Recycled fabrics without the greenwash: an honest guide for brands and promo buyers

A quiet deadline is about to reorganise sustainable-apparel marketing: from 27 September 2026, EU consumer law bans generic environmental claims — “eco-friendly,” “green,” “sustainable” — unless backed by recognised proof, with offset-based “carbon neutral” product claims banned outright. The psychology of the market flips overnight: for years, vague virtue was free and specifics were work. Now vague virtue is a legal liability, and documented specifics are the only claims left standing. Here’s what that means for recycled fabrics, told honestly — including the parts the hangtags leave out.

What recycled polyester actually is

About 98% of recycled polyester comes from plastic bottles, mechanically shredded, melted and re-spun; it made up roughly 12% of all polyester in 2024. For knitwear — fleece, tees, uniforms — good bottle-grade rPET performs close to virgin, at a fibre-level premium of very roughly 10–25%, a gap that widens whenever oil is cheap. Chemical recycling (back to virgin-grade monomers) and true textile-to-textile recycling exist but remain small — textile-to-textile is only about 2% of rPET. That’s the real landscape; anyone selling it as a closed circle is selling.

The honest problems — which you should hear from your supplier first

• Polyester sheds microfibres, recycled or not — and research suggests mechanically recycled fibre can shed <strong>more</strong>, because shorter polymer chains break more easily.
• Bottle-to-fibre is criticised as downcycling: it pulls bottles out of bottle-to-bottle loops, and the garments made from them are rarely recyclable again.
• Recycled cotton is real but limited: mechanical recycling shortens the fibre, so quality yarns cap at roughly <strong>20–30% recycled content</strong>, mostly from clean post-industrial waste.

None of this means “don’t use recycled.” It means recycled content is a genuine, bounded improvement — not an absolution — and buyers who describe it that way will never be caught overclaiming.

The fraud problem nobody puts on a hangtag

Recycled and virgin polyester are chemically near-identical — which, combined with the price premium, created predictable results: an 18-month testing investigation published in 2022 found 62% of products claiming recycled polyester didn’t contain the claimed amount — or any at all. You cannot see the difference, and neither can your customer. The only protections are laboratory testing and an unbroken, certified chain of custody. Which brings us to what the certificates actually do.

GRS and transaction certificates: what covers what

The Global Recycled Standard requires at least 20% recycled content to certify (50% to carry the consumer-facing label) and adds chemical, environmental, and social criteria at certified sites. The machinery that makes it trustworthy: every company that owns or processes the material — recycler, spinner, knitter, dyer, sewing factory — holds a scope certificate, and every shipment between them travels with a transaction certificate issued by the certifier. The chain is the claim.

And here is our own position, stated the way we wish more factories would: we can source GRS-certified recycled fabrics from certified mills, with transaction certificates covering the fabric into our hands — meaning you can truthfully say “made from GRS-certified recycled fabric.” For the finished garment to carry GRS certification and logo, the sewing factory itself must be certified — we aren’t today; it costs a few thousand dollars and is on our roadmap the day a buyer’s programme needs it. If a supplier can’t explain this distinction to you, they don’t understand the claim they’re selling.

Why buyers are asking now

• The EU’s generic-claims ban applies from <strong>September 2026</strong> — specific, certified claims are what survive it.
• France literally pays for recycled content: the textile EPR scheme grants eco-modulation bonuses of <strong>€500–1,000 per tonne</strong> for recycled material. <a href="/blog/nepal-knitwear-sourcing-france-buyers-guide/">Our France guide covers it.</a>
• Corporate sustainability reporting pulls purchased goods — uniforms, merch, promo — into scope-3 numbers, so procurement teams now ask suppliers for material data as standard.
• The EU’s coming product-passport rules for textiles point the same direction: documented composition, not adjectives.

The greenwash era ended on a specific date. What replaces it isn’t greener products — it’s provable sentences. We’d rather hand you a transaction certificate than an adjective.
