Leigh Fibers is dedicated to the success of their sustainability partners and the support of the circular economy. Leigh recently celebrated their new partnership with Smartwool, The Industrial Commons, and Material Return — building a value chain that will be transformative for the industry and for communities across the US.
At the heart of this partnership is a simple but powerful idea: textiles that have reached the end of their useful life should not become waste. Through this collaboration, worn garments and manufacturing by-products are collected, sorted, and returned to productive use rather than sent to a landfill. It is a working model of circularity — one where post-consumer and post-industrial textile waste becomes the feedstock for new, engineered fiber solutions instead of an environmental liability.
Partnerships like this matter because true circularity cannot be achieved by any single company acting alone. It requires a connected value chain: brands willing to take responsibility for their products' end of life, community-based organizations able to collect and process material, and a re-engineering partner with the technical capability to transform that material into something valuable again. Smartwool brings the brand commitment, The Industrial Commons and Material Return bring the community-rooted collection and sorting infrastructure, and Leigh Fibers brings a century of expertise in turning recovered textiles into high-quality fiber.
The impact extends beyond the environmental benefit of landfill diversion. By building this infrastructure in the United States, the partnership creates local jobs, strengthens regional manufacturing, and demonstrates that a domestic circular economy for textiles is not just aspirational but achievable. It is a template that can be replicated and scaled across the industry.
For Leigh Fibers, this partnership reflects a broader commitment that has defined the company for over a century — proving that responsible material recovery and strong business outcomes are not competing goals, but complementary ones. See more about our partnership.
