Challenges Affecting Textile Recycling Quality

STUDY FINDS JUST 2% OF DANISH TEXTILES ARE FIT FOR HIGH QUALITY RECYCLING: A new study by the Technical University of Denmark examined more than 4,400 garments. It found that complex blends, hidden linings and zips, buttons and trims (“disruptors”) are blocking the path to a circular textile economy. The research, based on the Nordic Textile Anatomy Database, reveals: - 618 different fibre blends in one season, making recycling calibration challenging - Disruptors present in over half of garments, often requiring labour-intensive removal - Polyester dominates global production but is rarely found in pure form in garments, limiting recycling options When global fibre production data was used, around 20% of textiles looked recyclable. But factoring in actual garment anatomy slashed that to 11%, with less than 2% suitable for fibre-to-fibre recycling at the highest quality. The authors conclude that collection alone won’t meet EU circularity targets. #TextileRecycling #SustainableFashion #WasteManagement

Here are my reflections from the August Supplier Meet-Up hosted by the Asia Garment Hub. Each month, one supplier shares a specific challenge they’re facing while the rest of the group shares feedback and offers support. The challenge presented this month related to waste management. The supplier in question wants to recycle its fabric waste but is facing a number of infrastructural, legal, political, and economic barriers. For example, recycling infrastructure in their country is virtually non-existent. Furthermore, the country’s waste management services are monopolized by a small group of companies with close ties to the government – and have a vested interest in the status quo. The supplier noted that, as a result, there is little political appetite for developing recycling infrastructure.  Legally, the supplier also faces barriers to recycling its textile waste. They have a license from the government to import fabrics duty-free (because fabrics are not produced locally). These licenses are designed to attract foreign investment into the country. Maintaining the license requires being able to prove that all imported textile has been exported as a finished product.  This has two practical consequences for the factory: First, they cannot export their scrap to countries with better recycling infrastructure - because they can only export finished goods. Indeed, the factory must prove that the variance between the kilos of fabric imported and the kilos of fabric used in exported finished goods has been collected by a waste management company.   Second, although the factory could hypothetically use its scraps to create new finished goods, the factory doubted that they would be able to find international buyers willing to pay the price. The supplier also noted that, even if they were able to resolve their legal barriers and could export their scrap to countries with better recycling infrastructure, some of their neighboring countries have bans on importing waste.  The supplier sharing their challenge asked the group whether any participants had successfully raised this issue with their buyers. One participant responded that their buyers were, in principle, open to supporting circularity initiatives and that they had more recycling options available in their context. However, they also shared that many of their customers wanted fabrics made with waste coming from their own products (not waste from other brands’ products). They noted that this was practically impossible, and a level of commitment that most brands were unable or unwilling to give.  The conversation closed with a discussion about how poorly the systemic barriers to recycling tend to be understood.

I recently came across an interesting piece of academic research that I think will be of interest to anyone working in clothing design, product development, recycling, or policy. The paper, "Assessing the circularity potential of textile flows for future markets in Denmark: A study of textile anatomy" by Heather Logan et al (DTU - Technical University of Denmark), looks closely at how the design of garments impacts their recyclability at end of life. https://lnkd.in/eAyrrSq2 Key takeaways from the study: 1) The researchers examined the physical make-up of garments—things like zips, buttons, linings, and fibre blends (“textile anatomy”). 2) Under current systems and technologies, less than 2% of garments analysed were suitable for high-quality recycling. 3) The biggest barriers were complex construction and mixed materials that are difficult to disassemble and process. The study also makes clear that this figure is not fixed — with changes in design, adoption of automated sorting/disassembly, and expansion of fibre separation and recycling infrastructure, this percentage could rise dramatically. In short, collection alone won’t deliver circularity — design choices at the start of a garment’s life will determine how recyclable it is at the end. For those in the industry, this is a reminder that product design decisions today directly affect recycling outcomes tomorrow. Worth a read if you’re interested in designing for recycling: What are your thoughts — how can we better balance design creativity with end-of-life recyclability? #TextileRecycling #CircularEconomy #DesignForRecycling #SustainableFashion #EcoDesign #TextileCircularity

