E-waste generally consists of obsolete devices such as DVDs, CDs, floppies, tapes and electronic components including chips, processors, mother boards, printed circuit boards and industrial electronics. E-waste contains many hazardous substances like heavy metals, PVC plastics, brominated flame retardants.When disposed off in a landfill, it becomes a conglomeration of plastic and steel casings, circuit boards, glass tubes, wires, resistors, capacitors, fluorescent tubes, and other assorted parts and materials. It is both valuable as a source of secondary raw material, and toxic if treated and discarded improperly. he USA discards 30 million computers each year and 100 million phones are disposed of in Europe each year. The Environmental Protection Agency estimates that only 15-20% of e-waste is recycled, the rest of these electronics go directly into landfills and incinerators.India's rapidly growing economy generates more than 500,000 tons of electronic waste every year, a number expected to reach 1 million tons by 2012. The obsolete computer and cellphone parts are dismantled, refurbished and recycled manually by hundreds of thousands of unorganized villagers across the country.
