Microplastics
Score impact 45 points
Polyester is recorded as Synthetic and tied to Polyethylene terephthalate, which drives the material's microplastics score pressure.

Polyester clothing: health and sustainability score
Petroleum-based and non-biodegradable, but recycled polyester (rPET) transforms plastic waste into useful textiles. Durable and wrinkle-resistant when properly cared for.
Score drivers
Greener Closet scores materials from several penalty inputs. The same material can be reasonable in one product and weak in another, but these are the default drivers behind the base material record.
Very high concern
PFAS uncertainty
Score impact 12 points
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
Score impact 15 points
Polyester is treated as slow to break down, so half-life and biodegradability are major sustainability concerns.
Fiber shedding
Score impact 4 points
Polyester can shed fibers during wear and washing; the MaterialsDB shedding penalty captures that release risk.
Manufacturing energy
Score impact 8.5 points
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 Polyester clothing shed microplastics?
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 Polyester biodegradable?
Polyester carries a half-life penalty in MaterialsDB, meaning persistence and biodegradability are important concerns.
How should I check a Polyester blend?
Use the Greener Closet material-label checker with the full percentage label, because blends can change the final score even when Polyester is only one part of the garment.
