Green Lid Bin Contamination

Contamination (placing the wrong items into your green lid bin) is an ongoing problem and Council needs your help to reduce it. Contaminating the green lid bin has a huge impact on the composting process, sometimes causing entire truckloads of organic waste to be sent to landfill.

How can you help?

  • Make sure you only place food and garden waste into the green lid bin. If you're not sure what you can and can’t put in your green lid bin, read the information at the top of this page.
  • Only use the purple bags provided by Council, as these are the only bags that will break down properly at the composting facility.
