Choose natural, single-fibre fabrics that can actually be recycled
Blended fabrics are nearly impossible to recycle and quietly shed plastic in every wash. Favouring single-fibre and natural materials makes your clothes last longer, mend more easily and leave a far cleaner end of life.
Most clothes today are a blend — and blends are where textile recycling quietly falls apart. A 60% cotton, 35% polyester, 5% elastane top can’t be unmixed back into clean fibres, so even at a well-run facility it gets downcycled into insulation or rags at best, and landfilled or burned at worst. A garment made of a single fibre, by contrast, can be mechanically broken down and spun into new yarn. Choosing simpler fabrics is one of the few wardrobe decisions that genuinely improves a garment’s end of life.
The everyday payoff comes long before recycling, though. Synthetic blends shed microplastics every time they’re washed — a single load can release hundreds of thousands of tiny plastic fibres that flow straight past treatment plants into rivers and the sea. Natural single fibres don’t. They also tend to breathe better, smell less, and survive mending more gracefully, so they simply last longer in your wardrobe.
This isn’t an absolutist rule. Synthetics earn their keep in waterproofs and proper sportswear, and the greenest garment is always the one you already own — so wear your blends out fully rather than rushing to replace them. But for the steady trickle of new basics, a quick glance at the composition label, and a lean towards one honest fibre, quietly makes your whole wardrobe easier to keep, mend and recycle.
How to do it
- Read the composition label before you buy — it lists every fibre by percentage. Aim for clothes made of one fibre, or as few as possible.
- Favour natural single fibres for the bulk of your wardrobe: 100% cotton, linen, wool, hemp or silk wash, breathe and biodegrade far better than blends.
- Treat synthetics as a tool, not a default. Polyester and nylon earn their place in rainwear and serious sportswear, but they shed microplastics and rarely need to be in a basic tee or jumper.
- Be wary of the elastane trap — even a small percentage (the '5% elastane' in stretch jeans and tops) makes a garment effectively unrecyclable and prone to going baggy.
- Check the feel and weight: a dense, single-fibre fabric tends to wear better and pill less than a thin synthetic blend, so the simpler choice often lasts longer too.
- When you do retire single-fibre clothes, route them to the right stream — wool and cotton are far more likely to be reused or recycled than mystery blends.
Pro tips & pitfalls
- You don't need to bin your blends — wear them out fully first. This is a guide for the *next* thing you buy, not a reason to replace a perfectly good wardrobe.
- Synthetics shed the most plastic in their first few washes and on a fast spin; if a garment must be synthetic, wash it cooler, less often and in a microfibre-catching bag.
What it's good for
Good for the planet
- Saves resources Single-fibre clothes can actually be mechanically recycled into new yarn — blends usually can't be separated, so they're downcycled or landfilled instead.
- Protects nature Natural fibres don't shed microplastics; a single synthetic wash can release hundreds of thousands of plastic fibres into waterways.
- Cuts waste A pure-wool or cotton garment is easier to repair, resell and ultimately recycle, so it stays useful for far longer before it's truly waste.
- Fewer toxins Natural fibres skip the persistent synthetic microfibres that build up in water, soil and — increasingly — our own bodies.
