Save your pipes by taking used cooking oil to a recycling facility

  • Written by Woodinville Weekly Staff

General Biodiesel, a King County partner, will collect used cooking oil so that it won’t clog pipes but will be given a second life as biodiesel fuel

Making plans for holiday dinners should include having a plan for dealing with the leftover cooking oil and kitchen grease. Pouring it down the drain will clog pipes and cause costly headaches.

King County and General Biodiesel have set up 15 easy-to-find locations throughout the county where used cooking oil and grease can be dropped off so that it can be recycled and given a second life as sustainable biodiesel fuel. Each year, thousands of taxpayer dollars are spent clearing public sewer lines that are blocked by grease that shouldn’t have gone down the drain. Residents can spend hundreds more in costly emergency home plumber visits.

Collect the oil and grease from fryers, pots, and pans in a safe transport container before taking it to a recycling depot.

Current locations in King County include: Auburn, Bellevue, Burien, Federal Way, Kirkland, Mercer Island, Renton, Sammamish, Seattle and Shoreline. For the full list of all site locations and directions, visit: information is available at or by calling (206) 684-1280 or 711-TTY.
