AS4736 Certified? 5 Tests Packaging Must Actually Pass

The 5 Lab Tests That Define AS 4736 Certification

AS 4736-2006 is Australia's industrial composting standard, and it is one of the most rigorous biodegradability frameworks in the Asia-Pacific region. Every product sold with an AS 4736 certification has been independently tested against five specific, measurable criteria — not submitted for review by the manufacturer or self-declared on a data sheet. That distinction matters enormously when you're sourcing packaging for a food business, catering operation, or institution where waste-stream compliance and sustainability reporting are non-negotiable.

The standard is administered under the Australian Standards system, with its testing protocol grounded in ISO 14855 (biodegradation) and ISO 16929 (disintegration) methodologies. Third-party certification is carried out by recognised bodies including the Australasian Bioplastics Association (ABA), TÜV Austria via its OK Compost Industrial programme, and DIN CERTCO in Germany. Products that pass all five criteria earn the right to display the certification logo — and, in Australia, to be genuinely marketed as certified compostable packaging rather than simply claimed to be.

Here is what those five tests actually require:

Test 1: Biodegradation Rate (≥90% within 180 Days)

The product must convert at least 90% of its organic carbon into CO₂ within 180 days when exposed to active composting microorganisms in a controlled laboratory environment. Testing is conducted at 58°C ± 2°C — the sustained temperature of a functioning industrial compost pile. This is a chemical mineralisation test, not a visual appearance check. A product that fragments into small pieces but has not mineralised chemically fails this criterion regardless of how degraded it looks.

Test 2: Disintegration (≥90% through a 2mm Screen within 12 Weeks)

Physical fragmentation is assessed separately from chemical biodegradation. At least 90% of the material by dry weight must pass through a 2mm mesh screen within 12 weeks under active composting conditions. This prevents visual contamination of finished compost — large fragments of nominally compostable packaging in compost output create a quality problem for composting operators and an enforcement problem for the entire certification system. Composters routinely reject loads contaminated with non-compliant fragments.

Test 3: Ecotoxicity (No Inhibition of Plant Growth)

Compost produced using 10% by weight of the test material must support plant germination and growth at rates equivalent to a blank compost control — with no statistically significant difference in seed germination rates or plant biomass across the trial. This is the criterion most eco marketing completely ignores. A product could technically biodegrade and disintegrate while leaving behind breakdown compounds that suppress plant growth or contaminate agricultural soil. The ecotoxicity test catches exactly this scenario. It is why the word compostable under AS 4736 means more than simply breaks down.

Test 4: Heavy Metals and Regulated Substances Below Threshold

The material must contain lead, cadmium, copper, zinc, nickel, mercury, chromium, molybdenum, selenium, and arsenic at concentrations below the maximum thresholds set out in AS 4736. These thresholds align with those in the European EN 13432 standard and are enforced because compost derived from contaminated packaging would ultimately enter food-growing soils. Packaging with heavy pigments, metallic inks, or certain adhesive formulations frequently fails this test when assessed as a complete, finished product rather than as a raw substrate material.

Test 5: The Entire Product — Not Just the Base Material

This is the criterion most packaging buyers are unaware of, and it has the most practical implications for procurement. AS 4736 certification applies to the complete product configuration as sold — including coatings, inks, liners, adhesives, lids, mechanical clips, and any insert components. A bagasse container that is independently AS 4736 certified is not automatically certified when sold with a PLA window insert, a foil heat seal, or a non-certified liner. Each product configuration and product code must be tested and certified separately. When a supplier changes a component — even switching an ink colour or adding a logo print — the certification status of that specific configuration may need to be re-evaluated.

How to Verify an AS 4736 Certification Claim Before You Order

The Australian market contains a meaningful proportion of packaging products sold with compostable or AS 4736-equivalent language that have never been independently tested. This is not always deliberate fraud — some products genuinely meet the performance criteria but have not pursued formal certification. However, for FOGO bin acceptance, supplier compliance audits, and any formal sustainability reporting, only independently certified products count. Here is how to verify a claim in under five minutes, using what packaging buyers in the industry call the 3-Document Rule.

