AI, alliances, and ambition: circular fashion hits fast-forward in 2026

By early 2026, AI-powered technologies have emerged as transformative tools in circular fashion, with companies like Synflux and Trosort leading the charge. Synflux’s AI-driven pattern-cutting system reduces textile waste by up to 66% and fabric use by 15%, while Trosort’s AI-powered sorting hardware can digitally identify and sort 1,200 garments per hour, automating resale listings and enhancing circular processes such as reuse, repair, and recycling. These innovations, supported by significant investments—$200,000 for Synflux from PDS and $300,000 from eBay Ventures for Trosort—highlight the critical role of funding and operational support in scaling technological solutions to achieve industry-wide sustainability impact.

Advanced recycling technologies and bio-based materials are redefining the raw material landscape in fashion’s circular economy. MIT spin-out MacroCycle focuses on recycling polyester-rich textiles, while Fibe transforms agricultural waste into natural fibers, illustrating a shift toward sustainable inputs. Complementing these efforts, Hyosung TNC’s $1 billion Vietnam plant produces bio-based spandex from sugarcane-derived materials, showcasing the potential of integrated bio-production systems to replace fossil-based fibers at scale. However, executives emphasize that overcoming price perceptions and securing long-term partnerships remain essential for widespread adoption, underscoring that technological innovation must be coupled with systemic supply chain integration.

Investment in next-generation biodegradable textiles is accelerating, exemplified by Jeff Bezos and Lauren Sánchez Bezos’s $34 million commitment through the Bezos Earth Fund to develop lab-grown fibers from bacteria and agricultural waste. This initiative targets molecular-level transformations aimed at eliminating microplastic pollution and harmful chemicals associated with conventional cotton and polyester, signaling a leap forward in sustainable material science. Such cutting-edge research not only promises to reduce environmental impact but also aligns with broader circular fashion goals by enabling the creation of textiles designed for easier recycling and biodegradation.

While AI-supported sorting technologies significantly enhance the profitability and efficiency of textile sorting facilities, thereby enabling better circular processes, challenges remain in extending garment life through repair and reuse. A 2026 report highlights that repair services are economically viable mainly for higher-value garments, and that the primary barriers to reuse lie not in garment quality—since 37% of donated items show no visible damage—but in the economics of collection, sorting, and resale. This underscores the importance of technological solutions like AI sorting to optimize the supply chain and unlock greater circularity despite inherent economic constraints.

By mid-2026, a coalition of nearly 70 major fashion brands and organizations—including Primark, H&M, Zalando, Vinted, and ThredUp—has united under the Ellen MacArthur Foundation’s leadership to call for decisive policy reforms aimed at dismantling the economic barriers stifling circular fashion. They emphasize that current tax frameworks impose a burdensome 'double taxation' on resale and repair transactions, where items are taxed both at original sale and again upon resale, creating an 'economic trap' that inflates costs and depresses profitability despite soaring consumer demand and a booming secondhand market projected to reach $393 billion by 2030. This coalition advocates for targeted reforms such as reducing or eliminating VAT and sales taxes on resold goods and repair services, lowering labor taxes, and expanding Extended Producer Responsibility (EPR) schemes like California’s SB707 and the EU’s Waste Framework Directive to fund circular infrastructure and operations.

These proposed policy changes are not just about fairness but are projected to unlock substantial economic value, with modeling by the Ellen MacArthur Foundation indicating that gross profit margins could soar to 55% for resale and 41-44% for repair businesses. Such improvements could elevate resale market shares to 12% in the EU and 14% in North America, transforming circular fashion from a niche sustainability effort into a mainstream, profitable segment. However, labor costs remain a stubborn hurdle—accounting for roughly half of repair expenses and a significant portion of resale costs—due to the bespoke, labor-intensive nature of sorting, cleaning, and repairing used garments, underscoring the need for labor tax relief and targeted incentives to scale these models effectively.

Industry leaders stress that harmonized legislation and clear benchmarks defining circularity are critical to providing brands with the clarity and comparability needed to confidently invest in circular business models. Leyla Ertur, Chief Sustainability Officer at H&M Group, highlights the current lack of standardized metrics, stating, 'There’s no way for us to compare apples to apples right now.' Meanwhile, Marianne Gybels of Vinted underscores the essential role of policy in making circular options reliable, affordable, and accessible to consumers, thereby enabling the scaling of climate-friendly alternatives to traditional fashion consumption.

