Acceptable compostable bags and liners

Only certified compostable bags or paper liners can be used to line your kitchen pail since they're guaranteed to completely breakdown during the composting process. While lining your pail is a great way to keep your kitchen pail clean and reduce odours, it's not required.

Unacceptable liner bags

The following bags are not accepted in the Green Cart program:

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.​​
