How to compost cooking oil, fats and grease
- If you have larger amounts of spoiled liquids (more than two litres) 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).
- Liquids in the green cart cause problems through the waste collection system, as collection trucks are not designed to carry liquids.
- For more than 2L of cooking oil, you can also drop off at Eco Dine, a local oil recycling company. To drop off oil, visit Eco Dine’s main facility located at 8489 40 Street SE. Contact Eco Dine for more information.
- 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 or paper bag.
- Place the tied up/rolled up bag in your green cart.
Tip: Never flush fats, oils or grease down your toilet, sink or drain. They can damage your home's pipes as well as the environment.
