A new “plastic-eating” enzyme could accelerate textile-to-textile recycling, but scaling it remains the real challenge.
Researchers have developed an advanced enzyme capable of breaking down polyester more efficiently, raising hopes for tackling one of the textile industry’s most persistent circularity problems.
What is new: faster breakdown of synthetic fibres
The innovation centres on a “fusion enzyme” engineered to degrade polyethylene terephthalate (PET), the polymer used in polyester. By combining multiple functional components into a single system, researchers have improved the speed and efficiency of polymer breakdown into its base monomers.
This is significant because polyester dominates global fibre production, yet true fibre-to-fibre recycling remains limited by technical and economic barriers.
Why it matters: circularity needs chemistry, not just collection
Mechanical recycling often degrades fibre quality, while chemical recycling remains costly and energy-intensive. Enzymatic solutions offer a potential middle path—operating under milder conditions and producing higher-quality outputs.
If scalable, such technologies could reduce reliance on virgin petrochemicals and help brands meet tightening regulatory and sustainability targets.
What comes next: from lab promise to industrial proof
The gap between laboratory success and industrial deployment remains wide. Enzyme stability, reaction speed at scale, and integration into existing recycling infrastructure will determine commercial viability.
For now, the breakthrough signals progress—but not yet transformation—in the long pursuit of closing the loop on polyester.
