Compostable vs biodegradable explained

Compostable vs Biodegradable: What's the Real Difference?

If you've been shopping for takeout packaging, you've probably noticed "compostable" and "biodegradable" plastered on everything from coffee cups to clamshell containers. They sound interchangeable. They're not.

Understanding the difference matters — not just for the environment, but for your business. Choosing the wrong packaging can expose you to greenwashing claims, regulatory risk, and customer backlash. Here's what you actually need to know.

What Does "Compostable" Mean?

A compostable product breaks down into natural elements — water, carbon dioxide, and organic matter — within a specific timeframe under specific conditions. In a commercial composting facility, certified compostable packaging fully decomposes within 90 days, leaving no toxic residue behind.

The key word here is certified. Compostable packaging must meet strict third-party standards to earn the label. It's not a vague promise. It's a measurable, verifiable outcome.

Products made from sugarcane bagasse — the fibrous material left over after sugarcane juice is extracted — are a common example of genuinely compostable packaging. If you're not familiar with bagasse, our post on What is Bagasse? covers how it's made and why it works so well for foodservice containers.

What Does "Biodegradable" Mean?

Technically, almost everything is biodegradable. A plastic bottle will biodegrade — it just takes 400 to 1,000 years. A banana peel biodegrades in a few weeks.

"Biodegradable" simply means a material will eventually break down through natural processes. There's no required timeline. There's no required condition. There's no required certification.

That's the problem.

Why "Biodegradable" Is Often Greenwashing

When a packaging company labels their product "biodegradable" without further qualification, they're technically telling the truth while saying almost nothing useful. This is textbook greenwashing — using environmental language to imply a benefit that doesn't meaningfully exist.

Watch out for these red flags:

  • No certification logo on the packaging or product listing
  • Vague claims like "eco-friendly" or "earth-conscious" with no specifics
  • "Biodegradable plastic" — often means conventional plastic with an additive that causes it to fragment into microplastics faster, which is arguably worse
  • No timeline stated for decomposition

If a supplier can't tell you exactly how long their product takes to break down and under what conditions, be skeptical.

The Certification Standards That Actually Matter

Legitimate compostable packaging carries one or more of these certifications:

BPI Certification (Biodegradable Products Institute)

The most widely recognized standard in North America. BPI-certified products have been independently tested and verified to meet ASTM D6400 or ASTM D6868 standards for compostability.

ASTM D6400

The American standard for compostable plastics. Requires the material to disintegrate within 12 weeks and fully biodegrade within 180 days in a commercial composting facility.

CAN/BNQ 0017-088

The Canadian national standard for compostable products. If you're operating in Canada, this is the benchmark your municipality likely references when setting packaging regulations.

Bottom line: If the packaging doesn't carry a recognized certification, the compostable claim is unverified marketing.

What Happens in a Landfill vs a Composting Facility

This is where many people get confused. Even certified compostable packaging won't break down properly in a landfill. Here's why:

In a Landfill

Landfills are designed to prevent decomposition. They're sealed, compacted, and lack the oxygen, moisture, and microbial activity needed for composting. A compostable container buried in a landfill will sit there for decades, just like conventional packaging.

In a Composting Facility

Commercial composting facilities maintain controlled temperatures (55-70 degrees Celsius), consistent moisture levels, and active aeration. Under these conditions, certified compostable products break down completely within 90 days, turning into nutrient-rich soil.

The takeaway: compostable packaging is only as good as the waste infrastructure supporting it. If your municipality has a green bin or commercial composting program, compostable packaging is the right call. Many Canadian cities — including Toronto, Vancouver, and Ottawa — accept certified compostable foodservice packaging in their organics programs.

How to Verify Compostable Claims

Before you commit to a packaging supplier, run through this checklist:

  • Ask for certification numbers. BPI, ASTM D6400, or CAN/BNQ — a legitimate supplier will have these ready.
  • Check the BPI database. You can search for certified products at bpiworld.org.
  • Look at the material. Bagasse, PLA (plant-based plastic), and molded fiber are commonly certified compostable. "Biodegradable plastic" is a red flag.
  • Read the fine print. "Compostable in commercial facilities" is honest. "Biodegradable" with no context is not.
  • Ask your waste hauler. Confirm that your local composting program accepts the specific packaging you're buying.
