Sustainability certification for carbon fiber

Teijin said that two of the fiber products produced at its plant in Mishima, Japan, have received International Sustainability and Carbon Certification (ISCC) certification.

The company’s Tenax carbon fiber and polyacrylonitrile (PAN) precursor fiber now reportedly meet the ISCC PLUS standard for the recovery of waste and residues that provide feedstocks for circular plastics.

According to Teijin, its PAN precursor fiber is made from sustainable acrylonitrile (AN) using waste and residue from biomass-derived products or recycled raw materials and is produced by using the mass balance approach method. With this method, materials are verifiably tracked through complex value chains, it said. Teijin expects to begin commercial production of PAN and Tenax using this method at the Mishima plant by the first half of 2024.

The company also plans to pursue ISCC PLUS certification for its carbon fiber and related products produced in Europe, the United States and Asia.
