Electronic Equipments in E-Waste How these become E-Waste? Generators of E-Waste Why E-Waste a problem? Constituents of E-Waste E-Waste Disposal E-Waste in INDIA E-Waste in CHINA WEEE Directive What should be done? Slide 3: Today's Electronic Gadgets , Tomorrow's Electronic Waste What is Electronic Waste? : It is the term used to describe old, end-of-life or discarded appliances using electricity and battery. What is Electronic Waste? Electronic Equipments : Electronic Equipments Computers Treadmills Laptops Telephone Air Conditioner Printers Drill Machines Irons Mobile Phones How these become E-Waste? : How these become E-Waste? Changes and Advancement in technology Changes in fashion, style, and status Changing configuration Attractive offers from manufacturers Small life of equipments Generators of E-Waste : Generators of E-Waste Small business and House hold. Large businesses, Institutions and Government offices. Equipment manufacturers. Some examples : Some examples Cell phone upgrades Digital TV Conversion Software upgrades Can't change the battery in your iPod Disposable printers Why E-Waste A Problem? : Why E-Waste A Problem? Composed of Hazardous Materials Products are quickly obsolete and discarded Electronic products are difficult to recycle Discarded electronics are managed badly Most e-waste goes to Landfills Most recyclers don’t recycle , they export Prison recycling : High Tech Chain Gang Constituents Of E-Waste : Constituents Of E-Waste Hazardous materials Valuable materials Slide 13: Valuable Materials Slide 14: Waste Hierarchy refers to the "3 R’s" reduce, reuse and recycle Its aim is to extract maximum benefits from products and to generate the minimum amount of waste. E-Waste Disposal : Methods Recycle Landfill Incineration Reuse E-Waste Disposal E-Waste Recycling : E-Waste Recycling Definition:- Recycling is defined as the assembling, developing, promoting, or buying of new products, which are prepared from waste materials. Steps in Recycling : Steps in Recycling Dismantling of E-Waste Removal of hazardous materials such as PCB, HG, removal of plastic etc. Strong acids are used to remove valuable metals such as gold, lead, copper etc. Methods for recycling : Methods for recycling Consumer recycling Donation Take back Exchange Corporate recycling Slide 19: Advantages Recycled materials can be used in developing new equipments Valuable Materials are retrieved Helps environment by avoiding pollution Land filling : Land filling Definition:- Land fill is also known as dump, is a site for the disposal of waste materials by burial and is the oldest form of waste treatment. Disadvantages : Disadvantages Metals like mercury, cadmium, lead leaches into the soil and ground water making them polluted Requires large amount of space It is not a environmentally sound treatment Incineration : Incineration It is a controlled and complete combustion process, in which the waste material is burned in specially designed incinerators at a high temperature (900-1000oC). Definition:- Incinerator Slide 23: Advantages Disadvantages Reduction of waste volume Utilization of energy of combustible substances hazardous substances are converted into less hazardous substances Emission of harmful gases and residues Emission of cadmium and mercury Re-Use : Re-Use Definition:- It constitutes direct use or use after slight modifications to the original functioning equipment. Advantages : Advantages Electronic equipments like computers, cell phones etc. can be re-used. This method also reduces the volume of e-waste generation. no wastage of time and money E-Waste in INDIA : E-Waste in INDIA over 2 million e-waste is generated every year Harmful techniques like burning wires are common practice in the informal recycling sectors in big cities in India. Slide 27: Manual Dismantling Recycle Steps in INDIA Refining and conditioning Solid waste is deposited in a municipal landfill. Slide 28: E-Waste in CHINA In 2004, China discarded 4 million refrigerators 5 million TV sets 5 million washing machines China is receiving 90% e-waste from other countries. Slide 29: WEEE Directive Waste Electrical and Electronic Equipment Directive WEEE Symbol Slide 30: introduced in January 2007. aims to reduce the amount of electrical and electronic equipment being produced to encourage everyone to reuse, recycle and recover it. WEEE Directive WEEE Symbol WEEE Categories : WEEE Categories Large household appliances Lighting Equipment Electric and Electronic Tools Toys, sports Equipment IT and telecommunications equipment Office, Information & Communication Equipment Entertainment & Consumer Electronics Medical devices Did you know? : Did you know? The average lifespan of computers has dropped from 6 years in 1997 to just 2 years in 2005. Mobile phones have a lifecycle of less than two years in developed countries. 183 million computers were sold worldwide in 2004 - 11.6 percent more than in 2003. Slide 33: 674 million mobile phones were sold worldwide in 2004 - 30 percent more than in 2003. By 2010, there will be 716 million new computers in use. There will be 178 million new computer users in China, 80 million new users in India. What should be done? : What should be done? Proper laws and policies should be made Awareness among consumers and manufacturers Recycling should be preferred Products should be made recyclable Make usage of recycled products do not throw away old equipments Slide 35: ANY QUERIES ?.... Slide 36: THANK YOU.... You do not have the permission to view this presentation. In order to view it, please contact the author of the presentation.
