Methods Of Safe And Clean Electronic Waste Disposal

  1. 1. Methods of Safe and Clean Electronic Waste Disposal<br />Presented by:<br />Daniel Werntz<br />
  2. 2. Background Information<br />Electronic waste in one of the fastest growing streams of waste in the world<br />Computers account for 50 million tons of waste annually<br />Current Disposal Methods<br />Incineration<br />Acid Baths<br />Landfills<br />
  3. 3. The state of things<br />Electronics contain over 1000 different materials, many of them toxic<br />In the US, end of life electronics end up in landfills or are exported to developing countries<br />Developing countries are the worlds dumping grounds for electronic waste<br />
  4. 4. Why is this a problem?<br />Landfill disposal allows heavy metals to leach into ground water<br />Incineration makes hazardous material airborne<br />Acid baths are dangerous and cause water and soil contamination<br />Exported materials are handled improperly<br />Most e-waste goes to China, India, and Africa<br />Workers are untrained and uneducated in safe handling of electronic waste<br />No environmental protection laws<br />
  5. 5. Environmental Impacts<br />Studies conducted in China discovered heavy contamination in e-waste recycling regions<br />Soil, air, water, and sediments all contained high levels of contamination<br />Trace metals (Lead, Zinc, Nickel, Copper, Mercury, and Cadmium)<br />Polychlorinated Biphenyls<br />Polycyclic Aromatic Hydrocarbons<br />Dioxins<br />
  6. 6. Methods<br />Redesign of computer components<br />Simplification of the deconstruction process<br />Consumer Education<br />Easy to access information about where to dispose of unwanted electronics<br />Updated Sorting Methods<br />Automated sorting processes<br />
  7. 7. Methods<br />Samples taken of soil, air, and water in areas surrounding disposal sites<br />Taken before the test is begun and once a week every week after the start<br />This will be considered a success if contamination levels are the same or lower than the initial samples<br />
  8. 8. Desired Results<br />The purposed methods aim to:<br />Reduce export of e-waste to developing countries<br />Reduce the release of hazardous materials during recycling and disposal<br />
