SOURCES: SOURCES IT and telecom equipments Large household appliances Consumer and lightning equipments Electrical and electronic tools Toys ,leisure and sport equipment Medical devices IS IT HAZARDOUS WASTE?: IS IT HAZARDOUS WASTE? E-Waste contains several different substances and chemicals, many of which are toxic and are likely to create adverse impact on environment and health, if not handled properly. However, classification of E-waste as hazardous or otherwise shall depend upon the extent of presence of hazardous constituents in it.EFFECTS 1.effects on environment: EFFECTS 1.effects on environment Pollution of Ground-Water. Air Pollution. Acidification of soil E-Waste accounts for 40 percent of the lead and 75 percent of the heavy metals found in landfills.2.Effects on human health: 2.Effects on human health Damage to central and peripheral nervous systems, blood systems and kidney damage. Affects brain development of children. Chronic damage to the brain Respiratory and skin disorders due to bioaccumulation in fishes. Asthmatic bronchitis. DNA damage. Immune system damage. Lung Cancer .CURRENT SCENARIO IN INDIA: CURRENT SCENARIO IN INDIA E-WASTE PILING UP Mumbai at present tops the list Mumbai - 11, 017 tonnes Delhi - 9,730 tonnes Bangalore - 4,648 tonnes Chennai - 4,132 tonnes Kolkata - 4,025 tonnes Ahmedabad - 3,287 tonnes Hyderabad - 2,833 tonnes Pune - 2,584 tonnes Surat - 1,836 tonnesThe total e-waste in India has been estimated to be 1,46,180 tonnes per year : The total e-waste in India has been estimated to be 1,46,180 tonnes per yearE-WASTE MANAGEMENT: E-WASTE MANAGEMENT In industries management of e-waste should begin at the point of generation. Waste minimization in industries involves adopting: 1.Inventory management, 2. Production-process modification, 3. Volume reduction, 4. Recovery and reuse.COLLECTION OF E-WASTE: COLLECTION OF E-WASTE E-WASTE CAN BE COLLECTED IN MANY WAYS SUCH AS 1.ARANGING BINS IN POPULATED PLACES 2.ENCOURAGING THE EX-CHANGE OFFERS 3.GATHERING THE WASTE FROM STREETS AND MOVE THEM TO DUMP YARDSRECYCLING OF WASTE: RECYCLING OF WASTE Treatment Options Of E-Waste. 1.Land filling. 2.Incineration. • Technologies In India. 1.E-waste trade value chain. 2.Environmentally Sound E- wasteTreatmentTechnology 3.CRT treatment technology. Technology Currently Used in India. 1.Decontamination. 2.Dismantling. 3.Pulverization/ Hammering. 4.shredding 5.Density separation using waterAPPROACH AND METHODOLOGY STEPS solving e-waste problem: APPROACH AND METHODOLOGY STEPS solving e-waste problem Step 1: Identify the E-waste category item. Step 2: Identify the E-waste composition or determine it. Step 3: Identify possible hazardous content in E-waste. Step 4: Identify, whether the E-waste component is hazardous or the entire E- waste item is hazardous. PROCESS: PROCESS The process of recycling is as follows: 1.collection of waste. 2.safe storage. 3.manual dismantling & sorting(step1). 4.automated seperation (step 2). 5.material recovery(step3) 6.hazardous material sagregation & disposal.LEGISLATION: LEGISLATION INDIA The Ministry of Environment and Forests in India is currently drafting “WEEE" legislation. E-waste/ components, which are hazardous in nature need to be covered under the purview of –The Hazardous Waste (Management and handling) Rules 2003 –The Batteries (Management and Handling) Rules, 2001 –The Ozone Depleting Substances (Regulation and Control) Rules, 2000.
