9 Greenwash Tricks on Packaging (And How to Beat Them)

Most "Eco" Packaging on the Australian Market Is Not What It Claims to Be

A 2021 study by the European Commission found that 53% of green claims on consumer products were vague, misleading, or unsubstantiated. Australia has no reason to believe its packaging sector performs better. Walk through any food service trade show, browse any wholesale catalogue, and you'll find dozens of products labelled "eco-friendly", "green", "earth-conscious", "natural", or "sustainable" — with zero certification to back them up.

For a café owner, hospitality manager, sustainability officer, or council procurement team, this isn't just frustrating. It's a compliance risk. Buying packaging that claims to be compostable but isn't certified means your waste contractor may reject it, your FOGO bin may be contaminated, and your customers may feel misled. Worse, under the Australian Consumer Law (ACL), making false or misleading environmental claims can expose your own business to liability — not just your supplier's.

This article is a working reference for anyone who needs to cut through the noise. We'll cover exactly how greenwashing works in the packaging industry, what the real certification standards require, how to read a product spec sheet, and what questions to ask any supplier before signing a purchase order.

What Greenwashing Actually Looks Like in Packaging

Greenwashing in packaging isn't always a blatant lie. It's more often a carefully crafted half-truth — a word chosen because it sounds positive but carries no legal or technical definition. Here are the nine most common tactics used in the Australian market, ranked from the most obvious to the most subtle.

1. "Biodegradable" Without a Timeline or Condition

Technically, almost everything is biodegradable given enough time — including a plastic bag in 400 years. When packaging is labelled simply "biodegradable" with no certification, no conditions, and no timeline, it tells you almost nothing useful. In Australia, there is no mandatory legal definition for the term "biodegradable" on packaging. Any supplier can print it on a box and face no regulatory consequence.

What you need to see instead: a specific standard, a certified decomposition timeline, and the conditions required (industrial composting facility, home compost, soil, marine environment). Without those three elements, "biodegradable" is marketing copy, not a claim.

2. "Plant-Based" or "Natural" Materials Without Certification

PLA (polylactic acid) is made from corn starch or sugarcane. It sounds natural. But standard PLA requires an industrial composting facility operating at 55–60°C for 90+ days to break down. Throw it in a home compost bin, a FOGO bin that doesn't accept unverified packaging, or — worse — general waste, and it behaves essentially like conventional plastic for decades.

"Plant-based" describes the feedstock, not the end-of-life behaviour. Buyers must treat these two properties as completely separate questions.

3. Green Colouring, Leaf Logos, and Nature Imagery

This is the most visual form of greenwashing and the easiest for consumers to be fooled by. Brown kraft-look containers, green ink, leaf motifs, and imagery of forests or oceans signal "eco" without making any verifiable claim. No standard is cited. No certification body is referenced. The packaging looks sustainable because the designer made it look sustainable.

4. Vague Certifier Names or Invented Logos

Some suppliers create proprietary "eco" logos that look official but are self-issued. Others reference certifiers that aren't accredited by the relevant Australian or international bodies. In Australia, legitimate compostable certification must be issued by an accredited third-party body — the two most recognised are Australasian Bioplastics Association (ABA) and SEEDLING (DIN CERTCO / TÜV Austria) for industrial composting, and ABA Home Compostable or OK Compost HOME for home composting.

5. "Recyclable" Claims Without Kerbside Qualification

A packaging item may technically be recyclable in a laboratory or at a specialist facility — but if your local council's kerbside system doesn't accept it, it goes to landfill. The APCO (Australian Packaging Covenant Organisation) Australasian Recycling Label (ARL) is the benchmark here. Products certified with the ARL state clearly whether they are kerbside recyclable, store drop-off only, or not recyclable. Without the ARL, "recyclable" is an incomplete claim.

6. Partial Compostability — the Lid Problem

One of the most common gotchas in food service packaging: a container body is certified compostable under AS 4736, but the lid is not. Or the sleeve is bagasse, but the liner contains a fossil-fuel-based polymer that won't break down. The entire assembly must be certified for the claim to hold. Always ask: "Is the complete unit — body, lid, liner, and any adhesive or coating — certified to the same standard?"