Recycled polyester is everywhere — but so is the liability. A review of the 2025 textile supply-chain landscape points to a growing vulnerability in fashion’s most widely used sustainability claim: Data Integrity. Public industry data indicates that while a large majority of brands plan to increase recycled polyester (rPET) use, the overwhelming share of feedstock still originates from plastic bottles, not post-consumer textiles. Textile-to-textile recycling remains limited to pilot scale. Meanwhile, bottle-based recycling has been industrialised. This is no longer just an environmental debate. It is a compliance and financial risk. EU policy is swiftly moving sustainability claims from voluntary marketing language to legally substantiated disclosure. Under the Ecodesign for Sustainable Products Regulation (ESPR) and the Green Claims Directive, generic “recycled” claims without verifiable origin data will not hold. Three pressure points are now converging: - The Data Blind Spot: Many LCAs still rely on secondary industry averages rather than primary, site-specific tier-1/tier-2 data. This weakens claim robustness before regulators. - The Reporting Risk: Variations in feedstock attribution can materially affect reported Scope 3 emissions, creating volatility in carbon disclosures. - The Material Trade-off: Peer-reviewed research indicates mechanically recycled polyester fibers are shorter and more brittle, with studies suggesting significantly higher microfiber shedding rates (+55%) compared to virgin polyester. Taken together, these factors shift traceability from a sustainability function to a CFO-level risk question. Brands that treat recycled-content claims as a checkbox will face rising compliance costs and audit friction. Brands that invest early in verified chain-of-custody and primary data capture will convert transparency into operational resilience. The bottom line: If you cannot digitally verify the origin and flow of your recycled fiber, you don’t have a sustainability strategy. You have a marketing risk. Where do you see the largest data blind spot in your supply chain today — feedstock verification (proving it’s not just bottles) or Tier-2 processing visibility? 👇 Let’s discuss in the comments.

One of the biggest barriers to textile circularity has been the presence of elastane (spandex) in garments. Even at very small percentages, elastane can render an entire fabric unrecyclable — leading to massive global waste streams that we currently send to landfill or incineration. But research released by BiofluidsLab @TUWien is showing promising progress: new methods can detect and separate elastane from the other fibers without degrading fiber quality. This means blended stretch textiles — previously considered unrecoverable — may soon have viable recycling pathways. As someone who has spent my career working with activewear, performance knits, stretch fabrics, and technical blends, I view this as a meaningful step toward solving one of the hardest problems in apparel sustainability. If elastane can be selectively separated and removed, suddenly: stretch denim becomes recyclable leggings become recyclable swimwear becomes recyclable performance knits become recyclable athleisure becomes recyclable And this brings us closer to a future where material circularity is not just theoretical — but operational. To anyone working in apparel recycling, material science, or circular design — I would welcome a conversation. We are finally seeing solutions that could redefine material responsibility in the textile industry. #TextileRecycling #Circularity #Elastane #MaterialInnovation #StretchFabrics #SustainableFashion #PerformanceTextiles #FutureOfApparel #eavolu #EarthFirstConsultants #SustainableManufacturing

Europe’s textile waste could fill c.80 football stadiums each year, over the decade. By 2035, post-consumer textile waste in Europe is projected to reach ~18Mt annually, up from ~13Mt today (+36%). Less than 1% is recycled back into new textiles. Most textiles never reach recycling. They are lost early in the system through low collection rates, limited sorting depth, and infrastructure that was not built to separate materials at the level required for recycling. What reaches recyclers is often inconsistent, contaminated, or too fragmented to process efficiently. At the same time, recycled fibers remain structurally more expensive than virgin alternatives. Chemical recycling is capital intensive. Pre-processing requires additional steps. Energy and operational costs are higher. Recyclers operate with negative margins, while brands work within tight cost structures and short product cycles. This creates a structural disconnect across the value chain. Three shifts start to make this investable: • Collection moves from optional to systematic Dedicated collection channels, in-store take-back, and EPR-funded systems increase capture rates and reduce contamination at source • Sorting evolves into an industrial capability Advanced sorting technologies, fiber identification, and standardized grading create consistent, recycling-ready feedstock at scale • Pre-processing and recycling scale together Investment in cleaning, shredding, and material preparation aligned with recycling capacity improves yields and reduces downstream costs • Demand is secured, not assumed Long-term offtake agreements, minimum recycled content requirements, and pricing mechanisms that reflect true end-of-life costs create predictable revenue streams • Risk is shared across the system CAPEX support, guarantees, and coordinated policy frameworks reduce first-mover risk and enable early infrastructure build-out Without these shifts, the system continues to expand in volume while losing material, value, and economic viability upstream.

