What do bacon, ice cream, and peanut butter all have in common? They are more than just tasty treats. They are also sources of fats, oils, and grease, also known as FOG.

While fats, oil, and grease add extra flavor to your food, pouring FOG down the drain can leave a real mess in the Lawrence sewer collection system and impact our streams.

FOG creates clogs that can back up sewage into your street, yard, or home and can even send it spilling into a neighborhood stream! Think of it this way – if it can clog arteries in the body, then it will probably clog the sewer pipe. Fortunately, cleaning up FOG is as easy as doing a few simple things around the kitchen.

You can Help!

  • Before washing dishes, use a paper towel or a scraper to wipe FOG from dishes and dispose of it in the trash or compost.
  • Use sink strainers to catch food waste.
  • Put food scraps in the trash or compost bin, not through the garbage disposal.
  • Contain cooking oil and grease for proper disposal.  See below for disposal options.

Sources of Fats Oil and Grease

FOG can come from a variety of sources, many of which we forget contain FOG. Examples include:

Baked Goods


Butter & Margarine

Cooking Oil

Dairy Products

Fried or sautéed Foods



Meats (including trimmings & skins)


Peanut Butter


Salad Dressings

Sauces & Gravy



Disposal Options

Fat and grease can be cooled and contained for trash disposal in a sealed container.  Small amounts of cooking oil, less than a quart, can be absorbed or frozen for trash disposal.  Kitty litter works well for absorbing small amounts of cooking oil.  Cooking oil can also be recycled through the City of Lawrence Household Hazardous Waste Facility.
