Compostable Packaging Labels: What's Actually Required

Why Compostable Packaging Labels Are a Legal and Commercial Minefield

A compostable label on packaging isn't just a marketing badge — in Australia, it's a regulated claim governed by Australian Standards, state-level single-use plastics legislation, and emerging national product stewardship frameworks. Get it wrong and you're exposed to two distinct risks: regulatory non-compliance that can attract fines, and greenwashing liability under the Australian Consumer Law (ACL), which the ACCC has been enforcing with increasing aggression since 2023.

This article sets out exactly what labelling requirements apply to compostable packaging in Australia — which standards must be met, what claims are permissible, how state bans interact with certification, and what your packaging must physically display before it can legally be called "compostable." Whether you're a hospitality operator buying in bulk, a packaging buyer specifying SKUs, or a sustainability officer auditing your supply chain, this is the reference you'll need to cite.

The Three Standards That Govern Compostable Claims in Australia

Australia uses three primary standards to regulate what can and cannot be called compostable. These are not interchangeable — each covers a different end-of-life pathway, and a product certified to one standard cannot lawfully claim compliance with another.

AS 4736-2006: Industrial (Commercial) Compostability

AS 4736-2006 is the benchmark standard for packaging intended for industrial composting facilities — the large-scale, temperature-controlled operations that process commercial food waste, FOGO collections, and commercial organic streams. To carry a compliant claim under this standard, a product must demonstrate:

• Biodegradation of at least 90% of organic material within 180 days under controlled composting conditions (58°C ± 2°C)
• Disintegration: at least 90% of material passes through a 2mm sieve within 12 weeks
• No ecotoxicity: the resulting compost must not adversely affect plant growth
• Hazardous substance limits: heavy metals and other regulated substances must not exceed prescribed thresholds
• Volatile solids content of at least 50%

Products certified under AS 4736 are typically made from bagasse (sugarcane pulp), PLA (polylactic acid), CPLA, bamboo fibre, or kraft paper with compostable liners. Industrial composting is the intended disposal pathway — these products should not be represented as suitable for home compost heaps.

AS 5810-2010: Home Compostability

AS 5810-2010 is the stricter standard, because home compost conditions are far less controlled than industrial facilities. Temperatures in backyard compost bins typically range from 20°C to 30°C — far below the 58°C threshold used in AS 4736 testing. Products certified under AS 5810 must biodegrade under these lower-temperature conditions within the same 180-day timeframe.

In practice, very few food service packaging items carry AS 5810 certification. The material science is more demanding: most PLA-based products will not pass AS 5810 because PLA requires the elevated temperatures of industrial composting to break down. Packaging claiming "home compostable" without AS 5810 certification is a common — and legally problematic — greenwashing scenario.

AS 4631: Compostable Labelling Requirements

AS 4631 is the standard that directly governs how compostable claims must be displayed on packaging. It specifies that any packaging making a compostable claim must:

• State which composting pathway is applicable (industrial or home)
• Reference the relevant Australian Standard (AS 4736 or AS 5810) or an equivalent internationally recognised certification
• Carry the certification body's mark (e.g., the Australasian Bioplastics Association seedling logo, or CEIF/TÜV marks where applicable)
• Not use language that implies a broader or faster decomposition than the standard supports

AS 4631 is the standard most commonly violated in practice. Businesses importing packaging from offshore — particularly lower-cost PLA items from Asia — frequently find that products carry European EN 13432 certification but no Australian Standard mark. While EN 13432 is technically equivalent in scientific requirements to AS 4736, Australian regulators and councils do not always accept it as proof of compliance without additional documentation.

The Australasian Bioplastics Association (ABA) Certification Mark

In practice, the most recognised certification pathway for Australian-market compostable packaging is third-party certification through the Australasian Bioplastics Association (ABA). The ABA administers a seedling-style logo program — a stylised green seedling mark — that appears on packaging certified to AS 4736 (industrial) or AS 5810 (home compostable).

The ABA mark is what most Australian councils, waste processors, and FOGO program operators look for when determining whether packaging can be accepted in organic waste streams. It is also the mark that satisfies the ACCC's requirement for substantiated environmental claims under the Australian Consumer Law — more on that below.

What the Mark Must Include

A correctly applied ABA certification mark on compostable packaging must display:

1. The ABA seedling logo in its approved form (not modified or reproduced informally)
2. The words "Industrially Compostable" or "Home Compostable" adjacent to or within the mark
3. The certification number issued by ABA (this allows the product to be verified in the ABA's public register)
4. The applicable standard reference: AS 4736-2006 or AS 5810-2010

If your supplier cannot provide the ABA certification number, or if the packaging simply says "compostable" with a generic leaf logo, that product does not meet Australian labelling requirements and should not be represented as certified compostable packaging.

