Introduction: Today the world is changed, Now using electronic gadgets youth feeling more advance, Businessmen become more capable of doing business, and students in education now system is completely changed. Now education is not restricted in only class room teaching. Using computer, DLP projector, Audio,video system, Computer broad band system we can share education outside of the class room, BISAG and NME-ICT are already implementing these practices. Now using modern devices expert teacher sitting at one place shares his lecture at various places and lot many students can get benefits of his lectures, and his knowledge. Now every computer or electronic component has fixed life span. After completion of the life of electronic components, it becomes obsolete or unwanted or not for the future use. This may create the root cause for generating e waste in education systems.
Electronic waste or e-waste is, obsolete, broken, or unwanted electronic equipment-computers, laptops, TVs, DVD players, mobile phones, mp3 players etc.. E-waste is produced when the electronic products from our homes, schools, government offices and businesses eventually need to be discarded. While there is no generally accepted definition of e-waste, in most cases, e-waste comprises of relatively expensive and essentially durable products used for data processing, telecommunications or entertainment in private households and businesses. Public perception of e-waste is often restricted to a narrower sense, comprising mainly of end-of-life information- & telecommunication equipment and consumer electronics. However, technically, electronic waste is only a subset of WEEE (Waste Electrical and Electronic Equipment). According to the OECD any appliance using an electric power supply that has reached its end-of-life would come under WEEE
Environmental Impact of E WASTE : Generating e waste from education institutes will seriously effect social, environmental and health relevance's. If we dump it carelessly it will occupy useless space and if we sell out to waste dealers they will try to earn money by extracting precious metals but they are not aware of the seriousness of environmental pollution. Plastic non degradable materials are harmful for farmland. This will directly affect human beings. Mireike Buth had referred in his paper “The environmental impact of e waste”, the hazards of chemical found in e waste in which he mentioned about the electronic components and its chemical properties It is very risky for human’s health.
SubstanceOccurrence in e-waste Environmental and health relevance HELOGENATED COMPOUNDS PCB (Polychlorinated biphenyls Condensers, transformers Cause cancer, effects on the immune system, reproductive system, nervous system, endocrine system and other health effects,Persistent and bio-accumulative. TBBA (tetrabromo-bisphenol-A) PBB (polybrominated biphenyls) PBDE (polybrominated diphenyl ethers) Fire retardants for plastics (thermoplastic components, cable insulation). TBBA is presently the most widely used flame retardant in printed wiring boards and covers for components. Can cause long-term period injuries to health. Acutely poisonous when burned. Chlorofluorocarbon (CFC) Cooling unit, insulation foam. Combustion of halogenated substances. May cause toxic emissions. PVC (polyvinyl chloride)Cable insulation High temperature processing of cables. May release chlorine, which is converted to dioxins and furans.
HEAVY METALS AND OTHER METALS Arsenic Small quantities in the form of gallium arsenide within light emitting diodes Acutely poisonous and on a long-term perspective injurious to health. BariumGetters in CRT May develop explosive gases (hydrogen) if wetted Beryllium Power supply boxes which contain silicon controlled rectifiers, beam line components Harmful if inhaled. Cadmium Printer inks, toners, fluorescent layer (CRT screens) Rechargeable NiCd-batteries, Photocopying machines. Acutely poisonous and injurious to health on a long term perspective. Chromium VIData tapes, floppy-disksAcutely poisonous and injurious to health on a long term perspective causes allergic reactions
Lead CRT screens, batteries, printed wiring boards Causes damage to the nervous system, circulatory system, kidneys. Causes learning disabilities. LithiumLi- batteries May develop explosive gases (Hydrogen) if wetted. Mercury Fluorescent lamps that provide backlighting in LCDs, some alkaline batteries and mercury wetted switches Acutely poisonous and injurious to health on a long term perspective Nickel Rechargeable Ni Cd-batteries, NiMH-batteries, electron gun May cause allergic reactions. Rare earth elementsFluorescent layer (CRT- screen)Irritates skin and eyes/ Selenium Older photocopying-machines (photo drums) High levels may cause adverse health effects Zinc sulphide Interiors of CRT screens, mixed with rare earth metals Toxic when inhaled Gallium arsenideLight-emitting diode(LED)Injurious to health.
Fight against problems of e waste A lot of people dispose off electronics before they reach the end of their useful life. You can help reduce this waste by giving away the products that you don ’ t want to, someone, who does. Taking the time to donate your working electronics to organizations such as The Arc, Goodwill, or the Salvation Army not only prevents waste but also helps these organizations accomplish their goals. Many churches, community groups, and schools also accept donations of functional computers and computer equipments. Many electronic products require and many consumers prefer to use rechargeable batteries. Rechargeable batteries prevent waste and can be easily and conveniently recycled (see below). If you are using disposable batteries, however, make sure you buy those made without toxic heavy metals. The packaging and the batteries themselves will have labels indicating that they do not contain mercury or other heavy metals; many of these environment friendly batteries have a green stripe around them. Disposable alkaline batteries that do not contain heavy metals can be safely disposed off in your household garbage. Computer recycling or electronic recycling is the method of retrieving operable parts and ingredients from unusable electronic devices. Recycling also bears the connotation of renovating old PCs by substituting old, outdated components with new ones.
How Computer manufacturer companies dealing with e waste. E waste is global phenomenon and it is computer manufacturer company’s basic duty to give the solution regarding e waste problems. Many companies are supporting solutions for this e waste problem. Wipro company is also dealing with e waste. They are taking following actions to deal with e waste problems  Wipro will collect the discarded systems from customers on behalf of the recycling agency. Provide the discarded computers to vendors certified by Pollution control board to recycle the parts. Ensure collection and transport of systems from customer to final waste recycling point. This support is limited to recycling of e-waste related to Wipro products being retired by the customer. Monitor the recycling of e-wastes by agency according to guidelines given by the relevant pollution control boards. Wipro will submit Form 9 and other documents required by Pollution Control Board to ensure compliance to standards set by Pollution Control Board. Wipro will collect documentary proof that these items have been recycled in a safe manner by the vendor as recommended by Pollution control board.
Customer contacts any one of 17 Wipro contact centers or delivers the e-waste to one of the 17 locations. Wipro acknowledges the receipt of e-waste to customer. Wipro ensures delivery of e-waste to disposal agencies certified by pollution control board. Wipro monitors the disposal of e-waste by disposal agency (in eco friendly way) and shares the proof of disposal with customer. Conclusions: Information Technology plays key role in nations development. Computer education is becoming base for the nation’s development. In India we are second largest populated country, so as per brainis concerned, we don’t have problem. Only thing lacking is effectively teaching Information Technology to them. With use of modern devices internet, laptop, computers, DLP projectors, audio video systems we can reach to those students who really want to study but they don’t have facilities. Though E waste is problem to this kind of education system but if we tackle e waste problem intelligently there is absolutely no problem in computer education and we can give message to all new students regarding e waste.
