Electronic waste (e-waste) now makes up five percent of all
municipal solid waste worldwide, nearly the same amount as all plastic
packaging, but it is much more hazardous. Not only developed countries generate
e-waste; Asia discards an estimated 12 million
tons each year.
·
E-waste is now the fastest growing component of the municipal
solid waste stream because people are upgrading their mobile phones, computers,
televisions, audio equipment and printers more frequently than ever before.
Mobile phones and computers are causing the biggest problem because they are
replaced most often.

Interesting Facts:
- The average lifespan of computers in developed countries has dropped from six years in 1997 to just two years in 2005.
- Mobile phones have a lifecycle of less than two years in developed countries.
- 183 million computers were sold worldwide in 2004 - 11.6 percent more than in 2003.
- 674 million mobile phones were sold worldwide in 2004 - 30 percent more than in 2003.
- By 2010, there will be 716 million new computers in use. There will be 178 million new computer users in China, 80 million new users in India.

That makes an average 20 to 50 million metric tons of e-waste
are disposed worldwide every year.

Toxic 'e-waste' dumped in poor nations, says United Nations
Millions of tons of old electronic goods illegally
exported to developing countries, as people dump luxury items
John Vidal
The Observer, Saturday, December 14, 2013
Edited for use.
Millions of mobile phones, laptops, tablets, toys, digital cameras and
other electronic devices bought this Christmas are destined to create a flood
of dangerous "e-waste" that is being
dumped illegally in developing countries, the UN has warned.
The global volume of electronic waste is expected to grow by 33% in the
next four years, when it will weigh the equivalent of eight of the great
Egyptian pyramids, according to the UN's Step
initiative, which was set up to tackle the world's growing e-waste
crisis. Last year nearly 50m tons of e-waste was generated worldwide – or about
7kg for every person on the planet. These are electronic goods made up of
hundreds of different materials and containing toxic substances such as lead,
mercury, cadmium, arsenic and flame retardants.
Once in
landfill, these toxic materials seep out into the environment, contaminating
land, water and the air. In addition, devices are often dismantled in primitive
conditions. Those who work at these sites suffer frequent bouts of illness.
An
indication of the level of e-waste being shipped to the developing world was
revealed by Interpol last week. It said almost one in three containers leaving
the EU that were checked by its agents contained illegal e-waste. "The explosion is happening because
there's so much technical innovation. TVs, mobile phones and computers are all
being replaced more and more quickly. The lifetime of products is also
shortening."
Although it is legal to export discarded goods to poor countries if they
can be reused or refurbished, much is being sent to Africa or Asia
under false pretences, says Interpol. "Much is falsely classified as 'used
goods' although in reality it is non-functional. It is often diverted to the
black market and disguised as used goods to avoid the costs associated with
legitimate recycling," said a
spokesman. "A substantial proportion of e-waste exports go to countries
outside Europe, including west African
countries. Treatment in these countries usually occurs in the informal sector,
causing significant environmental pollution and health risks for local
populations," he said.
The
European Environment Agency, which estimates between 250,000 tons and 1.3m tons
of used electrical products are shipped out of the EU every year, mostly to
west Africa and Asia. "These goods may
subsequently be processed in dangerous and inefficient conditions, harming the
health of local people and damaging the environment," said a spokesman.
A new study by the Massachusetts Institute of
Technology suggests
that the US
discarded 258.2million computers, monitors, TVs and mobile phones in 2010, of
which only 66% was recycled. Nearly 120million mobile phones were collected,
most of which were shipped to Hong Kong, Latin America and the Caribbean. The shelf life of a mobile phone is now less
than two years, but the EU, US and Japanese governments say many hundreds of
millions are thrown away each year or are left in drawers. In the US, only 12million
mobile phones were collected for recycling in 2011 even though 120million were
bought. Meanwhile, newer phone models are racing on to the market leaving old
ones likely to end up in landfills.
The
failure to recycle is also leading to shortages of rare-earth minerals to make
future generations of electronic equipment.
