Enzymatic recycling of clothes is no longer a university lab experiment. Enzymes designed with the help of artificial intelligence are now breaking old nylon and polyester garments down into their original building blocks, which are then rebuilt into new yarn of virgin quality. At the centre of this story is an Australian start-up, Samsara Eco, and a sportswear brand anyone who works with technical fabrics knows well: lululemon.
Why should this matter to you as a designer? Because, according to third-party research cited by Samsara Eco, less than 1% of textiles worldwide are recycled into new textiles today. Most of what we design ends up in landfill or incineration. Enzymatic recycling is one of the few solutions that could change that.
What Is Enzymatic Recycling of Clothes?
Picture a synthetic fibre as a long string of linked beads. Traditional mechanical recycling shreds fabric and re-spins it, so the string gets shorter and weaker with every cycle — which is why mechanically recycled fabric usually ends up as stuffing or insulation. An enzyme works more like a very precise pair of scissors: it unclips the beads one by one until the polymer is back to its “monomers”, its original units. Through enzymatic recycling, new nylon or polyester is then built from those units that is identical to virgin material and can be recycled again and again.
This is where AI comes into enzymatic recycling. Natural enzymes don’t “eat” plastic efficiently, so Samsara Eco uses an AI-powered enzyme discovery platform that simulates thousands of variations of an enzyme and picks the ones that survive factory conditions and work on a specific type of fibre.
What this means for you: the fabric you choose today will be the raw material for the next production cycle. Knowing a fibre’s composition is no longer a technical detail — it is part of the design itself.
Why Nylon 6,6 Was Such a Hard Problem
Nylon 6,6 is one of the most widely used nylons in sportswear and outerwear, with around 4 million tonnes produced every year. It is the core fibre in lululemon’s best-known leggings, such as Align and Wunder Train. Its strength and toughness are exactly why it is so popular — and exactly why it is so hard to recycle, especially when blended with elastane.
In February 2024 the two companies announced the world’s first enzymatically recycled nylon 6,6 product: samples of the Swiftly Tech Long-Sleeve Top, in which more than 90% of the nylon came from Samsara Eco’s process, with the same fit, feel and quality. Note the word “samples”: this top was not put on sale; it was proof that the technology works.
What this means for you: if you design activewear or swimwear, recycled nylon with virgin-level quality means you no longer have to choose between performance and sustainability.
From Sample to Store: the Packable Anorak
The first commercial step for enzymatic recycling came in April 2024, when lululemon launched the limited-edition Packable Anorak, its first product made with enzymatically recycled polyester. It was made from mixed plastic waste, end-of-life lululemon apparel and carbon emissions converted by LanzaTech’s technology, and sold online in Australia, the US and Canada.
What this means for you: an old garment has become the source of new fabric. That idea could become a powerful marketing story for any small label that collects old pieces back from its customers.
A Ten-Year Deal and the Jerrabomberra Plant
In June 2025 the partnership became a long-term commitment: a 10-year offtake agreement under which Samsara Eco’s materials could cover around 20% of lululemon’s fibre portfolio by 2030. That matters because polyester and nylon alone make up roughly two-thirds of the fibres the brand uses.
Three months later, in September 2025, Samsara Eco opened its first plant in Jerrabomberra, Australia, with capacity equivalent to hundreds of thousands of garments a year. The site also hosts research with The LYCRA Company on recycling spandex, and paves the way for a 20,000-tonne commercial nylon 6,6 plant in Asia, planned for 2028.
What this means for you: terms like “enzymatically recycled” and “virgin-identical” will soon appear in supplier catalogues. A designer who understands them can ask the right questions and negotiate for a fabric with guaranteed performance.
Protein Evolution and Stella McCartney: the Same Path in Luxury
Samsara Eco is not alone in the race for enzymatic recycling. US company Protein Evolution has developed a technology called Biopure that also relies on AI-designed enzymes to break down polyester. Working with designer Stella McCartney, who tested the technology on leftover fabrics from her past collections, it presented a parka at the COP28 climate conference in December 2023 whose polyester was made from packaging waste and industrial freight straps.
What this means for you: enzymatic recycling isn’t limited to sportswear. Luxury fashion is adopting it too, and the cutting-room offcuts in your own studio could one day become a valuable raw material.
How to Prepare as a Designer for the Age of Enzymatic Recycling
- Design with a single material where you can: a garment made from one fibre is far easier to break down than one combining three. See also our article on blended fabric recycling.
- Watch out for elastane: it is still the biggest barrier in stretch fabrics, as we explained in Elastane Recycling.
- Ask your supplier: is this fabric mechanically, chemically or enzymatically recycled? The answer shapes performance and price.
- Think about the end of the garment’s life: removable buttons, zips and labels make it easier for a piece to reach a recycling plant.
Conclusion
In three years, enzymatic recycling of clothes has moved from a sample top to a jacket in stores, then to a ten-year deal and a real plant. There is still a long way to go: the large commercial plant won’t open before 2028, and cost and scale remain the real challenge. But the direction is clear — designers who understand material from fibre to finished garment will be best prepared for this future. At Anna Stella Academy, we see understanding fabrics and materials as a foundation of every fashion designer’s journey.
