Introduction
Indorama Ventures is advancing the textile industry's shift to low-carbon materials with its bio-based PET fibers and yarns under the deja™ Bio portfolio. The company has developed a scalable, certified supply chain to support this transition.
Upcoming Presentation
Claire Mattelet, Global Sustainability Program Head for Indorama Ventures’ Fibers Business, will discuss the company's experience at the Dornbirn Global Fiber Congress from September 10-12. Her presentation will cover the development of a fully certified, low-carbon supply chain at scale.
Challenges and Solutions
Key challenges include securing renewable feedstocks for bio-based PTA and MEG production, converting these into PET chips, yarns, and fibers, and navigating complex certification requirements. Indorama Ventures addresses these by using a mass-balance approach, blending renewable feedstocks with fossil-based materials in existing systems.
Mass-Balance Approach
The mass-balance method involves blending renewable feedstocks, like used cooking oil, with fossil materials. The renewable content is allocated to final products using certified methods such as ISCC+, ensuring traceability and compliance with chain-of-custody requirements.
Market Deployment
By leveraging existing infrastructure and proven technologies, Indorama Ventures enables rapid market deployment of bio-based PET fibers and yarns. These products are chemically identical to fossil counterparts, ensuring consistent performance metrics and allowing brand owners to reduce scope 3 emissions while upgrading product lines.
