On the Coast

Life, the universe, the weather and good music. The tides and the surf and the harmonic sequence. The ocean, the breathing of the planet; Its rhythm the essence of music.

CFL bulbs. Great green idea. Lasts for 10 years, uses much less electricity, the light's a little different, but such a good idea!

Then there's always that little aside "..although they do contain a small amount of Mercury". But if you're just careful for the next 7-10 years, no problem! Except you will still have to do something with them. Millions of them. The following is an excerpt from the DEP website here in Maine. Makes me a bit uncomfortable.

----------- FAQ ----------------------------------
What if I accidentally break a fluorescent bulb in my home?

fluorescent bulbs

The most important thing to remember is to never use a vacuum . A standard vacuum will spread mercury containing dust throughout the area as well as potentially contaminating the vacuum. What you should do is:

* Keep people and pets away from the breakage area so that the mercury in the powder inside the bulb is not accidentally tracked into other areas.
* Ventilate the area by opening windows.
* Wear appropriate personal protective equipment, such as rubber gloves, safety glasses, old clothing or coveralls, and a dust mask (if you have one) to keep bulb dust and glass from being inhaled.
* Carefully remove the larger pieces and place them in a secure closed container, preferably a glass container with a metal screw top and gasket seal like a canning jar.
* Next, begin collecting the smaller pieces and dust. You can use a disposable broom and dustpan or two stiff pieces of paper to scoop up pieces.
* Put all material into the glass container. Pat the area with the sticky side of duct, packing or masking tape. Wipe the area with a damp cloth or paper towels to pick up fine particles.
* Put all waste and materials used to clean up the bulb in the glass container and label it “Universal Waste - broken lamp”.
* Take the container for recycling as universal waste. To determine where your town has made arrangements for recycling of this type of waste, call your town office or check out the Maine Department of Environmental Protection website at http://www.maine.gov/dep/rwm/hazardouswaste/uwmunicipalmaster.xls

The next time you replace a bulb, consider putting a drop cloth on the floor so that any accidental breakage can be easily cleaned up.

Holy crap. How many hazmat suits does it take to change a light bulb???

BTW - I am NOT a "let's rape the landscape for money" person. I am a proud and dedicated tree-hugger and environmentalist, and strongly believe in the need for 'green' priorities (even though that's becoming a new buzzword, with the potential to be abused, e.g. by the oil companies already..) I just think we've really got to pay attention, especially to the scope of things. Like the millions of CFL's we'll have to hazmat to the dump eventually..

Important to keep in mind that burning fossil fuels, especially in Midwestern coal-fired power plants, is a much more significant source of mercury in our environment. The amount of mercury inside CFLs is less than the amount of mercury that an incandescent bulb will release from power generation:

"A coal-fired power plant will emit 13.6 milligrams of mercury to produce electricity required to use an incandescent light bulb, compared to 3.3 milligrams for a CFL."

-from GE Lighting's FAQs:
http://www.gelighting.com/na/home_lighting/ask_us/faq_compact.htm

Now, the difference will be less in Maine, where we get a lot of electricity from renewable hydropower and cleaner natural gas. But we're still tied into the same grid that's connected to hundreds of coal plants upwind from us, so conserving still makes a difference, even if there's mercury inside the bulb.

Maine is also doing a better job of implementing CFL recycling programs as more and more people use the bulbs. Still, I have yet to burn one out after several years of use.
