Our
"plugged-in" world relies on an ever-growing and constantly
changing supply of electronic products. Electronic equipment currently
represents only 1 to 2 percent of the country's waste stream, but it
is quickly growing. The rapid introduction of new electronic products
shows no sign of abating, as better, smaller, and cheaper products replace
"older" models. Electronic products also can contain a variety
of toxic constituents. Cathode ray tubes, circuit boards, batteries,
and other electronic components often contain hazardous constituents
such as lead, mercury, and cadmium.
This
growing, changing product stream presents new challenges and responsibilities
in designing and managing electronic products to reduce their life-cycle
environmental impacts. By applying the principles of product stewardship,
electronic equipment can be made with fewer toxic constituents and designed
with upgradability, durability, and recyclability in mind, making these
product systems more sustainable.
