located in Antwerp, Belgium. It began production in August 2025 and uses polystyrene household packaging waste to recover the styrene monomer (SM).

Trinseo’s portfolio of STYRON Polystyrene resins, MAGNUM ABS resins, and TYRIL SAN resins can be manufactured with chemically recycled SM produced according to the mass balance principle. This means they are drop-in equivalents of their fossil-based counterparts, including for food contact applications.

"We are thrilled to announce that we have started to receive recycled styrene monomer from our partners, Indaver, and integrate their recycled styrene monomer into our products," said Ivan Angelov, Vice President Polymer Solutions. "This collaboration aligns with our commitment to sustainability and allows Trinseo to provide customers with even more sustainably advantaged2 solutions."

The PS, ABS and SAN made with rSM complement Trinseo’s broader portfolio of bio, dissolution, and other sustainably advantaged materials.
