Australian Owned. Earth Focused. Bin Juice Free.
G'day! We are the team behind Compostar, based right here in Australia.
Like you, we were frustrated with the daily struggle of kitchen waste. We got tired of flimsy eco bin bags that leaked on the way to the kerb, and "green" products that turned out to be full of hidden plastics.
So, we decided to fix it. We combined 20+ years of manufacturing expertise with a passion for our local environment to create the ultimate Leak-Proof bin liner.
Our Story: Born from 500+ Kitchen Nightmares
The mandatory rollout of FOGO bins across New South Wales and Victoria is a massive win for our environment. But when we looked closely at how everyday households were coping, we saw a completely different picture.
We analysed over 500 real comments from local council forums and community boards. Everyday Australians were frustrated. Kitchens were messy. Standard eco bin bags were failing—acting as sealed moisture traps that accelerated foul odours, created toxic "bin juice", and turned summer green bins into breeding grounds for maggots.
We Followed the Science to Fix FOGO
We realised that standard non-breathable films defy biological laws when it comes to wet organic rubbish. Driven by peer-reviewed material science, CompoStar provides strictly AS 4736 (Commercial) Certified Compostable waste solutions, focusing entirely on our advanced reinforced kraft paper. By utilising a high-density fibre matrix and advanced Wet Strength Technology, we deliver structural integrity that survives 70-hour empirical stress tests, alongside active moisture evaporation that stops odours aerobically.
Waste Done Right: From Your Kitchen to the Council Bin
Our mission is simple: To Banish "Bin Juice" from Aussie Kitchens.
We believe going plastic-free shouldn't mean dealing with a messy kitchen. Our mission is to solve the nastiest part of food recycling: the leaks, the sludge, and the smells. By engineering a liner that can truly handle wet food waste, we make FOGO clean, hygienic, and easy for every family.
Whether you need a self-standing Small bin liner for your benchtop or heavy-duty FOGO Bin Liners for your wheelie bin, we ensure quality comes first.
- No Leaks: Our reinforced paper caddy liners breathe, preventing the dreaded "bin juice".
- No Plastic: Strictly no microplastics, just nutrient-rich compost.
- No Confusion: Designed specifically for Australian Green bin bags Council collection services. (Always check your local council guidelines for green bin acceptance.)
Beyond the Bin: Our Community Impact

Local Action, Hands-on
As a proud Melbourne-based team, we don't just engineer solutions—we roll up our sleeves. We are active supporters of Clean Up Australia, joining local community efforts to remove litter from our streets and waterways before it reaches the ocean.
Our Purpose: From Home to Forest
Our mission starts in your kitchen and grows into our forests. From designing high-performance leak-proof paper bags to protecting our iconic wildlife, we are dedicated to keeping Australia beautiful—one bag, one tree at a time.
The Material Science That Outperforms Standard Eco Bin Bags
To genuinely solve the FOGO waste crisis across New South Wales and Victoria, we had to move beyond standard compostable plastics. We engineered our strictly AS 4736 certified reinforced kraft paper to combat the three main biological challenges of kitchen waste collection.
Aerobic Odour Neutralisation
The end of the anaerobic "stink bomb."
Our research highlighted that standard compostable film bags trap moisture, acting as sealed environments that trigger foul-smelling anaerobic fermentation. Our solution? A highly breathable reinforced kraft paper matrix. By facilitating continuous oxygen flow and promoting aerobic breakdown, our liners neutralise severe odours at the source—no chemical masking needed.
70-Hour Wet Strength Technology
Zero "bin juice" leaks.
While local councils advise wrapping food scraps in paper, standard newspaper turns to a fragile pulp within hours. We developed an advanced Wet Strength Technology using a high-density fibre matrix. Subjected to a rigorous 70-hour empirical stress test, our paper securely contains heavy, wet organics without rupturing, keeping your kitchen caddy and kerbside bin pristine.
Disrupting the Pest Cycle
Preventing fruit flies and maggots.
Pests are biologically drawn to the acetic acid released by rotting, damp waste. By allowing up to 44% of trapped moisture to evaporate during indoor storage, our breathable paper actively destroys the wet "bin juice" pools at the bottom of the liner. This removes the exact damp breeding grounds that maggots and fruit flies rely on during warm Australian summers.
Certified & Trusted Across Australia
When we say "compostable", we verify it against the strictest Australian Standards. Compostar offers a range of solutions to suit both your home garden and your council bin.
- AS 4736 (Commercial Compostable): Our entire range — especially our heavy-duty paper caddy liners — is certified for commercial composting. This makes them certified FOGO Bin Liners designed to support Green bin bags Council services where permitted across Australia. (Always check your local council guidelines for green bin acceptance).
- AS 5810 (Home Compostable): Prefer to compost in your backyard? Our cornstarch Small bin liner rolls and pet bags carry the AS 5810 certification. Unlike fake eco bin bags, these are verified to break down in your home compost heap at lower temperatures.
Whether you use a worm farm or the council green bin, we have the strictly certified Food Scrap Bags to match your lifestyle.

Not Just a Bag, It's a Vote for a Greener Australia
The Choice
You choose Compostar certified compostable bags for your kitchen caddy.
The Action
You separate food scraps effortlessly. No yuck, no mess. Compliant with your local Council's FOGO standards.
The Transformation
Your waste bypasses landfill. Instead of generating methane, it travels to a local composting facility.
The Return
In 90 days, your "waste" becomes nutrient-rich soil, feeding Australian farms and gardens. The loop is closed.
Small Swaps, Massive Impact
500kg CO2-e Cut
Stop methane in its tracks. Every time you compost instead of using the general bin, you're literally keeping emissions out of the air. It's like taking a car off the road for 2 months — just by changing your bag.
Protect 45m² of Aussie Land
Protect the land we love. A year's worth of plastic bags takes up the space of a studio apartment in landfill. By switching to paper, you're saving that slice of Aussie land and turning waste back into soil.
Absolutely Zero Microplastics
Leave no trace. "Biodegradable" plastics often just break into harmful microplastics. Our paper waste bags break down completely into the earth. Zero plastic left behind.
The Truth: Not All Green Bags Are Created Equal
Raw Materials: Plants vs. Petroleum
Traditional plastic bags are made from crude oil and fossil fuels, depleting the Earth's resources.
Compostar bags are different. They are made from corn starch, plant-based materials. We turn renewable crops into everyday solutions, leaving fossil fuels in the ground where they belong.
FOGO Bin Compliance: Can I put it in the Green Bin?
Yes, but only if it's Compostar.
Many "biodegradable" bags are banned from FOGO bins because they contain plastic additives. To be accepted by your local Council, a bag must be certified to Australian Standard AS4736 (Always check your local council guidelines for green bin acceptance). Compostar holds this certification, meaning our bags are welcomed by composting facilities across Australia.
The "Biodegradable" Trap vs. True Composting
Beware of bags labeled just "Biodegradable." Often, these are just regular plastic that breaks down into millions of invisible microplastics, poisoning our soil and water.
Compostar is certified "Compostable." This means it doesn't just break into pieces; it biologically decomposes into non-toxic, nutrient-rich soil food within 90-180 days in a commercial facility. Zero microplastics, zero guilt.
Strength & Durability: Will it leak?
The biggest myth is that eco-friendly bags are weak. We engineered Compostar to prove them wrong.
With a reinforced star-sealed bottom and extra-thick plant-based resin, our bags are designed to hold heavy kitchen scraps without tearing or leaking. It’s the same convenience you’re used to, just without the plastic waste.
