World Centric St-pa 10-k 10" Paper Straw
Lower-concern product, but World Centric provides no public PFAS disclosure.
Paper straws are inherently lower-PFAS-risk compared to coated or treated food packaging. World Centric does not publicly disclose whether any coatings, sealants, or treatments applied to this product contain PFAS, a common omission in the category. No third-party PFAS testing data is available for this specific SKU.

The full breakdown
What it's made of and why it matters
World Centric's St-Pa 10-K straws are paper-based, typically kraft paper or similar food-grade stock. The brand does not publicly disclose whether the paper has a coating, sealant, or waterproofing treatment, which is the critical detail: uncoated paper will absorb liquids quickly, while food-contact coatings (often wax, starch, or oil-based) prevent degradation but introduce potential leaching vectors. Paper itself carries negligible chemical hazard compared to plastics or coated metals, but the hidden coating, if present and undisclosed, is a transparency problem.
The brand's record and disclosure
World Centric markets itself as an eco-conscious, compostable-focused brand and holds certifications including BPI (Biodegradable Products Institute) compostability. However, the company provides no public statement on PFAS testing, avoidance, or disclosure practices for its straws or other products. This silence is notable because paper products sometimes receive water-repellent coatings (historically including PFAS-based chemistries like AFFF), and competitors in the paper-straw space have begun voluntarily disclosing PFAS status. No recalls or safety incidents specific to this product are on record.
How it compares in its category
Paper straws are among the safest single-use straw options from a leaching perspective, ahead of plastic and comparable to glass. Many competitors (e.g., Aardvark, Footprint) have published PFAS commitments or third-party test results; World Centric's lack of disclosure puts it in a weaker position on transparency, though not necessarily product safety. The 10-K's specific coating or treatment status is unknown, limiting ability to benchmark precisely.
If you buy it
Use straws with room-temperature or warm liquids (not boiling or prolonged heat exposure, which could degrade any coating and increase leaching risk). Replace immediately if the straw shows visible softening, disintegration, or color bleeding. Composting works well if your facility accepts them; standard landfill or recycling is less ideal. Contact World Centric directly if PFAS assurance matters to you, their silence suggests they have not tested or prioritized this communication.
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.”
Coating leachates (identity unknown)
World Centric does not disclose the waterproofing or sealant used on these straws. If a wax or oil-based coating is present, minimal leaching is expected under normal use; if a legacy PFAS-based water-repellent treatment was used, risk exists but is unconfirmed and undocumented.
Paper degradation and microparticles
Paper straws shed fibers and small fragments, especially in warm or acidic liquids. This is normal and not classified as a health hazard, but consumers with extreme sensitivity to paper ingestion may prefer alternatives.
Formaldehyde in paper processing resins
Food-contact paper products can contain trace formaldehyde from wet-strength or sizing resins. No evidence of formaldehyde issues in World Centric straws; standard kraft paper uses minimal formaldehyde additives and is regulated by FDA limits.
Ink or printing contaminants
If straws are printed (not specified for this model), food-contact inks must meet FDA standards. World Centric's marketing materials do not indicate heavy branding on the 10-K straw itself, minimizing this risk.
Chlorine bleaching residues
Some paper products are chlorine-bleached, which can leave trace dioxins or other residues. World Centric does not specify the pulping method; industry standard is elemental-chlorine-free (ECF) or totally-chlorine-free (TCF), with minimal food-contact risk from either.
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.
