Biodegradable Packaging for Perth Food Businesses
, by Paul Slee, 7 min reading time
Switching to biodegradable packaging? Learn what actually breaks down, what WA law requires, and how to choose the right eco packaging for your food business.
If you run a café, food truck, or takeaway in Perth, you've probably fielded questions from customers about your packaging. And if you haven't yet, you will. Sustainability is no longer a nice-to-have — it's something your customers notice, and increasingly, something WA legislation is pushing you toward anyway.
But "biodegradable packaging" is one of those terms that gets thrown around a lot without much precision. Not everything labelled eco-friendly actually is. This post breaks down what the terms mean, what WA rules apply, and how to make a sensible choice for your business without blowing your budget or your storage space.
What Does "Biodegradable" Actually Mean?
Biodegradable means a material will break down naturally over time through the action of bacteria, fungi, or other living organisms. The problem is that almost anything will biodegrade eventually — even conventional plastic, given enough centuries. So the word on its own tells you very little about how quickly something breaks down or under what conditions.
When you're buying packaging for a food business, the distinctions that actually matter are:
- Compostable: Breaks down within a defined timeframe (typically 90 days) in the right conditions, leaving no toxic residue. This is the most meaningful standard for food packaging.
- Home compostable vs. commercially compostable: Home compostable products break down in a backyard heap. Commercially compostable products require the higher temperatures and controlled conditions of an industrial composting facility. If your city's kerbside organics bin accepts certified compostables, commercially compostable packaging can go in there — but check with your local council first.
- Recycled content: Not the same as biodegradable, but still a meaningful sustainability credential. Packaging made from recycled paper or card reduces demand for virgin materials.
- Recyclable: Can enter the recycling stream, but only if it's clean. Greasy pizza boxes and food-soiled paper cups are generally not accepted by kerbside recycling.
Look for certifications like AS 4736 (Australian standard for commercial compostability) or AS 5810 (home compostable). The Australasian Bioplastics Association's seedling logo or the European OK Compost mark are also widely recognised. If a product doesn't carry one of these, the biodegradable claim is hard to verify.
WA Single-Use Plastic Bans: What You Need to Know
Western Australia has been progressively phasing out single-use plastics under the Waste Avoidance and Resource Recovery Act. Bans on items like plastic straws, cutlery, plates, and certain containers are already in effect, with further restrictions staged over time.
What this means practically is that if you're still buying conventional plastic cutlery, plastic straws, or polystyrene food containers, you may already be non-compliant — or you're about to be. Switching to certified-compostable or fibre-based alternatives isn't just an ethical choice; it's a compliance requirement.
The good news is that the range of genuinely functional, commercially certified alternatives has improved considerably. Sugarcane (bagasse) containers, CPLA cutlery, kraft paper bags, and lined paper cups are all widely available and perform well in food service conditions. They're not always identical in price to the cheapest plastic options, but the gap has narrowed, and the compliance risk of staying on plastic is real.
If you're unsure whether a specific product you're currently using is affected, the WA Waste Authority website has the full list of restricted items.
Common Biodegradable Packaging Materials and Where They Work
Different materials suit different applications. Here's a practical overview:
- Sugarcane (bagasse): Made from the fibrous residue left after sugarcane is processed. Handles heat well, is moisture resistant, and is suitable for hot meals, soups, and baked goods. Usually commercially compostable. A solid choice for takeaway containers and clamshells.
- Kraft paper and paperboard: Good for bags, wrapping, sandwich boxes, and bakery packaging. Recyclable when clean, and often made with recycled content. Not suitable for wet or oily foods without a lining.
- PLA (polylactic acid): A bioplastic derived from corn starch or sugarcane. Used in cold cups, lids, and some containers. Looks and feels like conventional plastic. Important caveat: PLA is commercially compostable only — it does not break down in home compost or regular recycling and must go to an industrial facility. Don't use PLA cups if your customers are likely to put them in a recycling bin.
- CPLA: A crystallised form of PLA used for cutlery and hot cup lids. Can handle higher temperatures than standard PLA. Commercially compostable.
- Bamboo and wood: Often used for skewers, cutlery, and small plates. Generally home compostable. Check for chemical treatments or coatings that may affect compostability.
- Paper cups with water-based lining: A newer alternative to the traditional PE-lined paper cup, which is notoriously difficult to recycle. Water-based or aqueous linings are more compatible with recycling and composting streams, though availability varies.
How to Choose the Right Biodegradable Packaging for Your Business
Before you order anything, work through these questions:
- What conditions does the packaging need to survive? Hot food, cold food, oily food, wet sauces — each puts different demands on materials. A packaging option that works beautifully for dry pastries may fall apart with a noodle dish.
- What will your customers actually do with it? If they're eating on-site and you have a commercial compost collection service, certified compostable packaging makes sense end-to-end. If they're taking food home and your area doesn't have kerbside organics, commercially compostable packaging may just end up in landfill anyway — in which case recyclable fibre-based options might be more honest.
- Do you need certified products for compliance or procurement reasons? Some councils, events, and venues require suppliers to use certified compostable packaging. Check what certification standard they require before you order.
- What's your volume? Eco packaging generally costs more per unit at low volumes. If you're going through significant quantities, buying in larger runs through a wholesale supplier will bring your unit cost down substantially.
- Can you standardise your range? Using fewer SKUs reduces storage requirements and simplifies reordering. A good supplier will help you find products that cover multiple uses rather than stocking a different container for every item on your menu.
One practical tip: don't let perfect be the enemy of good. Moving from conventional plastic to a quality kraft paper or bagasse alternative — even if it's not certified home compostable — is still a meaningful improvement. Start with your highest-volume items and work from there.
Talking to Your Customers About Your Packaging Choices
Your customers are increasingly eco-aware, and many will appreciate knowing what you're using and why. You don't need a polished sustainability policy — a simple, honest explanation goes a long way.
If you're using commercially compostable packaging, let customers know it goes in the green organics bin (if your council accepts it) rather than recycling. A small note on your packaging or counter can prevent contamination and actually gets the material to where it can break down properly.
If you're making the switch gradually — starting with cutlery, then cups, then containers — that's worth communicating too. Customers generally respect businesses that are making genuine progress rather than just slapping a green label on business as usual.
