Lummus Technology and Sumitomo Chemical have announced the commercial availability of their highly-efficient Polymethyl Methacrylate Chemical Recycling (PMMA-CR) technology. This builds on the strategic partnership between Lummus and Sumitomo Chemical, first announced in May 2024, to co-develop and commercialize technologies that support circularity and carbon-neutral society across the petrochemical value chain.
“By uniting Lummus’ process expertise with Sumitomo Chemical’s materials innovation, we’re delivering a scalable, economically viable PMMA recycling solution,” said Leon de Bruyn, president and chief executive officer, Lummus Technology. “This gives our customers a clear pathway to reduce waste, lower emissions and unlock new value from recycled materials—turning sustainability into a competitive advantage.”
“We are proud to deliver this innovative PMMA-CR technology to market together with our trusted partner, Lummus Technology,” said Seiji Takeuchi, Senior Managing Executive Officer, Sumitomo Chemical. “Through commercial licensing, we will contribute to the realization of a circular economy by enabling the recycling of PMMA.”
Since establishing the partnership in 2024, Lummus and Sumitomo Chemical advanced development and commercialization of the PMMA-CR technology, including successful validation at Sumitomo Chemical’s pilot plant in Japan.
The PMMA-CR technology recycles end of life PMMA back into high purity methyl methacrylate (MMA) monomer. Its depolymerization system, developed by The Japan Steel Works, Ltd. and Sumitomo Chemical, produces recycled MMA that matches the quality of fossil derived material. The process is also expected to cut life cycle greenhouse gas emissions by approximately 50%, reducing plastic waste and reliance on fossil based feedstocks.
The key technology features include, highly efficient PMMA recycling process, advanced depolymerization system, continuous operation capacity, scalable & modular, and circular integration.
With PMMA CR technology now available for licensing, Lummus and Sumitomo Chemical say that they are ready to support customers’ transition toward circular PMMA, help improve resource efficiency and reduce environmental impact.
