CCU Polyester

Research and development of polyester materials using CO2 as part of the raw materials.

CO2 is generated in various activities that support our daily lives. At GU, in order to respond to climate change, we are conducting research and development to re-examine the way we use materials, aiming to create products with low greenhouse gas emissions.
One of these initiatives is the research and development of polyester materials that utilize CO2 recovered within the factory as part of the raw materials. By using CO2 generated in the factory as a resource, it is hoped that this will lead to more sustainable manufacturing.

Capture CO2 and utilize it as a resource.

Development is underway on Carbon Capture and Utilization (CCU) technology, which involves capturing CO2 generated from factories and other sources and utilizing it as a resource. GU is using this technology to promote research and development of polyester materials that use CO2 as part of their raw materials, in collaboration with partner factories.
Furthermore, the CO2-capture-derived polyester raw material currently under research and development has been confirmed to have approximately 28% lower greenhouse gas emissions during the polyester chip manufacturing stage compared to conventional petroleum-derived polyester raw materials *1*2.

*1 Based on a life cycle assessment conducted by a third party.
*2 This comparison covers greenhouse gas emissions from raw material production to polyester chip production, using CO2 capture-derived polyester raw materials and petroleum-derived polyester raw materials from the same supplier.

Thinking about the future of materials

A variety of materials are used in clothing production.
GU will continue to focus not only on utilizing recycled materials but also on developing new materials using new technologies, and will advance research and development to broaden future options.
