Arlanxeo and Covestro advance sustainable rubber production with ISCC PLUS-certified materials
The Hague, the Netherlands – 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.
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, marking an important milestone in the company’s sustainability journey and its commitment to a more sustainable value chain.
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.
“Integrating ISCC PLUS-certified materials into our production is a key step in reducing the environmental footprint of our CR 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.
“At Covestro, we support our customers in reducing emissions along the value chain by supplying more sustainable basic chemical raw materials from our multiple ISCC PLUS-certified production sites,” said Moritz Winterstein, Head of Trading Cluster Basic Chemicals EMEA at Covestro. “Our collaboration with ARLANXEO demonstrates how certified raw materials and renewable electricity can contribute to lowering the product environmental footprint of downstream applications and support customers in achieving their sustainability targets.”
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.
