ARLANXEO and Covestro advance sustainable production for synthetic rubber
ARLANXEO and Covestro are strengthening their collaboration 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 significantly reduced the product environmental footprint (PEF) of its Baypren product portfolio.

ARLANXEO’s CR plant in Dormagen, Germany.
ISCC PLUS-certified chlorine from Covestro is produced by using electricity from renewable sources, supporting a more sustainable production process and contributing to lower greenhouse gas emissions.
As of January 2026, ARLANXEO’s entire CR production is based on ISCC PLUS-certified chlorine. This transition is resulting in an average reduction in global warming potential (GWP) of approximately 20% compared to 2025 levels, depending on the specific product grade.
The introduction of ISCC PLUS-certified feedstock, like ISCC PLUS chlorine, strengthens ARLANXEO’s position 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.
