With BPI certification, can my product be composted in a backyard?

Not necessarily. Standard BPI certification is for industrial composting facilities. If the packaging clearly states "BPI Certified Home Compostable," it has passed testing under milder, longer-term home composting conditions. Always judge and dispose of the product based on the specific label.

Is a BPI certificate valid forever?

No. A BPI certification certificate is valid for 3 years. Upon expiry, the manufacturer must submit a renewal application (which may involve partial re-testing or documentation updates). During this period, BPI conducts continuous market surveillance and random checks to maintain the integrity of the certification system.

With BPI certification, is my product automatically compliant in Canada?

It is widely recognized. BPI certification is one of the most effective ways to meet similar regulatory requirements in Canada. However, it's important to note that Canada and other jurisdictions may have their own evolving local regulations for specific chemicals (like PFAS). Therefore, choosing a manufacturer that proactively monitors and ensures compliance with the latest standards in all target markets is crucial.

Does certification apply to a product series or a single SKU?

Certification applies to a specific formulation. Once a formulation is certified, products of different shapes and sizes based on that formulation (e.g., takeout containers of different capacities) can be covered.

BPI Certification for Compostable Packaging in North America

Market Access in North America: Why “Compostable” Claims Need Third-Party Backing

In North America, particularly the United States, the Federal Trade Commission’s (FTC) Green Guides and various state “green procurement” laws impose strict regulations on environmental claims. Self-declared “compostable” claims without authoritative third-party verification can easily constitute “greenwashing,” risking both legal and reputational damage. Municipal composting facilities, major retailers, and eco-conscious consumers all demand clear, trustworthy labels on packaging. BPI Certification emerged as the market consensus in this environment. Endorsed by a leading North American authority, it serves as a standardized bridge of trust connecting credible manufacturers with end-of-life processing infrastructure.

The Scientific Foundation: A Detailed Look at the ASTM D6400 Standard

The authority of BPI certification is rooted in its strict adherence to the American Society for Testing and Materials standard ASTM D6400. Similar to Europe’s EN 13432, this is a complete scientific evaluation system. Products must pass the following three rigorous tests:

Biodegradability Test: In a simulated industrial composting environment (58°C, oxygen-rich), materials must achieve over 90% conversion of organic carbon to carbon dioxide within 180 days. This is the core proof that the material can be completely “digested” by microorganisms.
Disintegration Test: After 12 weeks in an actual composting test, materials must pass through a 2-mm sieve, ensuring they won’t contaminate the final compost with visible fragments.
Ecotoxicity Test: The resulting compost must be non-toxic to plant growth, guaranteeing its safety and value as a soil amendment.

Beyond these core biological tests, the standard sets extremely strict limits on chemical composition, particularly for heavy metals (like cadmium, lead, mercury) and fluorine compounds (PFAS). These limits are not static; they evolve with the latest scientific understanding and local regulations (such as PFAS bans in several U.S. states), ensuring the absolute safety of the compost. This places ongoing demands on a manufacturer’s ability to control raw materials and keep pace with regulatory changes.

Only after passing all these tests is a product authorized to carry the BPI “seedling” logo.

Key Differentiation: BPI vs. OK Compost – How to Choose?

Global comparison of BPI ASTM D6400 and OK Compost EN 13432 compostable standards

BPI and OK Compost are the two pillars of global industrial composting certification, with highly aligned technical cores. Their main differences are:

Regulatory Geography: BPI is based on the U.S. ASTM D6400 standard and is the de facto market access standard in North America (U.S./Canada). OK Compost is based on the European EN 13432 standard and prevails in the EU and globally influenced markets.
Market Recognition: North American retailers, composters, and consumers are more familiar with and trust the BPI logo. Choosing BPI means communicating in the market’s “local language.”
Certification Specifics: Notably, the BPI system itself caters to diverse needs. Alongside the mainstream Industrial Composting certification, BPI also offers a “Home Composting” certification for products targeting backyard composting scenarios, reflecting further market refinement.
