Oil and Grease

Fats Oils and Grease Program



Fats, Oils and Grease are by-products of cooking and are found in many foods. Fats, Oils and Grease become a problem for residents, businesses, and the CNMI when they are not disposed of properly.

When Fats, Oils, and Grease are disposed of down the drain they cause a blockage in the plumbing (sewer) lines and do not let wastewater flow to the treatment plant. Wastewater then backs up and overflows into your home, business, or out the manhole in the street. These overflows are unsanitary and costly to clean up. They cause higher sewer rates.

The following is an example of some of the products in your kitchen that should NOT be disposed of down the drain:

• Meat Fats                                                      • Food Scraps

• Cooking Oil                                                   • Sauces

• Dairy Products                                             • Baked Goods

• Shortening                                                    • Buttter/Margarine   

Here are some helpful tips on how Fats, Oils and Grease can be properly managed in your kitchen:

  • Let cooking oil and grease cool, pour into container and throw in trash. Do not pour oil and grease down the drain;
  • Remove oil and grease from kitchen utensils, equipment and food preparation areas with scrapers or paper towels and throw in trash. Keep grease out of wash water;
  • Use sink strainers to catch food waste and throw food scraps in trash. Do not use a garbage disposal to dispose of excess food waste.
