Save Your Turkey Fat & Recycle for Biodiesel Fuel

Help protect pipes and save money by recycling used cooking oil and fats.

Wondering what to do with the leftover fryer oil and kitchen grease after the big holiday feast? Don’t pour it down the drain – grease sticks to the inside of sewer pipes and can build up to such a point that it blocks the entire pipe, leading to expensive and unpleasant clean-ups.

The King County Department of Natural Resources and Parks has partnered with General Biodiesel to provide residents with a safe, environmentally-friendly way to dispose of used cooking oil and grease so it can be recycled instead of ending up in landfills or drains.

During the holiday season, General Biodiesel will provide several convenient drop-off locations throughout King County where people can bring their unwanted cooking fats and grease. Locations are open 24/7, and there is no minimum amount. For a complete list of drop-off locations, visit

To ensure safe and secure transport and disposal of your fats and grease, King County and General Biodiesel suggest putting the cooled material from fryers, pots or pans in a sealed container.

At the disposal tank, slowly pour the grease into the collection container to avoid splatter and mess. Be sure to close the community collection tank lid when you’re finished. Take your own containers home and leave nothing behind but the oil you deposited.