Australian Consumer Law: The Greenwashing Dimension

Beyond the technical standards, compostable packaging labels must also comply with the Australian Consumer Law (ACL), specifically sections 18 and 29 which prohibit misleading and deceptive conduct and false representations. The ACCC's 2023 greenwashing guidance explicitly names environmental claims — including "compostable," "biodegradable," and "eco-friendly" — as high-risk claim categories.

What the ACCC Now Expects

The ACCC's updated guidance (published January 2023) requires that environmental claims on packaging must be:

• Accurate and specific: "Certified industrially compostable under AS 4736" is acceptable. "Eco-friendly" without qualification is not.
• Substantiated: Claims must be backed by a current, verifiable third-party certification — not a supplier's self-declaration.
• Qualified where necessary: If packaging is only compostable in industrial facilities, the label must make this clear. A claim of "compostable" without qualification implies it will break down in any composting environment, which is false for most PLA products.
• Not misleading by omission: Stating a product is "made from plants" without disclosing that it will not break down in a home compost or landfill setting can constitute misleading conduct.

The ACCC has already pursued action against businesses in the energy, fashion, and household goods sectors. The food packaging sector is a logical next target given the volume of unsubstantiated "compostable" and "biodegradable" claims on the market.

State and Territory Plastic Ban Legislation: Labelling Intersections

Australia's wave of single-use plastics bans — rolled out state by state since South Australia's pioneering legislation in 2009 — has created a patchwork of requirements that interact directly with compostable packaging labelling. Understanding these intersections is critical, because a product that is labelled "compostable" but doesn't meet the relevant standard may still be banned under state legislation.

The key insight from this table: in every Australian state and territory, certification to AS 4736 or AS 5810 is the gateway to compostable exemption status under single-use plastics bans. Packaging that claims to be compostable but lacks this certification does not qualify for an exemption — meaning it may be banned, even if it is genuinely compostable by some measure.

FOGO Programs and the Acceptance Question

Food Organics and Garden Organics (FOGO) bin programs are now rolling out across Australia as councils work toward the National Waste Policy Action Plan's target of halving food waste by 2030. FOGO acceptance of compostable packaging is one of the most misunderstood areas in the entire compostable packaging conversation.

Not All Certified Products Are Accepted in All FOGO Bins

This is the point that catches most hospitality operators off guard. A product can be legitimately certified to AS 4736, carry the ABA mark, and still be rejected by a specific council's FOGO program. Why? Because FOGO processors — the commercial composting facilities that handle council organic waste — set their own acceptance criteria based on their equipment, processing times, and end-product quality requirements.

Many processors operate on 6-8 week composting cycles for council FOGO material, which may be insufficient for some certified compostable packaging items that technically pass the 180-day AS 4736 test. Processors also have to consider contamination risk: if consumers put non-certified "biodegradable" plastics into FOGO bins alongside certified compostable items, the whole batch can be compromised.

How to Check Your Local Council's Acceptance Policy

Before communicating to your customers that your packaging can go in the FOGO bin, verify directly with your local council. As a general guide:

• Accepted by most FOGO programs: ABA-certified bagasse plates and containers, certified kraft paper bags, certified paper-lined cups without plastic lids
• Variable acceptance: Certified PLA cups and lids (many processors reject these due to contamination risk from conventional PLA which looks identical)
• Rarely accepted: Home compostable film and bags in FOGO (designed for home compost, not high-temperature industrial processing)
• Not accepted: Products claiming compostability without ABA certification or AS 4736/AS 5810 certification documentation

For businesses operating across multiple postcodes — food delivery platforms, catering companies, franchise groups — this variability means you cannot make a single blanket statement about FOGO disposal on your packaging. The safest approach is to label packaging with "Certified Industrially Compostable (AS 4736)" and direct consumers to check local council guidelines, rather than asserting "put this in your green bin."

