What Is Oxo-Degradable Packaging — and Why Is It Still on Shelves?
Oxo-degradable packaging is conventional plastic — typically low-density polyethylene (LDPE) or high-density polyethylene (HDPE) — embedded with a pro-oxidant additive that accelerates fragmentation when the material is exposed to UV light, heat, or mechanical stress. The additive, usually a metal salt compound such as cobalt stearate, manganese, or iron, catalyses oxidative degradation of the polymer backbone.
The key word is fragmentation, not decomposition. Oxo-degradable packaging does not biodegrade. It breaks into progressively smaller pieces of plastic — ending as microplastics and, eventually, nanoplastics — which persist in soil, waterways, and marine environments for decades. The plastic carbon chain remains intact throughout this process. Nothing is converted to organic matter, and nothing enriches the soil.
So why is it still sold? Largely because pro-oxidant additive manufacturers aggressively marketed these products throughout the 2000s and 2010s as “biodegradable” or “eco-friendly” alternatives to conventional plastic. Trade names like d2w (Symphony Environmental Technologies) and EPI (EPI Environmental Technologies) became common on Australian supermarket shelves and restaurant supply catalogues. Businesses that genuinely wanted to reduce their environmental footprint purchased these products in good faith — and were misled.
The science has since caught up with the marketing. A 2019 report commissioned by the European Commission concluded that oxo-degradable plastics do not offer any proven environmental benefit over conventional plastics and pose a significant risk of increased microplastic contamination. The EU responded by banning all oxo-degradable plastic packaging under the Single-Use Plastics Directive (SUPD) from 3 July 2021. In Australia, the regulatory trajectory is following the same direction — and the case for oxo-degradable packaging has effectively collapsed.
What Is Compostable Packaging? Definitions, Standards, and Certifications
Compostable packaging is made from organic, renewable materials — typically sugarcane pulp (bagasse), polylactic acid (PLA) derived from cornstarch, CPLA (crystallised PLA), bamboo fibre, or unbleached kraft paper — that are designed to break down completely into carbon dioxide, water, inorganic compounds, and biomass under composting conditions. The end product is compost: a substance that enriches soil rather than contaminating it.
The critical distinction from oxo-degradable is biological: certified compostable packaging undergoes genuine microbial decomposition. Bacteria and fungi metabolise the material at a cellular level. No plastic fragment remains. This is not a marketing claim — it is a measurable outcome verified through independent laboratory testing against Australian Standards.
In Australia, the term “compostable” carries legal weight and is regulated through two primary standards, each corresponding to a different disposal pathway.
Industrial Compostable: AS 4736
AS 4736:2006 (Biodegradable plastics — Biodegradable plastics suitable for composting and other microbial treatment) is the Australian standard for industrial or commercial composting. To achieve AS 4736 certification, a packaging product must meet all of the following criteria:
- Disintegrate by more than 90% within 12 weeks in a controlled composting environment at 58°C (±2°C)
- Biodegrade by at least 90% (measured as CO² evolution) within 180 days
- Pass ecotoxicity testing — the resulting compost must demonstrate no inhibition of plant growth relative to a control
- Contain no more than 50% dry weight of volatile solids after the test period
- Meet regulated heavy metal concentration limits (lead, cadmium, mercury, chromium, copper, nickel, zinc, molybdenum, selenium, arsenic, cobalt, fluoride)
AS 4736 certification in Australia is administered by the Australasian Bioplastics Association (ABA), which licenses the internationally recognised seedling logo. Products certified to AS 4736 are accepted at commercial composting facilities and, where council guidelines permit, in FOGO (Food Organics Garden Organics) collection bins. Every product stocked in our full range of 700+ eco products that carries a compostable claim is certified to AS 4736 or AS 5810.
Home Compostable: AS 5810
AS 5810:2010 (Biodegradable plastics — Biodegradable plastics suitable for home composting) is a more demanding standard, requiring breakdown under ambient, uncontrolled conditions that replicate a backyard compost heap. Requirements include:
- Disintegration by more than 90% within 26 weeks at ambient temperatures (typically 20–30°C)
- Biodegradation of at least 90% within 12 months
- The same ecotoxicity and heavy metal requirements as AS 4736
AS 5810 certification is rarer and more expensive to obtain, which is why fewer products carry it. It is the gold standard for consumers with backyard compost systems and is accepted by most FOGO programs that process material through slower, lower-temperature in-vessel or windrow composting. Critically, every product that meets AS 5810 also meets AS 4736 — but not vice versa. Our article on AS 4736 vs AS 5810 certification differences breaks down the practical implications in detail.
