It’s Like Christmas Tonight
This is a very, very interesting late night at the Crabitat. I just finished the previous post and then found this little jackpot of all jackpots for the day. San Francisco bans plastic bags and cuts down more trees as a result. That's amusing, the next item is hilarious. There have been repeated mentions in the news lately of efforts to ban incandescent light bulbs and mandate the use of compact fluorescent bulbs instead. Only it turns out those bulbs pose another - really large - problem.
With an estimated 150 million CFLs sold in the United States in 2006 and with Wal-Mart alone hoping to sell 100 million this year, some scientists and environmentalists are worried that most are ending up in garbage dumps.
Mercury is probably best-known for its effects on the nervous system. The Mad Hatter in the classic children's book "Alice in Wonderland" was based on 19th-century hat makers who were continually exposed to the toxin.
Mercury can also damage the kidneys and liver, and in sufficient quantities can cause death.
U.S. regulators, manufacturers and environmentalists note that, because CFLs require less electricity than traditional incandescent bulbs, they reduce overall mercury in the atmosphere by cutting emissions from coal-fired power plants.
But some of the mercury emitted from landfills is in the form of vaporous methyl-mercury, which can get into the food chain more readily than inorganic elemental mercury released directly from a broken bulb or even coal-fired power plants, according to government scientist Steve Lindberg.
"Disposal of any mercury-contaminated material in landfills is absolutely alarming to me," said Lindberg, emeritus fellow of the U.S. Department of Energy's Oak Ridge National Laboratory.
The mercury content in the average CFL — now about 5 milligrams — would fit on the tip of a ballpoint pen, according to the U.S. Environmental Protection Agency, and manufacturers have committed to cap the amount in most CFLs to 5 milligrams or 6 milligrams per bulb.
The majority of Philips Lighting's bulbs contain less than 3 milligrams, and some have as little as 1.23 milligrams, said spokesman Steve Goldmacher.
To prevent mercury from getting into landfills, the EPA, CFL makers and various organizations advocate recycling.
Funny how complicated it all really is in the real world, isn't it? A lot of advocacy groups push single solutions to complex issues - and those single solutions are sometimes actually creating more but slightly different problems. Some of the different problems are actually worse than the ones the single issue solution initially addressed. For example: it is all very well to force the use of highly efficient light bulbs. Then you have to mandate recycling to keep these out of landfills. But that brings up a few little, teeny questions:
What happens when you break one of these inside your home? Will it be mandated next that hazmat teams have to decontaminate your home? Better yet: will you, personally, become legally responsible if the buyer of your home down the road finds that there is mercury contamination as a result of a light bulb breaking while you owned the house? These are not insignificant questions, folks.