The 3-Document Rule: when sourcing certified compostable packaging at wholesale, always request three documents from your supplier — (1) the Certificate of Conformity listing the specific product code, (2) the test report summary confirming results against each of the five AS 4736 criteria, and (3) the certification body's current accreditation confirmation. Any supplier who cannot provide all three within 24 hours is operating without complete certification documentation, regardless of what their catalogue says.

Step 1: Look for a Recognised Certification Logo

Four certification marks are currently recognised in Australia for compostable packaging compliance:

• ABA Certified Compostable (Industrial) — administered by the Australasian Bioplastics Association, tested specifically to AS 4736. This is the primary Australian mark.
• TÜV Austria OK Compost INDUSTRIAL — tested to EN 13432, the European technical equivalent of AS 4736. Widely recognised by Australian councils and composting facilities.
• DIN CERTCO / DIN-Geprüft Compostable — European certification, tested to EN 13432. Equivalent in scope and threshold requirements to AS 4736.
• BPI Certified Compostable — North American certification, tested to ASTM D6400. Generally accepted in Australia but confirm acceptance with your specific composting facility before specifying.

A product with none of these marks and only the word compostable printed on it has made a marketing claim, not a certified one. Logo presence is the fastest first filter — if it's not there, ask for documentation before proceeding.

Step 2: Search the Certified Products Database

The Australasian Bioplastics Association maintains a searchable registry of certified products at bioplastics.org.au. You can search by product type, material, manufacturer, or brand name. TÜV Austria maintains its own database for OK Compost certified products, searchable by brand and product code. Before placing any bulk order for a product you haven't previously verified, spend two minutes in one of these databases. If a supplier's product is not listed and they cannot explain why — for instance, because they hold certification under a different certifying body — request the certificate directly.

Step 3: Request the Certificate of Conformity

A current Certificate of Conformity from a legitimate certified product will show:

• The specific product name and product code (must match the item you're ordering exactly)
• The certifying body — ABA, TÜV Austria, DIN CERTCO, or BPI
• The standard tested against — AS 4736, EN 13432, or ASTM D6400
• The certification issue date and expiry date (typically valid for three years)
• The complete product configuration covered, including liners, lids, coatings, and any accessory components

An expired certificate means the product is no longer certified, even if it was fully compliant at the time of testing. Certification must be renewed through periodic retesting. Keep copies of current certificates on file — FOGO programme auditors and sustainability assessors may request them.

Step 4: Red Flags That Signal an Unverified Claim

These phrases appearing on packaging or in supplier catalogues should prompt an immediate verification request before you commit to an order:

• "Biodegradable" without a certification logo — biodegradable is not the same as certified compostable
• "Compostable under the right conditions" — a hedge that signals uncertified material
• "Meets AS 4736 requirements" — self-declared; independent verification has not occurred
• "Eco-friendly" or "environmentally friendly" with no specific standard cited
• "Breaks down naturally" — legally meaningless in the context of AS 4736
• A certification logo without an accompanying certification code or product registration number
• A certification logo that does not match any of the four recognised bodies listed above

AS 4736, AS 5810, Biodegradable, and Conventional Plastic — What the Data Shows

Packaging buyers in 2026 face a market with at least four distinct categories of product marketed under sustainability claims, each with fundamentally different performance characteristics, certification requirements, and composting infrastructure needs. This table cuts through the marketing language:

