Transcript of "Ef fects of computers on enviournment"

  1. 1. Harmful Effects of Computers OnEnvironmentRishabh soodPresenter:-
  2. 2. Why THIS topic????TODAY:• 36 million PCs in INDIA only.• About 30 people per 1 PC ratio.• Geysers are used in winters andAir Conditioners in Summers BUT COMPUTERS 24*7 all over theworld.IN 10 YEARS:• 100 million PCs in INDIA• About 12:1 ratio per PC WE yet do not know that COMPUTERS (which we stick toeveryday) DO HARM OUR ENVIRONMENT. So there is a need for MASS AWARENESS about it.
  3. 3. What all Présentation Includes???• Need for this Presentation.• E-WASTE (Computer waste Being a part of E-waste).• Effects of computer on environment.• Disposal of computer waste.• W.E.E.E• NComputing (Green Computing)• What can we do to save our Environment fromComputers.• What about the companies which make theComputers.
  4. 4. « THE ‘ NEED’ ?? »The sale of computers is growing …….And that too EXPONENTIALLY^^^^
  5. 5. The Impact of So Many PCs on theEnvironmentGenerate 1.8 million metric tons of e-Waste.
  6. 6. The Impact of So Many PCs on theEnvironment(cont..) Emit 118 Million Metric tons of CO2 emissions/year
  7. 7. The Impact of So Many PCs on theEnvironment(cont..) Computer products often contain hazardous and toxicmaterials that pose environmental risks if they are landfill orincinerated. Computer monitor use cathode ray tubes (CRTs), which havemajor amounts of lead. Printed circuit boards contain primarily plastic andcopper, and most have small amounts of chromium, leadsolder, nickel, and zinc. In addition, many computers have batteries that often containnickel, cadmium, and other heavy metals.
  8. 8. • Computer generatedwaste Is a part ofE-waste..•E WASTE
  9. 9. INTRODUCTION• Electronic Waste pr “e-waste” is awaste consisting of any broken orunwantedelectrical or electronic appliance.• Term used to describe old, end oflife or discarded appliances usingelectricity and battery.• It is a point of concernconsidering that manycomponents of suchequipment areconsidered toxic and arenot biodegradable.
  10. 10. SOURCES OF E-WASTEThe table constitutes compositionof various electronics equipments.• 0-10% - Monitors and Televisions• 10-15% - Computers , Telephones,Radios, etc.• 15-20% - Refrigerators• 20-30% - Washing machines,Dryers, Coffee Machines, Irons etc.
  11. 11. TOXIC SUBSTANCESPRESENT IN E-WASTEThere are manyharmful materialsused in computersincludinglead, cadmium, mercuryand plastics.
  12. 12. Who gets the Thrash?• According to an estimateIndia generates nearly 2lakh tons of E-wasteannually.• And added to this another0.5 0.5-1 lakh ton/annuallydumped into the country asscrap.• The cities in Indiagenerating and receiving e-waste areAhmedabad, Bangalore, Bombay
  13. 13. THE CURRENT SCENARIO ININDIA E-WASTE PILING UP• 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 tonnes
  14. 14. Harmful Effects of Computeron Environment• MANUFACTURING• UTILISATION• DECOMPOSITION
  15. 15. Manufacturing Stage• Microchips are made out of Silicon Wafers that produceextravagant amount of pollution.• Producing wafers cost us 4,267 cubicfeet of bulk gases, 27 pounds ofchemicals, 29 cubic feet of hazardousgases and 9 pounds of hazardouswaste.• Manufacturing of a normal PC approx. 30000 mega joule inenergy are used.
