Few corners of the fashion industry are as overpromised — or as structurally complex to scale — as material innovation.
And an even smaller subset has managed to convince backers that the next-gen materials they’re developing could deliver real, near-term impact — unlocking capital to move beyond lab-scale pilots, expand technical teams and push toward commercial production.
WWD’s sister publication Sourcing Journal tracked material innovators’ moves — and their influence on the fashion supply chain — throughout the year. In 2025, investors showed particular interest in alternative feedstocks, recycling technologies for hard-to-process fibers and platform approaches that promise cost parity with incumbent materials. Manufacturing-ready innovation — which focuses less on discovery and more on scale, reliability and throughput — also drew increased attention.

SuperCircle
SuperCircle, an AI-powered platform for managing retail textile waste, secured $24 million in series A funding led by the Boulder-based Foundry Group, a network-driven venture capital firm managing over $3 billion for said network, earlier this month.
Other investors backing the full-stack textile recycling startup include BBG Ventures, a New York early-stage “generalist” fund, as well as Renewal Fund and Elemental Impact.
“Retail needs a turnkey system that flips the script on its waste reckoning: turning would-be cost centers into revenue streams,” said Nisha Dua, managing partner at BBG Ventures. “SuperCircle has built the digital infrastructure to move the industry beyond incremental fixes and point solutions — enabling an entirely new system at scale.”
SuperCircle said the funding will “propel” the waste management platform’s expansion, accelerating its technology development, bolstering its supply chain integrations and growing its reverse logistics footprint.
“We built SuperCircle to give retailers a scalable and financially sound system for end-of-life,” said Chloe Songer, cofounder and chief executive officer of SuperCircle. “Enabling value generation from textiles — long after purchase via consumer trade-in — and drastically reducing supply chain losses on excess, damages and returns: capturing maximum value from every T-shirt, sneaker, sheet set and handbag produced.”
AMSilk
In September, the OG industrial supplier of vegan silk biopolymers, AMSilk, secured 52 million euros — equivalent to roughly $61.1 million — in a strategic financing round led by existing investor Athos, plus participation from MIG Capital and Novo Holdings.
“AMSilk’s transition to full-scale production signals strong commercial validation,” said Daniel Kolb, investment manager at Athos, a Munich-based single-family office. “The company’s ability to manufacture biofabricated materials at multi-ton volumes confirms its industrial viability and readiness to meet growing market demand.”
Eeden
On the heels of a proven-positive pilot plant, German chemical textile recycler Eeden raised over $20 million (18 million euros) during a series A financing round in mid-May.
Known for its scientific solution to the mounting mountain of textile waste, Eeden’s chemical recycling technology recovers pure cellulose and polyethylene terephthalate (PET) building blocks from cotton-polyester blends. The fresh funding will allow the start-up to build out its Münster-based demonstration plant, alongside investments into commercial projects with industry insiders and large-scale processing optimization efforts.
Able to recover a garment’s cellulose and cotton while breaking down polyester’s monomers, Eeden’s output can be used to produce lyocell, viscose and polyester fibers of virgin quality; ideally providing an alternative to the resource-draining incumbent — at scale and price-parity — while “unlocking” previously closed circular value chains.
Venture capital firm Forbion, based in the Netherlands, led the round through its BioEconomy Fund. The Naarden-based neighbor’s nascent investment strategy focused on biobased innovation — more specifically, biotech within the food, agriculture, materials and environmental technology sectors — aligned against the United Nations’ Sustainable Development Goals.
To note, Eeden previously closed seven-figure seed funding rounds in June and November 2022. All existing investors returned for this latest round.
Circ
Textile-to-textile recycler Circ closed $25 million in oversubscribed funding in a March round, led by asset management company Taranis and its Carbon Ventures fund, with continued support from existing strategic investors like Inditex and Avery Dennison.
Circ said the funding will build on the “major technical commercial progress” the polycotton textile waste pulp producer made over the past 18 months, as the additional funds will help “fuel” the Mara Hoffman partner’s push to scale its recycling technology as the start-up works to “transform” the industry’s waste problem.
The self-proclaimed single demonstrator of successfully recycling polycotton to recover both textile fractions said its partnership with the Perenco Group-owned firm brings more than money to the table. Taranis will leverage its experience in developing and operating large industrial projects — including engineering high-volume processes — to help Circ launch its first industrial-scale blended textile recycling plant.
Dedicated to “sustainable industrial solutions,” Taranis views Circ’s model as a crucial element in the industry’s efforts to make its supply chains less resource-intensive and environmentally intensive. To that end, the carbon circularity company will give the Pyratex partner’s processes “direct technical validation” to fast-track the transition from demonstration-scale to industrial-scale production.
Uluu
Western Australian start-up Uluu snagged $16 million in a series A funding round, as revealed earlier this month.
Specializing in using seaweed to manufacture an alternative to plastic, Uluu will build a demonstration plant to increase production capacity from 100 kilograms to 10 metric tons — representing a 9,900 percent uptick — as it’s essentially the equivalent of 500,000 plastic bottles or 250,000 T-shirts.
Uluu reworks naturally sourced seaweed into an algae-based alternative to synthetics, such as fashion’s material of choice for everything from packaging to panties: polyester (recycled or not). The seaweed start-up has previously likened that pioneering technology to a proprietary process not unlike brewing beer.
“First, we submerse the seaweed in seawater and use special enzymes to extract sugars from the seaweed. These seaweed sugars are then fermented with saltwater microbes that produce polyhydroxyalkanoates —the substance that gives Uluu its plastic-like qualities — inside their cells,” Dr. Julia Reisser, cofounder and co-CEO of Uluu, explained. “To extract the PHAs, we put the microbes in freshwater, causing them to burst open. We then dry the PHAs into a powder, which is used to produce Uluu pellets.”
The company aims to build a commercial facility by 2028 (pending a series B financing round, granted) that could produce thousands of metric tons per year. At that level, Uluu claims it could sequester and avoid up to 5 kilograms of carbon dioxide equivalent (CO₂e) for every kilo of material produced, compared with the roughly 3 kilograms emitted by traditional plastic. In theory, the tech could cut global emissions by more than two billion metric tons a year — theoretically, matching the annual emissions of a country like Brazil or Japan.
The current series A lays the foundation for that growth; Uluu is already working with sector-spanning brands and has previously launched public pilots with partners such as Papinelle and Quiksilver.
“We’re also developing textiles that can replace polyester,” Reisser said. “Working with fashion brands on accessories, such as buttons, is a great way for us to build partnerships ready for textiles in the future.”
Burda Principal Investments (BPI) led the round, with other investors backing the seaweed start-up including Australian deep tech fund Main Sequence and the Hong Kong-headquartered private equity fund Novel Investments, a subsidiary of the textile group Novetex Textiles (both led by Ronna Chao) as well as Aussie accelerator Startmate.
