Why Should You Care About Disposing of Underwear Properly?

Wondering what to do with old underwear? When it’s time to part ways with old underwear, your first instinct might be to toss it in the bin. But did you know that millions of pieces of clothing, including underwear, end up in UK landfills every year?

Disposing of underwear responsibly is a small act that contributes to a larger environmental goal—reducing textile waste, conserving resources, and promoting a more sustainable fashion cycle.

What happens to underwear in landfill?

Underwear, especially those made from synthetic fabrics like nylon or polyester, can take decades to break down in landfill. During decomposition, they release microplastics and toxic chemicals into the environment.

The environmental impact of textile waste in the UK

According to WRAP UK, the average household throws away over 30kg of textiles each year, much of which could be recycled or reused. Underwear often gets overlooked in recycling conversations, but it shouldn’t be.

Can old underwear be recycled like other clothes?

Yes—and no. You can’t usually donate heavily worn or damaged underwear, but textile recycling schemes in the UK do accept underwear, especially if they’re clean and sorted properly. Some pieces may even be repurposed or downcycled into industrial materials.

When Is It Time to Get Rid of Old Underwear?

Underwear doesn’t last forever. While some of your favourites might still feel comfortable, there are a few signs it’s time to let go.

Signs your underwear needs replacing

You should consider parting ways with your underwear if:

• It has holes, rips, or worn-out elastic
• The fabric is stained or discoloured
• It no longer fits properly or causes discomfort
• There’s a persistent odour even after washing

Can damaged or stained underwear still be reused?

Absolutely. Even if your underwear can’t be donated, it can still serve other purposes like household cleaning cloths, pet bedding, or fabric crafts—all of which keep them out of the bin.

What to Do With Old Underwear? 10 Smart, Sustainable Options

Here are 10 useful and eco-conscious ways to deal with your worn-out underwear in the UK.

1. Donate (New or Gently Worn Items Only)

If you have new or barely worn underwear, especially in unopened packaging, many UK charities and shelters will accept them.

Organisations that support refugees, women’s shelters, or the homeless often include underwear in their list of most-needed items.

Always check the donation policy first and ensure items are clean and hygienic.

2. Use Textile Recycling Banks

Textile banks, commonly found in supermarket car parks and recycling centres, accept underwear—even damaged or stained ones—as long as they are clean.

The fabrics are sorted, and unusable pieces are often shredded for insulation, stuffing, or industrial cloths. Look for schemes run by The Salvation Army, TRAID, or your local council.

3. Repurpose as Cleaning Rags or Dust Cloths

Cotton underwear, especially old pants or boxers, can be cut up and used for dusting, polishing shoes, or cleaning glass. It’s a simple way to reduce your paper towel usage and give your clothes a second life.

4. Turn Into Padding or Filling for Pet Beds

Soft cotton underwear can be used as filling for homemade pet beds. Animal shelters sometimes accept clean fabric donations to line cages or make bedding. If you’re crafty, you could even sew your own using old clothes and underwear.

5. Upcycle Into Hair Ties or Craft Projects

The elastic and fabric in your underwear can be repurposed into hair ties, scrunchies, or even quilt patches.

Stretchy materials are ideal for DIY projects, and there are plenty of online tutorials that show how to get creative with minimal tools.

6. Send to a Specialist Recycling Service

If you want to ensure your underwear is disposed of ethically, companies like TerraCycle offer fabric recycling services—even for items most council collections won’t accept.

Some fashion retailers also run take-back schemes, allowing you to return old garments in exchange for store credit.

7. Compost 100% Cotton Underwear

If your underwear is labelled as 100% cotton and doesn’t contain elastic or synthetic dyes, it can be cut into small pieces and composted. Remove waistbands or tags and mix with other compostable material.

This method only works for natural, undyed fabrics, so check the label before tossing it in your compost bin.

8. Reuse the Elastic Bands for Household Fixes

The elastic waistbands can be useful long after the fabric is no good. You can use them to:

• Bundle cables
• Secure loose lids or containers
• Tie up garden plants

It’s a simple form of creative reuse that reduces waste and saves you from buying new household items.

9. Swap or Share in Local Freecycling Groups

Believe it or not, some people collect fabric scraps or use clean underwear for art, fashion school, or upcycling projects. Platforms like Freegle, Olio, or Facebook Marketplace often have users looking for such materials.

Always be clear about the condition and intended use when listing.

10. If All Else Fails, Bin Responsibly

If your underwear is heavily soiled, mouldy, or made of mixed materials that can’t be recycled, then landfill may be your only option. In that case, cut it into smaller pieces to reduce bulk and avoid putting it in public textile bins unless accepted.

Never flush or burn underwear as it can harm plumbing systems or release harmful toxins.

Final Thoughts – Make the Sustainable Choice

Getting rid of underwear doesn’t mean it has to go to waste. By donating, repurposing, or recycling old underwear, you’re helping reduce landfill waste and supporting a more sustainable fashion ecosystem in the UK.

The next time you’re clearing out your drawers, remember—you have more options than just the bin. A little thought goes a long way when it comes to the environment.
