Today's KNOWLEDGE Share

World’s first supply chain established for more sustainable polyester fiber based on CO2-derived material as well as renewable and bio-based materials

A consortium of seven companies across five countries has jointly established a supply chain for more sustainable polyester fiber. Instead of fossil materials, renewable and bio-based materials as well as carbon capture and utilization (CCU*) will be used in the manufacturing of polyester fibers for The North Face brand in Japan. The consortium parties are Goldwin, in the role of project owner, Mitsubishi Corporation, Chiyoda Corporation (all three from Japan), SK geo centric (South Korea), Indorama Ventures (Thailand), India Glycols (India) and Neste. 

Neste will provide renewable Neste RE™ as one of the required ingredients for polyester production. The polyester fiber produced in the project is planned to be used by Goldwin for a part of The North Face products, including sports uniforms, in July 2024. After that, the launch of further Goldwin products and brands will be considered. 

The seven companies apply a mass balancing approach to ensure credible traceability of material streams throughout the supply chain and will jointly continue to proactively promote the defossilization of materials to contribute to a more sustainable society.

Regarding the production of para-xylene derived from CO2 as a raw material, the University of Toyama, HighChem Company Limited, Nippon Steel Engineering Co. Ltd., Nippon Steel Corporation, Chiyoda Corporation and Mitsubishi Corporation were granted a NEDO project (New Energy and Industrial Technology Development Organization) status in 2020: "Technology Development for Carbon Recycling and Next Generation Thermal Power Generation/Technology Development for CO2 Emission Reduction and Effective Utilization". They are conducting joint research and development. This project is to supply CO2-derived para-xylene in the course of a trial. It has been produced during the operation process of a pilot plant installed in Chiyoda Corporation's Koyasu Research Park since March 2022.