How to Verify a Compostable Claim in Australia
Australian Consumer Law requires that environmental claims be truthful, accurate, and not misleading. The ACCC reinforced this with updated guidance in 2023, making clear that vague sustainability terms breach consumer protection law. The proposed AS 4631 labelling standard is designed to bring consistency to compostable labelling in Australia — requiring products to display the relevant standard number, the certification body’s logo, and clear disposal instructions on the packaging itself.
If a product claims to be “compostable” without displaying an AS 4736 or AS 5810 certification number and an ABA seedling logo, treat it with caution. The ABA certification database is publicly searchable — you can verify any product’s status before placing a wholesale order. Our guide to verifying AS 4736 compostable certification walks through the process step by step.
Compostable vs Oxo-Degradable: The Full Side-by-Side Comparison
The table below synthesises the core technical, regulatory, and practical differences between compostable packaging and oxo-degradable packaging — alongside conventional plastic and recyclable plastic for complete context. This framework is designed to help packaging buyers, sustainability officers, and procurement managers make fully informed decisions.
| Feature | Certified Compostable | Oxo-Degradable | Conventional Plastic | Recyclable Plastic |
|---|---|---|---|---|
| Base material | Bagasse, PLA/CPLA, bamboo, kraft paper | LDPE or HDPE + pro-oxidant metal salt additive | Petrochemical polymers (virgin) | Petrochemical polymers (PET, HDPE, PP) |
| End product after breakdown | CO², water, compost (biomass) | Microplastic and nanoplastic fragments | Persists 400–1,000 years | Reprocessed into new plastic (if collected and clean) |
| Australian certification standard | AS 4736:2006 (industrial) / AS 5810:2010 (home) | None — no Australian standard exists | n/a | APCO / Australasian Recycling Label (ARL) scheme |
| Accepted in FOGO bins | Yes — if AS 4736 or AS 5810 certified and council-approved | No — excluded by all Australian councils | No | No |
| Recyclable in kerbside recycling | No (contaminates plastic recycling stream) | No (contaminates plastic recycling stream) | Plastic types 1, 2, 5 in most councils | Yes (correct type and clean) |
| Creates microplastics | No | Yes — by design, through fragmentation | Yes — slowly, under UV and mechanical stress | Potentially during mechanical reprocessing |
| Biodegrades in landfill | Unlikely — anaerobic landfill conditions inhibit composting | No — fragments persist indefinitely | No | No |
| Typical wholesale cost per unit | $0.05–$0.50+ depending on product type | $0.02–$0.08 (bags/film; now largely banned) | $0.01–$0.08 | $0.02–$0.15 |
| Banned in EU | No (encouraged in circular economy policy) | Yes — from 3 July 2021 under SUPD | Select single-use items banned | No |
| Status in Australian state bans | Encouraged — accepted as compliant alternative | Excluded — not a compliant alternative in any state | Many single-use items banned by state | Not restricted |
| Decomposition timeline | 6–12 weeks (industrial); 3–6 months (home) | Fragments within months; plastic persists indefinitely | 400–1,000 years | Indefinite if not recycled |
| Meets APCO 2025 national targets | Yes — qualifies as “compostable” | No — qualifies under none of the three categories | No (unless recyclable) | Yes — qualifies as “recyclable” |
The table makes one conclusion unavoidable: oxo-degradable packaging offers none of the genuine environmental benefits of certified compostable packaging, while introducing the additional harm of deliberate microplastic generation. It is the worst of both worlds — more expensive than conventional plastic, and more damaging than its marketing suggests.
The Microplastic Problem: What Oxo-Degradable Packaging Actually Does in the Environment
To understand why oxo-degradable packaging is environmentally harmful, you need to understand what the pro-oxidant additive actually does at the molecular level. When conventional plastic film is embedded with a metal salt catalyst — cobalt stearate is common, as are proprietary blends used in d2w and EPI formulations — the additive accelerates the oxidation of the polymer backbone.
When the packaging is exposed to UV radiation, elevated temperature, or mechanical abrasion, the long polymer chains begin to break apart. The plastic becomes brittle, cracks, and fragments into smaller and smaller pieces. This happens relatively quickly in outdoor environments — within months to a few years, depending on conditions. This visible fragmentation is what manufacturers showcased as evidence of “degradation.”
