| dc.description.sponsorship | The production of electronic waste is increasing worldwide and the life span of some of the equipments is very short. This is a significant problem because some of the products including computer and mobile phones contain heavy metals and other chemicals which are hazardous and are consequently a threat to the environment and human health. The impact disposal may release toxic substances, viz. lead, cadmium, mercury, tin, copper, chromium and toxic gases. They may be reaching to the aquifer, soil or atmosphere in the level above than the permissible limit of the regulatory agencies. The first stage of the process for recovering metals and plastics from electrical/electronic waste involves dismantling obsolete equipments. Another method of recycling printed circuit boards (c. b.) that has been manually separated from electrical/electronic waste is smelting and an alternative method is mechanical separation widely used in the underdeveloped countries. Mechanically separated non-metal fraction of the printed c.b. is rich in hearting power and can be used in combustion purposes. Lead emitted by the Cathode Ray Tubes (CRTs) is toxic to plant and animal, long-term exposure can be harmful or even fetal. During metal recovery process from printed circuit boards, brominated dibenzo dioxin and furans are emitted which contaminate the environment. Heating of the two types of brominated flame retardant namely polybrominated dibenzo dioxin (PBDD) and tetrabromo bis phenol-A (TBBP-A), to temperature at 400-800°C in oven or tubes resulted in the production ofpolybrominated dibenzo furans (PBDFs). A comparative study of different methods used at national and international level for recovering metals and plastic from electronic waste is discussed in the review article. | en_US |
