Cooking oil, fats and grease

Cooking oil or grease

Put up to two litres of cooking oil, fats, sauces, drippings and grease in your green cart for composting.

Special instructions

  • Solidfy fats and grease by letting it cool at room temperature or in fridge.
  • Mix oil with an absorbent material such as paper towel, sawdust or kitty litter and put the mixture in a certified compostable bag or paper bag. Place the tied up/rolled up bag in your green cart.
  • For larger volumes of cooking oil (over 2 litres) contact a cooking oil recycler (fees may apply)