It is not degradation. The fragments are still plastic. They carry the same petrochemical carbon chains. They are simply too small to see. A 2018 study published in Science of the Total Environment tested oxo-degradable plastic bags under three conditions — marine water, freshwater, and burial in soil — over an 18-month period. The bags did not biodegrade under any condition tested. Some samples retained significant tensile strength after the test period, suggesting fragmentation had not even fully occurred. No study has ever demonstrated genuine biodegradation of an oxo-degradable plastic under any real-world environmental condition.
The pro-oxidant additives themselves introduce a secondary concern. Metal catalysts including cobalt can leach into soil and water as the plastic fragments. The very same ecotoxicity criteria that certified compostable packaging must pass — demonstrating no harm to plant growth and no heavy metal contamination above regulated limits — do not apply to oxo-degradable products at all. There is no testing regime, no certification standard, and no ongoing monitoring framework for oxo-degradable packaging in Australia.
There is also a recycling contamination problem that is largely invisible to consumers. Oxo-degradable packaging has the same near-infrared (NIR) spectral signature as conventional LDPE or HDPE. Sorting equipment at Australian Materials Recovery Facilities (MRFs) cannot differentiate oxo-degradable from standard film. If oxo-degradable packaging enters the kerbside recycling stream, it is sorted into the plastic fraction — and then contaminates it. The pro-oxidant additive accelerates degradation in recycled plastic end-products, reducing their mechanical integrity and useful life. Major Australian plastic recyclers and the APCO have specifically identified oxo-degradable materials as incompatible with the recycling stream.
Australian and Global Regulations: Where Oxo-Degradable Currently Stands
The EU Ban — the Global Benchmark
The European Union’s Single-Use Plastics Directive (SUPD), which came into force on 3 July 2021, explicitly prohibited oxo-degradable plastic products — defined as any plastic product made from plastic that includes additives which cause the plastic to fragment into micro- or nanoplastics, or to undergo partial biological decomposition. This is the most comprehensive and legally precise ban on oxo-degradable packaging anywhere in the world.
The EU ban is based on the precautionary principle and the weight of scientific evidence — including the European Commission’s own 2019 technical report. It sets a clear international signal: oxo-degradable is not an acceptable sustainability solution, and its continued manufacture and use in the EU is prohibited. For Australian businesses importing packaging from European suppliers, this means the EU supply chain has already been cleansed of oxo-degradable products.
Australian State and Territory Legislation
Australia does not yet have a single national federal ban specifically targeting oxo-degradable packaging. However, the cumulative effect of state-level single-use plastics bans is to make oxo-degradable non-compliant as a substitute for banned items in every jurisdiction:
- New South Wales: The Plastic Reduction and Circular Economy Act 2021 banned lightweight plastic bags from 1 November 2022, with expanded items including produce bags phased out from 1 November 2025. The NSW definition of “plastic” captures oxo-degradable materials. Businesses cannot use oxo-degradable bags as a compliant replacement for banned conventional bags.
- Queensland: Queensland’s staged single-use plastics ban (commencing 2021 and extending in 2023) explicitly defined “acceptable alternatives” — and oxo-degradable packaging was not among them. Supplying oxo-degradable bags as an eco-friendly substitute for banned items constitutes non-compliance.
- Victoria: Victoria’s single-use plastics legislation, phased in from 2023, does not recognise oxo-degradable materials as compliant alternatives. Lightweight bags, expanded polystyrene food service items, and certain plastic produce packaging are banned, with no oxo-degradable carve-out.
- South Australia: SA has been the national leader in plastic bag bans since its Environment Protection (Plastic Shopping Bags) Act 2008. Oxo-degradable bags have never been considered acceptable substitutes under SA law — the longest-standing position of any Australian jurisdiction.
- Western Australia: WA’s Environmental Protection (Plastic Bags) Act 2019 banned lightweight plastic checkout bags, and the regulatory framework does not accept oxo-degradable alternatives. Further items are being phased out under WA’s expanding single-use plastics policy.
- ACT, Tasmania, Northern Territory: All have enacted or are progressing single-use plastics legislation consistent with the national direction, with oxo-degradable materials uniformly excluded from acceptable alternative classifications.
