For years, fashion companies have spoken about circularity. But why has it not happened sooner? One of the biggest impediments has been industrial: building the plants, supply chains and commercial commitments needed to turn a mixed cotton-polyester shirt into new raw materials at a cost manufacturers will actually pay.

A new partnership between Circ and materials giant Huafon could test whether fashion’s circularity ambitions can finally move from pilot projects to industrial infrastructure.

The announcement comes as regulation is beginning to change fashion’s waste calculus. The European Union’s new rules restricting the destruction of unsold apparel took effect for large companies this year, and its revised Waste Framework Directive requires member states to establish extended producer-responsibility systems for textiles. Those policies do not automatically create a functioning recycling industry, but they sharpen the financial question for brands: what happens to products when they cannot be sold, reused or repaired?

Circ, a textile recycling company that started in the US and then launched a facility in France, is betting that China is where that problem can begin to be solved.

The company has announced a partnership with Huafon, one of China’s largest advanced materials groups, to develop a multi-phase textile-to-textile recycling site in China. The first phase is designed to process roughly 200 metric tons of textile waste a day. Circ’s process is designed to take old cotton-polyester clothing, separate the two materials, and turn them into ingredients for new polyester and new cellulose-based fibers such as lyocell.

That matters because China is one of the world’s largest manufacturing centers for textiles and clothing. If fiber-to-fiber recycling remains confined to small demonstration plants, it will struggle to reshape the supply chains that produce most of the world’s garments in the first place.

“China is at the center of global textile production, making it a critical location for scaling textile-to-textile recycling,” Peter Majeranowski, Circ’s chief executive, says.

Circ’s technology targets one of fashion’s most persistent waste problems: blended fabrics. Polyester and cotton are widely used together because the combination is durable, affordable and versatile. But the blend is difficult to recycle. Most existing systems work best with a single material or polyester-rich feedstock. Cotton-polyester garments tend to be downcycled, burned, landfilled or exported into an opaque global secondhand market.

Huafon says that gap was central to its interest in Circ. “Circ has developed one of the most promising textile-to-textile recycling technologies we have seen, and Huafon is ready to help bring it to market,” Feifeng You, vice president of Huafon Group and chairman of Huafon Microfibre Shanghai Tech Co. Ltd., notes. “By combining Circ’s innovation with our industrial strength and investment, we can turn textile waste into high-quality materials at a scale the industry needs.”

More Than A Recycling Deal

The partnership is significant not simply because Huafon is supplying a site. Rather, the company is investing directly in the project and brings something start-ups typically lack: existing chemical production facilities, engineering and procurement systems, logistics networks, operating teams and relationships across China’s textile industry. Huafon also owns Covation Biomaterials , the former DuPont biomaterials business, which gave the group experience commercializing bio-based materials, including Sorona, a partly corn-based performance fiber used in carpeting and apparel.

Majeranowski says that experience made Huafon more than a conventional manufacturing partner. “Circularity is a team sport. Now, we’re at the phase that includes the scaling.”

That distinction gets at why so many fashion recycling ventures have struggled to move beyond the pilot stage. A company may prove its process in a lab, produce a capsule collection with a brand and still face the far more difficult work of building a plant that can run consistently, secure waste feedstock, meet a manufacturer’s exact specifications and sell its output at a viable price.

“Now, six, seven years later, they’re ready to deploy,” Majeranowski says of the broader field of textile recycling technologies. “What’s difficult is the industry is so non-concentrated. Even your biggest brand is responsible for less than 1% of what’s produced every year in textiles. So no one really wants to take the first step.”

The result? A stalemate. Investors want evidence that brands will buy recycled materials before financing new facilities. Brands want reliable supply and lower prices before they commit. And recyclers cannot reduce their costs without the volume those commitments would create.

Circ’s answer is to partner with an industrial company already embedded in the market it hopes to serve. Rather than constructing every capability from scratch, the company can place its technology inside an existing chemical and materials footprint.

Feifeng You noted that Circ had already moved beyond lab scale, had materials in market, and had accumulated operational and engineering data. The company had seen little comparable technology focused on polycotton blends, even as polyester-to-polyester recycling expands in China.

The Push For Price Parity

That does not mean the economics are settled. Majeranowski says Circ still needs scale to approach parity with virgin materials. “This industry started the Industrial Revolution. It’s super big and optimized,” he explains. “For our process, we just need scale. So really, within five years of the first plant, we’re going to be at price parity, we predict.”

Currently, low-cost virgin polyester remains tied to fossil fuel markets and fashion procurement teams remain intensely price sensitive. Even Feifeng You acknowledges that customers may accept a premium during early commercialization, but says long-term adoption will require recycled materials to compete with virgin alternatives on both performance and economics. Plant utilization, energy, capital costs, feedstock quality, and operating efficiency will all determine whether that happens.

Still, the China location could change the speed of the experiment. Circ’s recovered chemical outputs are familiar inputs for existing manufacturing: polyester monomers can enter established polymerization lines, while cellulosic pulp can feed viscose and lyocell production. The task is less about creating an entirely new industrial ecosystem than integrating a new process into the one that already exists.

Nicole Rycroft, founder and executive director of Canopy , says the Circ-Huafon deal arrives as brands and man-made cellulosic fiber producers look for materials that can reduce pressure on forests, fossil inputs and volatile supply chains. “Partnerships between global suppliers and leading innovators is exactly the direction fashion brands need their supply chains to go,” she says.

Canopy’s recent modeling found that reaching just 5% use of next-generation inputs in viscose could unlock savings for brands over the next decade and help set the sector on a path toward far greater adoption by 2036. Whether those projections materialize will depend on whether projects like Circ’s can deliver actual material, not only promising samples.

The Missing Infrastructure

Circ’s new Chinese facility will not solve fashion’s waste problem on its own, however. The company still needs reliable streams of discarded textiles, and the apparel industry remains poorly organized around collecting, sorting and channeling post-consumer clothing into recycling. Majeranowski notes that most brands are still not equipped to aggregate their own waste at scale. Mills, distributors, waste handlers, retailers and consumers all control different parts of the chain.

That is why this collaboration may be more consequential than a typical materials announcement. The central question is no longer whether a company can separate polyester from cotton. Circ has already demonstrated that it can. The question is whether a recycler, a chemical manufacturer, brands, and suppliers can coordinate quickly enough to build a real market around the output.

“We’re not a technology company anymore,” Majeranowski says. “We’re a coordination company.”

For the fashion industry, which has spent years announcing circular collections without building much circular infrastructure, China may be the place where that distinction finally gets tested.
