Biodegradable

Biodegradable refers to materials that can be broken down by microorganisms—such as bacteria, fungi, or algae—into natural elements like water, carbon dioxide, and biomass, typically within a defined timeframe under specific environmental conditions. Unlike non-biodegradable plastics that persist for centuries, biodegradable products are designed to return to nature safely. This process requires the right balance of oxygen, moisture, and microbial activity, meaning not all biodegradable items decompose effectively in a standard landfill. For North American consumers exploring sustainable lifestyle choices—from pet waste bags to craft supplies—understanding the standards and real-world performance of biodegradable claims is essential for making genuinely eco-friendly purchases.

What Is Biodegradable? — 2026 Definition

In 2026, a material is considered biodegradable if it meets a recognized standard, such as ASTM D6400 (for compostable plastics) or EN 13432 (European standard for packaging). These standards require that at least 90% of the material’s carbon is converted to CO2 within 180 days in an industrial composting facility. The term “biodegradable” is often confused with “compostable,” but the key difference lies in the timeframe and conditions required. The Federal Trade Commission (FTC) Green Guides and the Biodegradable Products Institute (BPI) certification help consumers identify genuine products. In the U.S., California’s SB 54 (2022) and similar state laws are tightening definitions to combat greenwashing, and as of 2025, the FTC is updating its Green Guides to further restrict unqualified “biodegradable” claims.

Feature	Biodegradable	Compostable	Oxo-Degradable	Recyclable

End Product	CO2, water, biomass	CO2, water, nutrient-rich compost	Microplastics + fragments	Raw material for new products
Certification Example	BPI, OK Compost HOME	BPI, TÜV Austria	None (often banned)	How2Recycle
Best For	Single-use items in controlled waste streams	Food packaging, yard waste bags	Not recommended	Aluminum, glass, paper, rigid plastics

How Biodegradable Products Work in 2026

The mechanism behind biodegradation relies on microorganisms secreting enzymes that cleave polymer chains into smaller molecules, which are then metabolized into energy, CO2, and water. According to the Biodegradable Products Institute (BPI, 2025), over 70% of products labeled “biodegradable” in the U.S. do not meet the ASTM D6400 standard for compostability. This gap has driven regulatory action: as of January 2026, Washington State’s “Truth in Labeling” law requires all plastic products labeled as “biodegradable” to carry a BPI or TÜV Austria certification. Major retailers like Amazon and Walmart have also updated their private-label packaging policies to require third-party biodegradability certification by 2026. In the pet wellness space, brands like Earth Rated and Pogi’s now offer certified compostable dog waste bags that meet ASTM D6400, while craft subscription services like Green Kid Crafts use biodegradable packing peanuts made from wheat starch. The key takeaway for 2026: consumer trust increasingly hinges on third-party certification, not just marketing language.

Biodegradable vs. Compostable, Recyclable, and Oxo-Degradable: Comparison Table

Name	Key Differentiator	Typical Cost	Best For	Verto Recommendation
Biodegradable	Breaks down in nature, but timeframe varies	$0.10–$0.30 per unit (bags)	General-purpose single-use items where composting isn’t available	Use with caution; look for BPI certification
Compostable	Breaks down in 90–180 days in industrial facility	$0.15–$0.40 per unit (bags)	Food scraps, yard waste, packaging for organic waste streams	Best choice when industrial composting is accessible
Recyclable	Reprocessed into new materials; no decomposition	$0.05–$0.20 per unit (plastic)	Rigid plastics (#1, #2, #5), glass, metal, paper	Preferred for durable goods; check local facilities
Oxo-Degradable	Fragments into microplastics via chemical additives	$0.08–$0.15 per unit (bags)	Not recommended; banned in EU and several U.S. states	Avoid entirely; does not provide environmental benefit

Our Recommendation: For most North American consumers, compostable products certified by BPI or TÜV Austria are the most reliable choice for single-use items like dog waste bags or food packaging. Recyclable materials are better for durable goods like beverage containers. Biodegradable without certification carries too much uncertainty. Oxo-degradable products should be avoided entirely.

Who Should Use Biodegradable Products? (and Who Shouldn’t)

Use biodegradable products if: You live in a community with access to industrial composting facilities (check with your local waste management provider) and you are purchasing items like certified compostable pet waste bags (e.g., Earth Rated, 2026 line) or compostable packing materials from craft subscription services. These products work best when you can ensure they enter a controlled composting stream.

Avoid biodegradable products if: Your local waste system sends all trash to a landfill without sorting for composting. In a typical landfill, even certified compostable items may not break down due to lack of oxygen and moisture. If you cannot compost at home or access municipal composting, choose recyclable alternatives instead. For pet waste specifically, flushing (where local regulations permit) or using a dedicated pet waste composting system may be more effective than relying on “biodegradable” bags in a landfill.

Key Factors to Consider When Evaluating Biodegradable Products

When shopping for biodegradable products in 2026, use this checklist to avoid greenwashing and make genuinely sustainable choices:

Factor	What to Look For	Why It Matters
Third-Party Certification	BPI, TÜV Austria, OK Compost HOME	Independent verification of claims; required by new state laws
End-of-Life Pathway	Industrial vs. home composting vs. landfill	Determines whether the product actually breaks down
Material Type	PLA (polylactic acid), PBAT, starch blends	Some bioplastics require specific conditions; avoid PLA for home compost
Local Infrastructure	Check your municipality’s composting acceptance	Many facilities reject compostable plastics
Cost Premium	Typically 20–50% more than conventional plastic	Evaluate whether the environmental benefit justifies the cost for your use case
Brand Reputation	Earth Rated, Pogi’s, Green Kid Crafts, Eco-Products	Established brands invest in certification and transparency
