Proper disposal of chemicals, oil, and hazardous waste is very important to prevent the materials from leaching into the water and soil or otherwise polluting the environment. The Shawnee County Household Hazardous Waste facility accepts household and automotive chemicals, cooking oil, batteries, electronics, paint, aerosol cans, and CFL lightbulbs. They also accept medications and sharps (needles, syringes, lancets) in a solid plastic or metal container). You can purchase used paint from the facility for a small fee.
