High-performance aramid fibers manufacturer Teijin Aramid (Arnhem, Netherlands) has achieved ISCC Plus certification, acknowledging that the company’s sourcing and processing of alternative feedstocks meet internationally recognized sustainability standards. 

The certification also enables the use of ISCC Plus-certified raw materials —  including bio-based and recycled feedstocks — within a mass balance framework. This approach enables certified and conventional materials to be processed together under controlled conditions, ensuring full traceability and third-party validation.

Teijin’s aramid tires are primarily made with Twaron, a high-performance para-aramid fiber, which is incorporated into the tire’s structure as a cap ply, belt and carcass. According to the company, Twaron fiber-reinforced tire components produced under ISCC Plus can help manufacturers

• Reduce Scope 3 emissions by integrating certified alternative feedstocks
• Meet growing regulatory and OEM requirements for circular materials
• Maintain high mechanical performance across UHP, electric vehicle and commercial tire applications.

Teijin Aramid’s latest sustainability report highlights steady progress across operations, including a 28% reduction in the carbon footprint of Twaron since 2014 and the use of 100% renewable electricity at Dutch production sites. ISCC Plus certification adds an additional layer of transparency and validation at the material sourcing level.

Customers can now make third-party verified sustainability claims for aramid-reinforced tire components, support rolling resistance reduction and lightweight construction goals and participate in emerging circular initiatives such as end-of-life aramid recovery and reuse.

Looking ahead, Teijin Aramid continues to invest in the development of bio-based Twaron variants and is exploring closed-loop recycling models in collaboration with industry partners, all in an effort to support a more sustainable, transparent and high-performance future for the global tire industry.

“The tire industry is under pressure to reduce emissions and adopt circular materials without compromising safety or performance,” says Hendrik de Zeeuw, chief commercial officer at Teijin Aramid. “This certification helps us support our customers with verifiable, lower-impact solutions that meet both technical and sustainability goals.”
