Carbon fiber manufacturer Teijin is to start production of its Tenax material, which is manufactured from 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.
Teijin states that the material will be produced under ISCC Plus certification at its Mishima plant in Shizuoka Prefecture, Japan, using the mass balance approach. With this method, materials are 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 has the same physical properties as petroleum-derived AN and delivers the same performance attributes and processing as equivalent fossil fuel-based products. This similarity allows customers to easily drop in Tenax made with bio-based or circular materials, helping to reduce greenhouse gas emissions throughout the product lifecycle.
Teijin aims to expand its line-up of sustainable products and is pursuing ISCC Plus certification not only for carbon fiber but also for intermediate products such as pre-preg and short fiber which use sustainable raw materials.
