Worley works on Trinseo’s chemical recycling plant in Belgium


Belgium – Trinseo has awarded Worley a contract for front-end engineering and design (FEED) services for its first-of-a-kind chemical recycling plant in Belgium.

The plant will depolymerize post-consumer polystyrene waste into pure styrene using gasification technology. It’s an industrial-scale project that’s a first of its kind. Every year, the Trinseo plant will process 15 kilotons of recycled polystyrene flakes. These will be recycled into high-quality styrene and used to make new polystyrene and/or styrene derivatives, such as acrylonitrile butadiene styrene (ABS) and styrene acrylonitrile (SA) (SAN).

The thermoplastic polymers ABS and SAN are thermoplastic polymers. They’re tough and impact-resistant, making them ideal for use in car parts, medical devices, consumer electronics, and other applications.

FEED scope

Worley completed the project’s pre-FEED services in 2021. The feedstock, storage, condensation and distillation areas, utilities, and hot oil unit are all covered by the FEED scope. It also includes the project’s cost estimate.

Construction on the plant is expected to begin in late 2022.
