ARLANXEO and Covestro are collaborating to advance more sustainable solutions in synthetic rubber production. By transitioning to the use of ISCC PLUS-certified chlorine from Covestro in its chloroprene rubber (CR) production, ARLANXEO has reduced the product environmental footprint (PEF) of its Baypren^® product portfolio. ISCC PLUS-certified chlorine from Covestro is produced by using electricity from renewable sources.

As of January 2026, the entire CR production of ARLANXEO is based on ISCC PLUS-certified chlorine. The  transition is resulting in an average reduction in global warming potential (GWP) of approximately 20% compared to 2025 levels1, depending on the specific product grade.

“Integrating ISCC PLUS-certified materials into our production is a key step in reducing the environmental footprint of our CR rubber products,” said Niels van der Aar, head of Sustainability at ARLANXEO. “It underlines our commitment to supporting customers with more sustainable material solutions while advancing transparency along the value chain by supplying corresponding product environmental footprint data for ARLANXEO’s entire CR product portfolio.”

As a key chemical supplier to ARLANXEO, Covestro plays a crucial role in enabling this transition by supporting the availability of ISCC PLUS-certified chlorine.

The introduction of ISCC PLUS-certified feedstock, like ISCC PLUS Chlorine, strengthens the position of ARLANXEO as a leading supplier of more sustainable elastomer solutions, particularly for industries with ambitious climate targets, such as automotive, construction, industrial and adhesive applications. In addition, ARLANXEO can also offer Baypren® Eco grades combining ISCC PLUS-certified chlorine and ISCC PLUS-certified butadiene, enabling further reductions in environmental impact and supporting customers in achieving their sustainability targets without any compromise in performance.