The practical implication: if your business is using oxo-degradable bags as a lower-cost “eco” substitute for conventional plastic bags in any Australian state, you are likely operating in breach of state legislation. The regulatory risk is real, and the supposed cost savings are marginal.
APCO National Packaging Targets 2025
The Australian Packaging Covenant Organisation (APCO) established a national target that 100% of Australia’s packaging be reusable, recyclable, or compostable by 2025. Oxo-degradable packaging does not qualify under any of these three categories. It is not reusable by design. It is not recyclable — it contaminates plastic streams. And it is not compostable — no oxo-degradable product has ever achieved Australian compostable certification under AS 4736 or AS 5810, and none could, because it does not biodegrade.
For businesses with APCO reporting obligations — which include most large food retailers, food service operators, and major brand owners — continued use of oxo-degradable packaging represents a gap in compliance reporting. For businesses preparing sustainability disclosures under frameworks like GRI or ISSB standards, oxo-degradable packaging is an exposure, not an asset.
What This Means for Your Food Business in 2026
If you operate a café, restaurant, food truck, catering company, or event venue, here is the practical translation of everything above.
If You Are Currently Using Oxo-Degradable Packaging
Stop. Not primarily because of regulatory risk — though that is real and growing. Stop because the core premise of oxo-degradable packaging is false: it does not provide an environmental benefit over conventional plastic. You are paying a higher per-unit cost than conventional plastic for a product that creates microplastic pollution, cannot go into recycling, cannot go into FOGO bins, and will not survive scrutiny from customers, councils, or auditors.
The switch to certified compostable packaging requires one key action: ensuring every product you purchase carries an AS 4736 or AS 5810 certification number visible on the packaging. Check the ABA database to verify claims before committing to a wholesale order. The transition is not expensive — compostable cups, containers, cutlery, and bags are widely available at competitive wholesale pricing, and volume pricing makes the gap with conventional plastic smaller than most buyers expect.
FOGO Programs and Council Acceptance
One of the most significant practical benefits of certified compostable packaging — entirely unavailable to oxo-degradable — is compatibility with FOGO council collection programs. As of 2026, FOGO rollout has expanded substantially across Australia. The NSW Environment Protection Authority has mandated councils to provide FOGO collection for all households by 2030, with many councils already running full programs. Similar expansions are underway in Queensland, Victoria, and South Australia.
Councils including the City of Sydney, Inner West Council, Randwick City Council, Waverley Council, Georges River Council, and a growing number of regional councils now accept AS 4736 certified compostable packaging in FOGO bins — either through residential collection or commercial food waste services. This creates a genuine closed loop: certified compostable containers and cups purchased from a wholesale supplier can end their life as compost rather than landfill.
The critical caveat: acceptance varies significantly between councils. Some accept only food scraps in FOGO bins, not packaging, pending upgrades to their composting processor. Always verify your specific council’s guidelines before communicating disposal options to your customers. Oxo-degradable packaging is not accepted in any FOGO program in Australia — there are no exceptions to this rule.
Cost Analysis: What You Actually Pay Across Product Categories
The cost argument for oxo-degradable packaging has always rested on the claim that it is “almost as cheap as conventional plastic.” Even setting aside the regulatory and environmental problems, this argument has a practical flaw: oxo-degradable packaging is almost exclusively available as bags and film. It is not available as takeaway containers, coffee cups, plates, bowls, or cutlery. For the vast majority of food service packaging categories, the choice was always between conventional plastic and compostable — oxo-degradable was never on the table.
For the bag and film category where oxo-degradable does compete, here is a realistic wholesale cost comparison at typical food service volumes:
| Product Category | Conventional Plastic (per unit) | Oxo-Degradable (per unit) | Certified Compostable (per unit) |
|---|---|---|---|
| Checkout / carry bags (medium) | $0.01–0.03 | $0.03–0.07 (now largely banned in most states) | $0.06–0.18 (kraft paper or certified compostable film) |
| Produce / mushroom bags | $0.01–0.02 | $0.02–0.05 (banned in NSW from Nov 2025) | $0.04–0.10 |
| Takeaway containers 500–750ml | $0.08–0.15 | Not available in compostable format | $0.20–0.45 (bagasse or PLA) |
| Coffee cups 8oz | $0.06–0.10 | Not available | $0.10–0.18 (kraft paper, PLA-lined) |
| Cutlery sets (fork, knife, spoon) | $0.03–0.07 | Not available | $0.06–0.14 (CPLA or bamboo/wood) |
| Plates / bowls 9-inch (bagasse) | $0.05–0.12 | Not available | $0.12–0.35 |
The cost premium for certified compostable packaging over conventional plastic ranges from approximately 50% to 200% depending on the product. This is a genuine consideration for high-volume operators. However, there are three factors that offset this in whole or in part:
- Waste disposal cost reduction: A business that segregates certified compostable packaging into a commercial organics waste stream typically pays less per kilogram for organics disposal than for general waste disposal. At scale, this reduces total waste costs.
