Cooking oil (pour out of container/fryer)

  • Put into your green cart

Put used cooking oil, fats and grease into your green cart for composting.

  • Solidify 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. Put the mixture in a certified compostable bag to keep your pail tidy.
  • If you have larger amounts of cooking oil, try putting small amounts in your kitchen compost every day until you have disposed of the entire amount. Only put in what can be absorbed by the contents of your kitchen pail (fuller kitchen pails can absorb more liquids than emptier ones).
  • Place the tied up compostable bag in your green cart.
