Repurpose 100% Compostable Plant Based Clear Cold Cup
Lower-concern choice; compostable plant-based cups avoid typical PFAS coatings, but no explicit testing disclosed.
Repurpose's 100% compostable plant-based clear cold cups are made from biopolymers rather than conventional plastics or Teflon-family coating coatings, which reduces typical PFAS risk pathways. However, the brand makes no public statement about PFAS testing or claims.

Why this grade
Category baseline

No PFAS disclosure
No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
This cup is made from polylactic acid (PLA) or similar plant-derived biopolymer, typically sourced from corn starch or sugarcane. Unlike conventional plastic cups, PLA does not require synthetic petroleum feedstock and degrades in industrial composting environments. The clear plastic formulation avoids colorant pigments and dyes, which reduces risk of heavy metal leaching (a hazard in dyed or opaque versions). The material itself is chemically stable at room temperature and performs well for cold liquids.
The brand's record and disclosure
Repurpose operates under a compostability-focused brand positioning but public disclosure of third-party chemical testing (beyond compostability certification) is limited. The company does not appear to have published detailed non-PFAS chemical safety reports or full ingredient/additive transparency. No major recalls or safety controversies are documented in public records for this product line. Certifications such as BPI (Biodegradable Products Institute) or equivalent validate compostability but do not guarantee disclosure of all processing aids or mold-release agents.
How it compares in its category
Compostable plant-based cups are a lower-hazard alternative to polystyrene foam cups (which may leach styrene) and multi-layer paper cups lined with fluorinated polymers (PFAS-containing). Traditional plastic (PET or polypropylene) cups are more widely recycled but do not biodegrade. This product avoids both PFAS and persistent synthetic polymers, placing it in the safer half of the cold-cup spectrum; trade-off is that composting infrastructure must be available.
If you buy it
Use for cold beverages only; PLA softens significantly above 50-60°C and is not intended for hot drinks or reheating. Do not leave filled cups in direct sunlight for extended periods, as UV exposure and thermal stress can degrade the material over time. Rinse and allow to dry after use to prevent mold growth in moisture pockets. Dispose in industrial composting facilities if available; standard recycling or landfill does not achieve degradation.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Plasticizer or monomer leaching (residual)
PLA production and processing may leave trace monomers or catalytic residues; risk is minimal for cold drinks but not explicitly tested by brand.
Mold or bacterial growth if stored wet
Porous or slightly textured inner surfaces on compostable cups can harbor microorganisms if not dried promptly; standard hygiene practice mitigates this.
Degradation byproducts from UV or thermal stress
Outdoor storage or exposure to high heat may cause PLA to degrade into oligomers; risk is low for intended cold-drink use and proper storage.
Heavy metal pigments in dye or colorant
Clear formulation avoids opaque or colored inks; no reports of cadmium or lead in transparent PLA cups from this brand.
Formaldehyde or volatile organic compound off-gassing
PLA does not require formaldehyde-based resins or high-temperature curing processes typical of thermoset plastics; off-gassing risk is not documented.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
