As industries face increasing pressure to address environmental challenges and comply with evolving regulations, Sulzer has embedded Sustainability & Environmental responsibility at the core of its corporate DNA. Through its comprehensive ESG (Environmental, Social, and Governance) strategy, Sulzer actively drives measurable progress toward a more sustainable future. Key pillars of Sulzer’s sustainability strategy include: Setting ambitious carbon reduction targets with a goa

Introduction: skid-mounted plants for a sustainable future The push toward sustainable energy, circular economy, and emissions reduction is accelerating innovation in the process industries. Companies in bio-based chemicals, advanced recycling, and carbon capture need to scale solutions quickly without the delays or risks of traditional plant construction. That’s where Sulzer’s skid-mounted, modular plants change the game, enabling reliable, fast-track projects that deliver e

Introduction Efficient recycling of plastic waste means more than producing fuel it’s about recovering premium chemical streams that offer greater economic and environmental value. Sulzer’s distillation and BTX recovery solutions extract the full potential of purified pyrolysis oils, separating valuable fractions for direct industrial reuse. How Sulzer’s technology works Advanced fractionation & distillation Tailored Column Design: Sulzer distillation units use customized tra

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-

Introduction True circularity in plastics recycling means turning waste into raw materials that are as good as new ready for repeated use in polymer production, rather than being downcycled or disposed of. Sulzer’s MaxFlux™ hydrotreating technology makes this leap possible. By flexibly and efficiently upgrading mixed plastic pyrolysis oils (PPO), MaxFlux™ enables the production of high-grade naphtha, completing the loop for plastics-to-plastics recycling. How MaxFlux™ drives

Introduction In a landmark collaboration set to redefine sustainable fuel production, Sulzer and ANDRITZ have joined forces to enable the production of 12,000 tons of biomethanol annually at the world’s largest facility of its kind. The new plant, operated by Veolia and integrated into Metsä Fibre’s bioproduct mill in Äänekoski, Finland, harnesses cutting-edge separation and purification technologies to convert pulp mill waste into high-value, commercial-grade biomethanol. A

Introduction As the demand for high-quality recycled plastics grows, chemical recyclers are seeking innovative ways to boost monomer recovery from polystyrene (PS) and polymethyl methacrylate (PMMA). The key to maximizing yield and profitability lies in precise process control and advanced quenching technology. Sulzer’s PyroCon™ offers a breakthrough solution, enabling recyclers to achieve higher monomer yields and more sustainable operations. The challenge: efficient monomer

Introduction Chemical recycling is a cornerstone of the circular economy, offering a path to transform plastic and bio-waste into valuable raw materials. However, one persistent challenge in pyrolysis the process at the heart of chemical recycling is effective quenching. Traditional quenching systems often struggle with fouling and inefficient cooling, which can compromise product quality and plant profitability. Sulzer’s PyroCon™ quenching technology is changing the game, de
