Electronic Waste Management - Clean to Green
e-Waste What is E-waste? 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, cellular phones, stereos, refrigerators, air conditioners, other consumer durables, etc. Is e-Waste Hazardous? E-waste is not hazardous waste per-se. However, the hazardous constituents present in the e-waste render it hazardous when such wastes are dismantled and processed, since it is only at this stage that they pose hazard to health and environment. 2 Toxic constituents in e-waste COMPONENTS CONSTITUENTS Printed circuit boards Lead & cadmium Cathode ray tubes (CRTs) Lead oxide & Cadmium Switches & flat screen monitors Mercury Computer batteries Cadmium Capacitors and transformers Poly Chlorinated Bi-phenyls (PCB) Printed circuit boards, plastic Brominated Flame Retardant casings cable Cable insulation/coating Poly Vinyl Chloride (PVC) 3 Growing EEE Industry in India Information and telecom fastest growing industry verticals PC sales crossed 7.3 million units in 2007-08 growing 16%; installed base of over 25 million units Consumer electronics market growing at 13-15% annually ; 120 million installed base of TVS Cellular subscriber up by 96.86% over last year; Indtalled base to cross 300 million by 2010 4 Recycling scenario in India E-waste recycling is presently concentrated in the informal (unorganized) sector No organized collection system prevails Operations are mostly illegal Processes are highly polluting Recycling operations engage in: dismantling sale of dismantled parts valuable resource recovery export of processed waste for precious metal recovery …expected to rapidly change with formal recyclers setting operations 5 Concerns: Informal Recycling High-risk backyard operation Non- efficient and Non- environmentally sound technologies Occupational and environmental hazards Loss of resources due to inefficient processes Impacts vulnerable social groups- Women, children and mmigrant labourers 6 Thank you! 7
