Compostable, recyclable, biodegradable. They get used almost interchangeably on packaging, as though they’re three ways of saying the same thing. They’re not. Each one describes a completely different process, with a different outcome, and mixing them up is exactly how a lot of “eco” packaging ends up in landfill anyway.
Recyclable
Recyclable means a material can be processed and remade into something new, but only if it actually reaches the right facility. Not all recyclable materials are accepted by all councils, and contamination (food residue, mixed materials, small pieces that fall through sorting machinery) sends plenty of technically recyclable packaging straight to landfill regardless. Recyclable is a claim about the material’s properties, not a guarantee about what actually happens to it after it leaves your bin.
Biodegradable
Biodegradable means a material will eventually break down through natural biological processes. It says nothing about how long that takes or what conditions it needs. Technically, almost everything is biodegradable given enough time, including materials that will still be around long after everyone reading this is gone. Without a timeframe and a defined set of conditions attached, “biodegradable” is one of the least meaningful words on any package.
Home Compostable
Home compostable is the specific one. It means a material breaks down in a standard backyard compost bin or heap, under normal home conditions, within a defined and reasonably short timeframe. This is a far higher bar than biodegradable, and a different bar than industrially compostable, which requires the high heat and controlled conditions of a commercial facility that most councils in Australia don’t provide kerbside access to.
Why the Difference Actually Matters
A box marked “compostable” that actually needs an industrial facility you can’t access does the same thing a box marked “recyclable” does when your council won’t take it: it ends up in general waste, label notwithstanding. The label wasn’t dishonest exactly, it was just missing the one detail that determines whether the claim means anything to the person holding the box.
Home compostable removes that gap. If it breaks down in your own backyard, the claim doesn’t depend on facilities, council programs, or contamination sorting. It depends on dirt, which everyone has access to. That’s the packaging standard we build to, and why we say “home compostable” specifically rather than the vaguer “eco-friendly” or “biodegradable.” You can read the full reasoning behind that choice in Why We Chose Home-Compostable Over Recyclable Packaging.
Checking a Claim for Yourself
If a label says compostable without specifying home or industrial, that’s worth a follow-up question. If a label says biodegradable without a timeframe, that’s a marketing word wearing a science word’s coat. If a label says recyclable, it’s worth checking whether your actual council accepts that specific material, because “recyclable” and “accepted by your local council” are two different facts.

Frequently Asked Questions
What’s the difference between compostable and biodegradable?
Biodegradable just means something will eventually break down naturally, with no defined timeframe. Compostable means it breaks down within a specific timeframe under specific conditions, which is a much more precise and useful claim.
What’s the difference between home compostable and industrially compostable?
Home compostable breaks down in a standard backyard compost bin under normal home conditions. Industrially compostable requires the high heat and controlled environment of a commercial composting facility, which most Australian councils don’t provide kerbside access to.
Does recyclable packaging always get recycled?
Not necessarily. Whether recyclable packaging actually gets recycled depends on whether your local council accepts that specific material and whether it’s free of contamination. Being technically recyclable doesn’t guarantee it reaches a recycling facility.
Why is “home compostable” a more useful claim than “eco-friendly”?
Home compostable is specific and testable, you can put it in your own backyard compost and check. “Eco-friendly” has no fixed meaning and can’t be verified the same way.
Real talk.
Recyclable, biodegradable, compostable. Three different words, three different processes, and only one of them (home compostable) actually tells you what happens without needing a council program or an industrial facility to back it up.
Read the label properly. The difference is usually in the word they left out.