Physical Labelling Requirements: What Must Appear on the Packaging

Pulling together the requirements from AS 4631, the ABA certification program, ACL compliance, and state plastic ban legislation, here is the minimum information that compliant compostable packaging should display:

Mandatory Elements

1. Compostability claim: "Certified Industrially Compostable" or "Certified Home Compostable" — not just "compostable" without qualification
2. Applicable standard: AS 4736-2006 (industrial) or AS 5810-2010 (home)
3. Certification body mark: ABA seedling logo (or recognised equivalent such as TÜV Austria OK compost marks)
4. Certification number: Verifiable in the ABA public register
5. Disposal guidance: Brief instruction on correct disposal pathway ("Industrial compost facility" or "Home compost")

Recommended Additional Elements

• Material composition (e.g., "Made from sugarcane bagasse" or "PLA lined kraft paper")
• Temperature rating if relevant to food service (e.g., "Suitable for food up to 100°C")
• Statement that the item is not suitable for recycling streams
• Manufacturer or supplier name and country of origin (required under Australian Consumer Law for most packaged goods)

What NOT to Include

• The recycling triangle (chasing arrows) symbol on compostable packaging — this creates consumer confusion and may constitute misleading conduct under ACL
• Vague terms like "eco-friendly," "green," or "planet-friendly" without substantiation
• Claims that the product will break down in landfill — certified compostable products typically will not, and such claims are both false and potentially in breach of ACL
• "Biodegradable" used as a synonym for "compostable" — these are distinct technical terms with different standards

APCO National Packaging Targets and What They Mean for Labelling

The Australian Packaging Covenant Organisation (APCO) National Packaging Targets set an ambitious benchmark: by 2025, 100% of packaging used in Australia should be reusable, recyclable, or compostable. While APCO membership and compliance is voluntary for most businesses below a certain threshold, the targets are driving significant change in how packaging is specified, labelled, and recovered.

APCO's framework requires that packaging claiming compostability must meet the recognised Australian Standards. APCO signatories — which include major food manufacturers, retailers, and packaging brands — are required to report annually on the percentage of their packaging that is certified compostable and the end-of-life pathways available to consumers.

For food service operators, the APCO targets create indirect pressure: your packaging suppliers are increasingly required to demonstrate certified compostability as part of their own APCO reporting. This is one reason the market has shifted toward properly certified products, and why the volume of uncertified "biodegradable" packaging in the supply chain is decreasing — though it hasn't disappeared.

2026–2027 Outlook: What's Changing

The labelling landscape for compostable packaging in Australia is not static. Several significant regulatory and market developments are expected over the next 12–24 months that every packaging buyer should be monitoring.

Mandatory Labelling Under State Plastic Bans

New South Wales Phase 2 of the Plastic Reduction and Circular Economy Act (effective 1 November 2025) extends restrictions to additional single-use plastic item categories including some types of produce bags and expanded polystyrene containers. Suppliers and retailers in NSW will face tighter requirements to demonstrate that compostable alternatives are genuinely certified — not just labelled — before they qualify as compliant substitutes.

ACCC Greenwashing Enforcement

The ACCC's stated enforcement priorities for 2024–2025 include environmental claims in the consumer goods sector. Expect to see formal investigations and potentially prosecutions in the packaging space within the next 12–18 months. Businesses should audit their packaging claims now rather than wait for a compliance notice.

Standardised Disposal Icons

Work is underway through the Australasian Recycling Label (ARL) program — administered by Planet Ark and APCO — to develop standardised compostability disposal icons that can sit alongside the existing ARL recycling icons. Once finalised, these icons are expected to become the default consumer-facing disposal guidance on certified compostable packaging, replacing the current patchwork of certification marks and text instructions. Businesses that update their packaging to include ARL-compatible icons early will have a compliance advantage.

Digital Passport Requirements

The EU's Digital Product Passport (DPP) regulation — which requires packaging to carry a scannable code linking to full material and certification data — is being watched closely by Australian regulators. While Australia has not yet committed to a DPP equivalent, major importers and retailers are beginning to request QR codes linking to certification documentation on compostable packaging. If you're specifying packaging for supply to large retailers or institutions, building this capability now is advisable.

If you're building out your business's sustainability credentials online — including a packaging compliance page, supplier certification library, or FOGO guidance for customers — having a professional web presence matters. weauto offers professional websites for Australian businesses from $99, which is a practical starting point for food businesses that need to communicate their compostable packaging policies clearly to customers and councils.

Practical Checklist: Auditing Your Current Packaging for Compliance

Use this checklist to assess whether your current compostable packaging labels meet Australian requirements. It applies whether you're buying direct from a supplier, importing, or reviewing packaging from an existing stock.