- Regulatory compliance certainty: Using certified compostable packaging eliminates the legal and reputational risk associated with using non-compliant oxo-degradable or banned conventional plastic alternatives.
- Customer perception and pricing power: Research consistently demonstrates that Australian consumers — particularly the 25–45 demographic that dominates café and restaurant spending — are willing to pay more, and return more frequently, to businesses they perceive as environmentally responsible. Sustainable packaging is a documented driver of repeat purchase in food service.
How to Spot Greenwashing: Red Flags on Eco Packaging Claims
Oxo-degradable packaging is the packaging industry’s most clear-cut case of greenwashing. But it is not the only one. Understanding the language of misleading eco claims protects your business from stocking non-compliant products — and from reputational damage when your customers figure it out.
Here are the specific red flags to look for when evaluating any packaging supplier’s eco claims:
- “Degrades in the environment” — This phrase describes oxo-degradable fragmentation into microplastics, not biodegradation. Any supplier using this language without a certification number should be pressed for verification.
- “Will break down in landfill” — Certified compostable packaging does not reliably break down in landfill either (anaerobic conditions inhibit the aerobic microorganisms required for composting). This claim is misleading for any packaging type and should prompt immediate scepticism.
- “Made with plant-based materials” — PLA and bagasse are indeed plant-derived, but so is conventional paper. The claim tells you nothing about end-of-life performance. Look for the certification standard number, not the feedstock description.
- “Eco-friendly” or “green” without certification — These terms have no regulated meaning in Australia. The ACCC updated its guidance on environmental claims in 2023 and has specifically flagged vague, unsubstantiated eco language as a consumer law concern.
- No certification logo or number visible on pack — Any legitimate compostable packaging will display the ABA seedling logo with a traceable certification number. Its absence is not a minor oversight — it means the product has not been independently tested.
- “Biodegradable plastic bag” without citing a standard — This description has historically been applied to oxo-degradable bags and has been found misleading by courts and regulators in multiple jurisdictions. Without an AS 4736 or AS 5810 number, the term is unverifiable.
When evaluating a new packaging supplier, ask one direct question: “Can you provide the ABA certification number for this product?” If the answer is not an immediate yes with a number, request the certification documentation before ordering. This single check eliminates most greenwashing risk in your supply chain.
The 2026–2027 Outlook: What Packaging Buyers Should Prepare For
The regulatory and commercial environment for packaging in Australia is tightening, and the direction is consistent: certified compostable, reusable, and recyclable are the only defensible packaging pathways. Here is what forward-thinking buyers should be positioning for over the next 12–24 months.
- FOGO coverage expansion: The NSW mandate requiring all councils to provide FOGO by 2030 is driving capital investment in composting infrastructure statewide. As processing capacity increases, more councils will expand their FOGO acceptance criteria to include certified compostable packaging — not just food scraps. Businesses already using AS 4736 certified packaging will be positioned to immediately benefit from expanded diversion options and the ability to market genuine closed-loop outcomes to customers.
- AS 4631 labelling standard: The finalisation and mandatory adoption of AS 4631 compostable labelling requirements will raise the bar for what can legally appear on packaging as “compostable.” Businesses holding non-certified stock when this standard takes effect face potential compliance and reputational exposure. Getting your supply chain certified now avoids this transition risk.
- Federal product stewardship expansion: The Recycling and Waste Reduction Act 2020 is progressively extending mandatory product stewardship obligations to new packaging categories. This will increase compliance scrutiny on all environmental claims, including any remaining oxo-degradable products in the market, and accelerate the case for certified compostable alternatives.
- Consumer and procurement pressure: Australian consumers increasingly verify eco claims before purchase, and government and corporate procurement policies are requiring certified sustainable packaging in tenders and supply chain due diligence. A business that has not completed the transition to certified packaging is increasingly at risk of being excluded from contracts and councils where sustainability compliance is a condition of supply.