Feature	AS 4736 Certified (Industrial Compostable)	AS 5810 Certified (Home Compostable)	"Biodegradable" (Uncertified)	Conventional Plastic
Australian Standard	AS 4736-2006	AS 5810-2010	None	N/A
Composting environment required	Industrial facility (58°C+)	Home bin (<30°C ambient)	Unknown — varies by material	Does not compost
Biodegradation target	≥90% in 180 days	≥90% in 365 days	No defined requirement	400–1,000+ years
Independent third-party testing	Mandatory	Mandatory	Not required	N/A
Ecotoxicity tested	Yes	Yes	No	N/A
Heavy metals tested	Yes	Yes	No	N/A
FOGO bin acceptance	Accepted by most FOGO councils	Limited — check locally	Not accepted	Not accepted
State single-use plastics ban compliance	Qualifies as compliant alternative	Qualifies as compliant alternative	Varies by state — check regulations	Banned categories: banned
APCO 2025 packaging target eligible	Yes	Yes	No	Counts as non-compliant waste
Typical wholesale cost premium vs plastic	10–40%	15–60%	Variable	Baseline

One important nuance that the table cannot fully capture: AS 5810 (home compostable) is in several respects a more demanding standard than AS 4736, not a lower one. It requires biodegradation at ambient household temperatures — far below the 58°C of industrial composting — which means fewer materials can qualify. Most PLA-based packaging passes AS 4736 but fails AS 5810 because PLA requires sustained high heat to break down. Home compostable products are therefore not a tier below industrial compostable — they serve a different disposal pathway and face stricter ambient-temperature conditions.

Which Australian Councils Accept AS 4736 Certified Packaging in FOGO Bins

The most consequential waste infrastructure change in Australian local government right now is the accelerating rollout of FOGO — Food Organics and Garden Organics — kerbside collection. Under Federal support for the National Food Waste Strategy and state government FOGO mandates, the majority of metropolitan councils are expected to operate FOGO services by 2027. Whether certified compostable packaging can go into these bins depends entirely on the policies of each specific council — and those policies are updating every quarter.

General FOGO Acceptance Rules for AS 4736 Packaging

The following principles apply across most councils that have published FOGO materials guidance as of mid-2026:

• AS 4736 or an equivalent certification (EN 13432, TÜV OK Compost Industrial) is the baseline requirement. Councils do not accept self-declared compostable claims — the product must display a recognised logo.
• The certification logo must appear on the packaging item itself, not only on the outer case or supplier's data sheet. This requirement exists so consumers can sort correctly at the bin.
• South Australian and Victorian councils — which have the most mature FOGO infrastructure — explicitly accept both AS 4736 and AS 5810 certified packaging in their programmes.
• A number of NSW councils, including City of Sydney, Inner West Council, Woollahra, and Bayside, now accept certified compostable food packaging in FOGO bins as part of 2024–2025 programme expansions. This list is growing rapidly; always verify with the specific council rather than assuming acceptance based on a neighbouring LGA's policy.
• Regional councils with limited access to industrial composting infrastructure often advise residents to use general waste for packaging — even certified AS 4736 products — because there is no nearby facility capable of processing it at the correct temperature.

What Happens When AS 4736 Packaging Goes to Landfill

This is a question every sustainability manager should be prepared to answer honestly. If certified compostable packaging ends up in landfill rather than reaching a composting facility, it will not biodegrade meaningfully. Landfills are anaerobic — oxygen-deprived — environments. The biodegradation process that AS 4736 tests requires oxygen, moisture, microbial activity, and temperatures of 58°C — none of which a sealed landfill cell provides. Certified compostable packaging in landfill essentially behaves like conventional plastic: slow to degrade and persistent for decades.

This is why certification alone is never the complete solution. The packaging must reach the composting infrastructure it was engineered for. For hospitality businesses, this requires a clearly labelled, operationally maintained bin system — compostable, general waste, and recyclable streams separated at source — and a waste service provider that genuinely processes compostable material rather than co-mingling it with general waste at the depot. Certification without infrastructure is a sustainability claim without a delivery mechanism.