Did you know only 1% of clothes are recycled into new clothing? While negative recycling headlines are abound for certain materials (ex. plastics), this figure caught my eye. I'm learning more about textile-to-textile recycling, and wanted to share some tl;dr: What it is: Transforming used textiles directly back into new fibers for clothing production. Why it matters: This minimizes virgin resource extraction, reduces pollution, and keeps clothing out of landfills. It also is one of those "feel good" applications of a certain material kept in the same The catch: Not all textiles are suitable. Natural fibers are easier to recycle mechanically, while blends pose a challenge. The Environmental Urgency: 🟢 The textile industry accounts for around 10% of global greenhouse gas emissions. 🟢 An estimated 85% of textiles end up in landfills, a major source of greenhouse gas emissions. 🟢 Producing virgin textiles consumes vast amounts of water and energy - ex. It takes approximately 2,700 liters of water to produce a single cotton t-shirt – enough to supply one person's drinking water needs for 2.5 years. Recycling Potential: 🔵  Studies like the one below suggest that substituting recycled fibers for virgin materials could significantly reduce carbon emissions within the fashion industry. 🔵  Textile-to-textile recycling lessens the reliance on land and resources for new fiber production - with up to 80% less carbon emissions Transitioning to Challenges: 🟡 Mixed Fibers: Modern garments often contain complex blends, making separation for high-quality recycling difficult. 🟡 Infrastructure Shortfall: The US lacks the systems to collect, sort, and process our massive textile waste stream efficiently. 🟡  Economic Competition: Recycled fibers can struggle to compete with low-cost virgin materials. So, where do we go from here? ➡️ Design for Circularity: Products designed for easy disassembly and fiber recovery are crucial. This has to go hand in hand with scaling infrastructure investment / value chains to accommodate textile recycling. ➡️ Continue to invest in R+D: We need innovations in sorting, handling mixed fibers, and ensuring the quality of recycled output. ➡️ Support better policy: Incentives, regulations, and extended producer responsibility could level the playing field for recycled materials. ➡️  Shop with sustainability in mind: Demand for products with recycled content drives market change. https://lnkd.in/giy-dwnJ #circulareconomy #textilewaste #fashionindustry #sustainability #recycling #innovation

Another peer-reviewed study confirms what an increasing number of researchers have been warning for years: Mechanically recycled polyester releases more microplastic fibers than virgin polyester — and the problem intensifies with repeated recycling cycles. In this work, fabrics containing mechanically recycled polyester were subjected to one, two, and three recycling loops. The results are unambiguous. While a single recycling cycle may appear “acceptable” under current testing regimes, second and third recycling cycles resulted in up to a 4–6 fold increase in microfiber emissions compared to virgin polyester. mechanically-recycled-textiles-a-source-of-microplastic-fiber-emissions.pdf None This is not an isolated finding. It is not “one or two studies.” It is a pattern that is now well established across the literature: mechanical recycling degrades fiber integrity, increases yarn hairiness, accelerates fragmentation, and ultimately amplifies microplastic pollution. Even more critically, the study shows that high microfiber release persists across multiple recycling cycles, rather than declining. This is a clear signal that the issue is systemic, not transitional. The idea that “we just need to recycle more times to close the loop” collapses under empirical evidence. Perhaps most concerning from a regulatory perspective is this: 👉 Dry abrasion (real-world wear) generates substantially more microfiber emissions than laundering, yet policy and standardization efforts continue to focus almost exclusively on washing-machine-based assessments. This means we are likely underestimating emissions by design, while simultaneously promoting recycled textiles as an environmental solution. So let’s be clear: ♻️ Recycling, as it is currently implemented for synthetic textiles, is not a solution to microplastic pollution. At best, it is a partial waste-management strategy. At worst, it externalizes a different environmental cost — one that enters air, water, soils, food webs, and human bodies. If textile circularity policies do not explicitly account for microfiber release across the full life cycle, they risk becoming green narratives rather than evidence-based interventions. The question is no longer “Should we recycle?” The question is “How much environmental harm are we willing to ignore in the name of circularity?” https://lnkd.in/dyBSqeHU

