Recyclable vs Compostable vs Biodegradable: What Each Term Legally Means

Recyclable means the item can be collected, reprocessed, and used to make something new through an established recycling stream. Compostable means the item breaks down into usable, non-toxic compost within a defined timeframe in a specific type of composting facility, verified against a standard such as ASTM D6400. Biodegradable only means microorganisms will eventually break the material down, with no timeframe, no facility, and no requirement about what is left behind.

Those three definitions are not marketing shades of the same idea. They are legally distinct claims with different evidence requirements under the FTC Green Guides (16 CFR Part 260), and one of them, biodegradable, is banned outright on plastic products in California. This guide covers what each term requires, when each claim is legal on packaging, and how the terms map to what we actually stock.

The line worth memorizing: all compostable packaging is biodegradable, but not all biodegradable packaging is compostable. Compostable is biodegradable plus a deadline, a facility, and a quality bar for the output.

The three claims side by side

The FTC Green Guides were last fully revised in 2012, and the FTC opened a review of them in December 2022 that has not yet produced a new edition. Until it does, the 2012 text is the enforcement baseline, and claims inconsistent with it are prosecutable as deceptive practices under Section 5 of the FTC Act.

Why “biodegradable” is the term to avoid

Biodegradable sounds like the safest, friendliest claim of the three. Legally it is the most dangerous one on packaging, for two reasons.

First, the FTC test is nearly impossible to pass. An unqualified degradable or biodegradable claim requires proof that the entire product completely breaks down and returns to nature within a reasonably short time after customary disposal, and the FTC benchmark is one year. Customary disposal for foodservice packaging is a landfill, an incinerator, or a recycling bin. Nothing meaningfully biodegrades in any of those within a year, so the FTC’s own guidance says unqualified biodegradable claims should not be made for items disposed of that way.

Second, California removed the judgment call entirely. Public Resources Code section 42357, expanded by SB 567 to cover all plastic products effective January 1, 2012, prohibits selling a plastic product in California labeled biodegradable, degradable, or decomposable, or implying in any way that it will break down in a landfill or the environment. There is no qualification that fixes it: for plastics sold into California, the word is simply off the label. A handful of other states restrict degradability labeling as part of their compostable-labeling laws, so multi-state distributors should treat the California rule as the national floor.

This is also why oxo-degradable additives are a supplier red flag. They fragment plastic into microplastics rather than biodegrading it, they cannot meet ASTM D6400, and the marketing built on them is exactly what these statutes target.

What “compostable” legally requires

Compostable is the claim with real teeth behind it, which is what makes it usable. The FTC requires competent scientific evidence that the item breaks down into usable compost in a safe and timely manner. In practice that evidence is a pass against one of two ASTM standards: D6400 for plastics designed to compost in municipal and industrial aerobic facilities, and D6868 for paper and fiber products that carry a plastic coating or additive. D6400 requires disintegration within 84 days and biodegradation within 180 days under industrial composting conditions, plus limits on heavy metals and toxicity in the finished compost.

Third-party certification, most commonly through BPI, is how a buyer verifies the pass without reading lab reports. We cover how that program works, and what the certification mark does and does not guarantee, in the BPI certification guide. California went further with AB 1201 (2021), which requires products sold there with a compostable label to actually meet the applicable ASTM specification and caps total organic fluorine, a PFAS screen, at under 100 parts per million.

Two qualifications still apply even with certification in hand. The ASTM standards assume the sustained heat of an industrial facility, not a backyard pile, so a home-compostable claim needs separate proof. And the FTC requires qualifying the claim if commercial composting facilities are not available to a substantial majority of consumers, which they currently are not in most of the Southeast. Our state-by-state composting infrastructure guide maps where the facilities actually exist, and the compostable materials comparison covers which materials can pass D6400 in the first place.

What “recyclable” legally requires

Recyclable has no product standard to pass. The FTC test is about access: an unqualified recyclable claim is legal only when recycling programs that accept the item are available to a substantial majority of consumers or communities where it is sold, and the FTC defines substantial majority as 60 percent. Below that, the claim must be qualified, down to “recyclable in the few communities with appropriate facilities” when access is minimal.

For our catalog, the recyclable story is PET, resin code 1, the most widely accepted plastic resin in US recycling. The nuance is the format. PET bottles clear the 60 percent access bar comfortably. PET thermoforms, meaning the cold cups and clamshells we stock, are accepted by many curbside programs but not universally, so a qualified claim is the safer label for them. Clear, unpigmented PET has the strongest end-market demand, which is one reason foodservice PET runs clear.

One cross-contamination rule matters at the operator level: compostables do not belong in the recycling bin. PLA looks like PET and ruins PET bales. If you run both streams, bin signage is part of the packaging decision.

How this maps to our stock

The compostable-flagged products in our catalog are the unlined kraft paper lines: SOS bags, twisted-handle shoppers, and liquor bags. Plain kraft is the lowest-risk compostable claim in packaging because there is no coating to fail the test, and it carries a second legal end-of-life story at no extra charge: paper recycling access in the US is broad, so kraft is both recyclable and compostable in most programs.

Kraft is also proof that compostable does not have to mean expensive. From our current pricing: a 16# brown SOS bag runs $14.54 per 500-count case, which is $14.54 divided by 500, or about 2.9 cents per bag. The 20# tall brown SOS is $15.83 per 500, about 3.2 cents. The cheapest compostable unit in the building is the half-pint brown liquor bag at $14.51 per 2000-count case, $14.51 divided by 2000, about 0.7 cents per bag. Going white costs real money: the 16# white SOS at $19.71 per 500 is about 3.9 cents, a penny per bag over brown for the same end-of-life story.

On the recyclable side, the PET lines carry resin code 1: cold cups from 8 oz through 32 oz (a 16 oz PET cold cup with a 92mm rim runs $33.39 per 1000-count case, about 3.3 cents per cup) and hinged PET clamshells from 6 x 6 up to 9 x 9. None of the PET is compostable, and none of it should ever carry a biodegradable label.

Decision cheat sheet

The pattern across all of it: recyclable is a claim about infrastructure, compostable is a claim about the product verified by a standard, and biodegradable is a claim about nothing in particular, which is exactly why regulators treat it as deceptive. If your operation is under a local ordinance or a corporate sustainability mandate, start from what your local facilities actually accept, then buy the claim that matches.
