Microplastics
Material-class model assumption
Recycled Polyester is recorded as Recycled Synthetic and tied to Polyethylene terephthalate, which drives the material's microplastics score pressure.

Recycled Polyester clothing: health and sustainability score
Recycled polyester remains polyester; recycled describes its feedstock, not a different non-plastic fiber. Check the actual percentage and the evidence behind the recycled-content claim.
Where it shows up
For activewear or fleece comparisons, compare the recycled share, total blend and construction separately. Recycled content alone does not tell you which item lasts longer.
What the evidence supports
Textile Exchange has standards for recycled-content verification. A recycled label is not a measured shedding rate or a finished-product chemical test.
What remains unknown
Feedstock source, recycling process, dye, finish and product-level life-cycle impacts may remain undisclosed.
Primary sources
- Standards (Textile Exchange)
- Release of synthetic microplastic plastic fibres from domestic washing machines: Effects of fabric type and washing conditions (Marine Pollution Bulletin)

How the model interprets this fiber
Greener Closet scores the disclosed share using the corresponding MaterialsDB record. Its factor defaults are model assumptions, not product testing, a factory life-cycle assessment or independently validated quantitative calibration.
High concern
PFAS uncertainty
Material-class model assumption
Recycled Polyester receives a PFAS uncertainty penalty because performance synthetics and finish-dependent uses can make PFAS claims harder to verify from a label alone.
Half-life and biodegradability
Material-class model assumption
Recycled Polyester is treated as slow to break down, so half-life and biodegradability are major sustainability concerns.
Fiber shedding
Material-class model assumption
Recycled Polyester can shed fibers during wear and washing; the MaterialsDB shedding penalty captures that release risk.
Manufacturing energy
Material-class model assumption
Recycled Polyester carries a manufacturing-energy penalty, so production impacts remain part of the score even when microplastic risk is low.

Best next step
Paste the full fabric label into the homepage checker. A 95% cotton, 5% elastane garment will not score the same as 100% cotton, and the checker handles those percentages.

Common questions
Does Recycled Polyester clothing shed microplastics?
Recycled Polyester is listed in MaterialsDB with Polyethylene terephthalate. That is a default scoring input for microplastic shedding, not a lab result for every finished garment.
Is Recycled Polyester biodegradable?
Recycled Polyester carries a half-life penalty in MaterialsDB, meaning persistence and biodegradability are important concerns.
How should I check a Recycled Polyester blend?
Use the Greener Closet material-label checker with the full percentage label, because blends can change the final score even when Recycled Polyester is only one part of the garment.