The Future of Circular Fashion: Key Insights from Cleantech Group's 2024 Textile Recycling Insight The textile industry faces a significant challenge: Waste. Less than 1% of new textiles used recycled fibers according to TOMRA. Beyond recycling, textile waste generates ~6% of landfill volume, 10% of global emissions, and 20% of global water pollution. The industry is filthy and requires substantial reforms at nearly every level: policy, manufacturing, and waste management included. Here is where I see hope: The Opportunity: Fiber-to-fiber recycling could recycle 28-40 million tons of textile waste by 2030, while open-loop recycling could handle another 11-17 million tons. •Key Technologies: Several technology niches are emerging: ◦Mechanical Recycling: (TRL 9) Promising for animal fibers. ◦Solvent Dissolution: (TRL 5/6) The most promising technology for mixed cotton/polyester blends. Worn Again Technologies is a very relevant name here. ◦Depolymerization: (TRL 6/7) Very promising for nylon or near-pure polyester. Syre, Reju, and JEPLAN, INC. all have projects here. ◦Pulping: (TRL 7) A great option for cotton. ◦Enzymatic Depolymerization: Superb fit for nylon recycling. Companies like Samsara Eco and Carbios are leaders. •Challenges: ◦Sorting: Inefficient sorting of blended textiles limits recycling. Chemical composition software like Sixone Labs' radically changes the outlook on mixed waste recyclability. ◦Feedstock: Low collection rates and lack of high-purity feedstock hinder recycling efficiency. ◦Economics: Even the most efficiently recycled fibers remain 10%+ more expensive than virgin options. •Drivers: ◦Policy: Aggressive policy mandates, like Extended Producer Responsibility (EPR), are essential for a thriving recycling ecosystem. ◦Investment: Investment in solvent dissolution and depolymerization is growing. ◦Industry Partnerships: Fashion brands like H&M, lululemon, Patagonia, and Zara are investing in recycling technologies and forming partnerships, offtake agreements with innovators. •Regional Activity: ◦Europe: Leading in collection, with Germany at 75.6%, and policy, with the EU Strategy for Sustainable and Circular Textiles. ◦United States: Focusing on public and private partnerships to scale up facilities including LASAN facility in Los Angeles. California is a compelling market. ◦China: Goals to recycle 30% of waste textiles per year by 2030. ◦India: Investing billions of dollars in circular textile recycling/manufacturing. •Key Players: ◦WM: Partnering to improve sorting and supply high-purity waste. ◦Goodwill Industries International: Partnering with WM and Reju for textile feedstock supply. ◦Eastman: Developing chemical recycling facilities for polyester. ◦Debrand: Focusing on textile logistics and sorting. All that said, these innovations are useless without building out recycling or recycled content use in textile manufacturing concentrated in Asia. Blog here:

Who is Failing the Textile Recycling Industry? 🤔 A few years ago, the fashion world woke up to a PR crisis: 📸 pictures of their clothes ending up in deserts of Chile 🏜️ or beaches of Africa 🏖️. This brought the conversation around responsibly managing textile waste to the centre. ♻️ The answer seemed obvious: recycle it. And yet… today, more than 85% of textile waste still ends up burned or buried. I’ve spoken to hundreds of stakeholders across the system — brands, recyclers, waste handlers, designers. And the truth is: everyone wants to recycle. But the system is failing by its own structure. 1️⃣ The brands & manufacturers want to “go circular”… …but their product team is still designing products with five materials, glues, and chemicals. Not because they want to make recycling hard — but because no one told them it mattered. By the time that product is tossed out, it's too late. No one can untangle it. 2️⃣ The collector does their job. They gather tonnes of discarded textiles — but they’ve been trained to look for resale value, not recyclability. The cotton jeans go in the same bag as the sequined tops and the carpets. To a recycler, that’s not feedstock. It’s chaos. 3️⃣The recycler? They’re ready. They’ve built the infrastructure. But they don’t communicate with collectors. They treat their sourcing guidelines as classified information. And right now, they’re receiving bales of unknown fabric types with no digital trail, no fibre breakdown, and no viable way to scale. 4️⃣ And what about governments? They regulate packaging. They tax plastic bags. But textiles? Still considered a "soft problem." The policy is lagging. The funding is thin. The urgency is missing. So we keep going in circles, chasing a vision of circularity — without building the roads to get there. But there’s a different path. 🌱 And we’re already building it. 👋 At Eslando, our marketplace connects the dots 🔗 — between collectors, recyclers, brands, and sorting innovators. Because recycling isn’t magic ✨. It’s infrastructure 🏗️. It’s data 📊. It’s cooperation🤝.
