The City will be delivering another sample of compostable liner bags to households in fall 2021 for year two of the pilot project. The sample liner bags that households received at the start of the pilot project were expected to last approximately one year, based on an average use of two bags per week. We understand that households have diverse requirements and will use liner bags at different rates. If you run out of liner bags, they can be purchased at most major grocery stores, home and garden centres, and online retailers. Liner bags must be certified BPI compostable. Alternatively, you can line your kitchen pail with a paper bag, newspaper, or simply use it without a liner.
