FSC, PLA and Compostable Certifications Explained for Australian Businesses
What FSC, PLA, AS 4736 and the seedling logo actually mean on packaging cartons - and the greenwashing red flags Australian trade buyers should check before ordering.
Pick up any carton in your next delivery and count the logos: a tree tick here, a seedling there, "biodegradable" in a green starburst. Some of those marks are backed by an Australian Standard and a public register you can check in two minutes. Others mean nothing at all - and under Australian Consumer Law, repeating a claim you cannot substantiate is a legal risk, not just a branding one.
This guide decodes the certifications that matter on wholesale packaging in Australia - FSC certified paper, PLA and CPLA bioplastics, and the AS 4736 and AS 5810 compostability standards behind the seedling logo - so you can tell certified compostable from wishful thinking before you commit to a pallet.
The short version
- FSC certifies where paper fibre comes from - not whether an item composts. Check the label type (100%, Mix or Recycled) and the FSC-C licence code.
- PLA is a plant-based plastic. It is certified compostable in commercial facilities (AS 4736) - not in a home compost bin, and never in kerbside recycling.
- AS 4736 means commercially compostable; AS 5810 means home compostable. The seedling and ABA home compostable logos verify them - always alongside a licence number.
- "Biodegradable" on its own is a red flag: no standard, no timeframe, no conditions.
- Genuine claims can be verified free in the FSC and ABA public registers. If a supplier cannot point you to one, keep asking questions.
FSC certification - what the tree logo on paper packaging actually means
So what does FSC mean? The Forest Stewardship Council is a non-profit that has run the world's leading forest certification system since 1994, with more than 160 million hectares of forest certified worldwide. On packaging - paper cups, bags, napkins, greaseproof and board - FSC certified paper means the fibre has been tracked from a responsibly managed forest through every manufacturing step under chain-of-custody certification.
Two things FSC does not tell you: whether the item is food safe, and whether it composts. An FSC label answers one question only - where the fibre came from. End-of-life is a separate certification, covered further down.
The three FSC labels - 100%, Mix and Recycled
"FSC certified" is not a single claim; the label variant matters:
- FSC 100% - every input comes from FSC-certified forests.
- FSC Mix - a blend of certified fibre, recycled material and controlled wood. At least 70% must be certified or reclaimed inputs; the controlled-wood remainder is vetted against illegal harvesting and other unacceptable sources, but is not itself certified.
- FSC Recycled - 100% reclaimed fibre, pre- and post-consumer.
Alongside FSC certification in Australia you may also see a second scheme: Responsible Wood, the PEFC-endorsed national system formerly known as the Australian Forestry Standard. Both are recognised by the Australian Government - FSC is simply the mark international buyers know best.
How to verify an FSC claim in two minutes
Every legitimate FSC label carries a licence code in the format FSC-C followed by six digits. That code identifies the certificate holder - usually the manufacturer, since wholesalers reselling finished, labelled goods do not need their own chain-of-custody certificate. To check a claim: find the FSC-C code on the carton or invoice, search it in the FSC public certificate database (free, no login), and confirm the certificate is valid and covers the product type you are buying. A tree logo with no code is not a valid FSC claim.
Bioplastics decoded
PLA and CPLA - the certification buyers get wrong
What does PLA mean? Polylactic acid - a bioplastic made by fermenting plant starch from corn or sugarcane into lactic acid, then polymerising it. It looks and feels like conventional clear plastic, which is exactly why PLA packaging causes so much confusion. The facts that matter when you buy:
- PLA is certified commercially compostable (AS 4736). It is not certified home compostable and will sit unchanged in a backyard bin.
- It never goes in kerbside recycling - clear PLA cups look like PET and contaminate the stream.
- Standard PLA softens from about 40 degrees C: cold drinks only, and keep cartons out of hot vans.
- CPLA (crystallised PLA, used for hot lids and cutlery) is heat-treated to handle roughly 85 degrees C.
- "Compostable" hot cups are paper with a PLA lining instead of polyethylene - a lining that is still, technically, a plastic.
AS 4736 and AS 5810 - Australia's compostability standards
"Compostable" only means something when a standard sits behind it. Australia has two, and compostable certification against each is administered by the Australasian Bioplastics Association (ABA) through independent accredited laboratories.
AS 4736 vs AS 5810 - the practical difference
AS 4736-2006 is the commercial standard. To pass, a plastic must biodegrade at least 90% within 180 days and disintegrate at least 90% into fragments smaller than 2mm within 12 weeks under industrial composting conditions - hot, managed processing a home heap cannot replicate - with no toxic effect on plants or earthworms. That worm test is the detail worth remembering: AS4736 certification is modelled on Europe's EN 13432 but adds an earthworm ecotoxicity requirement, which makes the Australian mark slightly stricter.
AS 5810-2010 is the home compostable certification standard - the same 90% thresholds, but proven at ambient backyard temperatures of 20 to 30 degrees C over longer windows: six months to disintegrate, twelve to biodegrade. It is the harder test. An item certified home compostable will cope with a commercial facility; a commercial-only item will not reliably break down at home.
The seedling logo and ABA licence numbers
What is the seedling logo? It is the on-pack mark of AS 4736 certification - a trademark owned by European Bioplastics and administered in Australia and New Zealand by the ABA. Home compostable products carry a separate ABA home compostable logo. Either way, the logo is only half the claim: every certified product also carries a unique licence number, checkable against the ABA's public list of certified products. A logo without a number is greenwashing until proven otherwise.
Two Victorian wrinkles worth knowing. Kerbside FOGO services accept only certified compostable caddy liners - lime green, seedling logo, licence number on the roll. And the state's single-use plastics ban covers bioplastics too: certified compostable plastic straws, cutlery and plates are just as banned as conventional ones. Wood, bamboo and paper are the compliant route - our guides to plastic alternatives for Australian venues and wooden vs bamboo cutlery cover the swaps.
OK Compost and EN 13432 - the imported marks
Imported lines often carry TUV Austria's OK Compost (EN 13432, industrial) or OK Compost Home marks instead. EN 13432 certification is broadly equivalent to AS 4736 minus the worm test, and OK Compost Home broadly parallels AS 5810. They are genuine third-party marks - but if your customers or council contracts specify the Australian standard, ask the supplier whether AS certification is also held.

