Fats, oils and grease

Food service businesses: You are required to safely dispose of commercial quantities of fats, oils and grease. For more information, visit Fats, oils and grease - Protect your business

Cooking fats, oils and grease (FOG) cause a lot of problems if they're disposed of down the drain - clogged pipes, reduced plumbing flow, odours, sewer backups, environmental damage and expensive repairs for Calgary's wastewater system. They should never be flushed down sinks, drains or toilets.

Keep these items out of your sinks, drains or toilets:

  • Fats: Butter, margarine, shortening, lard, etc.
  • Oils: Salad dressings, cooking or deep fryer oils, olive oil, sauces, etc.
  • Grease: Chicken, hamburgers, bacon, etc.

How to put fat, oil and grease into your green cart

Keep fats, oils and grease out of your drain by following these easy tips in the kitchen.

  • Residential quantities (two litres or less) of fats, oils and grease should be disposed of in the green cart, not the garbage (black cart) and not down the drain.
  • Always wipe cooking equipment and scrape dishes before washing.
  • Solidify your oil by mixing it with an absorbent material such as paper towels, then place it in a certified compostable bag or paper bag and place it in your green cart.
