Circ announces New Fiber Club partners to accelerate commercial adoption of recycled textiles
Circ is expanding its Fiber Club initiative, bringing together a new group of brand and supply chain partners to help move recycled materials from pilot stages into commercial use.
The latest cohort includes lifestyle brand Madewell under J.Crew Group, sustainable fashion label Reformation, and European retailer C&A. They join supply chain partners Lenzing and Linz Textil to develop products using recycled inputs.
Fiber Club was first introduced in January 2025 with brands Bestseller, Eileen Fisher, Everlane, and Zalando, alongside supply partners Arvind, Birla Cellulose, and Foshan Chicley.
The program focuses on two long-standing barriers to adopting new materials: minimum order volumes and pricing. By combining demand across pulp, fiber, and yarn stages, Fiber Club creates a shared sourcing model that allows brands to test and scale recycled materials without committing to large individual orders.
Each participating brand is developing collections using fibers made with 30% Circ pulp derived from recycled polycotton textile waste. Circ supplies the recycled pulp, which Lenzing processes into lyocell fibers using its REFIBRA™ process. Linz Textil then spins the fibers into yarn. Brands select their own fabric mills and garment manufacturers, allowing the material to fit into existing production networks.
This structure is designed to make adoption easier for companies already working with Lenzing fibers while also expanding the number of manufacturers capable of producing circular textiles at scale.
The expansion comes as regulatory and market pressures increase. Proposed extended producer responsibility policies in the United States and Europe signal that brands may soon be required to take greater accountability for textile waste and invest in recycling systems. At the same time, many companies are seeking materials that can meet sustainability targets without disrupting established supply chains.
Peter Majeranowski, CEO of Circ, said the company is now focused on lowering the barriers to commercialization following validation of its recycling technology. He noted that brands face growing pressure to reduce waste and shift toward better material choices, while also needing solutions that work within current manufacturing systems.
Fiber Club aims to address that gap by aligning demand, production, and sourcing—turning early-stage material trials into repeatable, scalable supply.
