3.7 Fats, Oil, & Grease (FOG)

In a residential program in support of sustainability efforts, containers and liners are being provided for all apartment kitchens and residential student kitchens to collect Fats, Oil, and Grease (FOG) from food preparation and kitchen clean up. FOG is found in such things as meat fats, food scraps, lard/shortening, baking goods, butter/margarine, cooking oil, sauces and dairy products.

Why should we care about FOG?

Residential households contribute FOG build-up in the sewer lines because of the amount of grease washed into the plumbing system, usually through the kitchen sink. Sewer lines are at major risk of sewer backup if residents don't properly dispose of FOG.

What can we do?

The easiest way to solve the grease problem is to keep FOG out of the sewer system in the first place and follow the easy disposal tips listed below.

What are some proper FOG handling and storage methods?

  • Never pour grease, fats, or oil down the sink or garbage disposal.
  • Pour FOG into jars, cans, and plastic tubs (Careful, the liquid may be hot!) or containers which are being provided for residential kitchens. Let contents cool and solidify. When the container is full, throw away with the trash.
  • Mix cooking oil with an absorbent material such as cat litter or coffee grounds, place in a lidded container for disposal with the trash.

For greasy pans, pour off the grease into a container and use a paper towel to wipe out the remaining grease in the pan prior to washing it.

Containers and liners will be distributed to apartment kitchens and residential kitchens at opening. Extra containers and liners are available in the Residence Life.
