Certification strengthens the ARLANXEO Eco portfolio and supports customers' sustainability goals across North America and beyond

Orange, Texas — March 10, 2026 — ARLANXEO today announced that its Therban® (HNBR) and Buna® (BR) manufacturing units at the Orange, Texas site have successfully achieved ISCC PLUS certification. This certification enables the site to manufacture and supply products under the ARLANXEO Eco label. The ARLANXEO Eco Line comprises the company's portfolio of ISCC PLUS-certified sustainable elastomers based on the mass balance approach.

This certification enables ARLANXEO to offer customers in North America and global markets verified sustainable solutions that help reduce overall carbon footprints while maintaining the performance and reliability associated with Therban® and Buna® products.

The certification is particularly significant for ARLANXEO’s Specialty Elastomers business. As the first Therban® HNBR site to receive ISCC PLUS certification, the Orange location plays a central role in expanding ARLANXEO’s offering of sustainable high performance elastomers. Edwin Grootendorst, Global Head of Business Specialty Elastomers, emphasized the milestone: “The Orange site is the first Therban® HNBR production facility to receive ISCC PLUS certification and further strengthens the sustainability mission of ARLANXEO, as well as the Eco portfolio of the Specialty Elastomers cluster.”

The inclusion of Buna® BR from the Orange site adds further depth to the company’s sustainable product offering. Rohit Prabhune, Global Head of Business Basic Elastomers, highlighted the importance for his segment: “With Orange joining our existing ISCC PLUS-certified Buna® sites, ARLANXEO now has ISCC+ Certified Basic Elastomers producing sites on 3 continents, with a truly global reach. This reinforces our commitment to providing customers with circular, mass balanced solutions that help reduce environmental impact while maintaining the performance they expect.”

The strengthened product offering is particularly relevant for customers in North America. Jay Capelli, Regional Head of Sales NORAM, added: “This certification helps solidify ARLANXEO’s position in the NORAM region as a premium supplier and partner – and supports the sustainability ambitions of our customers across key industries.”

The certification of the Orange site is part of ARLANXEO’s broader global sustainability agenda and represents another milestone in expanding the ARLANXEO Eco portfolio across multiple sites and product families — supporting customers in their transition toward more sustainable elastomer solutions.
