When green carts are delivered, residents will receive a starter supply of compostable bags for their kitchen pail. Using compostable bags or paper liners (e.g. paper bag or newspaper/flyers) is an easy way to keep your kitchen pail clean and reduce odours as part of using your green cart.
Only certified compostable bags, newspaper or paper bags are accepted in the program since they're guaranteed to completely breakdown during the composting process and become a part of the finished compost. To learn more about what items to put in your green bin, visit our What Goes in your Green Cart page.

Unacceptable liner bags
The following bags are not accepted in the Green Cart program because they don't breakdown during the composting process and will diminish the quality of the finished compost.
No plastic bags
Plastic bags prevents the flow of air, which is essential during the composting process. Since they don't breakdown, they end up diminishing the quality of the finished compost.
No oxo-biodegradable or biodegradable bags
Biodegradable bags are made from plastic. These bags break apart into small plastic pieces that will diminish the quality of the finished compost.
