Walk down any supermarket aisle and you'll spot a green leaf, a recycling arrow, or the word "compostable" on packaging more often than not. It looks reassuring. The trouble is, these terms get used almost interchangeably by brands even though they mean genuinely different things, and in the UK, that gap between claim and reality has become significant enough that DEFRA received over 4,000 consumer complaints about misleading environmental claims between 2024 and 2025 alone.
So what does "home compostable" actually mean, how is it different from "industrially compostable" or simply "biodegradable," and how do you tell a genuine claim from a green-washed one? Here's the full picture.
Home Compostable vs Industrial Compostable: The Difference That Actually Matters
This is the single most important distinction, and the one most packaging labels blur.
Industrial composting facilities operate at controlled temperatures of around 55 to 70°C, with regular aeration and monitored humidity, conditions no back garden compost heap can replicate. Packaging certified only for industrial composting is designed around those conditions specifically. Put it in your own compost bin at home, where temperatures typically sit at a much gentler 20 to 30°C, and it can sit there for months or years without meaningfully breaking down.
Genuinely home compostable packaging is tested and certified to break down under those cooler, ambient home conditions instead, with at least 90% of the material required to degrade within 12 months in a standard home compost environment. That's a materially different (and harder) standard for a material to meet, which is exactly why relatively few packaging types actually qualify for it.
The practical takeaway: if packaging is only labelled "compostable" with no further detail, assume it means industrially compostable unless stated otherwise. Very few UK households have access to industrial composting facilities, so in practice that packaging is likely headed for general waste regardless of the label.
What About "Biodegradable" and "Recyclable"?
These two get folded into the same conversation constantly, but neither means the same thing as home compostable.
"Biodegradable" is the vaguest of the terms. It has no legally defined timeframe or testing standard attached to it in most contexts, technically, almost everything is biodegradable eventually, including conventional plastic, just potentially over hundreds of years. A label that only says "biodegradable" tells you almost nothing useful about how long it will actually take to disappear or under what conditions.
"Recyclable" is a different claim entirely: it means a material can theoretically be reprocessed into something new, not that it breaks down naturally. Many supplement tubs run into a practical problem here too. Even if the main tub is technically recyclable, the lid, scoop, and inner seal are frequently made from different plastic types that most kerbside recycling schemes can't sort or process together, so the whole unit often ends up in general waste in practice, recyclable claim notwithstanding.
The Certification That Actually Means Something: OK Compost HOME
Given how loosely these terms get used, the only reliable way to verify a genuine home compostable claim is via third-party certification, and the benchmark here is TÜV Austria's OK compost HOME scheme.
Established in 2003, it was the first certification of its kind anywhere, and it's since formed the basis for several national standards, including Australia's AS 5810 and France's NF T51800. To earn it, a product must meet the baseline EN 13432 standard and then pass additional testing specific to home conditions: biodegradation testing at 20 to 30°C, disintegration testing to confirm it physically breaks into small fragments rather than persisting as visible plastic, and ecotoxicity testing to confirm nothing harmful is released into the soil as it breaks down.
If packaging carries this certification (look for the OK compost HOME seal specifically, not just a generic leaf icon or the word "eco" printed somewhere), you have genuine, tested assurance it will do what it claims in an ordinary home compost bin.
The Bioplastic Trap: Why "Plant-Based" Doesn't Mean Home Compostable
One of the most persistent sources of confusion is PLA, a bioplastic derived from plant sources like corn starch, widely marketed as an eco-friendly plastic alternative. It sounds like it should compost easily at home. It doesn't.
PLA only breaks down under genuine industrial composting conditions. In a landfill, or in an ordinary home compost bin, it behaves essentially like conventional plastic, with some estimates suggesting it can take anywhere from 100 to 1,000 years to decompose in those environments. The deeper problem is infrastructure: the vast majority of PLA packaging never actually reaches an industrial composting facility in the first place, so despite the "plant-based" framing, most of it ends up doing exactly what regular plastic does, sitting in landfill or contaminating recycling streams it was never designed for.
This is precisely why material matters as much as the compostable claim itself. Paper-based packaging doesn't rely on specialised industrial infrastructure to break down; it's a simple, well-understood material that composts under genuinely ordinary conditions, which is a meaningfully different proposition to a bioplastic that only works under conditions most of it will never actually reach.
