How do you dispose of the bulbs? Well, CFL bulbs contain an extremely small amount of mercury; about 1/100 of the amount in a common household thermometer. The primary source of mercury emissions in the U.S. is coal-fired power plants. An unbroken CFL does not pose a health risk. Expended CFL's should be disposed of properly, in the same manor as other household hazardous waste products like paint, batteries and non-digital thermostats. The concern is valid and lies in concentrations of mercury accumulating in our landfills over time.

A coal power plant powering an incandescent light bulb will release more mercury into the air than is contained in a CFL. Although the CFL mercury issue is a concern, the net result of mercury released into our environment, given the reduced power requirements of a compact fluorescent bulb over its lifetime, remains less. Many municipalities offer programs for safe collection of hazardous household waste. Never incinerate a compact fluorescent bulb as means of disposal.

If a bulb breaks never inhale the vapor. Also, you should never use a vacuum to clean it up. Instead sweep the pieces together with a brush or broom, not with your hand. Clean the glass with a rag or towel then seal it into a plastic bag.

Dispose of expended or broken CFL’s at you local Household Hazardous Waste (HHW) collection site. If your local HHW Collection Site does not accept CFL's, check with local authorities. Many CFL retail outlets also offer safe disposal or recycling.

CFL's are a simple way to make a big difference in the amount of energy we use. And you can save a lot of money at the same time!
