Only 14.7% Recycled: Use Brand Take-Backs for Period Underwear in the U.S.
If your period underwear is gently used, donate or sell it. If it’s worn out, check for a brand take-back or mail-in program first, since those handle intimate apparel best. Compost only if the piece is 100% natural fiber with no elastic or plastic layers. When none of that fits, prepare it properly and throw it away. Material, hygiene, and possible PFAS content all shape which path actually works, and the steps below walk through each one.
TL;DR:
- Only brand take-back or mail-in programs reliably handle used period underwear due to hygiene and material complexities.
- Composting is feasible only for 100% natural fiber pieces without elastic or synthetic layers, and must be prepared properly.
- Most textiles, including intimate apparel, are difficult to recycle because of blended materials and layered construction, with only 14.7% of textiles recycled nationwide in 2018.
- Extending the lifespan of underwear through proper care delays disposal and reduces waste more effectively than recycling efforts.
- Worn-out underwear should be cut into pieces and discarded in the trash if no suitable donation or recycling option exists.

Where should your old period underwear actually go?
The right path depends on three things: how worn the piece is, what it’s made of, and whether a program exists that will actually take it.
Start with condition. If the underwear is still in decent shape, gently used or unworn, donation or resale is the first option to try. Most shelters and donation centers have strict hygiene rules, though, so check before you box anything up.
- Donate or sell: Many donation centers accept only new, unworn underwear for hygiene reasons, while some accept gently used items if clearly laundered; secondhand marketplaces sometimes allow lightly used intimates with a clear condition description.
- Brand take-back or mail-in recycling: Several brands and retailers run recycling programs specifically for underwear and bras, often through a prepaid mailer, which sidesteps the hygiene issue entirely since the brand controls processing.
- Textile recycling drop-off: Bins and municipal programs sometimes accept underwear, but expect downcycling into insulation, rags, or stuffing rather than new garments.
- Upcycle: Cut worn-out pieces into cleaning rags, use fabric scraps for craft stuffing, or repurpose the elastic bands, though this only works for a fraction of what you’ll retire over time.
- Trash: When nothing else applies, hygiene concerns or mixed materials sometimes leave disposal as the only realistic choice.
Brand take-back programs tend to be the most reliable option for intimate apparel specifically, since they’re built around handling used underwear safely, something most municipal recycling streams were never designed to do.
How to prepare period underwear for donation or recycling
Getting this step right determines whether your donation is accepted or your recycling shipment gets rejected.
- Wash on a hot cycle with a standard detergent, then treat any lingering stains with an enzyme-based stain remover before rewashing.
- Air dry or tumble dry on low. High heat can degrade elastic and absorbent layers faster, which matters if the piece is headed for reuse.
- Cut off tags and, if the program specifies it, remove elastic bands or any metal hardware like clasps.
- For anything going to trash instead of donation, cut the garment into pieces so it can’t be picked up and reused unsanitized.
- Pack items for mail-in programs with any prepaid label provided, and include a brief note listing quantity and condition if the program asks for it.
Pro Tip: Keep a small bag in your laundry area for retired underwear so you’re not scrambling to sort and wash a pile all at once when it’s time to send a batch out.
How brand take-back and mail-in programs actually work
Most take-back programs follow a similar path: you prewash the item, ship it using a provided kit or prepaid label, and the brand or its recycling partner sorts everything by material before mechanical processing. That process typically shreds fibers into insulation, stuffing, or industrial rags rather than turning old underwear into new fabric, since separating blended materials at scale remains limited.
Before sending anything in, it’s worth asking a few questions.
- Where does the brand say the materials actually go, and can it point to a program page describing the process?
- Is the program free, or does it require a fee for shipping or a kit?
- Does the brand specify which materials or product lines it accepts?
You can find these programs through brand websites, the Council for Textile Recycling, TerraCycle brigades such as the Parade Free Recycling Program, or retailer take-back pages. Mail-in is often the only realistic route for intimates because hygiene rules keep most items out of standard donation and curbside bins, so skipping straight to a generic textile bin risks contaminating a load that isn’t equipped to sort it, a habit sometimes called wishcycling.
Can you compost old period underwear?
Only if the piece is 100% natural fiber with nothing else mixed in. Cotton, hemp, and silk can break down in the right conditions, but the elastic bands, absorbent layers, and waterproof PUL lining common in most period underwear cannot, and dyes or synthetic finishes disqualify a garment too.
- Cut the fabric into small pieces to speed decomposition and remove anything that isn’t fabric first.
- Home composting works for small, unlined natural-fiber scraps, but check with municipal or community compost programs before sending anything there, since many won’t accept textiles even when the fiber qualifies.
- Wash the item thoroughly before composting for hygiene reasons.
- If a piece contains any elastic, lining, or synthetic blend, skip composting and choose a take-back program or trash instead.
Why is period underwear so hard to recycle?
Most textiles never make it back into new products. The EPA estimated that only 14.7% of textiles generated in the United States were recycled in 2018, with roughly 2.5 million tons recycled out of 17 million tons generated, meaning the rest ended up in landfills. Just 14.7% of textiles get recycled, and that figure covers all textiles, not just intimates, which face even steeper hygiene and material barriers.
Period underwear compounds the problem with its construction. Layering cotton or bamboo with elastic, PUL, and absorbent synthetic cores makes mechanical separation difficult, so most municipal recycling facilities simply reject mixed-fiber garments rather than attempt to sort them. That’s part of why thrift stores and donation centers are choosy about what they’ll take, and why a curbside textile bin is rarely the right answer for a worn-out pair. The practical takeaway: lean on brand take-back and careful upkeep before assuming any bin will handle the job.
Getting more wear out of what you already own
The single most effective way to cut textile waste is to make what you own last longer, which means the best disposal choice is often the one you delay. A Sierra Club piece on recycling worn underwear points to buying longer-lasting garments and proper care as the most practical levers available to consumers.
- Wash in cold water on a delicate cycle to protect elastic and absorbent layers.
- Use a mild detergent and skip fabric softener, which can coat and weaken absorbent fibers over time.
- Air dry instead of using high heat, which shortens the life of elastic and waterproof linings.
- Watch for thinning fabric, reduced absorbency, or stretched-out elastic as signs it’s time to retire a pair.
Consistent care can meaningfully extend how many wash cycles a pair survives before it needs replacing, which delays the donate-recycle-or-trash decision altogether.