7. Oxo-Degradable or Oxo-Fragmentable Plastics

These are conventional plastics with a chemical additive that causes them to fragment into microplastics when exposed to UV light or heat. They are not compostable, not biodegradable in any meaningful sense, and are now banned or being phased out in the EU and in several Australian state bans. They are, however, still sold in Australia and sometimes marketed as "degradable" or "eco" packaging. If you see a product described as "oxo-degradable", "oxo-biodegradable", or "UV-degradable" — avoid it entirely.

8. "Compostable" Without Specifying Industrial vs Home

This is the subtlest and most consequential distinction in the entire compostable packaging category. AS 4736 (industrial composting) and AS 5810 (home composting) are two entirely different standards with different temperature requirements, different timeframes, and different acceptance in council FOGO programs. A product certified only to AS 4736 cannot go in a home compost bin. If your waste stream goes to a domestic composting system — or to a council FOGO program that doesn't run at industrial temperatures — that certification is irrelevant.

9. Inflated Recycled Content Claims

"Made with recycled materials" can mean 5% post-consumer recycled content blended with 95% virgin polymer. Without a percentage figure and an explanation of what "recycled" means (post-consumer vs post-industrial), the claim is meaningless. Look for specific percentages and ask whether the recycled content affects food safety certification.

The Real Standards: What Certified Compostable Actually Means in Australia

Australia has two primary national standards for compostable packaging, plus a labelling standard that governs how claims can be made on-pack. Understanding all three is non-negotiable for any serious buyer.

AS 4736 — Industrial Composting

AS 4736-2006 is the Australian Standard for biodegradable plastics suitable for composting and other microbial treatment. Products certified to this standard must:

• Disintegrate by at least 90% within 12 weeks at 58°C (±2°C)
• Achieve at least 60% biodegradation (conversion to CO₂) within 180 days
• Leave no more than 10% of original dry weight as residue after sieving
• Demonstrate no negative effect on the composting process or resulting compost quality
• Meet ecotoxicity requirements — the resulting compost must not inhibit plant growth
• Contain no more than specified limits of heavy metals and fluorine

This standard requires conditions only achievable in an industrial composting facility: sustained high temperatures, controlled humidity, turning schedules, and microbial populations. Products certified to AS 4736 should carry the Australian Bioplastics Association (ABA) seedling logo or equivalent accredited certification mark.

AS 5810 — Home Composting

AS 5810-2010 is significantly more demanding than AS 4736 because home compost environments are far less controlled. Products certified to this standard must break down under ambient temperature conditions (20–30°C), with no artificial microbial inoculation, and within a timeframe comparable to organic food waste. The certification is rarer and more expensive to achieve, but it's the only standard that genuinely supports household composting claims.

For businesses whose customers compost at home — farmers markets, organic retailers, zero-waste households — AS 5810 certification is the meaningful benchmark. For industrial food service operations feeding into a commercial composting facility, AS 4736 is sufficient.

AS 4631 — Labelling of Compostable Plastics

AS 4631-2020 governs how compostable packaging must be labelled. It requires that any on-pack claim include clear identification of which composting pathway is appropriate (home or industrial), the relevant standard number, and the name of the certifying body. A product that simply says "compostable" without this detail is not compliant with AS 4631 — and that non-compliance is itself a warning sign.

How These Standards Relate to State Bans

Australia's state-based single-use plastics bans have created a patchwork of requirements that interact directly with these standards:

• NSW: Phase 1 commenced 1 November 2022 (lightweight plastic bags, plastic straws, cutlery, plates, cotton bud sticks, stirrers). Phase 2 commenced 1 November 2023. Expanded provisions covering produce bags and additional items continue to roll out through 2025–2026.
• QLD: Single-use plastic bans have been implemented in stages from 2021, with expanded items including PVC cling wrap and further containers.
• VIC: Victoria's ban commenced 1 February 2023 and covers straws, cutlery, plates, drink stirrers, and expanded polystyrene food containers.
• SA: South Australia was the earliest mover, with initial bans dating to 2009 and continuous expansion since, including banning lightweight bags in 2011 and further items including plastic-coated paper plates.
• WA: Western Australia's ban commenced 1 January 2023 covering straws, cutlery, plates, drink stirrers, and polystyrene containers.
• ACT: The ACT has implemented bans aligned with national targets, with continued expansion into 2025.
• TAS: Tasmania's ban on single-use plastic items commenced in 2023.

