- Recycled styrene monomer produced via depolymerisation now delivered at scale
- Enables high-quality styrenics, including for food-grade and medical applications
- Adds chemically recycled material to our portfolio alongside mechanically recycled and bio-attributed products
FRANKFURT, Germany, Sept. 25, 2025 /PRNewswire/ — The first truckloads of recycled styrene monomer (SM) have arrived at INEOS Styrolution’s Antwerp site. The material was supplied by Indaver from its new depolymerisation plant, the first facility in Europe dedicated to polystyrene recycling, inaugurated on 25th September 2025. Also located in Antwerp, this local set-up keeps the supply chain short and sustainable.

This is the first commercial-scale delivery of recycled SM in Europe. It enables the production of high-quality polystyrene and other styrenics, including for food-grade, transparent, and medical applications.
This recycled feedstock adds to INEOS Styrolution’s sustainable styrenics portfolio, which already comprises mechanically recycled and bio-attributed grades, and demonstrates the company’s ability to deploy multiple recycling technologies for different waste streams.
“We are pleased that we can now offer styrenics from depolymerisation at market scale”, remarks Rob Buntinx, President EMEA, INEOS Styrolution. “This gives our customers more sustainable options to lower their environmental footprint without compromising product quality or performance.”
“With Plastics2Chemicals (P2C), Indaver is pioneering in the circular economy and advanced chemical recycling. By converting hard-to-recycle plastics into virgin-quality feedstock such as styrene, we are closing the loop and offering a sustainable alternative to fossil resources”, states Erik Moerman, Sales and Development Director P2C. “Our in-house developed technology, combined with strategic partnerships and continuous innovation, enables us to deliver high-purity materials for demanding applications like food packaging − proving that circularity and performance can go hand in hand.”
This milestone highlights what sets polystyrene apart: it can be broken back down to its original monomer and rebuilt for high-value use. Depolymerisation is also more energy-efficient than other advanced recycling methods such as pyrolysis. It keeps the material in circulation, turning waste back into a valuable resource instead of landfill or litter.
Further information:
Depolymerisation is a chemical recycling process that breaks polystyrene down into its original building block styrene monomer, in contrast to mechanical recycling where plastic waste is physically processed back into pellets, without changing the basic chemical structure of the material. As the material is returned to the molecular level during depolymerisation, it enables the production of new styrenics with the same quality and properties as fossil-based products, including compliance with strict food-contact standards. Compared to conventional fossil-based production, depolymerisation avoids multiple resource-intensive steps, resulting in lower resource use and significantly reduced greenhouse gas emissions.
