Australia Compostable Bags Requirements.
What is the Queensland Plastic Bag Ban
- Since July 2018, Queensland bans all lightweight plastic shopping bags. business.
- “Lightweight” means thin plastic film or bags under the defined thickness rules.
- The ban covers many types of plastic bags — including those labelled “biodegradable” or “compostable.”
Who Must Comply With Queensland Compostable Bag Regulations
Queensland’s plastic bag ban does not only affect retailers at checkout.
In practice, compliance responsibility often applies to:
- Bag manufacturers and overseas exporters
- Importers and brand owners
- Packaging wholesalers and distributors
- Supermarkets and retail chains
- Hospitality groups and food service suppliers
If a non-compliant bag is supplied, liability may fall on the supplier or importer, even if the bag is marketed as “compostable” or “environmentally friendly”.
For B2B buyers, compostable bags are a procurement and compliance issue, not just a packaging choice.
When Compostable Bags Are Allowed in QLD
Compostable plastic shopping bags are allowed — but only if they meet all of these conditions:
- The bag must be wholly made from certified compostable plastic (meet AS 4736 or AS 5810 standard).
- The bag must meet the thickness and reusability requirements (for example enough to carry 10 kg, and last many uses).
- If the bag includes non-compostable plastic parts, those parts must meet the recycled-content requirement.
If all conditions are met, the bag can be legally supplied. If not, it is banned under the Queensland plastic bag ban.
How B2B Buyers Should Select Compostable Bags in Queensland
For bulk buyers, selecting compostable bags in Queensland requires more than checking a certification logo.
Key procurement checks include:
1. Bag purpose
- Shopping bags (highly regulated)
- Produce bags
- Compostable bin liners
- Organics or food waste liners
Each use is treated differently under Queensland law.
2. Certification and performance
- AS 4736 or AS 5810 certification is required
- Bags must also meet thickness, durability, and reuse requirements
- Certification alone does not override the plastic bag ban
3. Material composition
- Bags must be fully compostable, or
- Any non-compostable parts must meet recycled-content rules
4. Documentation
- Certification certificates
- Test reports for thickness and strength
- Clear labelling and disposal instructions
For large orders, buyers should confirm compliance before purchase, not after supply.
Why the Rules Exist
The rules are not just about banning plastic. They aim to:
- Prevent light plastic pollution and litter.
- Encourage reuse or certified compostable options.
- Avoid false or misleading “green” claims that deceive consumers.
If a retailer or supplier offers a bag that fails the rules, they risk fines and legal penalty.
Compliance Risk for Suppliers and Importers
In Queensland, supplying a non-compliant compostable bag can result in:
- Enforcement action and fines
- Product withdrawal
- Contract disputes with retail or government clients
- Reputational damage
Common risk areas include:
- Using “biodegradable” instead of certified compostable materials
- Importing bags certified overseas but not tested to Australian standards
- Supplying shopping bags that fail thickness or reuse tests
Many businesses reduce risk by working with suppliers who can provide compliance-ready specifications and documentation, not just products.
What “Compostable” Means — Standards in Queensland
Two main Australian standards matter:
AS 4736 — for industrial / commercial composting.
AS 5810 — for home composting.
Even with these standards, compostable plastics often need special composting conditions (proper facility, correct temperature and microbes). Ordinary home compost or landfill may not break them down fully.
So don’t assume “compostable” means “will vanish anywhere.”
What Products Are Restricted — Bags, Liners, Packaging
- Single-use lightweight plastic shopping bags remain banned, even if labelled compostable.
- Certified compostable shopping bags (meeting rules above) are allowed.
- Non-bag plastic items (lightweight food packaging, serviceware) may also face restrictions under broader waste laws.
- Compostable bin liners or organics bags — legality depends on state waste scheme, compost facility, and local council acceptance.
What Suppliers and Retailers Must Do to Comply
If you supply or manufacture bags for Queensland market:
- Check bag is fully compostable (no non-compostable plastic mixed).
- Ensure compliance with AS 4736 or AS 5810, and meet thickness / durability / reuse criteria.
- Avoid vague or misleading claims (e.g. just “biodegradable” or “eco-friendly”). Queensland laws penalise misleading claims.
- Provide documentation or certification if asked. Keep proof of compliance.
- For organics / bin liners / compostable packaging: verify final disposal route (industrial composting), not assume household compost or landfill will work.
