Only certified compostable bags or paper liners (e.g. newspaper/flyers or paper bag) 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.
