Teijin to Produce
Carbon Fiber from ISCC PLUS Certified Sustainable
Raw Materials

Tokyo, Japan, Decenver 21, 2023 --- Teijin Limited announced today that it will begin
production and sales of TenaxTM Carbon Fiber made with sustainable acrylonitrile (AN)using waste and residue from biomass-derived products or recycled raw materials thathave received ISCC PLUS certification from the International Sustainability and Carbon
Certification system. The TenaxTM Carbon Fiber under ISCC Plus certification will be
produced at Teijin’s Mishima plant in Shizuoka Prefecture, Japan, using the massbalance approach. With this method, materials are verifiably tracked through complex
value chains, for example, when biomass-derived raw materials are mixed withpetroleum-derived raw materials to create products.

TenaxTM Carbon FiberThis initiative will advance the Teijin Group’s efforts to minimize the negative impact on
the environment and society associated with its business activities. The company strives
to protect the global environment in accordance with its long-term vision.
The sustainable AN based on ISCC PLUS certification has the same physical properties
as petroleum-derived AN, TenaxTM Carbon Fiber based on this material delivers the same
performance attributes and processing as equivalent fossil-based TenaxTM products. Thissimilarity allows customers to easily drop in TenaxTM Carbon Fiber made with bio-basedor circular materials, helping to reduce greenhouse gas (GHG) emissions throughout theproduct 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 forintermediate 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 U.S. facilities should obtain certification during fiscal 2024.

Carbon fiber, a light and strong reinforcement material, is used in a wide range of markets,
including aerospace, automotive and sporting goods. With growing pressure to reduce
GHG emissions throughout the product lifecycle, the materials industry is striving toreduce the environmental impact of manufacturing processes involving carbon fiber
throughout the supply chain.
Under these circumstances, Teijin has switched the fuel for in-house power generationequipment at manufacturing sites from oil fired power generation 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. Furthermore, in June
2023, we obtained ISCC PLUS certification for TenaxTM Carbon Fiber and thepolyacrylonitrile (PAN) precursor fiber produced at Teijin’s Mishima Plant in Shizuoka
Prefecture, Japan.
