USFibers, the largest vertically integrated recycler and producer of polyester staple fiber in the United States, has secured a new strategic investment from Glisco Partners and Orion Infrastructure Capital to expand production capacity, enhance technical capabilities, improve efficiency, and reach new markets.
Founded in 1994 and headquartered in Trenton, South Carolina, USFibers operates a fully integrated platform that converts post-industrial and post-consumer PET waste into high-quality fiber products while diverting byproducts from landfills. The company serves end markets including automotive, filtration, and geotextiles, and is recognized for its technical expertise, customized product offerings, and long-standing customer relationships.
The investment marks the next phase of USFibers’ growth following three decades of building the company’s recycling and manufacturing platform under the leadership of CEO Teddy Oh. The capital will support expanded production capacity to meet growing demand across key end markets, enhanced technical and product capabilities focused on specialized and engineered fiber solutions, potential expansion into new markets and value-added services, and continued investment in recycling infrastructure. USFibers will continue to operate under its existing management team, maintaining the company’s culture, operational excellence, and long-standing relationships with customers and suppliers. According to the Circularity Gap Report 2025, the world consumes approximately 106 billion tons of materials annually but only 6.9% comes from recycled sources, underscoring the market opportunity that USFibers is positioned to address.
Glisco Partners, a leading independent private equity firm with more than 20 years of history specializing in private equity and real estate investments in North America, characterized the partnership as an opportunity to support USFibers’ business vision and growth plans with both capital and operational expertise. Orion Infrastructure Capital, which manages approximately $6.5 billion in assets, framed the investment as supporting USFibers’ expansion in a market with growing demand for recycled polyester and high value-add applications, with the goal of creating a stronger and more resilient supply chain for customers and suppliers alike.
The deal reflects growing institutional appetite for investments in circular economy infrastructure as demand for sustainable materials accelerates across automotive, industrial, and consumer goods supply chains. USFibers’ vertically integrated model, which spans collection, processing, and manufacturing, positions the company as a preferred partner for customers seeking traceable, domestically produced recycled fiber content.
Support: TM Capital, a division of Capstone Partners, served as exclusive financial advisor to USFibers.