The certification cheat sheet
Five marks you will see on wholesale packaging cartons - and the check that proves each one.
| Mark | What it certifies | Who runs it | The two-minute check |
|---|---|---|---|
| FSC 100% / Mix / Recycled | Paper fibre from responsibly managed forests, recycled content by label type | Forest Stewardship Council | FSC-C licence code in the FSC public certificate search |
| Seedling logo (AS 4736) | Commercially compostable plastic - industrial facilities only | ABA, under trademark of European Bioplastics | Licence number against the ABA certified list |
| ABA Home Compostable (AS 5810) | Breaks down in a backyard compost bin | Australasian Bioplastics Association | Licence number against the ABA certified list |
| OK Compost / OK Compost Home | European compostability (EN 13432), common on imported lines | TUV Austria | Certificate number in the TUV Austria register |
| "Biodegradable" with no logo | Nothing - no standard, timeframe or conditions | Nobody | Ask for the standard and test report; treat as marketing until shown |
Certification applies to the finished product, not just the raw material - a certified resin can lose compostability once formed, coloured or laminated. Ask the trade desk which standard sits behind any DPack eco line.
Buyer beware
Greenwashing red flags on packaging claims
The ACCC's December 2023 guidance on environmental claims gave regulators sharp teeth: penalties for misleading claims reach the greater of $50 million, three times the benefit gained, or 30% of turnover - and in 2025 one household-brand supplier paid $8.25 million over recycled-content claims. Resellers are on the hook too: repeat a supplier's claim on your menu or website and you are expected to have taken reasonable steps to verify it. Ask harder questions when you see:
- "Eco-friendly", "green" or "sustainable" with no named certification - the ACCC specifically recommends avoiding these unqualified terms
- "Biodegradable" with no standard, timeframe or conditions
- "Compostable" without an AS 4736 or AS 5810 licence number, or without saying it needs a commercial facility
- "Recyclable" on PLA products - kerbside systems cannot process them
- Logos that look official but trace back to the seller, not an independent certifier

How to verify a supplier's eco claim - a five-minute checklist
- Name the standard. "Certified compostable" should finish the sentence: to AS 4736 (commercial) or AS 5810 (home). No standard, no claim.
- Find the licence number. An FSC-C code, ABA licence number or TUV certificate number, printed on the product, the carton or the spec sheet.
- Check the register. The FSC public certificate search and the ABA certified lists are free and take minutes.
- Match the scope. The certificate should cover the product you are buying, not just the supplier's business or the raw resin.
- Ask for the paperwork. A supplier making genuine claims can hand over certificates or test reports on request - the ACCC can demand substantiation within 21 days, so serious suppliers keep it on file.
- Sense-check the disposal story. If an item is commercially compostable, is there actually a facility or FOGO service near you that takes it? Certification without collection still ends in landfill.
Those six checks apply to every supplier - DPack included. Ask the trade desk on 0416 769 492 about the certification behind any eco line, or browse the eco-friendly packaging wholesale range - free Melbourne metro delivery on orders over $150 ex GST.

Common questions
Eco certification FAQs
What does FSC certified mean on packaging?
It means the paper or board fibre came from responsibly managed forests, tracked through chain-of-custody certification. The label type tells you more: FSC 100% (all certified fibre), FSC Mix (at least 70% certified or reclaimed inputs) or FSC Recycled (100% reclaimed material). Check the FSC-C licence code on the label in FSC's free public certificate search.
What does PLA mean on a cup or container?
PLA is polylactic acid, a bioplastic fermented from plant starch such as corn or sugarcane. It performs like conventional clear plastic but softens from about 40 degrees C, so it is used for cold cups and containers, while heat-treated CPLA handles hot-cup lids and cutlery at roughly 85 degrees C.
Is PLA packaging actually compostable?
Only in a commercial composting facility. PLA is certified to AS 4736 (commercial) but not AS 5810 (home) - it will not break down in a backyard bin and must never go in kerbside recycling, where it contaminates the PET stream. Whether a facility near you accepts it is a separate question: FOGO collection still reaches only a minority of Australian households, and acceptance rules vary by council.
What is the seedling logo on compostable packaging?
The seedling logo shows a product has been independently verified against AS 4736-2006, Australia's commercial compostability standard. The trademark is owned by European Bioplastics and administered in Australia and New Zealand by the Australasian Bioplastics Association. It is only genuine alongside a unique licence number you can verify on the ABA's public list.
What is the difference between AS 4736 and AS 5810?
AS 4736-2006 covers commercial composting: at least 90% biodegradation within 180 days under hot industrial conditions, plus plant and earthworm toxicity tests. AS 5810-2010 covers home composting at ambient 20 to 30 degree temperatures over up to 12 months - the tougher test. A home compostable item copes with the commercial route; a commercial-only item will not break down reliably at home.
How do I know if a supplier's eco claim is genuine?
Look for three things: a named standard (AS 4736, AS 5810, EN 13432 or an FSC label type), a licence or certificate number, and a match in the relevant public register - FSC's certificate search or the ABA's certified lists. The ACCC expects businesses that resell products to take reasonable steps to verify claims they repeat. If there is no paperwork, treat the claim as marketing.
