Compostable, Biodegradable, Recyclable: What Each Label Actually Means

Three words show up on almost every foodservice package sold today. Buyers treat them as near-synonyms. Regulators do not — and that gap is where spec sheets go wrong, tenders get challenged, and packaging gets pulled from a menu.

Here is what each label actually requires, taken from the U.S. Federal Trade Commission’s Guides for the Use of Environmental Marketing Claims (the “Green Guides,” 16 CFR Part 260) — the reference text for any environmental claim made to American buyers.

“Biodegradable” is the weakest of the three

The Green Guides address degradable claims, and the guidance applies to the words biodegradable, oxo-degradable, oxo-biodegradable and photodegradable alike (§ 260.8).

The decisive rule is timing and place. The Guides state it is deceptive to make an unqualified degradable claim for items entering the solid waste stream if the items do not completely decompose within one year after customary disposal. They go further: unqualified degradable claims for items customarily disposed of in landfills, incinerators and recycling facilities are deceptive, because those locations do not present conditions in which complete decomposition will occur within one year (§ 260.8(c)).

A material can be genuinely biodegradable in a laboratory and the claim can still be deceptive on a takeaway box — because the box ends up in a landfill.

If a supplier answers “yes, it’s biodegradable” without naming a disposal environment and a time frame, that answer carries no procurement value.

Compostable vs biodegradable: a testable claim, not a synonym

Compostable is not a synonym for biodegradable. It is narrower and testable.

Under § 260.7, a marketer claiming an item is compostable should have competent and reliable scientific evidence that all the materials in the item will break down into, or otherwise become part of, usable compost — soil-conditioning material or mulch — in a safe and timely manner, meaning in approximately the same time as the materials with which it is composted, in an appropriate composting facility or in a home compost pile or device (§ 260.7(b)).

Two qualifications follow automatically:

• If the item cannot be composted safely or in a timely manner in a home compost pile or device, the claim must be clearly and prominently qualified to say so (§ 260.7(c)(1)).
• If municipal or institutional composting facilities are not available to a substantial majority of consumers or communities where the item is sold, the claim must be qualified to disclose that limited availability (§ 260.7(d)).

In practice, “compostable” is shorthand for a specific test standard. Two carry most of the weight in North America:

• ASTM D6400 — Standard Specification for Labeling of Plastics Designed to be Aerobically Composted in Municipal or Industrial Facilities. This is the plastics standard.
• ASTM D6868 — Standard Specification for Labeling of End Items that Incorporate Plastics and Polymers as Coatings or Additives with Paper and Other Substrates Designed to be Aerobically Composted in Municipal or Industrial Facilities.

The second matters enormously for foodservice packaging: most paper and molded-fiber packaging is a composite — a fiber body plus a coating or additive. A fiber bowl with a plastic lining is not “just fiber,” and its claim has to account for every component.

In Europe, the equivalent reference is EN 13432, Requirements for packaging recoverable through composting and biodegradation — Test scheme and evaluation criteria for the final acceptance of packaging, cited as the harmonised standard in EU Commission Decision 2001/524/EC.

“Recyclable” depends on where your customer is, not on the material

Recyclable claims are governed by § 260.12, and the test is access, not chemistry.

A product or package should not be marketed as recyclable unless it can be collected, separated, or otherwise recovered from the waste stream through an established recycling program for reuse or use in manufacturing another item (§ 260.12(a)).

Then the Guides define the threshold: marketers may make an unqualified recyclable claim when recycling facilities are available to a substantial majority of consumers or communities where the item is sold — and “substantial majority,” in this context, means at least 60 percent (§ 260.12(b)(1)). Below that, the claim has to be qualified.

Two further limits catch foodservice packaging specifically:

• If any component significantly limits the ability to recycle the item, any recyclable claim would be deceptive (§ 260.12(d)). A fiber container with a plastic film window is the classic case.
• An item made from recyclable material, but which — because of its shape, size, or some other attribute — is not accepted in recycling programs, should not be marketed as recyclable (§ 260.12(d)).

That is why a technically recyclable food container can still be a non-recyclable product: grease-contaminated fiber is generally not accepted by paper recycling streams, and small items fall through sorting equipment. On the operational question — what happens to the box — compostable often outperforms recyclable.

Certification removes a claim’s ambiguity, not your obligation

Third-party certification is the practical way to substantiate these claims. But the Green Guides are explicit: third-party certification does not eliminate a marketer’s obligation to ensure it has substantiation for all claims reasonably communicated by the certification (§ 260.6(c)). It is also deceptive to imply that a product has been endorsed or certified by an independent third party when it has not (§ 260.6(a)).

So a logo is evidence, not immunity. You still need to know what the certificate covers — which product, which standard, which disposal environment.

Six questions to ask before you specify packaging

1. Which standard? “Compostable” alone is not an answer. Ask for the standard number and which version.
2. Industrial or home? They are different claims with different qualification duties.
3. Does the claim cover the whole item? Including coatings, linings, windows and adhesives.
4. What is your disposal environment? Landfill, commercial compost, home compost, paper recycling — each breaks a different claim.
5. Which body issued the certificate? And is it current?
6. Which SKUs does it cover? Certification is granted per item, not per company.

What this means for your specification

Molded fiber is usually chosen because it avoids the plastic-coating problem: a bagasse container is formed from sugarcane fiber under heat and pressure, so there is no polyethylene film to disqualify the claim. But “fiber” alone does not settle it — if a coating or lid film is part of the item, the composite rule applies and the standard may shift from D6400 to D6868.

Two pages on our site are worth reading before you commit to a spec: our packaging materials guide compares kraft paper and bagasse, and our certifications page sets out the compliance documentation we hold.

If you need the standard, the certificate and the covered SKU list in writing, talk to us about your spec.

The short version

• Biodegradable describes a process with no defined time or place. Unqualified, it is legally exposed and commercially meaningless.
• Compostable is a testable performance claim, tied to a specific standard and a specific disposal environment. This is what makes compostable vs biodegradable a decidable question.
• Recyclable is an access claim. The material can qualify and the product still cannot.

If a supplier can answer all six questions above in writing, you are dealing with a documented claim. If they answer with a word, you are dealing with marketing.
