[GreenYes] Re: EPA mercury model


So, in essence what you¹re 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. That¹s 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 http://www.Greendisk.org

I¹m 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. I¹d 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
don¹t take CFLs, but they sure should.
