Mutxamel firm develops biodegradable textile fibers

Textile yarn is usually the boring part of the product — the hidden stuff that just has to be cheap, strong, and predictable. But that is exactly why this Mutxamel project matters. Hilaturas Miel is not pitching a futuristic lab material. It is taking ordinary polyester, which is everywhere in industrial textiles, and trying to fix the part that becomes a waste problem after use. On May 6, 2026, Valencian industry minister Marián Cano visited the company after Ivace+i funded the work with €45,644. ### What did the company actually make? Hilaturas Miel developed a new line of bioactive polyester yarns for the agro-food and meat sectors. The key idea is controlled biodegradation at the end of the product’s useful life — not while it is still doing its job. These yarns are meant for things like fruit and vegetable mesh bags and the textile sleeves used around cured ham and cold meats. ### Why use polyester at all? Because polyester already fits the way these products are made. It is durable, cheap, and easy to run through existing textile machinery. The problem is the same strength that makes it useful also makes it linger as waste. So the company’s move is not “replace polyester with something exotic.” It is more like teaching a familiar material a new final step — stay stable in use, then break down later. That is the hard part. ### How are they making it biodegrade? The project uses microencapsulated enzymes. Basically, the enzymes are packaged so they can survive humidity, temperature swings, and other environmental stress during production and use. That matters because a biodegradable yarn is useless if it starts failing too early. The whole trick is timing — the product has to behave like normal industrial thread until disposal, then begin controlled degradation afterward. ### Why is that technically interesting? Because “biodegradable” on its own is easy to say and hard to engineer. A thread for food-contact or industrial use cannot be fragile, inconsistent, or fussy to manufacture. Hilaturas Miel says the process was validated at industrial scale, with technical viability, repeatable operation, and compatibility with conventional yarn-finishing can actually run. ### Why focus on food textiles? Single-use food-sector textiles add up fast. Mesh for produce and covers for cured meats are small items, but they move in huge volumes and are often hard to recover cleanly after use. That makes them a good target for circular-design tweaks. If the same application can keep its performance but leave less persistent waste behind, the environmental payoff can be bigger than the product looks at first glance. ### Is this a big public investment? Not in raw size. €45,644 is a modest grant. But that is also the point — this is applied industrial R&D, not a moonshot factory build. Ivace+i’s role here looks like a nudge to help a small, established manufacturer test whether a cleaner materials idea can survive real production conditions. Hilaturas Miel itself is not a startup either; the company has been operating since 1983. ### So what changed this week? The news is not that biodegradable fibers were invented from scratch. The news is that a local spinner in Alicante says it has already validated a controlled-biodegradation polyester yarn on industrial lines, for specific commercial uses, with regional backing. That makes the story less about hype and more about manufacturability. ### Bottom line? This is a small materials story, but a practical one. If Hilaturas Miel can keep the cost and performance profile of standard polyester while adding a reliable end-of-life exit, it turns a throwaway textile into something much less stubborn. In industrial materials, that is often how change really happens — not with a miracle fiber, but with a familiar one that finally behaves better when the job is over.