Critically, these bans do not automatically mean that alternatives must be compostable — they must simply not be single-use plastic. But buyers who want to make genuine environmental claims need to go further than merely avoiding banned materials.

How to Interrogate a Supplier: The 7-Question Protocol

When evaluating any packaging supplier's environmental claims, these seven questions should be non-negotiable. A legitimate supplier will answer every one of them directly. Evasion, redirection to marketing materials, or vague responses are red flags.

1. "What is the certification standard number and who issued it?" — You want AS 4736 or AS 5810, issued by ABA, DIN CERTCO, or TÜV Austria. Not a proprietary logo, not a self-certification.
2. "Does the certification cover the complete unit — body, lid, liner, and any adhesive?" — The full assembly must be certified, not just the dominant component.
3. "What composting pathway does your product require?" — Industrial only? Home? Soil biodegradation? This determines which waste stream it can enter.
4. "Can you provide a copy of the certification document?" — Legitimate certifications are documented. If a supplier can't provide it within 24 hours, it likely doesn't exist.
5. "Is your product accepted in FOGO programs?" — This is a practical, real-world question. The correct answer is nuanced: "It depends on the council and their composting contractor." Any supplier who says "yes, everywhere" is overstating.
6. "Does your product contain any fossil-fuel-derived polymers, OXO-additives, or PFAS coatings?" — PFAS (per- and polyfluoroalkyl substances) are being phased out globally due to toxicity concerns. Some compostable packaging still uses PFAS-based grease-resistant coatings. Ask explicitly.
7. "What percentage of your product range carries third-party certification?" — This reveals whether sustainability is core to the business or a marketing overlay on a conventional packaging catalogue.

At ZenPacks, our full range of 700+ eco products is sourced specifically to meet these criteria. We can provide certification documentation for every product in our range.

FOGO Programs, Council Acceptance, and What It Means for Your Business

FOGO (Food Organics and Garden Organics) bin programs are expanding rapidly across Australian councils, driven by federal targets to halve food waste by 2030 under the National Food Waste Strategy. For food service businesses, FOGO programs create a genuine composting pathway for certified packaging — but the rules are inconsistent and matter enormously when buying packaging.

Which Councils Accept Compostable Packaging in FOGO?

There is no single national rule. Each council contracts with a composting facility, and that facility sets the acceptance criteria. In general terms:

• Councils using in-vessel composting at industrial temperatures will typically accept AS 4736-certified packaging.
• Councils using windrow composting may only accept AS 5810 (home compostable) items or no packaging at all.
• Some councils specifically list accepted brands or certification marks on their websites. City of Sydney, for example, has published guidance on FOGO-accepted compostable packaging categories.
• Packaging must always be food-soiled (i.e., used) or empty — clean packaging often goes to general recycling, not FOGO.

The practical advice for any food business: check with your specific local council before making any claims to customers about composting. Don't print "compostable — put in FOGO bin" on your packaging unless you've confirmed your local council's acceptance criteria in writing.

APCO 2025 National Packaging Targets

The Australian Packaging Covenant Organisation (APCO) set targets for 2025 requiring that 100% of packaging be reusable, recyclable, or compostable. These targets apply to signatories of the covenant and are informing regulatory direction across all states. For procurement teams at councils and large organisations, these targets mean that packaging specifications in tenders and supplier agreements should now reference APCO alignment as a minimum baseline.

Reading a Product Spec Sheet: What the Numbers Actually Mean

Beyond the certification question, a product's technical specifications tell you whether it will actually perform in your application. Here's how to interpret the key data points on a compostable packaging spec sheet.

Material Composition

• Bagasse (sugarcane pulp): The fibre left after sugarcane juice extraction. Naturally grease-resistant, microwave-safe to approximately 120°C, oven-safe to 220°C for short periods. Certified compostable under both AS 4736 and, for uncoated products, often AS 5810. Best for: hot food containers, plates, bowls, clamshells.
• PLA (polylactic acid): A bioplastic derived from corn or sugarcane starch. Transparent or translucent. Cold applications only — begins to deform above 40–45°C. Certified to AS 4736. Not suitable for hot beverages. Best for: cold cups, lids on cold beverages, deli containers, salad bowls.
• CPLA (crystallised PLA): Heat-treated PLA with higher temperature resistance — typically to 85–90°C. Used for hot cup lids, cutlery, and straws. Certified to AS 4736. Best for: coffee cup lids, hot beverage accessories.
• Kraft paper with compostable liner: FSC-certified paper with a PLA or other compostable inner coating rather than fossil-fuel PE. Certified to AS 4736. Critical question: confirm the liner is compostable, not conventional PE. Best for: hot cups, soup cups, noodle boxes.
• Bamboo: Fast-growing grass, naturally antimicrobial. Uncoated bamboo items are often home compostable. Best for: cutlery, plates, skewers.
• Moulded fibre / recycled paper pulp: Made from recycled paper or agricultural fibre. Often AS 4736 certified. Best for: egg trays, food trays, bowl liners.

