A wholesale supplier's plain-English guide for cafe owners who want to get their sustainability claims right.
Your takeaway cups have "compostable" printed on the side. Your customers love it. Your barista mentions it when handing over a flat white. And somewhere in the back of your mind, a small voice asks: what does that word actually mean, and could the ACCC come knocking?
It's a fair question. In Australia, "compostable" isn't a single thing. It's a category that commonly involves two different standards, two very different disposal pathways, and a growing regulatory spotlight on environmental claims. If you run a cafe, this is worth ten minutes of your time — because the gap between "what the cup says" and "where the cup actually ends up" is exactly where greenwashing risk lives.
Here's the plain version.
1. Why "Compostable" Isn't One Thing
When a product is labelled "compostable" in Australia, it usually points to one of two standards:
- AS 4736:2006 — Industrial Compostable. This standard is built around the conditions you find in a professional commercial composting facility: sustained temperatures of roughly 55–70°C, controlled moisture, regular turning, and an industrial process timeline. It's a hot, fast, managed environment.
- AS 5810:2010 — Home Compostable. This one is built around what you'd find in a backyard compost bin: lower temperatures, slower biological activity, no industrial controls. The bar is significantly higher because the conditions are less forgiving.
The important thing to understand is that "compostable" on a label doesn't automatically equal either of these standards. Genuine compliance depends on the specific certification mark and the body that issued it — in Australia, the recognised certifier is the Australasian Bioplastics Association (ABA). A product without that certification is using the word "compostable" descriptively, not as a verified claim.
In the cafe supply market, PLA-lined cups and similar bioplastic-coated products are more commonly certified to AS 4736 (industrial) than to AS 5810 (home). That distinction matters, because it determines where the cup needs to go to actually compost.
Here's the customer trap: a well-meaning regular sees "compostable," takes their empty cup home, and tosses it into their backyard compost bin. In home composting conditions, an AS 4736 cup typically won't break down as expected — performance is significantly weaker than in an industrial setting it was designed for. The cup just sits there, intact.
From the ACCC's perspective, labelling something "compostable" without clarifying which standard and which disposal pathway is exactly the kind of claim that struggles to meet the "evidence-supported" bar.
2. The Bin Reality — Where Your Cup Actually Ends Up
Let's follow a typical takeaway cup after a customer is done with it.
The most relevant pathway for compostable packaging is the FOGO stream — Food Organics and Garden Organics — which some councils now collect kerbside in a separate bin. But FOGO access in Australia varies enormously by state and by council. Some metropolitan areas have well-established FOGO programs with mature processing. Others have nothing yet, and many sit somewhere in between with partial rollouts or pilot programs.
Even where FOGO exists, whether PLA or AS 4736–certified packaging is accepted depends on the specific council. Many councils explicitly do not accept bioplastic packaging in their FOGO stream — even if the cup is certified to AS 4736 — because their processing facilities aren't set up for it, or because contamination from look-alike non-compostables makes the stream unviable.
When a council doesn't accept PLA, the practical outcome is straightforward: the cup goes to landfill. Same destination as a conventional PE-coated cup. The certification on the label doesn't change the physical endpoint.
On-site composting at cafes is rare. The vast majority of Australian cafes do not operate a dedicated organics stream. Anything not taken away by customers ends up in general waste.
The net effect: a cup labelled "compostable" that doesn't have a viable composting pathway in its actual environment is, in practical terms, performing the same as a regular cup — just with a more sustainable-sounding label. This is precisely the disconnect that draws regulatory attention.
3. The ACCC View on Environmental Claims
The ACCC has been steadily increasing its focus on environmental claims in recent years. The underlying principle is simple but strict: any "green" claim a business makes must be supportable by evidence, and it must not mislead consumers.
"Greenwashing" — vague, abstract, or unsupported environmental language — is the central risk area. Terms like eco-friendly, compostable, sustainable, planet-friendly used without specifics, qualifications, or disposal pathways are high-risk territory.
For cafes, the practical risk point is this: if your website, menu, or signage says "all our cups are compostable" — but your local council doesn't accept PLA in FOGO, and your cafe has no on-site organics stream — that statement is hard to support with evidence. The cups could compost in the right facility, but the customer in front of you has no realistic way to get them there.