AS 4736 and Australia's State-by-State Plastic Bans

Every Australian state and territory has now enacted single-use plastics legislation, and AS 4736 certified packaging is directly relevant to compliance in two ways: as a replacement for banned plastic items, and as a format that qualifies under the Australian Packaging Covenant Organisation's 2025 targets for 100% of packaging to be reusable, recyclable, or compostable. The key legislative milestones are:

• South Australia: Phase 1 from 1 March 2021 — the first Australian state to ban single-use plastic cutlery, straws, stirrers, plates, and expanded polystyrene food containers.
• Australian Capital Territory: From 1 April 2021 — similar category scope to the SA ban.
• Queensland: Phase 1 from 1 September 2021; Phase 2 from 1 September 2023 — extended scope including polystyrene cups and takeaway containers.
• Western Australia: From 1 October 2022.
• New South Wales: Phase 1 from 1 November 2022 (lightweight plastic bags, plastic straws, cutlery, plates, polystyrene food containers, stirrers); Phase 2 from 1 November 2025 (plastic-lined paper cups, produce bags).
• Victoria: From 1 February 2023 — broad ban covering single-use plastic cutlery, plates, straws, stirrers, and polystyrene food containers.
• Tasmania: From 1 November 2023.
• Northern Territory: Staged single-use plastics ban in effect with implementation phases across categories.

AS 4736 certified alternatives — including takeaway containers made from bagasse and certified cups, cutlery, and plates produced from PLA, CPLA, bamboo, and kraft paper — directly replace the banned categories across all jurisdictions. Switching to certified compostable packaging also positions a business for compliance with APCO's 2025 targets, which require 100% of packaging sold in Australia to be reusable, recyclable, or compostable by end of 2025. Self-declared biodegradable products do not count toward these targets — only certified compostable and certified recyclable products qualify.

Material-by-Material Guide: AS 4736 Certification by Packaging Type

Not all compostable materials are equal in their heat tolerance, liquid resistance, or suitability for specific foodservice applications. Choosing the wrong certified material for a high-temperature or high-moisture application creates operational problems that no certification can solve. This table summarises key performance specifications for the materials most commonly certified to AS 4736:

Material	Max. Temperature Rating	Liquid / Grease Resistance	Industrial Composting Time	Typical Products
Bagasse (sugarcane pulp)	Up to 220°C (oven-safe)	High — naturally grease and liquid resistant	60–90 days	Plates, bowls, clamshell containers, trays, portion cups
PLA (Polylactic Acid)	Up to 60°C (cold and cool liquids only)	Moderate — suitable for cold applications	90–180 days	Cold drink cups, deli containers, clear salad bowls, cold lids
CPLA (Crystallised PLA)	Up to 90°C	Moderate	90–180 days	Hot cup lids, cutlery (knives, forks, spoons)
Kraft paper (uncoated)	Dry use only	Low — not water or grease resistant	30–60 days	Carry bags, napkins, wrapping paper, sandwich wrap
Kraft paper (PLA-lined)	Up to 80°C	High — PLA lining provides liquid barrier	90–180 days (dependent on liner weight)	Coffee cups, soup containers, noodle boxes, hot drink cups
Bamboo fibre (moulded)	Up to 200°C	Moderate — some natural grease resistance	90–180 days	Plates, bowls, cups, cutlery
Wooden (birch or pine)	Dry use only	Low	30–90 days	Cutlery, stirrers, skewers, tasting spoons

For high-volume food service, bagasse is the practical workhorse of the AS 4736 certified range. Its oven-safe heat tolerance, structural rigidity under wet loads, and natural grease resistance make it the safest choice for hot meals, soups, rice dishes, and high-turnover event catering. For beverage service, kraft-PLA lined compostable cups paired with CPLA lids handle hot liquids reliably and are the format most widely accepted by FOGO councils in their certified packaging lists.

Wholesale Cost of AS 4736 Certified Packaging in 2026

The most persistent myth about certified compostable packaging is that it is prohibitively expensive. At wholesale volumes in 2026, the reality is that pricing for certified products has converged significantly with conventional plastic equivalents — particularly for buyers ordering consistently above 500-unit thresholds. Here is a realistic wholesale price guide for common certified categories:

Product Category	Wholesale Price Range (per unit)	Typical Minimum Order	AS 4736 Certification Available
8oz single-wall coffee cup	$0.07–$0.14	500–1,000 units	Yes (kraft/PLA lined)
12oz single-wall coffee cup	$0.09–$0.17	500–1,000 units	Yes (kraft/PLA lined)
500ml rectangular container	$0.18–$0.40	200–500 units	Yes (bagasse)
1,000ml clamshell container	$0.28–$0.60	200–500 units	Yes (bagasse)
Cutlery piece (fork, knife, or spoon)	$0.03–$0.10	1,000 units	Yes (CPLA, wooden, bamboo)
9-inch round plate	$0.14–$0.30	250–500 units	Yes (bagasse)
Paper straw	$0.02–$0.06	500–1,000 units	Yes (kraft paper)

The total cost-of-ownership calculation for certified compostable packaging should factor in waste disposal savings alongside unit cost. Businesses that correctly route certified compostable packaging into FOGO or commercial compost streams typically see their general waste volumes fall materially — and many waste providers charge less per service lift for compostable or organic streams than for general waste. Depending on your council's waste pricing and lift frequency, the disposal saving can partially offset the packaging cost premium, particularly for high-volume operators producing significant food waste alongside packaging waste.

For food businesses setting up a new venue or refitting an existing kitchen, building the waste station infrastructure into the fit-out from day one makes correct sorting operationally sustainable rather than a burden. Hospitality venue electrical and fit-out work — done by licensed tradespeople like APX Trade Group, licensed electricians in Sydney — is an ideal time to plan bin placement, ventilation for compostable waste, and the physical signage that makes staff sorting reliable.

What's Changing in 2026-2027: AS 4736 in a New Regulatory Era

Three significant shifts are reshaping how AS 4736 certification is understood, enforced, and specified across the next 18 months. Packaging buyers who understand these changes now will be better positioned than those who need to react to them mid-contract.

1. Standards Australia Review of AS 4736-2006

AS 4736-2006 has not been substantially updated since its publication. Standards Australia has indicated intent to align the standard more closely with the revised EN 13432 framework currently in development through the European CEN process. The anticipated update is expected to introduce more specific requirements around fluorinated coatings (PFAS) in certified compostable packaging, potentially tighten the 90% biodegradation threshold for certain polymer classes, and create clearer guidance on mixed-material product certification. Buyers sourcing long-term supply agreements now should confirm with their supplier that they are monitoring the review and can demonstrate forward certification compatibility.

2. PFAS Coatings Under Active Scrutiny

Per- and polyfluoroalkyl substances — PFAS — have been used in some grease-resistant coatings applied to compostable food packaging, particularly burger boxes and clamshell containers requiring high grease resistance. The European Union restricted PFAS coatings in food packaging from January 2023. Australia's industrial chemicals regulator has PFAS-containing products under active review, and a growing number of Australian commercial composting facilities have begun excluding packaging containing PFAS from their accepted materials lists — regardless of AS 4736 certification status. When sourcing grease-resistant certified packaging, ask your supplier specifically whether the grease barrier is PFAS-free. Any reputable certified supplier should be able to confirm this without hesitation.

3. FOGO Infrastructure Expanding Rapidly

The NSW Government has committed to FOGO rollout across all 128 NSW councils by 2030, with significant acceleration underway in 2025–2026. Victoria mandated FOGO collection for large metropolitan councils from 1 July 2025. This infrastructure expansion directly increases the realised value of AS 4736 certified packaging — because for every new council that activates FOGO, there is a new composting endpoint available for certified packaging to actually reach. The business case for certified compostable packaging strengthens every quarter as this infrastructure scales.

For food businesses wanting to communicate their certified packaging commitment to customers — through menus, social channels, or their website — a credible digital presence is part of that story. Platforms like weauto, which builds professional websites for Australian businesses from $99, allow small hospitality operators to build a public-facing sustainability page without a large digital investment.

The medium-term outlook for AS 4736 certification is clear: it will become more important, not less, as FOGO infrastructure expands, state plastic bans tighten their scope, and corporate ESG reporting frameworks increasingly require verified claims rather than self-declared environmental commitments. Buyers who have built supplier relationships with proper certification documentation on file will be significantly ahead of competitors who need to scramble when the next regulatory threshold arrives.

