Compostability Standards Reference

If you are evaluating compostable packaging on a procurement spec, the three claims worth verifying on every SKU are: (1) a current third-party certificate (BPI or TÜV Austria); (2) the underlying standard reference (ASTM D6400 for North America, EN 13432 for the EU); and (3) a clear end-of-life qualifier in marketing copy that complies with the FTC Green Guides. Generic “eco-friendly” or “biodegradable” without certification is the most common compliance gap for U.S. brands.

Frequently Asked Questions

Is industrial composting accepted in my municipality?

Industrial composter access varies by zip code. Use the U.S. Composting Council facility locator and the EPA composting guidance page; if no industrial facility accepts compostable foodware in the customer’s area, the FTC Green Guides require a “compost where facilities exist” qualifier.

What is the difference between BPI-certified and “made with PLA”?

BPI certification is SKU-specific and requires testing of the finished product — including any inks, coatings, and adhesives. “Made with PLA” only describes a single component and is not a substitute. For procurement contracts, lock the certification number, not the material name.

How long does industrial composting actually take?

ASTM D6400 sets the bar at 90% biodegradation in 180 days under controlled industrial conditions (58 °C, controlled moisture). Real-world municipal facilities typically run 60–90 day cycles, faster than the standard worst case. Items still visible after one cycle are typically removed and re-fed, not landfilled.
