Röhm introduces industrial PMMA recycling technology, enabling high-quality MMA recovery, supporting circular economy goals, reducing emissions, and advancing sustainable plastics production.
Röhm GmbH has taken a significant step toward advancing circular plastics by introducing a newly developed chemical recycling process for polymethyl methacrylate (PMMA) at its Worms facility in Germany. This marks the first time the company has deployed this proprietary technology at an industrial scale, highlighting its commitment to sustainable material innovation. The process focuses on converting end-of-life PMMA back into its original monomer, methyl methacrylate (MMA), through a method known as depolymerization. This approach allows the recovered material to regain a quality comparable to virgin-grade MMA, thereby enabling its reuse in high-performance applications.
PMMA is widely used across industries due to its clarity, durability, and versatility. It is commonly found in products such as automotive taillights, medical equipment, and a variety of consumer and industrial goods. One of the key advantages of PMMA lies in its chemical structure, which makes it particularly well-suited for efficient recycling. Through depolymerization, more than 90 percent of the material can be recovered as high-quality MMA, making it an ideal candidate for circular economy initiatives.
The newly implemented recycling technology has been designed to integrate seamlessly into Röhm’s existing MMA production infrastructure in Worms. This compatibility allows the company to scale operations efficiently without the need for entirely new production systems. By making this investment, Röhm is laying the groundwork for a fully closed-loop material cycle that can be expanded over time. Beginning in the summer of 2027, the company plans to incorporate the recycled MMA into its sustainable proTerra product line, which is produced across its interconnected Verbund manufacturing network.
This industrial-scale rollout also aligns with Röhm’s involvement in the European Recycling Alliance for PMMA, a collaborative initiative established in late 2024. The alliance brings together multiple industry stakeholders with the shared objective of significantly improving the recycling rates of PMMA waste throughout Europe. The ultimate goal is to create a comprehensive and fully closed material loop for PMMA products across the continent.
Each partner within the alliance contributes a specific function to the recycling chain. Pekutherm is responsible for collecting and sorting approximately 5,000 tons of PMMA waste annually from across Europe. This material is then processed by MyRemono, which converts it into recycled MMA (rMMA) through depolymerization techniques. Finally, Röhm upgrades this intermediate product into MMA of virgin-grade quality at its Worms facility, ensuring that it can be reused in demanding applications without compromising performance.
According to Lukas Dössel, Röhm’s Director of Circular Economy, the development of rMMA represents a major milestone in closing the loop within the PMMA value chain. He emphasized that this innovation will help customers comply with increasingly stringent regulatory requirements while also promoting sustainable resource use. The initiative supports broader efforts to reduce reliance on fossil-based raw materials and to transition toward more environmentally responsible production models.
The project has received financial support from the German Federal Ministry for Economic Affairs and Energy. This backing is part of a broader funding program aimed at helping industrial companies reduce energy consumption, conserve resources, and lower greenhouse gas emissions. Dössel noted that Röhm views this investment not just as a compliance measure, but as a proactive effort to lead the transformation toward a more circular plastics economy. By embracing innovative recycling technologies, the company aims to play a central role in shaping a more sustainable future for the industry.
