Cooking Oil Recycling Effort (C.O.R.E.)

Used cooking oils are a serious problem for home plumbing and Hillsborough County's wastewater collection system. Cooking oil that is poured down the drain gels and solidifies inside pipes, sewage lines and sewage lift stations, constricting water flow. That can back up home plumbing, and also cause equipment to malfunction, leading to sewage spills, overflows onto streets, and foul odors in homes and neighborhoods. Hillsborough County's Cooking Oil Recycling Effort is for residential cooking oil. Commercial and industrial customers must contact a licensed commercial grease hauler for cooking oil disposal.

How I can make a difference?

  1. Carefully pour cooled cooking oil into a large, sturdy plastic or wax-coated container, such as the original container, a juice carton, or a Cooking Oil Recycling Effort jug
  2. Cap the container and store in a cool, safe location
  3. Don’t mix the oil with any other liquids or products
  4. Once the container is full, bring it to a Cooking Oil Recycling Effort station or to one of our Household Hazardous Waste Collection Centers