Frequently Asked Questions

What is AS 4736 certification in simple terms?

AS 4736 is the Australian Standard that certifies packaging can break down completely — chemically, physically, and without leaving toxic residue — within 180 days in an industrial composting facility operating at 58°C. It requires independent laboratory testing against five specific criteria and must be verified by an accredited third-party body such as the Australasian Bioplastics Association or TÜV Austria. Products that pass all five tests can legally be marketed as certified compostable in Australia, which is a materially different status from simply labelling packaging as biodegradable.

Is AS 4736 the same as EN 13432?

They are not identical but are technically equivalent in scope and threshold requirements. AS 4736 is the Australian standard; EN 13432 is the European standard covering the same industrial composting criteria. Both require the same core tests — biodegradation rate, disintegration, ecotoxicity, and regulated substance limits — with largely the same numerical thresholds. Most Australian councils and composting facilities accept EN 13432 certified products (including those bearing the TÜV Austria OK Compost Industrial logo) as equivalent to AS 4736 certified products.

What is the difference between AS 4736 and AS 5810?

AS 4736 covers industrial composting — products are tested at 58°C, reflecting the conditions of a commercial compost facility. AS 5810 covers home composting — products are tested at ambient temperatures below 30°C, reflecting a backyard compost bin. AS 5810 is in many ways a more demanding standard because achieving biodegradation at low temperatures is chemically harder. PLA-based packaging typically passes AS 4736 but fails AS 5810 because PLA requires sustained high heat to break down — making AS 5810 relevant mainly for natural fibre-based and specific biopolymer formulations.

Can compostable packaging certified to AS 4736 go in FOGO bins?

In most councils that operate FOGO programmes, yes — but you must verify with your specific local council before advising customers or staff to sort this way. Most councils require that packaging display a visible certification logo, and many publish updated accepted materials lists on their websites. Some regional councils with limited composting infrastructure ask residents to place all packaging in general waste regardless of certification status, because there is no local industrial composting facility to process it at the required temperature.

Does "compostable" printed on packaging mean it is AS 4736 certified?

No. The word compostable is a marketing claim that any manufacturer can print on packaging without independent verification or testing. Only the presence of a recognised certification logo — ABA Certified Compostable, TÜV Austria OK Compost Industrial, DIN CERTCO, or BPI — confirms that the product has been independently tested against AS 4736 or a recognised equivalent standard. If you see compostable without a logo, request the supplier's Certificate of Conformity with a specific product code before placing a bulk order.

Is AS 4736 certified packaging significantly more expensive than plastic?

At wholesale volumes, the price premium is typically 10–40% above conventional plastic equivalents depending on the product category. For everyday items like coffee cups, the difference is often less than $0.05 per unit at volume pricing, and the gap narrows further when waste disposal savings from correctly routed compostable waste streams are factored in. Paper straws and wooden cutlery — two of the most commonly needed certified compostable items — are now cost-competitive with plastic equivalents at wholesale quantities above 1,000 units.

What are my legal obligations if I buy packaging labelled AS 4736 that turns out to be uncertified?

Under Australian Consumer Law, making or passing on a false or misleading environmental claim — including the representation that packaging is compostable when it has not been independently certified — can expose a business to ACCC scrutiny, even if the original claim came from a supplier. Businesses should request and retain Certificates of Conformity for any certified compostable packaging they purchase, and should not repeat a supplier's compostable claim to customers unless they have verified the certification documentation. If a supplier cannot produce a current certificate for a specific product code, treat the claim as unverified.

Where can I test certified compostable packaging before ordering in bulk?

Reputable wholesale suppliers offer sample orders or curated sample packs so buyers can test real-world performance — heat tolerance, structural integrity under wet food loads, liquid resistance — before committing to a full case order. Testing is the only way to confirm that a product performs as specified in your specific service context, because temperature tolerance ratings and grease resistance figures are measured under standardised lab conditions that may not precisely replicate your kitchen environment.