Why care comes before recycling in the waste hierarchy
Recycling feels like the responsible choice, but it’s really the fallback. Extending a garment’s life through good care, then reaching for take-back programs before curbside bins, keeps more fabric out of landfills than recycling ever will on its own. I’d rather see someone wash carefully and skip a replacement cycle than recycle diligently every few months.

FAQ
Why is there a lawsuit against Thinx?
A 2023 class-action settlement addressed allegations of PFAS in Thinx period underwear, leading to a settlement fund and commitments around chemical disclosure. The case pushed broader conversations about chemical transparency across the period underwear industry, a topic we cover in our own PFAS testing background.
What do I do with my period underwear when it’s worn out?
Check whether the brand offers a take-back or mail-in recycling program first, since these are built to handle intimate apparel safely.
Should you throw away or donate old underwear?
Donate only if the piece is new or gently used and clearly laundered, since most donation centers have strict hygiene policies for intimate apparel. Worn-out or stained pieces should go through a brand take-back program or, as a last resort, be cut up and thrown away.
How do I get rid of period underwear responsibly?
Wash and prepare the item, then choose the best available path in order: donate or sell if it’s in good shape, use a brand take-back or mail-in program if one exists, compost it if it’s fully natural fiber, or cut it up and discard it in the trash. This order matters because most textiles, only 14.7% of which get recycled nationally, still end up in landfills without it.
