Compact Fluorescents: What You Should Know
Get Energy Active has received a number of e-mails about compact fluorescent light bulbs (CFLs). Here’s some information to help answer your questions and address your concerns.
Do CFLs contain mercury?
Yes. Mercury is an essential ingredient in CFLs, allowing them to be efficient light sources. According to the U.S. Environmental Protection Agency, CFLs contain a very small amount of mercury—about 4 to 5 milligrams (mg)—that is sealed within the bulb’s glass tubing. The amount of mercury in a CFL is approximately equivalent to the tip of a ballpoint pen. By comparison, older home thermometers contain 500 mg of mercury and older home thermostats contain up to 3,000 mg. While there is currently no substitute for mercury in CFLs, manufacturers have reduced the amount of mercury in fluorescent lighting products over the past several years.
How do I dispose of a CFL?
It is important to dispose of your CFLs properly upon burnout or breakage. Recycling programs are beginning across the country. However, if recycling is not available in your area, place the CFL in a sealed plastic bag and dispose of it the same way you would batteries, oil-based paint, and motor oil at your local Household Hazardous Waste (HHW) Collection Site. If your HHW does not accept CFLs, simply seal the CFL in a plastic bag and place it with your regular trash.
While CFL recycling programs are not yet available in all areas, you may be able to find one near you. Visit www.Earth911.org, or call 1-800-CLEAN-UP. On the Web site, enter your zip code to find local disposal options. You can also check with your local government or local waste management agency for recycling options in your area.
If a CFL breaks in your home, open nearby windows to increase ventilation and sweep up the broken fragments—do not use your hands or a vacuum cleaner. Place all fragments in a sealed plastic bag and follow the disposal instructions above.
Why should I use CFLs in the first place?
The EPA recommends the use of CFLs for the many benefits they offer, including reduced energy use and cost savings. CFLs use two-thirds less energy than incandescent light bulbs and last up to 10 times longer. Using CFLs also helps the environment by saving energy and reducing emissions of nitrogen oxides, carbon dioxide, and other air pollutants.
