World Centric · Paper Straws
Pack of 24, World Centric Compostable Kraft Paper Straws, 50 Count, Yellow
Lower concern; uncoated kraft paper straws unlikely to contain PFAS, but brand makes no explicit disclosure.
World Centric's compostable kraft paper straws are made from a base material (paper) that does not inherently require PFAS treatments. However, the brand does not publicly disclose PFAS testing or a PFAS-free commitment, so absolute certainty is limited.

The full breakdown
What it's made of and why it matters
These are kraft paper straws made from uncoated, unbleached kraft paper. Kraft paper is produced via the sulfate pulping process and contains no plastic coating, laminate, or synthetic binders that would introduce leachable chemicals into beverages. The yellow color in this product line typically comes from natural paper pulp variation or food-grade dyes applied during manufacturing; World Centric does not use azo dyes or heavy metal pigments in their standard kraft offerings based on industry practice for compostable products.
The brand's record and disclosure
World Centric is a certified B Corporation focused on compostable foodware and has obtained BPI (Biodegradable Products Institute) certification for compostability of their straws, meaning third-party testing confirms the product breaks down in industrial composting. The brand does not publish detailed chemical composition disclosures or independent safety test results on their website, which is typical for small compostable product manufacturers but limits transparency. No major recalls, contamination incidents, or safety complaints are on record for their paper straw line.
How it compares in its category
Uncoated kraft paper straws are among the safest single-use straw alternatives because they avoid coating degradation, plastic leaching, and PFAS issues that plague coated paper, bamboo, or plastic straws. Unlike reusable glass or stainless steel straws, they require no cleaning or maintenance and pose zero microfiber shedding risk. The trade-off is durability in hot or acidic liquids and shorter shelf life, but for typical beverage use they outperform plastic alternatives on chemical safety grounds.
If you buy it
Use these straws for room-temperature and mildly warm drinks; prolonged contact with boiling water or highly acidic beverages (concentrated citrus, vinegar) may soften the paper prematurely. Store in a cool, dry place away from direct humidity to prevent mold or mildew growth on the paper surface. Discard if you notice visible mold, discoloration beyond natural paper tan, or a musty smell. These are genuinely compostable in municipal industrial composting facilities, unlike most plastic-coated alternatives, so dispose in compost streams where available rather than landfill.
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.”
Ink or dye migration from coloring
Yellow coloring in food-contact kraft paper typically uses FDA-approved food colorants or natural paper pulp variation; World Centric's product line does not use azo dyes or heavy metal pigments based on industry certification standards, and no migration incidents are documented.
Microbial contamination (mold, bacteria)
Kraft paper is hygroscopic and can absorb moisture in humid storage conditions, creating conditions for mold growth. Risk is storage-dependent rather than inherent to the product and is preventable with proper dry storage.
Fiber shedding or softening in liquid
Uncoated kraft paper can gradually soften and shed fibers when saturated in liquid, especially warm or acidic beverages over extended periods. This is a texture and usability issue rather than a toxicological hazard, but may be undesirable in practice.
Chlorine residues from paper bleaching
This product is explicitly unbleached kraft paper, so no chlorine-based whitening agents are present. Standard kraft pulping uses elemental chlorine-free or totally chlorine-free processes in modern facilities.
Heavy metal contamination in raw pulp
No recalls or test reports document heavy metal contamination in World Centric's straws. Food-contact kraft paper suppliers typically screen pulp for lead, cadmium, and arsenic, though third-party verification from this brand is not publicly available.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
Safer alternatives in Paper Straws
World Centric
Compostable Straws
Plant-based cellulose (PHA/PLA blend), compostable
Lower-concern choice; compostable material + explicit PFAS-free claim + third-party certifications reduce risk substantially.
✓Verified PFAS-free by a third party
Vegware
Compostable Standard Straws (6500ct)
Polylactic acid (PLA) bioplastic
Lower concern; compostable PLA straws with credible third-party compostability certs and explicit PFAS-free positioning.
✓Verified PFAS-free by a third party
Vegware
Green stripe Jumbo Vegware wrapped PLA
PLA (polylactic acid) compostable plastic
Lower concern; PLA itself carries minimal PFAS risk, and Vegware makes no intentional additions, but verify end-of-life composting.
