Biodegradable Packaging for Perth Food Businesses
, by Paul Slee, 6 min reading time
Switching to biodegradable packaging? Learn what to look for, how WA plastic rules affect you, and where to source certified-compostable options in Perth.
If you run a cafe, food truck, or takeaway in Perth, you've probably had a customer ask about your packaging. Or you've had to quietly retire your old plastic containers after WA's single-use plastics legislation started biting. Either way, the shift toward biodegradable packaging isn't just a trend — it's now part of doing business in Western Australia.
The problem is that "biodegradable" has become one of those words that gets thrown around loosely. Not all biodegradable packaging is the same, and some products labelled that way won't break down in any meaningful timeframe unless they end up in an industrial composting facility. Buying the wrong thing wastes your money and doesn't actually solve the problem.
This guide cuts through the noise and helps you make a sensible, informed choice for your business.
What "Biodegradable" Actually Means (and Why It's Not Enough on Its Own)
Technically, almost everything biodegrades eventually — including conventional plastics, given enough centuries. When packaging is marketed as biodegradable, what matters is how fast it breaks down, under what conditions, and what it leaves behind.
There are a few distinct categories worth understanding:
- Compostable packaging breaks down into non-toxic organic matter within a defined timeframe, either in a home compost or an industrial composting facility. This is the gold standard. Look for products certified to Australian Standard AS 4736 (industrial composting) or AS 5810 (home composting).
- Biodegradable plastics are a mixed bag. Some are genuinely plant-based and compostable. Others are conventional plastics with additives that cause them to fragment into microplastics — which is arguably worse than leaving the plastic intact.
- Recyclable packaging (paper, cardboard, certain plastics) isn't the same as biodegradable, but it still reduces landfill impact if your customers actually recycle it.
For a food business, certified-compostable is generally the most defensible claim you can make to customers. If a product carries a certification mark from the Australasian Bioplastics Association (ABA) or a recognised international body, you have documentation to back up what you're telling people.
WA's Single-Use Plastics Laws: What You Need to Know
Western Australia has been progressively phasing out single-use plastics. Since 2023, a broad range of items — including certain plastic plates, bowls, cutlery, straws, and drink stirrers — have been banned from supply. The regulations continue to expand, so if you haven't reviewed your current packaging lineup recently, now is a good time.
The practical upshot for food businesses is straightforward:
- Plastic cutlery is out. Paper, bamboo, or CPLA (a compostable bioplastic) alternatives are in.
- Expanded polystyrene (EPS) containers are banned. You need to source alternatives — sugarcane bagasse, moulded paper pulp, and kraft board containers are the most common replacements.
- Plastic straws are banned. Paper and compostable alternatives are the standard replacement.
Beyond compliance, there's a commercial angle here too. Perth consumers are paying attention. A business still handing out polystyrene boxes in 2025 will hear about it.
The Most Useful Biodegradable Packaging Materials for Food Businesses
Here's a practical rundown of what actually works in a commercial food setting:
- Sugarcane bagasse — Made from the fibrous pulp left after sugarcane is processed. Naturally compostable, handles hot and cold food well, and is reasonably grease-resistant. A solid choice for takeaway containers, plates, and bowls.
- Kraft paper and paperboard — Widely used for bags, wraps, sandwich boxes, and hot drink cups. Unlined kraft is compostable and recyclable; cups and containers lined with PLA (a plant-based plastic) are compostable in industrial facilities. If the liner is conventional polyethylene, the item is neither recyclable nor compostable — so check before you buy.
- PLA (polylactic acid) — A bioplastic made from corn starch or similar crops. Used for clear cold cups and lids, often labelled as compostable. Important caveat: PLA requires industrial composting to break down properly. It won't degrade in landfill on any useful timescale and shouldn't go in home compost bins. Still a better choice than petroleum-based plastic, but be honest with your customers about what to do with it.
- CPLA cutlery — A crystallised, heat-resistant version of PLA. The most common compostable replacement for plastic knives, forks, and spoons. Handles hot food better than standard PLA.
- Bamboo — Used for cutlery, skewers, and some containers. Naturally fast-growing and low-impact. Biodegrades in most conditions.
- Moulded paper pulp — Often used for egg carton-style trays and some food containers. Compostable and sturdy. Increasingly common in bakery and deli applications.
How to Choose the Right Biodegradable Packaging for Your Operation
The right answer depends on your food type, your customer base, and your volume. Here are the questions to work through:
What temperature does your food reach? Hot soups, curries, and fresh-from-the-fryer items need containers that won't warp or leak. Bagasse and double-wall kraft board handle heat well. Standard PLA cold cups are not appropriate for hot drinks.
How greasy or liquid is your product? Grease is the enemy of uncoated paper. If you're serving something oily or saucy, you need a container with some barrier layer — either a grease-resistant coating or a material like bagasse that naturally handles oil better.
Does your customer have access to industrial composting? This is the honest question most suppliers skip. If your customers are throwing packaging into a general waste bin, the compostability claim is largely academic. That doesn't mean you shouldn't use compostable packaging — the regulatory compliance and customer perception benefits are real — but it's worth knowing the full picture.
What volume are you ordering? Eco-friendly packaging generally costs more per unit than conventional plastic. At low volumes, the difference per serve might be negligible. At high volumes, it adds up. Work out your per-serve cost increase and factor it into your pricing if needed. Many businesses absorb a small increase; others add a few cents to takeaway orders.
Do you need certified products? If you're making public sustainability claims — on your menu, socials, or in tender documents — certified-compostable products give you something concrete to point to. If you're just trying to stay compliant with WA regulations, the spec sheet matters more than the certification mark.
Avoiding Greenwashing When Talking to Customers
Once you've switched to better packaging, it's tempting to shout about it. That's fair — but be precise about what you're claiming. A few things to keep in mind:
- Say "compostable" only if the product is certified as such. Saying "eco-friendly" or "sustainable" is vague enough to be defensible; saying "compostable" when it isn't is a problem.
- If you're using PLA cups, let customers know they need to go to an industrial composting facility — not the home bin, not the recycling bin.
- If your local council accepts compostable packaging in FOGO (food organics and garden organics) bins, that's worth communicating to customers. It makes the eco claim genuinely meaningful.
Customers who care about sustainability will appreciate the honesty. It builds more trust than a generic "green" label.
