BPI certification confirms that a product meets strict standards for compostability in commercial facilities, ensuring it breaks down safely without leaving harmful residue. It’s one of the most trusted labels for verifying that compostable products perform as claimed.

What Does BPI Certified Mean 

BPI (Biodegradable Products Institute) certification means a product has been independently tested to meet ASTM standards for compostability and will break down in commercial composting conditions. It ensures the product decomposes into non-toxic material within a specific timeframe.

What BPI certification actually verifies

BPI certification verifies that products meet ASTM D6400 or D6868 International standards for defining compostability. These standards ensure materials break down within 90–180 days in industrial composting environments.

Why third-party certification matters

Third-party testing removes guesswork and prevents greenwashing by confirming products meet real composting requirements. This gives businesses and consumers confidence in product claims. The Biodegradable Products Institute (BPI) is the leading North American authority and non-profit organization for certifying compostable products and packaging.

How do products become BPI Certified

Products become BPI certified by undergoing lab testing to prove they meet compostability standards, followed by approval through a formal review process. Manufacturers must demonstrate that materials fully break down without harming the compost ecosystem.

The testing and approval process

Products are tested for biodegradation rate, disintegration, and toxicity. Independent labs verify that the material breaks down into safe compost under controlled conditions.

Ongoing compliance requirements

Certified products must maintain consistent materials and manufacturing processes. Any changes require re-evaluation to keep certification valid.

Why BPI certification is important for compostable products

BPI certification ensures products will actually compost as intended, reducing contamination in composting systems and supporting waste diversion goals. It helps facilities accept materials with confidence and improves overall compost quality.

Preventing contamination in compost streams

Non-certified products can introduce plastics or toxins into compost systems. BPI certification helps facilities avoid contamination that can damage equipment or reduce compost quality.

Supporting composting infrastructure

Composting facilities rely on certified materials to maintain efficient operations. Accepting only verified products helps scale sustainable waste systems.

Can you trust products labeled compostable without BPI Certification

Not all compostable claims are verified, and products without BPI certification may not break down properly in real composting conditions. Certification provides a reliable way to confirm performance and environmental safety.

Risks of uncertified compostable products

Unverified products may fail to break down or leave behind microplastics. This can contaminate compost and lead to rejected waste loads.

How to identify certified products

Look for the BPI logo on packaging or product descriptions. This label confirms the product has passed independent testing and meets recognized standards.

Does BPI certification mean a product is home compostable

A standard BPI certification applies to commercial composting conditions and does not guarantee a product will break down in home compost systems. Home composting environments are less controlled and may not reach the required temperatures. As of late 2025, BPI now offers a specific, separate certification for Home Compostable products.

Differences between commercial and home composting

Commercial facilities maintain high heat and controlled conditions that accelerate decomposition. Home compost systems are slower and less consistent.

What to look for in home compostable products

Products labeled “home compostable” must meet different standards. Look for TÜV OK Compost Home or BPI Home Compostable. Always check labeling before using in backyard compost bins.

How BPI certification supports businesses and sustainability goals

BPI-certified products help businesses meet regulatory requirements, reduce landfill waste, and align with sustainability initiatives. They also improve brand trust with customers who value verified eco-friendly products.

Meeting regulatory requirements

Many regions require organic waste diversion or restrict single-use plastics. Using certified compostable products helps businesses stay compliant.

Building customer trust

Customers are more likely to trust products with recognized certifications. BPI labeling signals transparency and environmental responsibility.
