What does biodegradable mean on labels?

What the Green Guides say

The FTC Green Guides (16 CFR Part 260) are federal guidance on environmental marketing claims. For degradable and biodegradable claims, they generally expect that an unqualified claim is backed by evidence that the entire item will fully break down and return to nature within a reasonably short period after customary disposal.

That standard matters because most household trash goes to landfills, incinerators or recycling. The Guides note that items sent to those places may not break down in the way the claim implies, so a marketer needs to be careful about what it promises and may need to qualify the claim, for example by naming the setting in which the item breaks down.

Why the word can mislead

• Nearly everything natural eventually breaks down, so the word says little without a timeframe.
• Conditions matter: heat, moisture, oxygen and the right microbes all play a part, and a landfill may lack them.
• A product may be only partly made of biodegradable material.
• The word is not the same as compostable, which refers to a specific composting process and often a specific facility.

How to read a biodegradable label

Look for detail. A trustworthy label explains where and under what conditions the item breaks down, and ideally names a standard or certification that you can look up. A bare biodegradable badge with no explanation is a prompt to ask questions, not an answer. If a seller makes a claim, it is the seller's claim, and you can read the company's product page for evidence.

For products where you actually want a compost outcome, such as plates, cups or bags, the compostable wording and a named certifier are usually more useful than biodegradable. Our related answer explains what compostable means on packaging.

Putting it into practice

Treat the word as a starting point. Compare the claim with how you will dispose of the product, check whether your local program accepts it, and weigh other features such as recycled content or reusability. A reusable item that lasts is often a simpler choice than a disposable one with a degradable claim. Our eco-friendly trash bags and compostable plates guides show how these labels appear on real products.
