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

Teijin Limited is to begin producing and selling 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.

This initiative will advance the Teijin Group’s efforts to minimize the negative impact on the environment and society associated with its business activities. 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.

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.

In June 2023, Teijin obtained ISCC PLUS certification for Tenax Carbon Fiber and the polyacrylonitrile (PAN) precursor fiber produced at Teijin’s Mishima plant.

Teijin’s European facilities are expected to obtain certification in early fiscal 2024, and US facilities should obtain certification during fiscal 2024.
