Introduction EcoStyrene™ is not just a laboratory breakthrough it’s moving the needle in real industrial environments, catalyzing a transformation in polystyrene (PS) recycling and circularity for global value chains. As brand owners, converters, and waste managers grapple with escalating sustainability demands, EcoStyrene™ provides a scalable, robust, and commercially viable solution to previously unrecyclable polystyrene waste. Market deployments and industry adoption Comme

Introduction EcoStyrene™, Sulzer’s advanced chemical recycling technology, is redefining how industries handle contaminated polystyrene waste. By transforming even severely contaminated PS into pure styrene monomer, EcoStyrene™ delivers impressive gains in both sustainability and operational economics helping operators and brands meet increasing recycling targets and regulatory demands. Key economic benefits Broad Feedstock Acceptance: processes low-value, contaminated PS (wi

Introduction Polystyrene is everywhere used for food packaging, electronics, insulation, and more. Yet for decades, most polystyrene waste has ended up incinerated or landfilled, largely because it’s difficult to recycle contaminated or colored PS, and mechanical recycling offers only low-value, downcycled output. Sulzer EcoStyrene™ is changing the narrative, opening the door for truly circular, high-grade recycling even for the dirtiest, most contaminated polystyrene streams

Introduction The dream of a circular economy in plastics depends on technologies that can recycle post-consumer waste back into materials with virgin-quality performance. For polystyrene widely used in packaging, electronics, and construction contamination and additives have historically blocked true recycling. Sulzer EcoStyrene™ is fundamentally changing the game, converting even contaminated polystyrene into styrene monomer suitable for food-grade and high-spec applications

Introduction Polystyrene (PS) is everywhere from food packaging and disposable cups to insulation panels and electronics. Yet PS recycling has long lagged behind other plastics, primarily due to high levels of contamination and the technical difficulty of purifying waste-derived styrene. Sulzer’s EcoStyrene™ technology is redefining what’s possible: turning even heavily contaminated polystyrene waste into ultra-high purity styrene monomer, closing the loop for circular, food-
