“Recyclable,” “biodegradable” and “compostable” get used almost interchangeably in packaging marketing, but they describe three different, non-overlapping properties — and mixing them up on a product label is one of the fastest ways to trigger a greenwashing complaint, especially for brands selling into the EU. If you’re briefing a packaging supplier or writing copy for a box, it’s worth knowing exactly what each term means, how it’s certified, and which one actually applies to the materials you’re using.
Recyclable: Depends on Material and Local Infrastructure
“Recyclable” means a material can be collected, processed and remanufactured into new material through existing recycling systems. The catch is that this depends entirely on what facilities exist where the product is sold. Plain paperboard and corrugated card are widely recyclable across the EU, UK, US and Australia. Coated, laminated or foil-backed board is often technically recyclable in theory but rejected in practice by many municipal systems because the coating can’t be separated from the fibre economically. A packaging component is only meaningfully “recyclable” if it’s recyclable in the specific markets you’re claiming it for — a distinction regulators are increasingly strict about.
Biodegradable: A Vague, Often Misleading Claim
“Biodegradable” simply means a material will eventually break down through natural biological processes — but the term carries no defined timeframe or conditions. Almost everything is biodegradable given enough time; the practical question is whether it breaks down in weeks in a home compost bin or over decades in a landfill with no oxygen. Because “biodegradable” has no enforced testing standard behind it in most markets, it’s the claim most likely to be flagged as vague or misleading under the EU’s Green Claims Directive and similar consumer protection rules. If you’re tempted to use it, ask what specific, evidenced claim it’s standing in for — usually you actually mean compostable, and should say so.
Compostable: The Only Term With a Real Certification Standard
“Compostable” is the most specific and defensible of the three, because it’s backed by actual certification standards — EN 13432 in the EU, and BPI/ASTM D6400 in the US. These standards require a material to break down into water, CO2 and biomass within a set timeframe under defined conditions, with no toxic residue. Critically, there’s a difference between industrially compostable (requires the high heat and controlled conditions of a commercial composting facility) and home compostable (breaks down in a standard garden compost bin) — a material certified for one is not automatically certified for the other, and claiming “compostable” without specifying which is itself a common labeling mistake.
Where This Applies to Packaging Materials
- FSC-certified paperboard and kraft board — recyclable through standard paper recycling streams; not compostable if laminated or foil-finished. See our FSC certification guide for how this claim is verified.
- Molded pulp inserts and trays — both recyclable and typically home compostable, making them one of the few packaging components where both claims genuinely apply. Compared in our packaging inserts guide.
- Foil-stamped or laminated board — recyclability drops significantly depending on lamination type; avoid blanket recyclability claims without checking with your supplier.
- PLA-lined or bio-based films — often industrially compostable but not home compostable, and not recyclable in standard paper or plastic streams — a common source of consumer confusion if the packaging isn’t labeled precisely.
Why the Distinction Matters More for EU-Facing Brands
Under the EU’s Packaging and Packaging Waste Regulation (PPWR) and the incoming Green Claims Directive, environmental claims on packaging need to be substantiated and specific, not generic marketing language. A claim like “eco-friendly” or “biodegradable” without supporting evidence is increasingly a compliance risk, not just a marketing choice. Our PPWR compliance guide covers the broader regulatory requirements; the practical takeaway here is to only claim what you can point to a certificate or recycling stream for.
How to Choose the Right Claim for Your Packaging
- Ask your supplier for the specific material composition of every layer — board, coating, lamination, adhesive and ink.
- Check whether each component is recyclable in the specific countries you sell into, not just “recyclable” in general.
- If claiming compostable, confirm whether it’s certified industrial or home compostable, and to which standard (EN 13432 or ASTM D6400/BPI).
- Avoid “biodegradable” as a standalone claim unless you can define the timeframe and conditions.
- Keep certification documents on file — regulators and retailers are increasingly asking for evidence, not just label copy.