A safer alternative is specific and conditional. Something like:
"Our cups are AS 4736 industrial compostable, accepted by selected councils. Please check your local kerbside collection guidelines."
That's a claim you can actually back up. It names the standard, it acknowledges the limitation, and it puts useful information in front of the customer.
The bottom line: specific, verifiable, conditional claims are far stronger than blanket "eco" labels — both ethically and from a regulatory exposure standpoint.
4. Three Compliant Cafe Strategies
Different cafes have different priorities — cost sensitivity, brand positioning, customer demographics. Here are three approaches that hold up to scrutiny.
Strategy A — Aqueous Coated, recyclable pathway. Skip the compostable claim entirely and lean into recyclability. Aqueous-coated cups can carry the Australasian Recycling Label (ARL) and are accepted in standard yellow recycling bins in most areas. This is the lowest-risk path: the claim is concrete, the disposal pathway is widely available, and ACCC compliance is straightforward as long as the ARL is on the packaging.
Strategy B — PLA Coated with AS 4736, honestly labelled. For cafes whose brand story leans heavily on sustainability and who are willing to do the customer-education work, PLA with AS 4736 certification is a legitimate option. The key is honest labelling: "AS 4736 industrial compostable — dispose in commercial compost stream where available." This requires staff training so baristas can answer questions, and ideally some in-store signage explaining what that means. Works well for specialty cafes with engaged customers.
Strategy C — Mixed approach. Use aqueous-coated cups for everyday SKUs (cost-effective, low compliance risk) and reserve PLA for a small premium or single-origin line where the sustainability narrative adds genuine value. The trick is to keep marketing language disciplined: don't make blanket "our cafe is environmentally friendly" statements that cover everything. Speak to each product line on its own terms.
5. The Customer-Facing Communication
How you talk about your cups matters as much as which cups you stock.
In-store signage — A specific statement like "Our cups are recyclable in [council] yellow bins" is dramatically more useful — and more defensible — than a vague "Our cups are eco-friendly." Specifics beat abstractions every time.
Menu footnotes — One small line explaining your cup type signals transparency and builds trust. Customers respect honesty more than they respect green branding.
Reusable cup discounts — Offering 50 cents off for customers who bring their own cup is the single highest-impact sustainability action a cafe can take. It's a genuine environmental win, and it's not a regulatory risk because it's a verifiable behaviour, not a claim about a product.
Social media — Skip the "our cups save the planet" language. Write something like "We offer a reusable cup discount and follow our local FOGO guidelines." That's a statement you can back up.
Watch the visuals too. Abstract leaf icons, green earth motifs, and sustainability imagery without specific underlying claims can fall under "visual greenwashing" — the ACCC has signalled that misleading impressions can come from images and design choices, not just words.
6. Sourcing Checklist — What to Ask Your Wholesale Supplier
When you're talking to a supplier about compostable or eco-credentialed cups, these are the questions worth asking:
- Which Australian Standard does this product certify against? (AS 4736, AS 5810, or something else?)
- Do you have the certificate from a recognised body? Specifically, the Australasian Bioplastics Association (ABA) for compostable products.
- What is the recommended disposal pathway in my region? A good supplier should know the basics of FOGO acceptance by major councils.
- What's the ARL marking on the packaging? This is the simplest, most consumer-friendly recycling signal.
- Are there alternative options if I can't access industrial composting locally? This is the question that separates suppliers who understand the practical reality from those who are just selling labels.
At Pakio, our BioPak, PLA, and Aqueous Coated product lines are tagged with their specific certifications at the SKU level, and full certification documentation is available on request. If you'd like to walk through which approach makes sense for your cafe, get in touch.
Where This Leaves You
"Compostable" printed on a cup isn't the end of the conversation — from the ACCC's perspective, it's the start of one. Which standard? Which disposal stream? Does your local council accept it? How are you telling customers what to do with it?
The three strategies above — aqueous recyclable, PLA AS 4736 with honest labelling, or a mixed approach — each have their place. What they share is a single principle: specific claims, supporting actions, and evidence you can show if asked.
Pakio supplies AS 4736–certified, aqueous-coated, and recyclable cup ranges, with full certification documentation available for every SKU. If you want to tighten up your sustainability story for the new financial year, reach out — we'll match SKUs to your operational reality, not just to the words on the label.
