Certifications

Proven.
Not promised.

Compostable is a word that’s been over-used into meaninglessness. These are the four certifications we hold, the labs that issue them, and exactly what they require us to prove.

  • Biodegradable Products Institute · United States & Canada

    BPI Certified

    Verified by BPI

    Read the standard

    Independent, third-party verification that a product meets ASTM D6400 and is suitable for industrial composting facilities across North America. The BPI logo is what US composting facility operators look for when deciding whether a bag is genuinely compostable, and it's required by many municipal organics programs that accept compostable packaging.

    What it requires

    • Compliance with ASTM D6400 verified
    • Annual recertification and audit
    • Listed in BPI's public certified-products database
    • Accepted in major US and Canadian municipal composting streams

  • ASTM International · United States & Canada

    ASTM D6400

    Industrial compostability

    Read the standard

    The American specification for plastics designed to compost in municipal and industrial composting facilities. ASTM D6400 is the prerequisite for BPI certification and for the term "compostable" being used legally on packaging across most of the United States and Canada.

    What it requires

    • Biodegradation: ≥ 90% within 180 days
    • Disintegration: no more than 10% > 2 mm at the end of the test
    • Tested at 58 °C ± 2 °C
    • Plant-growth and heavy-metal toxicity bounded

  • TÜV Austria · International

    OK Compost HOME

    Home composting

    Read the standard

    TÜV Austria's most demanding compostability mark. Verifies that the bag will fully disintegrate and biodegrade in the cooler, less controlled conditions of a backyard compost heap — typically 68–86 °F, not the 130–140 °F of industrial facilities. It means a customer can dispose of our bag without depending on municipal infrastructure.

    What it requires

    • Disintegration: ≥ 90% within 6 months
    • Biodegradation: ≥ 90% within 12 months
    • No heavy metals, no eco-toxicity
    • Test temperature: 68–86 °F (ambient)

  • European Standard (CEN) · European Union

    EN 13432

    European compostability

    Read the standard

    The harmonized European Standard for packaging recoverable through composting and biodegradation. EN 13432 is the legal benchmark that defines what "compostable" means in the EU — and is the basis for the seedling logo you see on certified compostable products. Tested against industrial composting conditions (around 136 °F).

    What it requires

    • Disintegration: ≥ 90% within 12 weeks
    • Biodegradation: ≥ 90% within 6 months
    • No negative effect on compost quality
    • Heavy metals tested below threshold

How we hold ourselves to it

A logo on a bag isn’t enough.

Certifications are easy to claim and difficult to maintain. These are the three practices we use to make sure ours stay real.

  • 01

    Third-party verified

    Every certification on our bags is issued by an independent body — not self-claimed. The certifying lab tests our actual material, not a sample we hand-pick.

  • 02

    Annual recertification

    Standards drift. Suppliers drift. We re-test our compound every twelve months to make sure what we ship today still meets the mark we sold you yesterday.

  • 03

    Full chain of custody

    We can trace every roll of film back to the resin batch, the certifying lot, and the test report. Available on request to wholesale buyers.
