Used Cooking Oil

Used cooking oil and other grease accumulated while cooking should not be poured or washed down the drain. These can clog and damage sewer pipes, causing nasty overflows, messy spills on streets, and expensive clean-up costs. Save your pipes and recycle your used cooking oil instead. This service is free! All collected cooking oil will be recycled into biodiesel fuel by General Biodiesel. We know the tank can look a little gross, but better the tank than clogging your pipes at home! If you do not want to drop off your cooking oil, you can also throw it away in the garbage in a sealed container.

This tank is for cooking oil only - NO motor oil.

How to Recycle Used Cooking Oil in Kirkland

Cooking Oil Tank   NKCC UCO Mappouring used cooking oil into container
  1. The cooking oil tank is located at the north end of the North Kirkland Community Center parking lot, 12421 103rd Avenue NE. (Drive past the building and enter the back parking lot.) Lift the lid and pour your used cooking oil into the collection tank. The collection tank is unlocked 24 hours/7 days a week. It is open for use during the pandemic.
  2. Close the tank lid when you are finished.
  3. Take the container you brought your oil in home to recycle, reuse, or throw away. Do not leave the container at the tank!
If the tank is more than half full, please let us know at or (425) 587-3812 so we can arrange for the oil to be emptied. You can also contact General Biodiesel directly.

If you see that someone has left full oil containers on the ground, please let us know at or (425) 587-3812 so we can empty them into the tank to make sure they don't spill and make a mess on the parking lot. (If possible, it would be a great help to us if you could empty any containers of cooking oil into the tank to save staff from making a special trip. We also don't monitor our hotline on weekends, so if you encounter this on a weekend it would be extra helpful!)

If you see a spill of oil on the ground, or accidentally spill any yourself, please let us know! We need to clean up spills to prevent the oil from getting into our storm system and flowing into Lake Washington! Contact our 24/7 Spill Hotline at (425) 587-3900 so a crew can clean it up ASAP.
