Food and garden waste is collected weekly and is recycled into organic compost. By putting the right stuff in the green bin, you’re making it possible for us to produce locally-made compost and reduce how much is sent to landfill.
We accept all food waste and garden waste in your green organics bin:
Make sure flax, cabbage trees or anything larger than 70cm in length or 7.5cm in diameter, go in the red bin as they can break the machinery at our organics processing plant.
It has a handy lookup tool so you can find out what goes in each bin as well as reminders to take the bins out each week.
Each year, the organics processing plant processes approximately 45,000 tonnes of organic material from green bins.

Our processing plant has a very low contamination rate compared to other plants in Australasia. This is all thanks to you putting only the right things into your green bin.
The contamination rate is currently around 2.5% but the Council aims for less than 1%. Contamination comes from items like plastic bags containing food waste, ash and sawdust.
Food scraps can be wrapped in newspaper before putting them in your green bin and ash and sawdust must be put into your red bin.
Although some compostable bags are able to be home composted, they are not compostable at the Council’s processing plant. This is because they do not break down within the twelve-week processing time frame
We can’t accept, takeaway cups or lids in the green bins in Christchurch. They must be put in the red bin.
Some companies, both locally and nationally, have branded their cups as either biodegradable or compostable but unfortunately, they can’t be processed at our organic processing plant.
We aim to reduce as much contamination as possible. The contents of the green bin go to the Council’s organics processing plant, where it is turned into compost. If a truckload is considered too contaminated by non-compostable items such as take-away cups and plastic bags, then the whole load may have to go to the landfill.
