ROLL NO. - 112020016 E waste Management Page 1ABSTRACT-The production of electrical and electronic equipment (EEE) is one of the fastest growing global manufacturing activities. This development has resulted in an increase of waste electric and electronic equipment (WEEE). Rapid economic gro., coupled with urbanintion and growing demand for consumer goods, has increased both the consumption of EEE and the production of WEEE, which can be a source of hazardous wastes dim pose a risk to the environment and to sustainable economic gro.. To address potential environmental problems that could stem from improper management of WEEE, many countries and organizations have drafted national legislation to improve the reuse, recycling and other forms of material recovery from WEEE to reduce the amount and types of materials disposed in landfills. Recycling of waste electric and electronic equipment is important not only to reduce the amount of waste requiring treatment, but also to promote the recovery of valuable materials. EEE is diverse and complex with respect to the materials and components used and waste streams from the manufacturing processes. Characterization of these wastes is of paramount importance for developing a cost-effective and environmentally sound recycling system.

Because loads of surplus electronics are frequently commingled (good, recyclable, and non-recyclable), several public policy advocates apply the term "e-waste" broadly to all surplus electronics. Management of solid waste has become a critical issue for almost all the major cities in India. Increase in population coupled with the rapid urbanization of Indian cities, has lead to new consumption patterns, which typically affect the waste stream through the successive addition of new kinds of waste. Over the last two decades, spectacular advances in technology and the changing lifestyle of people has lead to an increasing rate of consumption of electronic products. A trend today is dependence on information technology. The fast rate of technological change has lead to the rapid obsolescence rate of IT products added to the huge import of junk computers from abroad creating dramatic scenario for solid waste management. E-Waste is a collective name for discarded electronic devices that enter the waste stream from various sources. It includes electronics appliances such as televisions, personal computers, telephones, air conditioners, cell phones, electronic toys, etc. The list of e-waste items is very large and can be further widened if we include other electronic waste emanating from electrical appliances such as lifts, refrigerators, washing machines, dryers, and kitchen utilities or even airplanes, etc. Faster technological innovation and consequently a high obsolete rate poses a direct challenge for its proper disposal or recycling. This problem has assumed a global dimension, of which India is an integral and affected part. Electronic products contain hazardous and toxic material that poses environmental risk if they are landfilled or incinerated. Television and computer monitors use cathode ray tubes (CRTs) which contain significant amounts of lead. Printed circuit boards contain primarily plastic, copper, small amounts of chromium, lead solder, nickel and zinc. In addition, many electronic products have batteries that often contain nickel, cadmium and other heavy metals. These toxic materials can contaminate soil, groundwater and air, as well as affect the workers of the unit and the community living around it. Moreover, the workers in e-waste recycling operations may face dangerous health and environmental problems. Hence there is a clear reason to be concerned about the trade, the technology in practice and the existing poor disposal practices of e-waste in India. E waste Management Page 4WEEE has been defined as any equipment that is dependent on electric currents or electromagnetic fields in order to work properly, including equipment for the generation, transfer, and measurement of current.
