Teijin’s TenaxTM and PAN to Earn ISCC PLUS
Certification for Bio-based and Circular Raw Materials
Tokyo, Japan, June 29, 2023 --- Teijin Limited announced today that its TenaxTM Carbon
Fiber and the polyacrylonitrile (PAN) precursor fiber produced at Teijin’s Mishima Plant
in Shizuoka Prefecture, Japan have received ISCC PLUS certification from theInternational Sustainability and Carbon Certification system. This is the world’s firstachievement that carbon fiber and PAN to simultaneously earn this certification, which
is a globally recognized standard for the recovery of waste and residues that provide
feedstocks for circular plastics.

TenaxTM Carbon Fiber

The PAN precursor fiber is made from sustainable acrylonitrile (AN) using waste andresidue from biomass-derived products or recycled raw materials, and produced by using
the mass balance approach method. With this method, materials are verifiably tracked
through complex value chains, for example, when biomass-derived raw materials aremixed with petroleum-derived raw materials to create products.
Because the sustainable AN has the same physical properties as petroleum-derived AN,
PAN and TenaxTM Carbon Fiber based on this material deliver the same physicalproperties as equivalent fossil-based products. This similarity allows customers to easily
replace TenaxTM Carbon Fiber with more-sustainable alternatives that can contribute to
the reduction of greenhouse gas (GHG) emissions throughout the product life cycle.
Teijin expects to begin commercial production of PAN and TenaxTM using the massbalance approach method at the Mishima plant by the first half of 2024. Also, thecompany will pursue ISCC PLUS certification for its carbon fiber and related products
produced in Europe, the United States and Asia to expand availability of its sustainableproducts. This initiative will advance the Teijin Group’s mission of providing innovative,
people-centered solutions that improve the quality of life. Teijin will continue striving tomitigate the impact of its business activities on the environment to realize its long-term
vision of supporting the society of the future.
Carbon fiber, a strong yet lightweight material that can help reduce energy consumption,
is used in a wide range of applications including aerospace and industrial fields.
Meanwhile, the need to reduce GHG emissions throughout supply chains in support ofcarbon neutrality is generating demands for products with a lower environmental impact.
Under these circumstances, Teijin switched the fuel for in-house power generationequipment at manufacturing sites to natural gas and adopted lifecycle assessment (LCA)
to calculate the environmental footprint of its carbon fiber and intermediate materials.
*The Teijin Limited Mishima Plant shall commit and declare compliance with the ISCC PLUS
requirements in accordance with the latest regulations of the ISCC.
