In 2026, "compostable" and "PFAS-free" stopped being marketing adjectives and became procurement requirements. Eleven US states plus 250+ municipalities restrict polystyrene foam, and a growing patchwork of state laws bans intentionally added PFAS in food packaging. Buyers who cannot document compliance are increasingly locked out of bids.
What "Compostable" Requires
A napkin is compostable only with the right certification backing the claim. The two recognised marks are:
- BPI (Biodegradable Products Institute): certifies conformity to ASTM D6400 (US industrial composting).
- OK Compost INDUSTRIAL (TÜV AUSTRIA): certifies disintegration and biodegradation in a commercial composting facility, typically within 12 weeks.
- Seedling / OK Compost HOME: for the narrower home-compost route.
Industrial vs Home Composting
Most certified compostable napkins are industrial only — they need the heat and microbial activity of a commercial facility. If your venue lacks commercial composting, the claim still satisfies procurement rules, but the napkin will behave like paper in a landfill. Match the certification to the disposal route you actually have.
PFAS-Free: The Non-Negotiable
PFAS ("forever chemicals") were used for grease resistance. State laws in California (AB 1200), New York, Washington, Colorado, Maryland, Minnesota and others now ban intentionally added PFAS in food packaging. A compliant napkin must carry no added PFAS at any stage — and the supplier should provide lab documentation, not just a badge.
How to Verify a Supplier’s Claim
| Ask for | Why |
|---|---|
| Valid certificate number | Not just a logo image |
| PFAS lab report | Proves no intentionally added PFAS |

Key Takeaways
- "Compostable" needs BPI or OK Compost certification — a self-declaration is not enough.
- Most certified napkins are industrial-compost only; match the cert to your disposal route.
- PFAS-free is now a legal requirement in many US states, not a nice-to-have.
- Always request valid certificate numbers and a PFAS lab report, not just badge images.
