Teijin to produce Tenax carbon fiber from ISCC PLUS certified sustainable raw materials

Teijin Limited will begin \ and sales of Tenax Carbon Fiber made with sustainable acrylonitrile (AN) using waste and residue from biomass-derived products or recycled raw materials that have received ISCC PLUS certification from the International Sustainability and Carbon Certification system.

The Tenax Carbon Fiber under ISCC Plus certification will be produced at Teijin’s Mishima plant in Shizuoka Prefecture, Japan, using the mass balance approach. With this method, materials are verifiably tracked through complex value chains, for example, when biomass-derived raw materials are mixed with petroleum-derived raw materials to create products.

The sustainable AN based on ISCC PLUS certification has the same physical properties as petroleum-derived AN; Tenax Carbon Fiber based on this material delivers the same performance attributes and processing as equivalent fossil-based Tenax products.

This similarity allows customers to drop in Tenax Carbon Fiber made with bio-based or circular materials, helping to reduce greenhouse gas (GHG) emissions throughout the product life cycle.

Teijin aims to expand its lineup of sustainable products, so the company is pursuing ISCC PLUS certification not only for carbon fiber including precursor but also for intermediate products such as prepreg and short fiber which use sustainable raw materials.

Further, to strengthen production of sustainable products globally, the company is proceeding with activities to obtain ISCC PLUS certification at overseas locations. Teijin’s European facilities are expected to obtain certification in early fiscal 2024, and US facilities should obtain certification during fiscal 2024.

Teijin switched the fuel for in-house power generation equipment at manufacturing sites from oil to natural gas in2017. Additionaly,Teijin has established life cycle assessment (LCA) evaluation for carbon fiber products related to its products in 2021 and 2022.