  16. 16. Utilizing• As the demand for larger monitors and more memory chipsgrows due to developments in multimedia, so does the levelof toxins and fumes released into the environmentcontributing even more to the problem.• Pollution caused by computers has a large effect on society. Ithas effects on the environment due to paper consumption,energy consumption• Disease by computer
  17. 17. Decomposition• The more new computer models produced, the more oldmodels get thrown out.• Actually 90--92% of the computer components can be reusedbut it is rarely done.• E-waste cannot be dumped into the ground and has to bethrown out somewhere that is why it takes a lot of place tokeep the garbage.• Burning the whole lot causes harmful pollution to theenvironment . The major pollutant from this is CO2
  18. 18. PROBLEM• How to manage computer waste• How to dispose computer waste
  19. 19. The best ways to manage itare
  20. 20. Methods of Safe and Clean ElectronicWaste Disposal• Redesign of computer components• Consumer Education• Updated Sorting Methods• Samples taken of soil, air, and waterin areas surrounding disposal sites
  21. 21. WEEE• Waste Electrical and Electronic Equipment.• Came into force in 1st July 2007• Moto to dispose E-waste in echo friendlymanner
  22. 22. WEEE CATEGORIES OF EQUIPMENT• Household appliances—Ex-: Cooling appliances,Refrigerators, Washing machines etc.• IT Instruments—Ex-: Mini Computers, printers etc.• Electrical and electronic tools—Ex-: Drills, Solder etc.• Monitoring and control instruments—Ex-: Smoke detector,Heating regulators.
  23. 23. NCOMPUTINGMaximize your investment in PCs by sharing theirexcess power with many users for as little as $70each.Up to 11 users on a low-cost desktop Hundreds ofusers on a server.
  24. 24. How It NComputing VirtualDesktops Work?1) NComputing vSpace desktop virtualization software creates virtualindependent desktops inside one Windows or Linux PC.2) NComputing User eXtension Protocol (UXP) delivers an efficient,secure, multimedia interface.3) NComputing access devices are small, silent, energy-efficient,reliable, and veryinexpensive.
  25. 25. Greenest Computing on Earth• Cut Electricity 90%• – Only use 1 to 5 watts of electricity(compared to 110 watts or PCs)• – Radically cut electricity costs and carbonfootprint• – Lower heat generation means cooler workarea
  26. 26. • No Obsolescence• – Solid state device has 10 year life and nomoving parts to fail• – Only one PC to replace/upgrade and manyusers benefit• Reduce e-waste• – NComputing devices only weigh 100 grams(compared to 10 kg for PCs)
  27. 27. Energy Reduction• DisplayCRT monitors contains significant amounts of lead .LCD contains LEDs which consume less power and has better display• Video CardNo video card use a shared terminal, shared thin client, or desktop sharing softwareif display required.• Operating System SupportHibernate, sleep• Terminal ServerWhen using the system, users at a terminal connect to a centralserver; all of the actual computing is done on the server, but the enduser experiences the operating system on the terminal.These can be combined with thin clients, which use up to 1/8 theamount of energy of a normal workstation, resulting in a decrease ofenergy costs and consumption.
  28. 28. Strategy• Laptop instead of PCSaves up to 70 % of energy consumptions• Use a Ecofriendly search enginesome search engines like EcoSearch.org, donate aportion of their profit for environmental cause• Green-Rated EquipmentsUse equipment made of recycle components
  29. 29. • Product LongevityMany hazardous products are used inmanufacture therefore upgrading the pc is betteroption• Use plants near P.C.’sPlace plants especially cactus near P.C.’s whichcan absorb most of the radiation.
  30. 30. What can WE do???• First, do not throw away your old Computers!• If they are still working donate them so theycan be reused.• If they are no longer and you want to recyclethem in a responsible way…..……………………………
  31. 31. What can WE do???(cont…)• Visitwww.computertakeback.com• Website allows you to search forresponsible recycler in yourarea….• ….if there aren’t any it providesadvice on how to learn if themanufacturer of your productoffers responsible recyclingprograms• Some, like Apple’s TakeBackProgram allow consumers torecycle products.• Dell also will take back theirelectronics
  32. 32. « « ..PLEDGE.. » »• Whatever we have learnt we’llimplement it in our LIFE.• We’ll always try to search someways to make our environmentBETTER , BETTER and evenBETTER……