Temperature Ratings — The Most Commonly Misunderstood Spec

"Hot food safe" is not a single number. Ask specifically about:

• Fill temperature: The temperature of the food or liquid at the time of filling. Bagasse containers handle direct fills up to 95–100°C. PLA containers should not be filled with anything above 40°C.
• Microwave safety: Bagasse is microwave-safe (without metallic coatings). PLA is not microwave-safe. CPLA is typically not recommended.
• Oven safety: Bagasse containers are typically oven-safe for warming (not cooking) up to 200–220°C for periods under 30 minutes. No compostable plastic (PLA, CPLA) is oven-safe.

Grease and Liquid Resistance

Uncoated bagasse is naturally grease-resistant due to the density of the fibre structure. Kraft paper requires a liner or coating for liquid or grease resistance — and that coating must be compostable for the product to be genuinely certified. Ask specifically whether the coating is PFAS-free (some legacy products still use fluorinated coatings). The industry is moving toward water-based barrier coatings and PLA liners as PFAS-free alternatives.

The Original Framework: The 4-Point Compostable Packaging Verification Checklist

This framework is designed to be used at the point of supplier evaluation. It can be embedded in procurement policies, tender specifications, or supplier onboarding checklists. We developed it for use across food service, hospitality, and public sector procurement.

Step 1 — Claim Verification: Identify the exact environmental claim made. Map it to a specific Australian Standard (AS 4736, AS 5810) or recognised international equivalent (EN 13432, ASTM D6400). If no standard is cited, treat the claim as unverified.

Step 2 — Certifier Verification: Identify the certifying body. Confirm it is an accredited third party (ABA, DIN CERTCO, TÜV Austria, BPI). Search the certifier's public database for the specific product or product family. Most legitimate certifiers maintain searchable registers.

Step 3 — Assembly Verification: Confirm that every component of the product as used (body + lid + liner + any closure) carries the same certification. Request a certification scope document if the supplier cannot answer verbally.

Step 4 — Pathway Verification: Confirm which composting pathway is required. Map that against your actual waste infrastructure — your council's FOGO program, your commercial composting contractor, or your customers' home composting capability. If the pathway doesn't exist in your context, the certification is irrelevant to your environmental outcome.

Businesses that want to present a credible sustainability profile — whether for council tender requirements, ESG reporting, or customer-facing marketing — should document this verification for every product in their packaging inventory. If you're setting up or refreshing your food business's online presence to communicate your sustainability commitments, platforms like weauto — professional websites for Australian businesses from $99 make it straightforward to publish your verified packaging policy in a way that builds customer trust.

What's Changing in 2026–2027: Where the Regulation Is Heading

The regulatory environment for packaging claims is tightening in Australia, and buyers who understand what's coming can get ahead of compliance requirements rather than scrambling to catch up.

ACCC Greenwashing Enforcement

The Australian Competition and Consumer Commission (ACCC) has made environmental claims a priority enforcement area. In 2023–2024, the ACCC conducted a greenwashing internet sweep across 247 businesses and found that 57% raised concerns — including vague claims, unclear conditions, and lacking substantiation. Enforcement actions and guidance documents have followed. For food businesses making claims about their packaging on websites, menus, and signage, this has direct implications: claims must be accurate, qualified, and substantiatable.

National Packaging Reforms

Australia's post-2025 packaging policy framework is expected to move toward mandatory product stewardship for packaging, extended producer responsibility (EPR), and potentially mandatory minimum recycled content requirements. The direction is toward a circular economy model where packaging producers bear greater responsibility for end-of-life outcomes. Buyers who are already specifying certified compostable or genuinely recyclable packaging will be better positioned as these obligations cascade down supply chains.

