• Compact Fluorescent Light Bulbs/Fluorescent Tubes
  • Fluorescent light bulbs and tubes cannot be disposed of as regular garbage.  They are accepted at the Knott Landfill Hazardous Waste Facility.
  • Fluorescent light bulbs and tubes contain a small amount of mercury sealed within the glass tubing. When a fluorescent bulb breaks in your home, some of this mercury is released as mercury vapor and may pose potential health risks. The broken bulb can continue to release mercury vapor until it is cleaned up and removed from the residence. To minimize exposure to mercury vapor, EPA recommends that residents follow their cleanup and disposal steps. More information on CFLs at: www.epa.gov/cfl
