Used Cooking Oil Recycling Suspended

The Thurston County Waste and Recovery Center (WARC) has suspended its used cooking oil collection program at HazoHouse. The suspension comes in response to new traceability guidelines set by Mahoney, the current collection and recycling vendor, which prevent them from continuing collection at the WARC. 

Residents should solidify used cooking oil with a commercial oil solidifier or stearic acid before placing it in the household garbage. Visit the Household Hazardous Waste page for more information. Questions can be directed to 360-867-2491 or
