Electronic waste or e-waste describes discarded or disposed electrical or electronic devices. Used electronics which are destined for reuse, resale, salvage, recycling, or disposal are also considered e-waste. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution. Electronic Waste (e-Waste) comprises of waste electronic/electrical goods which are not fit for their originally intended use. These . include items such as computers, c r phones, stereos, refrigerators, air conditioners, other consumer durables, etc.
E-waste is one of the fastest growing waste streams in the world. In developed countries it, on an average, equals 1% of the total solid waste. The increasing "market penetration" in developing countries, "replacement market" in developed countries and "high obsolescence rate", make e-waste one of the fastest waste streams. It includes items such as televisions (TV), computers, Liquid Crystal Display (LCD), plasma panels, printing-scanning devices, mobile phones as well as a wide range of household, medical and industrial equipments which are simply discarded as new technologies become available.
At present, Indians use about 14 million PCs 16 million mobile phones and 80 million televisions. So, there is a pressing need to address e-waste management particularly in developing countries like ours.
WHAT IS WASTE MANAGEMENT? . Any substance that is discarded is known as waste. It is a valuable raw material located at a wrong place Many of the wastes, at present used in uneconomic manner or left completely unutilised, are causing great hazards to human environment. It can be converted into useful product by making use of appropriate processing technology These wastes are of various types and can be categorized as hazardous and nonhazardous.
. These can be further subdivided into municipal wastes, electronic wastes, bio medical wastes and Industrial waste. . Certain chemicals if released untreated, e.g cyanides, mercury, and polychlorinated biphenyls are highly toxic and exposure to these can lead to disease or death.
INTRODUCTION Rapid urbanisation and heavy uses of electronic gadgets during the last two decades has led to generation of a huge amount of electronic wastes resulting in soil, water and environmental pollutions. Thus pollution control and environmental safety has become the greatest concern of environmental scientists and activists worldwide.
. Because these wastes are not biodegradable, gradual deposition of these e-wastes leads to accumulation of various toxic metals like lead (Pb), cadmium (Cd) etc. and contaminates the soil and the ground water. Ground water contamination in turn, affects the plant animal and the living system as a whole causing severe health hazards and disorders. Therefore, proper management of these e wastes has become a Ultimate demand of the time.
