E-WASTE What is E-Waste? Electronic Waste Describes discarded electrical or electronic devices What’s the big deal? Recycling and disposal of e-waste may involve significant risk to workers and communities. Great care must be taken to avoid unsafe exposure in recycling operations and leaching of material such as heavy metals from landfills and incinerator ashes.

E-WASTE Who are the main exporters of E-Waste? North America Europe

E-WASTE Where does E-Waste end up? Many old electronic goods gather dust in storage

E-WASTE Where does E-Waste end up? Many old electronic goods gather dust in storage waiting to be reused, recycled or thrown away. Three quarters of the computers sold in the US are stockpiled in garages and closets. When thrown away, they end up in landfills or incinerators or are exported to Asia and Africa: Ghana Nigeria Pakistan India China

E-WASTE How did the trade evolve? Many countries did not have the capacity to deal with the quantity of e-waste they generated or with its hazardous nature. Began exporting the problem to developing countries where laws to protect workers and the environment are inadequate or not enforced. Cheaper to 'recycle' waste in developing countries. Scrap yards found they could extract valuable substances such as copper, iron, nickel and gold, during the recycling process.

E-WASTE Impact on the following. . . Landfills: Toxic chemicals in electronics products can leach into the land over time or are released into the atmosphere. Incineration: This releases heavy metals such as lead, cadmium and mercury into the air.

Mines & factories What risks are there to workers who make computer chips? 40% more miscarriages Blood/brain/kidney cancer