1. Certification mark present? — ABA seedling logo or equivalent third-party mark (TÜV Austria OK Compost, Din Certco)
2. Standard cited? — AS 4736-2006 (industrial) or AS 5810-2010 (home) referenced on the packaging
3. Certification number verifiable? — Check the ABA public register at bioplastics.org.au
4. Disposal pathway specified? — "Industrial compost facility only" or "Home compost" clearly stated
5. No recycling symbol? — Confirm the chasing arrows triangle does not appear on compostable items
6. No unsubstantiated claims? — Remove or qualify any use of "eco-friendly," "green," "planet-safe" without certification backing
7. Country of origin? — Required for most packaged goods under ACL
8. Supplier documentation? — Obtain and file the current certification certificate from your supplier — this is your evidence if ACCC or council audits your claims

Frequently Asked Questions

Is compostable packaging really compostable in Australia?

Certified compostable packaging — carrying the ABA seedling mark and certified to AS 4736 or AS 5810 — is genuinely compostable under the right conditions. The key qualification is which conditions: most certified products require industrial composting at sustained high temperatures (55–65°C), not a backyard compost bin. Products certified to AS 5810 will break down in home compost. Uncertified products claiming to be compostable without a recognised standard may not break down at all within practical timeframes.

What is the difference between AS 4736 and AS 5810?

AS 4736-2006 covers industrial (commercial) compostability — products must break down at 58°C in a controlled composting environment within 180 days. AS 5810-2010 covers home compostability — products must break down at lower ambient temperatures (around 20–30°C) within the same 180-day timeframe. AS 5810 is the stricter standard because it requires biodegradation without the elevated temperatures that industrial facilities provide. Most food service packaging is certified to AS 4736, not AS 5810.

Can you put compostable cups in FOGO bins?

It depends on your local council and their processing facility. Certified compostable cups made from bagasse or kraft paper are accepted by most Australian FOGO programs. PLA and CPLA cups and lids — even when AS 4736 certified — are rejected by many FOGO processors because they are visually indistinguishable from conventional plastic and pose a contamination risk. Always check with your specific council before advising customers to place compostable cups in the FOGO bin.

Does European certification (EN 13432) satisfy Australian requirements?

EN 13432 is the European equivalent of AS 4736 and applies equivalent scientific testing thresholds. In practice, many Australian councils and state regulators accept EN 13432 certified products as compliant, particularly when accompanied by ABA registration or TÜV Austria OK Compost certification. However, it is safest to source packaging with ABA certification specifically, as this is the mark Australian councils, waste processors, and regulators are trained to recognise. Some state enforcement frameworks explicitly reference Australian Standards rather than European equivalents.

What happens if my packaging says "compostable" but isn't certified?

Under the Australian Consumer Law, making an unsubstantiated environmental claim — including a compostable claim without certification — constitutes misleading conduct under sections 18 and 29 of Schedule 2 of the Competition and Consumer Act 2010. Penalties for businesses include fines and corrective advertising orders. Additionally, uncertified "compostable" packaging does not qualify as a compliant alternative under state single-use plastics bans, meaning you may still be in breach of those regulations even if the product is genuinely compostable by some measure.

Do I need to label each individual item, or just the outer case?

For retail-ready and consumer-facing food service packaging, the compostability claim and certification mark should appear on the item itself or on the individual packet (e.g., the wrapper on a cutlery kit, or printed on the cup or container). Bulk outer carton labelling alone is not sufficient for consumer-facing compliance under the ACL, because the claim must be visible to the end user at the point of disposal. For wholesale-only bulk goods that are never seen by consumers, outer carton labelling with accompanying certification documentation is generally acceptable.

Can I use the word "biodegradable" instead of "compostable" on packaging?

"Biodegradable" and "compostable" are distinct claims with different technical and regulatory meanings. In Australia, there is no single standard for biodegradability claims on packaging (unlike compostability, which has AS 4736 and AS 5810). Using "biodegradable" without qualification is considered a vague environmental claim and is flagged as high-risk under the ACCC's greenwashing guidance. If your packaging is certified compostable, use "compostable" with the appropriate standard reference — don't substitute "biodegradable" as it implies a broader and often misleading set of end-of-life outcomes.

What records should I keep as a food business using compostable packaging?

Keep on file: the current ABA or equivalent certification certificate for each packaging SKU you use, the supplier's product specification sheet confirming the applicable standard, and any correspondence with your council or waste processor confirming FOGO acceptance. If the ACCC or a state environmental regulator asks you to substantiate your compostable claims, these documents are your primary evidence. Review your certifications annually — they have expiry dates, and a lapsed certification makes your packaging claims non-compliant even if the product itself hasn't changed.