Frequently Asked Questions
Is oxo-degradable packaging banned in Australia?
There is no single national federal ban specifically targeting oxo-degradable packaging in Australia as of 2026. However, the state-level single-use plastics bans in NSW, QLD, VIC, SA, WA, the ACT, and Tasmania define “plastic” in ways that capture oxo-degradable materials, and all explicitly exclude oxo-degradable from acceptable eco-friendly alternatives. In most states, using oxo-degradable bags as a substitute for banned lightweight plastic bags is non-compliant. The EU banned all oxo-degradable plastic packaging from July 2021, setting a precedent that Australian regulators are expected to follow.
What is the difference between oxo-degradable and biodegradable packaging?
Biodegradable is a broad term covering any material that microorganisms can break down. Certified compostable packaging is biodegradable — it is fully metabolised by bacteria and fungi in composting conditions, converting to CO², water, and compost. Oxo-degradable packaging fragments through chemical oxidation rather than biological activity — no microorganism metabolises the plastic fragments. The term “oxo-biodegradable,” used in some manufacturer marketing, has been characterised as misleading by the European Commission and independent scientific bodies. The two are not interchangeable.
Can compostable packaging go in a FOGO bin?
Certified compostable packaging carrying AS 4736 or AS 5810 certification is accepted in FOGO bins by a growing number of Australian councils — including many in NSW, VIC, and QLD. However, acceptance varies by council depending on the composting infrastructure available. Always check your council’s specific guidelines before advising customers on disposal. Oxo-degradable packaging is not accepted in any Australian FOGO program under any circumstances — there are no exceptions to this rule across any council in any state.
What certifications should I look for on compostable packaging in Australia?
Look for the ABA (Australasian Bioplastics Association) seedling logo with a certification number, which confirms testing against AS 4736:2006 (industrial composting) or AS 5810:2010 (home composting). TÜV Austria “OK compost” (industrial or home) certification is also internationally recognised and accepted by Australian composting facilities. Always verify the certification number against the ABA’s public database before placing a wholesale order — a logo on packaging without a verifiable certification number may indicate an uncertified product.
Is oxo-degradable packaging recyclable in kerbside recycling?
No. Oxo-degradable packaging should never be placed in kerbside recycling bins. It has the same near-infrared spectral signature as conventional LDPE or HDPE, making it undetectable by sorting equipment at Australian Materials Recovery Facilities. If it enters the recycling stream, it contaminates the plastic fraction — the pro-oxidant additive accelerates degradation in recycled plastic products, reducing their quality and lifespan. Major Australian plastic recyclers have called for oxo-degradable materials to be explicitly excluded from all recycling streams.
What does AS 4736 certified mean for a food service packaging product?
AS 4736 certification means the packaging has been independently tested and confirmed to: (1) disintegrate by more than 90% within 12 weeks in a commercial composting environment at 58°C; (2) biodegrade by at least 90% within 180 days; and (3) produce compost that passes ecotoxicity testing — meaning it supports plant growth and contains no prohibited substances above regulated heavy metal limits. Certification is not self-declared. It requires third-party laboratory testing through an ABA-accredited body and periodic re-certification to maintain the licence to use the seedling logo.
How long does certified compostable packaging take to break down?
In a commercial composting facility operating under AS 4736 conditions (58°C, controlled moisture and aeration), certified packaging typically disintegrates within 6–12 weeks and achieves full biodegradation within 90–180 days. Under home composting conditions (AS 5810), the same process takes 3–6 months at ambient temperatures. Importantly, compostable packaging does not break down reliably in landfill — anaerobic conditions inhibit the aerobic microorganisms required. This is why proper disposal via FOGO bins or commercial composting is essential to realising the environmental benefit.
Why was oxo-degradable packaging sold as eco-friendly if it creates microplastics?
Oxo-degradable additives were developed and commercialised from the 1990s, predating the scientific understanding of microplastic pollution as a systemic environmental problem. Manufacturers relied on visible fragmentation — the plastic breaking apart quickly in the environment — as proof of “degradation.” Peer-reviewed science published from roughly 2015 onwards demonstrated conclusively that fragmentation is not biodegradation, and the 2019 European Commission technical report synthesised this evidence into policy. The EU SUPD ban in 2021 was the definitive regulatory response. Many Australian distributors who carried oxo-degradable products have since transitioned their ranges to certified compostable alternatives.
