In 2026, using non-certified bags can lead to bin rejection or hefty fines for businesses. Compostar provides a reliable, plastic-free solution for every Aussie household and commercial kitchen.
How do your bags solve the "Bin Juice" and fruit fly problem?
Unlike traditional plastic liners that trap moisture and heat, our leak-proof paper allows waste to breathe.

Will the paper bag leak if I put wet food scraps in it?
No! Compostar bags are engineered with a reinforced, leak-proof square base. They are designed to handle wet kitchen waste—like watermelon rinds, leftover curries, and prawn shells—without breaking or leaking "bin juice" onto your benchtop.
Can I put these bags in my council FOGO green bin?
Yes, our paper compost bags are officially certified to the Australian Standard (AS 4736). This means they are completely safe and approved for food organics and garden organics (FOGO) council bins across Sydney, Melbourne, and all of Australia.(Always check your local council guidelines for green bin acceptance.)
Why use paper bags instead of green cornstarch bin liners?

Warming Australia. Real consequences.
2026 Victorian bushfires are not a coincidence — they are a consequence of a warming climate.
Carbon emissions are the root driver of global warming. Beyond fossil fuels, industrial pollution, and deforestation, high-carbon linear consumption — especially plastic waste — continues to fuel climate disasters.
Australia's warming reality:
• Since 1910, average temperatures have risen by ~1.51°C
• Every decade since the 1950s has been warmer than the last — a 70+ year accelerating trend
At around 1.5°C of warming, severe climate impacts are already here — with escalating bushfire risk among the most devastating.
