The
Problem of E-waste
Discarded
computers and other consumer electronics (so called e-waste)
are the fastest growing portion of our waste stream. There
are hundreds of millions of old computers and TV's "out
there," no longer being used, ready for disposal.
But
these products are full of toxic materials, like lead, mercury,
beryllium, and other chemicals which are extremely dangerous
to humans. Therefore we need to keep them out of our landfills
or incinerators, to keep these harmful chemicals from leaching
into our groundwater or polluting our air.

What
is E-waste?
When
electronic products become obsolete and are ready for disposal,
they are known as electronic waste, or e-waste. This includes
a wide range of products, including:
TVs - CRT (Cathode Ray Tube) style, Flat panel, plasma, LCD
Monitors - CRT style and Flat panels
CPUs (Desktop computers, workstations, servers)
Laptops
Computer peripherals: keyboard, mouse, printers, scanners
Television peripherals: DVD, VCRs, Receivers
Personal electronics: PDAs, Music players (iPods, MP3s, etc)
Cell phones and wireless devices
Audio and stereo equipment

How
big is the E-waste problem?
The
National Safety Council estimates that there are 300 to 500
million obsolete computers in the US, ready for disposal .
Likewise, hundreds of millions of televisions that have been
sold over the past 50 years have become obsolete. Discarded
computers and other consumer electronics (so called e-waste)
are the fastest growing portion of our waste stream - growing
almost 3 times faster than our overall municipal waste stream.
One hundred thirty million cell phones are retired each year.
The
problem is getting worse
Rapid
advances in technology mean that electronic products are becoming
obsolete more quickly. This, coupled with explosive sales
in consumer electronics, means that more products are being
disposed of, finding their way into landfills and incinerators.
To make matters worse, the FCC mandated transition to digital
television (HDTV) will only speed up the pace, as consumers
will soon be dumping large numbers of old TVs that can't receive
the new digital-only signals.
Some
statistics:
57 million televisions and computers are sold annually to
households and businesses in the United States.
Buyers of new TVs and computers often don't discard older
models when buying newer versions of the same products. Approximately
20 to 24 million computers and televisions are added to storage
each year.

Electronic
waste is toxic waste
Over 1,000 materials, including chlorinated solvents, brominated
flame retardants, PVC, heavy metals, plastics and gases, are
used to make electronic products and their components-semiconductor
chips, circuit boards, and disk drives. A CRT monitor can
contains between four and eight pounds of lead alone. Big
screen TVs contain even more than that. About 40% of the heavy
metals, including lead, mercury and cadmium, in landfills
come from electronic equipment discards.
What
are the health risks?
|
| Lead:
|
The
health effects of lead are well known; lead exposure causes
brain damage in children and has already been banned from
many consumer products. |
| Mercury: |
Mercury
is toxic in very low doses, and causes brain and kidney
damage. It can be passed on through breast milk. Mercury
is so toxic that even one drop deposited annually from
the atmosphere into a 20-acre lake is enough to make the
fish in that lake unsafe to eat. |
| Cadmium:
|
Cadmium
accumulates in the human body and poisons the kidneys. |
| BFRs:
|
Brominated
flame retardants (BFRs) may seriously affect hormonal
functions critical for normal development. A recent study
of dust on computers in workplaces and homes found BFRs
in every sample taken. One group of BFRs, PBDEs, has been
found in alarming rates in the breast milk of women in
Sweden and the U.S.
