E- Waste Management :

E- Waste Management S. vidhya

Objectives :

Objectives What is E- Waste ? Toxic constituents in E-Waste Health and Environmental Implications of E-waste Responsibilities of govt., industries and citizens Goals Conclusion

E-Waste :

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

E-Waste-cont…..:

E-waste is not hazardous 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. E-Waste-cont…..

Toxic constituents in e-waste:

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)

Health and Environmental Implications of E-waste:

Electronic and Electrical Equipment are composed of an enormous amount of components. Majority of these components contain toxic substances that have adverse impacts on human health and the environment if not handled properly. Disposal of E-wastes is an unembellished problem faced by many regions across the globe. Electronic wastes that are land filled produces contaminated leachates which eventually pollute the groundwater. Health and Environmental Implications of E-waste

Health and Environmental Implications of E-waste:

Health and Environmental Implications of E-waste

Health and Environmental Implications of E-waste:

Acids and sludge obtained from melting computer chips , if disposed on the ground causes acidification of soil. The most dangerous form of burning E-waste is the open-air burning of plastics in order to recover copper and other metals. The toxic fall-out from open air burning affects the local environment and broader global air currents, depositing highly toxic byproducts in many places throughout the world. ineration of E-waste possesses another threat. It can emit toxic fumes and gases, thereby Polluting the surrounding air. Health and Environmental Implications of E-waste

Health and Environmental Implications of E-waste:

Responsibilities of the Government :

Government should set up regulatory agencies in each district. The agency concerned should Collect basic information on the materials from manufacturers, processors and importers and to maintain an inventory of these materials. The information should include toxicity and potential harmful effects. Identify potentially harmful substances and require the industry to test them for adverse health and environmental effects. Control risks from manufacture, processing, distribution, use and disposal of electronic wastes. Encourage beneficial reuse of "e-waste" and encouraging business activities that use waste". Set up programs so as to promote recycling among citizens and businesses. Educate e-waste generators on reuse/recycling options . Responsibilities of the Government

Responsibilities and role of Industries :

Responsibilities and role of Industries Companies can adopt their own policies while handling e-wastes. Some are given below: Use label materials to assist in recycling (particularly plastics). Standardize components for easy disassembly. Re-evaluate 'cheap products' use, make product cycle 'cheap' and so that it has no inherent value that would encourage a recycling infrastructure. Create computer components and peripherals of biodegradable materials. Utilize technology sharing particularly for manufacturing and de manufacturing. Look at green packaging options.

Responsibilities of the Citizen :

Waste prevention is perhaps more preferred to any other waste management option including recycling. While buying electronic products opt for those that: Are made with fewer toxic constituents Use recycled content Are energy efficient Are designed for easy upgrading or disassembly Utilize minimal packaging Offer leasing or take back options Responsibilities of the Citizen

GOALS Policy level initiatives in India :

The Hazardous Wastes (Management and Handling) Amendment Rules, 2003 Guidelines for Environmentally Sound Management of E-waste, 2008 - Ministry of Environment and Forest and Central Pollution Control Board . The e-waste (Management and Handling) Rules, 2011 – These rules are meant to be applied to every producer, consumer or bulk consumer involved in manufacturing, sale purchase and processing of electrical and electronic equipment, collection centers, dismantlers and recyclers of e-waste. Responsibilities of producers, collection centers, consumers, dismantlers, recyclers etc. are defined and incorporated in these rules. GOALS Policy level initiatives in India

Conclusion :

There are only two authorized small E-waste dismantling facilities functioning in Chennai and Bangalore . The lack of public awareness regarding the disposal of electronic goods and inadequacy of policies to handle the issues related to E-waste enhance the problem in India. most of the cases, the bulk of E-waste remains unattended in households and public offices. Proper implementation of the “e-waste (Management and Handling) Rules, 2011” is exceedingly essential to address the ever-growing pile of E-waste in the country. Conclusion
