Abstract

The wide application of electronic devices in modern life which aims to improve the life quality and facilitate the affairs, in particular, increase the rate of out of use e-devices day after day. By the end of the useful life of E-devices, exceptional methods should be considered for their expulsion because they include some specific materials and compounds. E-Waste is described as the dark side of modern digital age and caused many problems for environment. Hereunder, the most important included compounds and materials in E-Waste and its dangers for environment will be described. Then the most common methods for its ex pulsing are investigated along with their effects, and some suggestions are presented in order to improve the management of E-Waste in the final chapter, which emphasize the reduction of waste volume as the main solution, considered 2-5 % of urban disposal correct treating of E-Waste is too important.Computer monitors, and CRTs of old TVs contain four lb (1.81 Kg) Lead in average, and their expulsion should be performed, through special methods at the end of their useful life. In addition to Lead, these devise also contain Chromium, Cadmium, Mercury, Beryllium, Nickel, Zinc and flame retardants and in case of not being excluded or recycled in a right way, the existing toxic materials in E-devises would be dangerous. Increasing the duration of useful life of E-device, dedicating them to low-income individuals, and updating them can be followed by economic use of the costs and precious recourses. Besides the prevention of environment pollution, the right recycling of electronic equipment, which is out of use, can bring back costly materials into the cycle.This paper illustrates E-waste, its hazard and treatment method, then E-waste condition in Iran is investigated and finally recycling computer-as a major E-waste item, and its economic benefits in Iran will be discussed as a case study. At the worst case-if only 50 percent of end-of-life available computer in Iran could be recycled 75 million dollar will be gained in the case of recycling
