Can You Recycle Underwear? - Sometimes Guide (2026)

Last updated: 27 April 2026

Quick Answer

⚠ Sometimes - depends on type and local programme. Underwear in good condition can be donated to specific charities (Smalls for All accepts new underwear donations). Worn underwear goes to textile recycling for fibre.

Where to recycle underwear

The fastest way to find recycling for underwear near you:

Use the eCycling Central recycling locator: /tools/recycling-locator - filter by waste type
Check the Top 50 US Electronics Recyclers for major operators
Local council websites maintain up-to-date drop-off lists for non-electronic household waste

What's involved

Underwear in good condition can be donated to specific charities (Smalls for All accepts new underwear donations). Worn underwear goes to textile recycling for fibre.

Special handling and hazards

Some councils have specific bins for unwearable textiles (the H&M takeback accepts any condition).

If you live in the United States, household hazardous waste (HHW) collection days are operated by every county - check your local solid waste authority for the next scheduled date. UK residents: check your council's bulky-waste collection rules.

What happens to recycled underwear

When underwear enters the proper recycling stream, the materials follow this path:

Aggregation at a Material Recovery Facility (MRF) or specialist processor
Sorting by composition - automated for high-volume streams (paper, plastic), manual for low-volume specialist streams
Cleaning and processing - shredding, washing, melting, or chemical separation as the material requires
Re-introduction to manufacturing - new products, packaging, infrastructure materials

For underwear specifically, the recycled material typically becomes new consumer products in the same category, or is downcycled into industrial-grade applications (insulation, building aggregates, road surfacing).

Environmental impact of throwing underwear in the trash

When underwear ends up in landfill instead of recycling:

The material is permanently removed from the circular economy
Landfill space is consumed - estimated at $30-80 per tonne in disposal costs that taxpayers fund
Methane and CO2 are released as the material decomposes (or never decomposes, in the case of plastic and glass)

For perspective, the United States generates approximately 292 million tonnes of municipal solid waste per year (EPA 2024). Items like underwear make up a measurable percentage of this stream and represent low-hanging fruit for reducing landfill volume.

Reuse options before recycling

Before sending underwear to recycling, consider:

Donation if the item is intact and functional (charity shops, Freecycle, Facebook Marketplace)
Repair if practical - the second-hand value may exceed the recycling value
Repurpose for a different use (storage, craft material, garden use)
Sell to specialist secondhand buyers if value is high enough

The waste hierarchy (defined in the EU Waste Framework Directive 2008/98/EC and broadly mirrored in US state law) ranks reuse above recycling for environmental and economic reasons.

What about composting?

Composting is not appropriate for underwear - the material does not break down under typical composting conditions and may contain non-organic contaminants.

Frequently asked questions

Can I put underwear in my regular recycling bin? Sometimes - it depends on the specific type and your local programme. Check your council/municipality recycling guidelines.

Are there manufacturer or retailer takeback programmes for underwear? Underwear in good condition can be donated to specific charities (Smalls for All accepts new underwear donations). Worn underwear goes to textile recycling for fibre.

Is underwear curbside-recyclable in the UK? UK curbside collection rules vary by council (363 different schemes). The general guidance for underwear is the same as the US answer above, but check your specific council's recycling A-Z guide for definitive local rules. WRAP UK (the Waste and Resources Action Programme) maintains national guidance at recyclenow.com.

Can I recycle underwear in California specifically? California has the strictest e-waste and recycling laws in the US (see California Electronics Recycling Law 2026). The general answer above applies, with stricter enforcement and broader collection infrastructure.
