Mercury Contents
Compact Fluorescent Light (CFL) bulbs contain small amounts of mercury, an essential ingredient for CFL bulbs to produce light. While the amount of mercury inside a CFL's glass tubing is only about 5 milligrams - roughly the amount that would cover the tip of a ballpoint pen - it is still essential to handle and recycle CFLs responsibly.
Ace Hardware Recycling Program
With another Smart Idea, ComEd has partnered with the Illinois Environmental Protection Agency (IEPA) and Ace Hardware to recycle CFLs. Just bring your used CFLs to any participating Ace Hardware store near you. Ace will then dispose of your used CFLs in Environmental Protection Agency (EPA)-approved recycling containers free of charge.
Home Depot Recycling Program
In addition, Home Depot has also launched a national in-store CFL recycling program, free at all its locations.
