A landmark polyester LCA study from Textile Exchange and SCS Consulting Services has released environmental impact data that the textile industry has long needed. The research directly addresses critical gaps in publicly available life cycle assessment data for both virgin and recycled polyester. Asia, which accounts for over half of global polyester output, was a primary focus of the new findings.
This initiative builds on an earlier SCS study conducted for the UN Fashion Industry Charter, which identified significant deficiencies in environmental reporting. That prior work spotlighted weaknesses in data coverage for thermomechanical and chemical recycling pathways, as well as virgin polyester production across Asia. The new study responds with primary data collected between 2022 and 2024 from seven facilities worldwide.
Energy Sourcing Drives Polyester Climate Performance
The research confirms that energy mix has a decisive effect on polyester's climate footprint. Transitioning to renewable energy can "substantially reduce" polyester's environmental impact, while reliance on coal-intensive grids significantly worsens it. This finding places energy sourcing at the center of sustainable fiber production strategy.
For manufacturers and suppliers, the energy source used in production is as consequential as the raw material choice itself. Reducing carbon intensity through cleaner energy grids offers one of the most effective levers for improving polyester's sustainability profile.
Two Recycling Paths, Different Environmental Trade-offs
The study evaluates two primary recycling approaches for polyester production:
- Thermomechanical recycling: Generally less resource-intensive, but requires clean, high-quality material inputs to function effectively.
- Chemical recycling: Capable of processing complex waste streams but demands greater energy and chemical resources.
Neither method offers a universal solution. The research recommends combining multiple technologies to scale circularity in recycled polyester production across the industry.
Post-consumer sorting remains a significant barrier. Commercial-scale chemical recycling currently focuses on post-industrial waste due to the complex logistics involved in processing consumer materials. Improving sorting and preprocessing infrastructure across the value chain is essential for expanding recycled polyester from consumer sources. Transportation distance also meaningfully affects overall environmental performance, making local waste sourcing a practical strategy for reducing impact.
New Public Benchmarks for Virgin and Recycled Polyester
A central contribution of this polyester LCA study is the publication of new publicly available data covering:
- Virgin polyester produced in Southeast Asia
- Recycled polyester from China, Europe, and the United States
- First-ever public primary data for virgin polyethylene terephthalate (PET) in Asia — including melt, chip, and staple fiber from Southeast Asia
The research followed ISO 14044 standards and complied with the Higg Materials Sustainability Index requirements. Primary data was collected from three chemical recycling operations, three thermomechanical recycling operations, and one virgin PET producer between 2022 and 2024.
Beth Jensen, Chief Impact Officer at Textile Exchange, underscored the study's significance. She stated: "By addressing known data gaps across both virgin and recycled polyester, and by identifying major hotspot impact areas, these findings create a stronger foundation for making informed decisions that support the shift toward preferred production systems."
Frequently Asked Questions
