[GreenYes] Re: EPA mercury model
<> cfl.pdf

David - my source is the EPA. The above link takes you to a document they
created about the mercury content in CFLs. It is a great overview without
getting too technical. Some manufacturers have already reduced the amount of
mercury from the numbers given by the EPA. Manufacturers like TCP have
switched to a powder form of mercury that has shown to be less hazardous.
Improvements are being made but the media is slow to talk about it.

I have never used a techno trash can.but I have been saving electronics for
a while also. I will check it out. CFL recycle is more complex than other
products and there are very few sources.
<> and
<> list places to recycle. They will charge you
a fee to do it based on the number and weight of the CFLs. There should be
something in your area; however, recycling is not yet convenient. I have
started recycling drives in our area - hopefully others will do the same in
their areas.

So, in essence what you're saying with the numbers you give is that in the
lifecycle analysis of incandescents, they produce 10 mg of mercury and in a
similar analysis CFLs produce 6.4 mg. That's not been borne out at all in
the press coverage of this issue. Any way you can provide your source? This
is important. Thanks, Joy.

As an aside, has anyone done business with GreenDisk using their TechnoTrash
Cans? They have a $30 for $35 pounds or less deal and a $40 for up to 70
pounds deal. Go to

I'm curious because it seems to me that the atomistic approach to
electronics that tends to be the norm, misses out on a more holistic set of
solutions. As far as I know GreenDisk is set up to be able to handle
everything electronic. I have one CFL right now (more in a couple of years)
but I also have old pre1990 printers, VHS tapes, a couple of busted laptops,
assorted laptop batteries, obsolete cell phones, cords, mice, bum CDs &
DVDs, old cassettes, old floppy disks, dilapidated keyboards, etc. I'd just
as soon pay $40 to see the whole kit and kaboodle dealt with responsibily
than have it turn into an endless pile in my closet. As far as I know, they
don't take CFLs, but they sure should.

Here is a breakdown on Mercury emmissions vs. Mercury contained within the
CFL that may be of interest:

-The production/manufacture of 1 traditional incandescent light bulb emits
10 mg. of Mercury emissions into the air
-1 traditional incandescent contains 0 mgs of mercury within the bulb itself

-CFLs produce 6.4 total mgs of combined Mercury (airborne emissions and
solid mercury inside the CFL)
-The production/manufacture of 1 CFL emits 2.4 mg. of Mercury emissions into
the air (far less than a traditional light bulb)
-1 CFL contains 4.0 mg of Mercury (mixed with other chemicals) within the
glass tubing. This is about the size of the head of a ball point pen spread
across the inside of the bulb.

Airborne mercury is a far greater concern than powder or liquid mercury
contained in the bulb itself with the caveat that they are recycled
properly. I have seen dozens of pictures of fluorescents in the landfills
and it is disturbing.

Hi Matt ~

Yes, the EPA numbers do include all fluorescents. The model does show a
break down of fluorescents and non-fluorescents (some of which also contain

BTW, some CFLs have more mercury in them than the linear bulbs. All should
be recycled.

Again, I would be glad to send the model to anyone. There are a lot of
mercury products that should be diverted from landfills and incinerators and
I would encourage all recycling programs to help out in this effort.

John -

I'm way out of my league here, but wouldn't the EPA number (for mercury)
include all fluorescent lights (like the long white tube kind, that are
fairly ubiquitous) versus the smaller, individual fixture Compact
Fluorescent Lights (CFLs) which are not quite as mainstream, but are seen as
one quick thing an individual can do to reduce individual energy

Does EPA break out the source of the Hg (i.e., type of light, etc)?

According to the mercury flow model done for EPA, the release of mercury

All the coal burning power plants in the US emit about 45 metric tons of
mercury to the air.

So, fluorescents are not an insignificant source of mercury emissions to the

The ENERGY STAR program has pretty rigorous QA/QC in terms of lumen
maintenance and hours of use. If they don't perform, they don't get
certified. IF they don't get certified, Wal-Mart won't sell them. Also, the
EPACT set up certain hours of use requirmenets for CFL's - I think it is

Don't forget, as a source of anthropogenic Hg, this is a very small one.
