Electronic Waste:
What happens to our electronic
equipment later?
Video showing e-waste in China.
What is electronic waste?
Televisions, Computer equipment,
Stereo equipment, VCR/DVD
players, Video equipment,
Telephones, Cell phones,
Wireless devices, Fax/Copy
machines, mp3 equipment,
video game consoles.
Why is it a concern?
• The amount of e-waste is increasing 2-3 times
faster than any other type of waste.
• E-waste contains many hazardous materials

Where does most of our e-waste
eventually go?
• E-waste is banned in most of Europe and the
U.S.
• Most of it is being shipped to developing
countries where poor residents (adults and
children) separate the materials in order to sell
back metals.
• Video in India.
• Much of our electronic equipment is not made
in the U.S. Working conditions elsewhere
provide little protection to the employees.
• Video in Mexico.
What happens with our e-waste?
• In 2002, the European Union began
requiring manufacturers to pay the entire
cost of recycling the electronic equipment
they produce.
• This is not required in the U.S. Only 6% of
electronic equipment in the U.S. is
recycled.
• Americans dispose of millions of tons of ewaste every year (eventually ending up in
foreign dumps or U.S. landfills).
What can we do with our e-waste?
• For electronic equipment that is still working and
less than 5 years old, donate this equipment!
• For older or non-working electronic equipment,
responsibly recycle this equipment. There are
certified recyclers in the U.S. Typically it costs
$20 - $50 to recycle electronic equipment.
• Support the Basel Convention – a treaty signed
by every developed country except for the U.S. –
This treaty regulates the movement of
hazardous waste across international borders.
The goal is to limit the dumping of hazardous
waste from wealthier countries into poorer
countries.
