Recycled Polyester (rPET)
Polyester fiber made from recycled PET, usually post-consumer plastic bottles.
What it is
Recycled polyester is made by mechanically or chemically reprocessing PET — most commonly clear plastic bottles — into chips, then spun into yarn. GRS and RCS are the two main chain-of-custody certifications.
Why it matters
Virgin polyester is petroleum-derived and accounts for over half of global fiber production. rPET cuts fossil-fuel inputs and diverts plastic from landfill, but it doesn't solve the microfiber problem.
Upsides
- Up to 70% less CO2 and 90% less water than virgin polyester
- Diverts plastic bottles from landfill and ocean
- Performs identically to virgin polyester
Trade-offs
- Sheds microplastics during washing — use a Guppyfriend bag
- Mechanical recycling degrades fiber; most rPET is downcycled after one loop
- Bottle-to-textile recycling can compete with bottle-to-bottle, which is more circular
What to look for on the label
GRS (Global Recycled Standard) or RCS certification with stated recycled content percentage and a transaction certificate.

Frequently asked
Does recycled polyester shed microplastics?+
Yes, the same as virgin polyester. Wash in a microfiber-trapping bag, use cold cycles, and air-dry to reduce shedding.
Is rPET safe to wear next to skin?+
Reputable GRS-certified fiber is tested for restricted substances. Avoid bargain rPET without a chain-of-custody certificate, which can contain antimony or dye residues.

Choosing a product made with recycled polyester (rpet)
GRS (Global Recycled Standard) or RCS certification with stated recycled content percentage and a transaction certificate.
Compare products intended for the same job. A broad category can include different sizes, formats and specifications, so treat the ranking as a starting shortlist rather than a universal winner.
What to check before choosing
| Factor | Check before buying | Why it matters |
|---|---|---|
| Fit for the task | Match size, capacity and compatibility to the job you need done. | A higher overall score cannot compensate for a missing essential requirement. |
| Total ownership cost | Include refills, accessories, shipping and maintenance in your budget. | The lowest upfront price is not always the lowest cost over regular use. |
| Evidence and aftercare | Read product-specific sources, warranty exclusions and return conditions. | Brand claims and broad rankings are starting points, not guarantees for an individual purchase. |
Read the evidence, not just the score
Quality, Value, User Experience and Brand & Trust measure different trade-offs. The default weights are 30%, 25%, 25% and 20%; category overrides can differ. A close score gap is less useful than a clear advantage on the factor you care about. Look at the product's recorded specifications, drawbacks and source links, and distinguish a manufacturer's claim from independent testing.
Build a realistic shortlist
- Remove options that miss an essential size, compatibility or safety requirement.
- Compare two or three remaining options on total cost and the drawbacks you can accept.
- Confirm the exact variant, warranty and return terms with the seller.