Why This Has Become Such a Hot Topic in 2024–2025
Regulators and retailers have started catching up with this confusion. UK Trading Standards audits found that more than 60% of biodegradable product claims reviewed were non-compliant or lacked credible supporting evidence. In response, major UK retailers have tightened their requirements: Tesco now requires third-party certification for any biodegradability or compostability claim on products it stocks, and Co-op specifically demands TÜV OK Compost or EN 13432 verification before allowing the word "compostable" on packaging at all. WRAP, the UK's Waste and Resources Action Programme, has also published formal guidance aimed at reducing exactly this kind of consumer confusion.
In short, the packaging industry is being pushed toward the same standard consumers should already be applying themselves: don't take "eco" claims at face value, look for the certification behind them.
How to Actually Compost Home Compostable Packaging
If you've got genuinely certified home compostable packaging, using it correctly helps it break down as intended:
Tear or shred it into smaller pieces before adding it to your compost bin or heap. Smaller surface area means the microorganisms responsible for breaking it down can work through it faster. If there's any tape, label, or sticker on it that isn't part of the certified material itself, remove that first, as it likely won't compost with the rest.
Home compostable packaging generally counts as a "brown" (carbon-rich) material, so balance it with "green" nitrogen-rich waste like vegetable peelings or grass clippings for a healthy compost mix. And be patient: even genuinely home compostable material can take several months, and sometimes closer to a year, to fully disappear, particularly in a cooler or less actively managed compost heap.
If you don't have a home compost bin, check whether your council's food or garden waste collection accepts certified home compostable packaging, many now do, though it's worth confirming locally rather than assuming.
Where CHOOZY Fits In
We built our Creapure® Creatine Monohydrate packaging around the genuine, certified end of this spectrum rather than the marketing end. Our 5g sachets and 500g pouch are made from home-compostable paper, not a PLA or bioplastic blend relying on industrial infrastructure most people can't access, and the pouch comes with a stainless steel 5g scoop rather than a plastic one, so nothing about the format depends on a "compostable" plastic claim that may or may not hold up. CHOOZY is currently the only brand worldwide offering genuinely plastic-free, home compostable packaging for Creapure® creatine, across both sachet and 500g pouch formats.
Rather than just describing our packaging as "eco-friendly" and hoping you'll take our word for it, CHOOZY is TÜV Austria OK compost HOME certified, the same rigorous, independently tested standard described above. Even the seals on our pouches are made from a plant-based, vegetable-derived material rather than plastic film, so there's no hidden plastic layer left behind once the paper itself has broken down. It's paper and plant-based material, all the way through: something that breaks down the way it's supposed to, in an ordinary compost bin, without needing a specialist facility to do it.
This same standard runs across the whole range, not just creatine. Our electrolytes and magnesium glycinate are also packaged in entirely plastic-free, home compostable packaging, so the same certification and reasoning applies whichever CHOOZY product you're taking daily.
FAQs
Is compostable the same as biodegradable?
No. Biodegradable has no defined timeframe or testing standard and can technically apply to materials that take centuries to break down. Certified compostable packaging must meet specific, tested standards for how completely and how quickly it breaks down.
Can I put home compostable packaging in my recycling bin?
No, it should go in your compost bin, food waste caddy, or garden waste collection where accepted, not general recycling, as it isn't designed to be reprocessed the way recyclable materials are.
How long does home compostable packaging actually take to break down?
Certified home compostable packaging must degrade by at least 90% within 12 months in home compost conditions, though in practice it's often faster, especially for paper-based materials.
Is "compostable" packaging mostly just greenwashing?
Not if it's genuinely certified, but a lot of packaging on the market uses the word loosely without third-party certification behind it, which is why regulators and major UK retailers have started requiring proof like OK compost HOME or EN 13432 certification before allowing the claim at all.
What happens if compostable packaging ends up in landfill by mistake?
Even genuinely compostable materials break down far more slowly, or not meaningfully at all, in landfill conditions, which lack the oxygen and microbial activity composting relies on. Composting it properly, rather than binning it, is what allows it to break down as intended.
Are the seals on paper pouches secretly still plastic?
Often, yes, which is one of the more common ways "compostable" packaging quietly falls short. CHOOZY's pouch seals are made from a plant-based, vegetable-derived material rather than plastic film, so there's no hidden layer left behind after composting.
