  3. Recycling involves manual participation and hence workers are exposed to harmful and toxic waste substances present in e-wastes.
  4. E-wastes are generally destroyed by incineration (burning in presence of oxygen) or through landfills in which the e-wastes are dumped in a trench or depression after compaction and covered with dirt everyday.
