Fats, Oils and Grease Disposal Options


  • Fat, oil and grease buildup in wastewater (sewer) collection lines.

Keep Fats, Oils and Grease Out of Your Drain

When fats, oils and grease (F.O.G.) are poured into your sink drain, they are not broken down by the garbage disposal. F.O.G. enters the wastewater (sewer) system, where it cools and eventually congeals into a solid “ball” of grease, and can cause blockages.

Blockages can cause sewage to back up into your home or your neighbors’ home, posing health risks and increasing costs for residents. Blockages also can cause sewage to overflow from the sewer pipes and spill into creeks, rivers and streams, causing significant environmental damage.

You can help prevent F.O.G. from harming our sewer system by disposing of your used food grease responsibly. Never pour fats, oils or grease in sink drains or toilets.

F.O.G. is found in common food ingredients, including:

  • Meats (chicken, beef, fish, pork, bacon, turkey)
  • Dairy products
  • Cooking agents (lard, shortening, butter, cooking oil)
  • Certain condiments (mayonnaise, gravy, salad dressing, sauces, icing)
  • Food scraps
  • Used grease from turkey fryers is a major contributor of F.O.G., especially during the holiday season

Avoid using your garbage disposal for greasy food waste. Follow these simple steps instead:

  • Pour cooled F.O.G. into a sealable container and take it to your local oil recycling center.
  • Timberline Recycling Center, fcgov.com/trc
  • Larimer County Landfill, larimer.org/solidwaste/haz/household
  • Soak up remaining F.O.G. with paper towels and put them in the garbage.
  • Before you wash your dishes, scrape F.O.G. related food scraps into garbage, not compost.
