BPI Certification (Industrial Compostable Standard for North America)

Table of Contents

询盘表单

When you see a product marked with BPI Certified Compostable, it means something very specific. It means the product was tested under strict rules to confirm it can break down in an industrial composting facility. As someone who works with compostable materials every day, I want to explain what this certification means and how you can use it with confidence.

This page is not about composting theory or marketing claims. It is about real certification, backed by testing standards like ASTM D6400 and ASTM D6868, which the Biodegradable Products Institute (BPI) uses to approve compostable products in the United States and Canada.

BPI certification

What Is BPI Certification?

BPI Certification is a third-party program run by the Biodegradable Products Institute. BPI checks whether a product can safely break down in commercial compost systems. These systems operate at high temperatures and have controlled airflow and moisture. They are very different from a backyard compost bin.

To become BPI certified, a product must meet the rules of:

  • ASTM D6400 – compostable plastics

  • ASTM D6868 – compostable coatings, paper liners, and packaging

BPI also checks the product’s ingredients and reviews its labeling. When a product passes all steps, it earns the BPI Certified Compostable Mark. Composting facilities in the U.S. use this mark as a trusted signal. https://bpiworld.org/Certification

Standards Behind BPI Certification (ASTM D6400 & ASTM D6868)

These two standards are the backbone of the BPI program. They are technical documents, but I can summarize them simply.

ASTM D6400

This standard applies to compostable plastics. It measures how fast the plastic biodegrades, how well it breaks apart, and whether it harms the finished compost.

ASTM D6868

This standard applies to items made of paper or fiber that include a compostable coating or film. It makes sure the coating also meets composting rules.

Together, they provide clear criteria for industrial compostable certification in North America.

Key Requirements for BPI Certification

For a product to earn the BPI certified compostable label, it must pass several scientific tests. These tests are done by independent labs.

1. Biodegradation

The material must convert into carbon dioxide, water, and biomass. It cannot remain as microplastic. This process must follow the curve defined in ASTM D6400.

2. Disintegration (84 Days / 12 Weeks)

In a commercial composting system, the item must break into small fragments. After 12 weeks, no large pieces should remain. This is important for compost quality.

3. Ecotoxicity and Plant Safety

The finished compost must support healthy plant growth. It must not introduce harmful chemicals or toxic byproducts into the soil.

4. Heavy Metals and Hazardous Substances

BPI enforces limits on metals like lead, cadmium, and mercury.
In recent years, BPI also added rules that restrict PFAS and other chemicals found to be harmful in composting systems (source: BPI policy update, 2023–2024).

5. Ingredient Review and Labeling

BPI reviews every additive, coating, and ink used in the product. The label must follow BPI’s style guide so composters can quickly identify certified items.

These requirements make BPI one of the most reliable industrial compostability certifications in North America.

Why BPI Certification Matters for Businesses

Your customers, waste haulers, and composting facilities need clear and honest labeling. BPI certification helps solve several real-world problems:

  • Avoiding greenwashing
    Many products claim to be “biodegradable.” Without testing, this claim is unreliable.

  • Accepted by composting facilities
    Many U.S. municipal programs only accept BPI certified compostable bags and packaging.

  • Meeting retailer and food service requirements
    Large food chains and supermarkets often require suppliers to use certified compostable packaging in their organics programs.

  • Supporting sustainability goals
    Certified products help move food scraps and compostable packaging away from landfills and into industrial compost systems.

For companies selling compostable bags, liners, and packaging, BPI certification is not a bonus. It is essential.

Composting facilities rely on BPI certification because it helps them keep contamination low and maintain high-quality compost. Clear labeling reduces sorting problems and prevents non-compostable plastics from entering the system.

How to Apply for BPI Certification (Step-by-Step Guide)

Getting a product certified by BPI involves several scientific evaluations and documentation checks.
Here is the complete application process:

Step 1 — Prepare Product Documentation

You must provide:

  • Full material composition (PLA/PBAT/Starch ratios)

  • Additive, colorant, and ink disclosures

  • Safety Data Sheets (SDS)

  • Product drawings / film structure

  • Intended end-use (bags, liners, packaging, mailers, etc.)

BPI requires 100% ingredient transparency before testing begins.

Step 2 — Pre-Screening Review by BPI

BPI reviews material safety and ingredient compliance.

If any chemical exceeds limits (such as PFAS, heavy metals), the product cannot enter certification testing.

Step 3 — Laboratory Testing (ASTM D6400 or D6868)

Testing must be conducted by a BPI-approved independent laboratory, which evaluates:

  • Biodegradation curve

  • Disintegration (84-day breakdown test)

  • Ecotoxicity (plant growth test)

  • Heavy metal limits

  • Chemical safety

Testing typically takes 90–180 days depending on the product.

Step 4 — BPI Technical Review

After the lab submits test data, BPI performs:

  • A technical audit

  • Ingredient review

  • Labeling review

  • Packaging inspection

Step 5 — Approval & Certificate Issuance

When all requirements are met, BPI issues:

  • Certificate Number

  • Approved Products List

  • Logo Usage Authorization

  • Validity Period Information

Products must be renewed every 3 years, or earlier if the formula changes.

Step 6 — Listing on the BPI Public Database

Once approved, the product becomes publicly searchable on the BPI official website — a key requirement for waste facilities and retailers.

How to Verify a BPI Certified Product

Online and on Reddit, I notice many people confused by labels. Some products look “green,” but they are not certified. Here is a clear way to check:

1. Search the BPI Official Database

Go to BPI’s website and type the product name or company name.
If it is not listed, it is not certified.

2. Check the Certificate Number

A real BPI certified compostable product will include a valid certificate number. This number should match the database entry.

The BPI logo must follow the approved shape and text.
If the logo looks stretched, incomplete, or missing the word “Certified,” it may not be legitimate.

4. Know the Difference: Resin Certification vs Product Certification

Sometimes a raw material resin is certified, but the finished product is not.
A bag, cup, or film must be certified as a final item, not only by material.

5. Watch for Greenwashing

Claims like “earth-friendly,” “oxo-biodegradable,” or “biodegradable plastic” do not guarantee compostability.

By following these steps, you can avoid false claims and choose trustworthy compostable packaging.

You can verify any certified item through the official BPI Product Database:

Composting Facilities & Waste Management Companies

Correct Disposal of BPI Certified Products

A BPI certified product is meant for industrial composting, not a backyard compost pile. The temperatures in home compost are usually too low to meet ASTM conditions.

To dispose of certified items correctly:

  • Place them in your local organics or food waste bin

  • Check whether your city accepts compostable packaging

  • Do not put them in recycling bins

  • Do not send them to landfill unless you have no composting option

Using the right bin keeps compost free from contamination and protects the composting system.

Where Is BPI Certification Required or Recommended?

Why Products Fail BPI Certification

Even well-designed compostable products may fail testing due to:

1. Materials that do not biodegrade fast enough

Example:

  • PBAT ratio too high

  • PLA crystallinity causing slow biodegradation

2. Excessive thickness

If the bag is too thick, it may not disintegrate within 84 days.

3. Toxicity or chemical safety issues

Including:

  • Heavy metals above limits

  • Non-compliant inks or pigment

  • Additives failing plant growth tests

4. Incorrect or incomplete documentation

This is one of the most common reasons manufacturers fail.

If labeling violates guidelines, certification can be suspended.

6. Resin certified ≠ finished product certified

Many companies misunderstand this rule.
