How to Properly Dispose of Oils and Hazardous Materials
Do not pour grease or oil down the drain; they can clog pipes and contaminate water. Let them cool and solidify in a sturdy container (such as a glass jar). For used cooking oil, we have the annual “Grease Drive” event in Tucson, organized by Grecycle and Pima County. The event is scheduled for the fall; the next event will be in January 2026.
Used motor oil should be taken to authorized recycling centers or repair shops. Some recycle it for biodiesel or lubricants.
Advanced Auto Parts: Most accept used oil free of charge.
