What clothing made from recycled materials actually is
Most "recycled" clothing in 2026 uses one of three feedstock types:
- rPET (recycled polyester): made from used drinks bottles, melted and spun into yarn. The dominant recycled material in clothing.
- Recycled cotton: mechanically shredded cotton from old garments or factory off-cuts. Limited because shredding shortens fibres.
- Recycled nylon: typically from old fishing nets (Econyl) or carpet fibres.
Fibre-to-fibre recycling, where old clothing becomes new clothing of the same material, remains under 1% of global textile recycling (Ellen MacArthur Foundation 2024). Most "recycled" claims refer to non-textile feedstock (bottles, nets) being processed into textile yarn.

The truth about rPET (recycled polyester)
rPET is the workhorse of the recycled-clothing industry. Process:
- PET drinks bottles collected via kerbside or deposit return
- Sorted, washed, chipped into flakes
- Melted and extruded into fibres
- Spun into yarn for textile use
Real environmental savings vs virgin polyester:
- CO2 emissions: 32% reduction (Textile Exchange 2024)
- Energy use: 59% reduction
- Water use: 90% reduction
The catch: rPET still sheds microplastics during washing (same as virgin polyester). A single wash of rPET fleece can release 700,000 microfibres per WRAP UK 2024 research. The fibres reach waterways and persist in the environment.
Best practice: wash rPET clothing inside a Guppyfriend bag or with a Cora Ball to capture microfibres before drainage.
Recycled cotton - why so little exists
Mechanical cotton recycling shreds old cotton garments into fibres. Two technical limits:
- Fibre length: shredding cuts fibres to 5-15mm, well below the 25-35mm needed for new yarn production. Recycled cotton usually mixes 20-30% recycled with 70-80% virgin cotton.
- Colour mixing: shredded cotton from mixed colours produces grey-brown blends, limiting design options.
Chemical recycling (Renewcell, Worn Again Technologies, Infinited Fiber) preserves fibre length and produces virgin-equivalent material but remains under 1% of global textile output. Commercial scale-up is expected 2027-2030.
Recycled nylon - Econyl and alternatives
Econyl is the dominant recycled nylon brand, made by Aquafil:
- Feedstock: discarded fishing nets, carpet fibres, industrial nylon waste
- Process: regeneration produces nylon yarn identical to virgin in quality
- Brands using: Stella McCartney, Prada Re-Nylon, Burberry, Adidas, Outdoor Voices
- CO2 saving: 90% reduction vs virgin nylon production
Alternative recycled nylon brands: Repreve (Unifi), Sea2See (specific to ocean plastic). All deliver similar environmental savings.
How to verify recycled-content claims
Certifications that mean something:
- GRS (Global Recycled Standard): at least 50% recycled content, full supply chain audit
- RCS (Recycled Claim Standard): at least 5% recycled content, lower audit requirement
- OEKO-TEX RECYCLED: combines recycled content + safety testing
- bluesign: end-to-end sustainability standard (includes recycled content tracking)
Claims without certification ("made with recycled materials") are not legally enforceable in most jurisdictions and often unverifiable.
The UK CMA Green Claims Code (September 2021) and US FTC Green Guides both require recycled-content claims to be specific and verifiable. Enforcement actions against vague claims have increased through 2024.
What to look for when buying
Three rules for choosing recycled-content clothing:
1. Look for stated percentage
"100% recycled polyester" is meaningful. "Made with recycled materials" is not. Genuine brands disclose percentages on the label or product page.
2. Look for certification
GRS or RCS certification adds verification. Brand-only claims without third-party audit are weaker.
3. Consider end-of-life
Garments made of single-fibre recycled materials (100% rPET, 100% Econyl) can themselves be recycled at end of life. Mixed-fibre garments (60% rPET + 40% organic cotton) are much harder to recycle. Single-fibre is the better long-term sustainability choice.
Honest pricing comparison
Recycled-content clothing typically costs 10-40% more than virgin equivalents:
| Product type | Virgin polyester | Recycled polyester | Premium |
|---|
| Plain T-shirt | £8-£12 | £12-£20 | 35-50% |
| Running shorts | £15-£25 | £22-£35 | 40-50% |
| Fleece jacket | £30-£50 | £45-£75 | 50% |
| Leggings | £20-£35 | £35-£68 | 75-95% |
| Swimwear | £25-£40 | £45-£85 | 80-110% |
Premium-brand recycled materials (Patagonia, Outerknown) carry larger premiums than mass-market equivalents (H&M Conscious, Uniqlo HEATTECH).
Greenwashing watch-outs
Common misleading claims to watch for:
- "Made with recycled materials" with no percentage = often <5% by weight
- "Eco-friendly" without certification = marketing buzzword only
- "Sustainable" without specifics = meaningless
- "Made from ocean plastic" without verification = unverifiable supply chain
- "Plant-based" = often refers to a small percentage of natural fibre in synthetic blend
The Changing Markets Foundation has tracked 18 major fashion brands' sustainability claims through 2024; 11 made claims that did not survive independent audit.

Frequently Asked Questions
What clothing brands actually use recycled materials?
Patagonia (87% recycled materials by weight 2024), Girlfriend Collective (100% recycled polyester and nylon), Outerknown (90% recycled or organic by 2024), Adidas Parley (100% ocean plastic Parley range), and Eileen Fisher Renew lead the field. Mass-market: H&M Conscious Collection and Uniqlo HEATTECH offer 50-100% recycled materials in select lines.
What is rPET clothing made from?
rPET (recycled polyester) is made from used plastic drinks bottles. The process: bottles are collected, sorted, washed, chipped into flakes, melted, extruded into fibres, and spun into yarn. Production saves 32% CO2, 59% energy, and 90% water vs virgin polyester per Textile Exchange 2024 figures.
Is recycled clothing actually better for the environment?
Yes, with caveats. Recycled polyester cuts CO2 by 32% and water use by 90% vs virgin polyester. However, it still sheds microplastics during washing (700,000 microfibres per wash for rPET fleece, per WRAP UK 2024). Use a Guppyfriend bag or Cora Ball when washing synthetic recycled clothing.
How can I tell if a 'recycled' claim is real?
Look for certifications: GRS (Global Recycled Standard, requires 50%+ recycled content + supply chain audit), RCS (Recycled Claim Standard, 5%+ content), OEKO-TEX RECYCLED, or bluesign. Vague claims like 'made with recycled materials' without a stated percentage or certification are often under 5% by weight.
Why does recycled clothing cost more than regular?
Recycled feedstock processing (bottle collection, sorting, washing, chipping) adds 10-40% to manufacturing cost vs virgin polyester. Premium brand-specific premiums (Patagonia, Outerknown) reflect their higher overall quality and certification overhead. Mass-market recycled (H&M Conscious, Uniqlo) is closer to virgin pricing.
