The EcoStyrene process tackles a major hurdle in the chemical recycling sector: the effective processing of waste polystyrene materials that contain various contaminants. Unlike traditional recycling methods that require clean feedstock, our innovative technology efficiently handles polystyrene waste embedded with flame retardant components and food residues.

This transformation turns previously non-recyclable materials into valuable resources that can reenter the production cycle, including applications for food contact.

Collaborative Development for Commercial Readiness

This technology has been developed in collaboration with a leading provider experienced in fluid-bed reactor technology. By merging Sulzer’s expertise in polymer recycling processes and equipment with proven reactor technology, we have accelerated the development timeline, making the solution commercially available today.

Building a Polystyrene Alliance

Sulzer Chemtech, alongside its partner, is establishing a polystyrene alliance that spans the entire value chain, from waste managers to brand owners, aiming to valorize polystyrene waste. Chemical recycling operators can now adopt this solution to broaden their acceptable feedstock range, minimize environmental impact, achieve sustainability goals, and extract additional value from materials that were once deemed too contaminated for conventional recycling methods.
