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.)

Plastic and cornstarch liners trap moisture, which causes food to rot quickly, creating terrible summer smells and attracting fruit flies. Our kraft paper keeping your waste drier, locking in odours, and stopping the mess. Plus, they never tear easily!

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.
