  • My personal experience with research paper writing services was highly positive. I sent a request to ⇒ www.WritePaper.info ⇐ and found a writer within a few minutes. Because I had to move house and I literally didn’t have any time to sit on a computer for many hours every evening. Thankfully, the writer I chose followed my instructions to the letter. I know we can all write essays ourselves. For those in the same situation I was in, I recommend ⇒ www.WritePaper.info ⇐.

  • I saved my research paper to the last minute. I was up very late at night panicking. My girlfriend suggested using a paper writing service. So, I did exactly that. They wrote a research paper for me at my set deadline. My writer followed the directions well. I know I could have done it myself, but in a situation like mine, I highly recommend these guys HelpWriting.net.

E waste management

  1. 1. on Strategy of E- Waste Management By Prayakarrao Sukanya
  2. 2. IntroductionSolid Waste Municipal waste Electronic waste Biomedical waste Industrial waste 2
  3. 3. E-Waste?? E-Waste: Waste of electronics / electrical goods that have reached their end of life Electronic products often contain hazardous and toxic materials and should not be dumped with other wastes. Along with China, India is largest importer of E-waste from developed countries like US, UK and Japan. In India 90% of mobile equipment are imported. The rate of e-waste generation is increasing by 10% every year. 3 0.8 million ton is contributed by India 40 Million ton E-waste produced globally
  4. 4. • Mobile phones • Telephones • Telephone exchanges Wireless Equipment cables and related scrap material • PC andTV Telecommunication Waste: • Switches • Relays • Connectors and related Scrap Material. Electrical Waste: • Electronic – metal waste • Printed Circuit Boards • E – Equipment and Machinery • IC • Sockets Connectors. ElectronicWaste: • PVC • Pre Insulated Copper and Aluminum Cable waste. CableWaste: 4

  6. 6. Facts and Figures 6000 mobile phones gives 3.5 kg Silver 340 gm of Gold 140 gm of Palladium 130 gm of Copper 6 1 Metric Ton of Electronic scrap contains more gold than 17 Ton of Gold from gold ore 1 PC 1.5 tons of water 48 pound of chemicals 539 pound of fossil fuels
  7. 7. Issue and Challenges Leaching of heavy metals from Landfills and Incinerators Exposure to workers & communities Unawareness (brand new items are also kept in waste) Less reuse Collection system Legal framework 7/5/2013 7
  8. 8. Reusing and recycling • Increase life span of product Landfills • Leaching problem (70% of Heavy metals in landfills are because of E-waste) Incineration • Fumes of Heavy metals released in atmosphere • Municipal incinerators are giving dioxins Ways of Treating E- Waste 8
  9. 9. 9 Receipt of E- Waste Sorting / Processing Repairing Upgrading Testing Refurbishing Dismantaling Component Recovery Captive Use Packing Sale Residual Disposal Scarp Environmentally- friendly disposal Recovery of Precious Material Flow Sheet of Recyclers or Recycling Units
  10. 10. Recycling scenario Takes useful COMPONENTS. Ferrous metals sold to metal dealers. Precious metals are recovered in a very dangerous and hazardous manner Rest goes to land filling / water filling- disturbs ecological equilibrium 10
  11. 11. Recycling of CRT workers manually dismantle most electronic equipment and sort out valuable commodities that are sold to various recyclers. CRTs ready to be "crushed" for recycling. 11
  12. 12. The CRT crusher is completely self-contained in a transportable shipping container. Crushed CRT glass, coated with lead, ready for processing by a lead smelter. 12
  13. 13. Other components from electronics are separated and sold as commodities to various recyclers. 13
  14. 14. How to Dispose E-waste Donate working older equipment to schools colleges or government entities in need. If PC are out of order then return it to the manufacturers. (HCL andWipro in India has best take back service) Send waste goods to authorised recycling facility for proper disposal. 14
  15. 15. Probable Solutions Need for stringent health standards and environmental protection laws in India, Extended producer responsibility, Import of waste under license, Producer-public-government cooperation, Awareness program, following safer and efficient methods Choosing safer technology and cleaner substitute, Monitoring of compliance rules, Reduction of waste at source, Investment opportunity in waste management sector and Recognition to the unorganised sector in India. 15
