WHY ARE USED
ELECTRONICS A CONCERN?
"Besides taking up space in empty
cubicles and storerooms, end-of-life electronics pose several issues
regarding proper disposal and potential environmental consequences.
Discarded Electronics:
-
Represent
a rapidly growing waste stream. Technological advances are rapidly rendering
formerly cutting-edge electronics obsolete. An estimated 20 million personal computers became
obsolete in 1998. Most of these are in storage. Of
the remainder, the bulk were disposed of; probably fewer than
6 percent were recycled. Currently the useful life of a
computer is only 3 to 5 years and shrinking. In 2005, more
than 63 million personal computers are projected to be retired
according to a recent study by the National Safety Council.
-
Waste valuable
resources. Electronic
products are made of valuable resources, including precious
and other metals, engineered plastics, glass, and other materials,
all of which require energy to source and manufacture. Many
electronic products also contain parts that could be profitably
refurbished and reused with little effort. When we throw away
old electronic equipment, we're throwing away these resources
and generating additional pollution associated with the need
to access virgin materials and manufacture new products.
-
Contain hazardous
or toxic substance. Some
electronic products (notably those with cathode ray tubes or
CRTs, circuit boards, batteries, and mercury switches) contain
hazardous or toxic materials such as lead, mercury, cadmium,
chromium, and some types of flame retardants, and do so in amounts
that may cause them to test hazardous under federal law. In
particular, the glass screens, or CRTs in computer monitors and
televisions can contain as much as 27 percent lead. Some
estimates that since many batteries (such as car batteries) have
started to be removed from waste, electronic products represent
the largest remaining contributor of heavy metals to the solid
waste stream. There is concern, particularly at the state
and local levels, that products containing these constituents
might pose some environmental risks if they are not properly
managed at end-of-life."
