Circ has announced the expansion of its Fiber Club initiative, welcoming a new group of global brand and supply chain partners aimed at accelerating the commercial adoption of recycled textiles.
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 strengthen circular material integration across the value chain.
Building on a Proven Model
Originally launched in January 2025 with partners including Bestseller, Eileen Fisher, Everlane and Zalando, Fiber Club was designed to address long-standing barriers such as minimum order quantities and pricing challenges that have slowed the uptake of next-generation recycled materials.
By aggregating demand across pulp, fiber and yarn production stages, the initiative enables brands to move beyond pilot projects toward commercial product launches and long-term material commitments.

From Textile Waste to Commercial Fiber
Under the expanded model, participating brands are developing collections using TENCEL™ | Circ® with REFIBRA™ technology, incorporating 30% Circ pulp derived from recycled polycotton textile waste.
Circ supplies the recycled pulp, which Lenzing converts into TENCEL™ | Circ® with REFIBRA™ lyocell fibers. Linz Textil then spins the fibers into yarn, while brands nominate their preferred fabric and garment manufacturers to integrate the materials into existing production systems.
This collaborative approach allows brands already working with Lenzing fibers to seamlessly adopt Circ materials, while expanding the network of manufacturers capable of producing circular textiles at scale.
Responding to Regulatory and Market Pressure
The Fiber Club expansion comes as regulatory frameworks in the U.S. and Europe increasingly emphasize extended producer responsibility (EPR) and textile waste accountability. Growing consumer expectations and sustainability mandates are driving brands to prioritize recycled inputs and scalable circular solutions.
“With Circ’s technology proven, the next phase of scaling is to lower the barriers to commercialization,” said Peter Majeranowski, CEO of Circ. “The Fiber Club model operates within existing manufacturing systems to address the costs and complexity that have held brands back, making circular materials viable today.”
By aligning brand demand with supply chain capacity, Circ aims to position recycled textiles not as experimental alternatives, but as commercially viable materials embedded within mainstream apparel production.
