Packaging that says “eco-friendly,” “biodegradable,” or “compostable” sounds reassuring, but these words are not interchangeable and they are not just marketing flavor — each one carries a specific legal meaning under FTC rules and, for compostable claims, specific ASTM test standards behind it.
This guide breaks down what each term actually requires, how they differ in practice, and what brand owners need to check before printing any of these claims on a package.
Quick Answer
Recyclable means a material can realistically be collected and reprocessed into new products through existing recycling programs. Compostable means a material breaks down into usable, non-toxic compost within a defined timeframe under specific composting conditions, verified by testing. Biodegradable means something breaks down into natural elements, but an unqualified biodegradable claim legally requires proof that the entire item fully decomposes within about a year of how it’s normally thrown away — a bar that packaging headed for a landfill almost never clears, which is why the FTC treats unqualified biodegradable claims as a red flag.
What Each Claim Requires
Recyclable, under the FTC’s Green Guides (16 CFR Part 260), can only be claimed without qualification when recycling facilities are available to a “substantial majority” of consumers or communities where the product is sold — the FTC’s benchmark for that is at least 60%. If access falls below that, the claim has to be qualified, for example “recyclable only in select areas” or “check locally.” A chasing-arrows symbol alone does not satisfy this; the material also has to actually get collected and reprocessed in practice, not just be technically capable of it.
Compostable claims require competent, reliable evidence that the material will break down into usable compost, safely and within a similar timeframe to other compostable materials in the same disposal system — industrial facility, municipal program, or home compost pile. In the US, the de facto proof points are third-party certification against ASTM D6400 (for compostable plastics and bioplastic films) or ASTM D6868 (for compostable coatings and linings on paper or fiber packaging), most commonly verified through the Biodegradable Products Institute (BPI) certification mark. A product that is only “industrially compostable” cannot be marketed as compostable without saying so, since most consumers don’t have access to industrial composting.
Biodegradable claims are the strictest to make without qualification, not the loosest: under 16 CFR 260.8, an unqualified claim needs competent and reliable scientific evidence that the entire item will completely decompose into elements found in nature within a reasonably short period after customary disposal — and the FTC’s own guidance treats anything longer than about one year as deceptive. Because most packaging is customarily disposed of in landfills, incinerators, or recycling facilities — none of which provide the oxygen, moisture, and microbial activity needed for that kind of breakdown within a year — an unqualified “biodegradable” claim on ordinary packaging is one of the clearest examples the FTC has flagged as potentially deceptive. Any claim that can’t meet that one-year, complete-decomposition bar has to be qualified with the specific environment and realistic timeframe instead.
How the Three Terms Differ in Practice
Recyclable is about reprocessing into new material — glass, aluminum, and many plastics and papers can be recyclable, but only if local programs actually collect that specific material. Compostable is about biological breakdown into soil-safe compost under managed conditions, which is why BPI-certified items are meant for compost bins, not recycling bins or random outdoor disposal. Biodegradable is a physical/chemical breakdown claim with a specific legal bar attached — complete decomposition within about a year of customary disposal — and when a product can’t meet that bar in its real-world disposal environment, the claim must be qualified rather than left general.
A practical gap to watch: a product can be compostable and still not be recyclable (putting a BPI-certified cup in a recycling bin can contaminate a recycling stream), and a product can pass a generic biodegradability lab test without qualifying for an unqualified “biodegradable” claim, because that claim demands a specific timeframe and disposal-environment match that lab tests alone don’t guarantee. Mixing these claims up on packaging, or implying one covers the other, is one of the more common greenwashing mistakes regulators and plaintiffs’ attorneys look for.
Tips / Common Mistakes
Don’t rely on a chasing-arrows symbol or a plant icon alone — always pair the claim with the qualifying detail (e.g., “recyclable where facilities exist” or “commercially compostable, not in all communities”). Keep documentation on hand: BPI certification paperwork or ASTM test reports for compostable claims, and data on local recycling access for recyclable claims, since the FTC expects claims to be substantiated before they’re printed, not after a complaint. Avoid unqualified “biodegradable” on anything destined for a landfill — if the product can’t be shown to fully decompose within about a year under its actual disposal conditions, qualify the claim with the real disposal environment and realistic timeframe instead. Finally, remember these claims are evaluated per material component, not per package as a whole — a package with a recyclable paper body and a non-recyclable plastic window needs to disclose that distinction rather than claim the whole package is recyclable.

Biodegradable vs compostable vs recyclable labeling FAQs
Can a package be both compostable and recyclable?
Not in the same stream. A package can offer one disposal path or the other, but compostable items should not go in recycling bins (they can contaminate the recycling stream) and recyclable items should not go in compost bins. If a package has multiple components, each one needs its own accurate claim.
Is BPI certification required to say ‘compostable’?
Not legally required, but it’s the most widely recognized way to substantiate the claim in North America. Without third-party certification against ASTM D6400 or D6868, a company needs its own competent, reliable test evidence to back up a compostable claim if challenged.
Why is ‘biodegradable’ considered risky to use on packaging?
Because an unqualified biodegradable claim legally requires proof that the item will completely decompose within about a year of how it’s normally disposed of, and most packaging ends up in a landfill, where that kind of breakdown within a year generally doesn’t happen. Regulators have repeatedly treated unqualified biodegradable claims on landfill-bound packaging as misleading for exactly this reason.
