Yes, many paper straws contain PFAS—persistent chemicals that earn the nickname “forever chemicals.” Studies from 2023 and 2024 detected PFAS in paper straws from several major brands, raising serious questions about their safety. This finding challenges the assumption that paper straws are inherently eco-friendly and highlights hidden health concerns.
What Are PFAS and Why Do They Matter?
PFAS, or per- and polyfluoroalkyl substances, are synthetic chemicals used to repel grease and water. They are called “forever chemicals” because they do not break down in the environment or the human body. Exposure to even low levels of PFAS has been linked to liver damage, immune system issues, and certain cancers. Consequently, their presence in everyday items like straws demands scrutiny.

The Surprising Truth: PFAS in Paper Straws
A 2023 Belgian study tested 39 brands of paper straws and found PFAS in 69% of them. Similarly, a 2024 U.S. investigation detected PFAS in paper straws from major restaurant chains. These findings indicate that PFAS contamination is widespread, contradicting the marketing of paper straws as a pure, green alternative.
Key findings on PFAS in paper straws include:
- Nearly 70% of tested paper straws contained at least one type of PFAS.
- The most common PFAS detected were PFOA and PFOS, which are being phased out globally.
- Even straws labeled “eco-friendly” or “compostable” often tested positive for these chemicals.
However, PFAS is not limited to paper straws. Reusable straws made from bamboo or other plant materials also show traces. This challenges the entire biodegradable straw safety narrative.
Beyond Paper: Other Non-Plastic Straws at Risk
While the spotlight is on PFAS in paper straws, bamboo and other plant-based straws can also harbor these chemicals. Manufacturers often add coatings to improve durability, and those coatings may contain PFAS. For instance, a 2023 study found PFAS in bamboo straws at rates similar to paper.
This revelation underscores the eco-friendly straw risks that consumers rarely consider. Even compostable straws can introduce toxic chemicals into landfills or oceans.

How to Choose Safe Straws Without PFAS
Avoiding PFAS requires careful selection. Look for straws explicitly labeled “PFAS-free” or made from materials that don’t need chemical coatings. Safe sustainable straw alternatives include:
- Stainless steel or glass straws (reusable, no coatings)
- Silicone straws (soft, PFAS-free when clearly stated)
- PLA (polylactic acid) straws from plant starch (many are PFAS-free)
- Paper straws verified by third-party testing for PFAS

By choosing verified PFAS-free products, you can enjoy the convenience of disposable or reusable straws without the hidden chemical burden.
FAQ
Q: Do paper straws contain PFAS?
A: Yes, studies from 2023 and 2024 have found PFAS in a majority of paper straws tested from various brands. The prevalence of PFAS in paper straws is around 69%, meaning many popular brands may expose users to these forever chemicals.
Q: Are paper straws safe to use?
A: Not necessarily. Even short-term exposure to PFAS from paper straws can contribute to cumulative chemical buildup in the body. While occasional use may pose low risk, regular use of contaminated paper straws raises concerns about long-term health effects.
Q: What are the best sustainable straw alternatives without PFAS?
A: The safest options include stainless steel, glass, and silicone straws that are explicitly PFAS-free. Among disposable choices, look for paper straws with third-party PFAS testing or PLA straws made from non-coated plant starches. Always check manufacturer claims for verified PFAS-free status.
Conclusion
The discovery of PFAS in paper straws shatters the illusion of a perfectly green swap. However, this doesn’t mean we must return to plastic. By staying informed and choosing verified sustainable alternatives, you can reduce both environmental and health risks. At ZTstraw, we are committed to providing PFAS-free, eco-friendly straws.
