Why your old clothes are too good for landfill
Every year, millions of tonnes of perfectly wearable clothing ends up buried underground. Here's why keeping garments in circulation is one of the most powerful—and painless—things you can do for the planet.
A Problem Dressed Up as Convenience
It's easy to justify clearing out your wardrobe. A quick bag to the bin, a satisfying feeling of space—and out of sight, out of mind. But the clothes you discard don't simply disappear. The vast majority end up in landfill sites, where synthetic fibres like polyester can take up to 200 years to break down, leaching microplastics and harmful dyes into the soil and water table throughout.
Natural fibres like cotton and wool do decompose, but in the oxygen-starved environment of a landfill, they release methane as they do—a greenhouse gas many times more potent than CO₂. And this is before accounting for the enormous resources already spent making that garment: the water, the land, the energy, the labour.
When we put clothing into landfill, we're not just discarding fabric. We're discarding everything that went into making it.
The Hidden Value in Your Wardrobe
Fashion is one of the world's most resource-intensive industries. A single pair of jeans requires roughly 7,000 litres of water to produce—equivalent to around seven years of drinking water for one person. A wool jumper ties up years of a sheep's grazing and careful husbandry before it ever reaches a shop floor.
That embodied value doesn't evaporate when a garment goes out of fashion or develops a small tear. The materials remain. The craftsmanship remains. With a little care—or simply a change of hands—those resources can continue to be of use.
Circulation Keeps Resources Alive
When clothing stays in circulation—whether through resale, rental, swapping, donation, or repair—its embedded resources keep working. A dress worn by five different people over ten years has a fraction of the environmental footprint of five new dresses made and discarded. The maths is straightforward; the cultural shift is what takes effort.
Secondhand platforms, charity shops, clothing swaps, and repair cafes have all grown considerably in recent years. The stigma once associated with wearing pre-loved clothing has largely dissolved—gone are the days of avoiding ‘stinky’ second hand shops!
Every Garment Has More Than One Life
Even clothes that have seen better days aren't necessarily finished. Worn knees can be patched. Faded fabric can be overdyed. Outgrown children's clothes can be passed along, altered, or turned into something new entirely. The mending and making traditions that were once commonplace are enjoying a real revival—and with good reason. A repaired garment often carries a story that makes it more valuable, not less.
The goal isn't to keep every item forever—it's simply to ensure that nothing ends its life prematurely when it still has something to give. Your old coat, your barely-worn dress, your husband's jacket he never liked: someone, somewhere, will wear them and value them. The landfill won't.
