Indorama Ventures Public Co. Ltd., a global sustainable chemical company, is advancing the textile industry’s move toward low-carbon materials through its scalable, high-performance bio-based PET fibers and yarns, offered under the deja Bio portfolio.

At the Dornbirn Global Fiber Congress, scheduled for September 10-12, Claire Mattelet, Global Sustainability Program Head for Indorama Ventures’ Fibers Business, will present the company’s progress in building a fully certified, low-carbon supply chain at scale.

The company uses a mass-balance approach, where renewable feedstocks such as used cooking oil are blended with fossil-based raw materials within existing production systems. The renewable content is then assigned to the final products through certified methods like ISCC+, ensuring full traceability and compliance with chain-of-custody standards.

By combining current infrastructure with strong R&D capabilities and established technologies, Indorama Ventures is able to bring bio-based PET fibers and yarns to the market quickly. These fibers are chemically identical to fossil-based options, which means no changes are required in customer processes. They match virgin materials in durability, dyeability, and strength, allowing brand owners and converters to shorten qualification timelines and lower scope 3 emissions while smoothly upgrading existing product lines.