FOGO Rollout Acceleration

The federal government's commitment to halving food waste by 2030 is accelerating FOGO rollout across councils that have not yet implemented it. As FOGO becomes ubiquitous, the value of certified compostable packaging increases — because the composting pathway finally exists at scale for most food businesses. This is the single most important structural change coming for the compostable packaging category in the next three years.

PFAS Restrictions

Regulatory restrictions on PFAS in food contact materials are advancing globally and will arrive in Australia. Buyers who proactively specify PFAS-free packaging now — and document that specification — will avoid a mandatory transition later. Ask every supplier explicitly: "Does this product contain any per- or polyfluoroalkyl substances in any component?"

Frequently Asked Questions

Is compostable packaging really compostable?

Certified compostable packaging — carrying AS 4736 or AS 5810 certification from an accredited third-party body — is genuinely compostable under the conditions specified. The critical caveat is "under the right conditions": AS 4736 products require an industrial composting facility operating at 55–60°C; they will not break down in home compost, landfill, or the ocean. If a product claims to be compostable without referencing a specific standard or certifying body, that claim should be treated as unverified.

What is the difference between AS 4736 and AS 5810?

AS 4736 is the Australian Standard for industrial composting — products must disintegrate within 12 weeks and biodegrade within 180 days at temperatures of 58°C, conditions only achievable in a commercial composting facility. AS 5810 is the home composting standard — products must break down at ambient temperatures (20–30°C) comparable to the speed of food waste in a backyard compost bin. AS 5810 is the harder standard to meet and is certified to fewer products. If your customers compost at home, AS 5810 is the relevant standard.

Can you put compostable cups in FOGO bins?

It depends entirely on your local council's FOGO program and their composting contractor's acceptance criteria. Some councils accept AS 4736-certified packaging in FOGO; others do not. You must confirm with your specific council before advising customers to place compostable cups in FOGO bins. Placing non-accepted packaging in FOGO bins causes contamination that can result in entire loads being sent to landfill — the opposite of the intended outcome.

How can I tell if packaging is genuinely compostable or greenwash?

Look for four things: (1) a specific Australian Standard number (AS 4736 or AS 5810); (2) the name of an accredited certifying body (ABA, DIN CERTCO, TÜV Austria); (3) the recognised certification logo (ABA Seedling, OK Compost); and (4) clear indication of whether industrial or home composting is required. If any of these four elements is missing, request documentation from the supplier. If documentation cannot be provided, the claim is unverified.

Are oxo-degradable plastics the same as compostable?

No — they are fundamentally different and should not be confused. Oxo-degradable plastics are conventional fossil-fuel plastics with a chemical additive that causes them to fragment into microplastics under UV or heat exposure. They do not biodegrade in any meaningful sense and are considered harmful by most environmental scientists. They are banned or being phased out in multiple jurisdictions. Oxo-degradable products are not compostable and should not be used as a sustainability solution.

Does "plant-based" mean compostable?

No. "Plant-based" refers to the feedstock used to make the material (e.g., corn starch, sugarcane, bamboo) and says nothing about end-of-life behaviour. Standard PLA is plant-based but requires industrial composting conditions to break down; in a home compost bin or landfill, it behaves similarly to conventional plastic. Always evaluate plant-based claims and compostability claims as separate, independent properties.

What does APCO's 100% packaging target mean for my business?

APCO's 2025 target — that 100% of packaging be reusable, recyclable, or compostable — is a voluntary commitment for APCO signatories but is increasingly influencing procurement requirements in councils, government contracts, and corporate supply chains. If you supply into institutional channels (hospitals, schools, councils, large hospitality groups), you may face supplier questionnaires that reference APCO alignment. Specifying certified compostable or ARL-labelled recyclable packaging for your entire product range positions you to answer these requirements confidently.

Is PLA packaging accepted in kerbside recycling?

No. PLA is not accepted in Australian kerbside recycling streams. It is not compatible with conventional plastic recycling processes and, if mixed in, contaminates recyclable PET and other streams. PLA must go to an industrial composting facility (if AS 4736 certified), or — in the absence of that pathway — it goes to general waste. This is one of the most important practical limitations of PLA-based packaging and underscores why the composting infrastructure question is inseparable from the packaging choice question.