Without swift government intervention to reform tax and regulatory frameworks, the coalition warns that circular fashion risks remaining a niche market despite its rapid growth and consumer enthusiasm. Rachel Kibbe of American Circular Textiles encapsulates this urgency: 'Ending double taxation is not only the fair and just thing to do, it will also spur economic growth and strengthen the trend toward shopping for well-made clothing that can be reused and/or repaired.' This consensus underscores that voluntary business efforts alone cannot overcome the entrenched economic disincentives, making policy action indispensable to unlocking circular fashion’s full economic and environmental potential.

By early 2026, a new wave of startups and platforms emerged as pivotal drivers of circular fashion, blending innovative technology with community engagement to scale sustainable consumption. Depop, recognized in TIME’s TIME100 Most Influential Companies 2026, exemplifies this shift by transforming secondhand clothing into a form of self-expression, making circular fashion culturally relevant through its community-driven marketplace. Similarly, startups like Synflux and Trosort harness AI-powered solutions to drastically reduce textile waste—Synflux’s system cuts waste by up to 66%, while Trosort’s AI hardware sorts 1,200 garments per hour, aiming to eliminate textile landfilling. These innovations, supported by substantial investments such as Synflux’s $200,000 prize from industry leaders and Trosort’s $300,000 funding from eBay Ventures, underscore how technology-driven business models are essential to mainstreaming circularity.

Emerging business models are also redefining circular fashion by creatively repurposing materials and tailoring services to specific markets, demonstrating scalability and cultural resonance. Martan’s upcycling of discarded hotel linens into high-end ready-to-wear collections, supported by Visa’s Recycle the Runway program, highlights how collaborations with recycling specialists like Re&Up foster ecosystem-building critical for scaling circular design. Meanwhile, Vyshlo’s peer-to-peer rental and resale platform targets India’s $50 billion wedding market, integrating features like 'Vyshlo Moments' to track garment reuse and partnering with exclusive designers to elevate circular fashion’s appeal. Vyshlo’s planned expansion into major U.S. cities by late 2026 signals the global potential of such innovative, localized circular business models.

Beyond technology and material innovation, emerging leaders emphasize authentic customer engagement and ecosystem support as vital to embedding circularity into mainstream fashion. Brands like Still Here and Christopher John Rogers stress aligning with consumer values focused on longevity and storytelling to extend product lifecycles, fostering emotional connections that slow fashion’s pace. Programs like eBay’s Circular Fashion Fund not only provide crucial funding—awarding $300,000 to Trosort and $50,000 to other finalists—but also create mentorship and industry exposure, nurturing a collaborative ecosystem where startups, investors, and established companies unite to meet ambitious climate targets. As GFA CEO Federica Marchionni noted, 'adoption and investment are crucial for industry-wide impact,' underscoring the collective effort driving this transformative movement.

By mid-2026, industry collaboration has become a cornerstone for advancing circular fashion, as exemplified by the eBay x Vogue Business dinner where executives from Chanel, Proenza Schouler, Theory, and Revolve gathered to align luxury’s cultural and commercial strategies with circularity. These high-profile events, including the subsequent eBay Fashion Forum, not only foster dialogue but also create a shared vision that integrates sustainability into the luxury sector’s evolving identity, signaling a cultural shift towards authentic engagement with consumers’ growing demand for transparency and extended product lifecycles.

The eBay Fashion Forum and its Circular Fashion Fund illustrate how cross-sector collaboration is operationalizing circularity by uniting innovators, brands, and investors in a dynamic ecosystem. Alexis Hoopes, eBay’s VP and global head of fashion, emphasized the forum’s role in sparking conversations around innovation and circularity, while the 2026 Circular Fashion Fund competition provided emerging businesses like Trosort with critical funding—$300,000 from eBay Ventures—and validation from industry leaders such as Indré Rockefeller and Vogue’s Laird Borrelli-Persson. This model not only accelerates the growth of circular startups but also embeds sustainability as a profitable and scalable business paradigm.
