Trinseo Opens Next-Gen Depolymerization Facility in Italy

Trinseo has opened a polymethyl methacrylate (PMMA) depolymerization facility in Rho, Italy. The pilot facility represents a significant step forward in the company’s commitment to sustainability, as the next-generation recycling technology helps advance a circular infrastructure for acrylic solutions and is aligned with Trinseo’s 2030 Sustainable Product Portfolio Goals.

We are thrilled about the opening of our depolymerization facility, which will help advance our goal to support a circular economy,” said Francesca Reverberi, Senior Vice President of Engineered Materials and Chief Sustainability Officer at Trinseo. “Our company remains committed to our sustainability goals, including investing in new recycling technologies that can support our customers in reaching their sustainability goals as well.”

Depolymerization is a chemical recycling process that returns acrylic solutions to the constituent monomer, methyl methacrylate (MMA). Complementary to other recycling technologies, depolymerization helps close the loop for acrylic recycling with several advantages over traditional processes. By utilizing this technology, acrylic solutions can be recycled—including PMMA sheets, which previously could not be mechanically recycled. Additionally, returning the material to its monomer form allows additives and contaminants to be removed from pre- and post-consumer acrylic products. This enables more PMMA to be recycled.

Trinseo’s PMMA depolymerization facility delivers a next-generation technology, utilizing an advanced continuous process to produce high-purity regenerated MMA from pre- and post-consumer acrylic solutions. Trinseo’s depolymerization technology leverages findings from the MMAtwo Consortium, a collaborative initiative funded by the European Union’s Horizon 2020 research and innovation program, to develop a new value chain for pre- and post-consumer PMMA and a versatile recycling process for converting this waste into high-quality regenerated monomer with carbon footprint reduction versus virgin MMA.
