Quick Note on CFL's and the trace amount of mercury used to help generate light:

CFL's should be treated like other electronic equipment and disposed of properly such as at Recycle Utah in Park City, the Salt Lake Valley Solid Waste Facility or other such collection sites (ie. just not landfilled).

"People concerned about the environment and their health can buy these CFLs with a clear conscience," Noah Horowitz, senior scientist with the Natural Resources Defense Council, said in a statement released by Wal-Mart.

"In fact," he added, "the energy savings delivered through the use of CFLs will actually reduce more mercury pollution from coal-fired power plants than is added through manufacture of the bulbs."

That's because Environmental Protection Agency figures show that coal-fired power plants emit four times more mercury to power an incandescent bulb than to power a CFL, Wal-Mart said.
