Answers
Answer:
Electronic waste, popularly known as ‘e-waste’ can be defined as electronic equipment’s/products connects with power plug, batteries which have become obsolete due to: advancement in technology changes in fashion, style and status nearing the end of their useful life.
E-waste encompasses ever growing range of obsolete electronic devices such as computers, servers, main frames, monitors, TVs & display devices, telecommunication devices such as cellular phones & pagers, calculators, audio and video devices, printers, scanners, copiers and fax machines besides refrigerators, air conditioners, washing machines, and microwave ovens, e-waste also covers recording devices such as DVDs, CDs, floppies, tapes, printing cartridges, military electronic waste, automobile catalytic converters, electronic components such as chips, processors, mother boards, printed circuit boards, industrial electronics such as sensors, alarms, sirens, security devices, automobile electronic devices.
Electronic waste or e-waste is one of the rapidly growing environmental problems of the world. In India, the electronic waste management assumes greater significance not only due to the generation of our own waste but also dumping of e-waste particularly computer waste from the developed countries. With extensively using computers and electronic equipment’s and people dumping old electronic goods for new ones, the amount of E-Waste generated has been steadily increasing.
At present Bangalore alone generates about 8000 tonnes of computer waste annually and in the absence of proper disposal, they find their way to scrap dealers. E-Parisaraa, an eco-friendly recycling unit on the outskirts of Bangalore which is located in Dobaspet industrial area, about 45 Km north of Bangalore, makes full use of E-Waste.
The plant which is India’s first scientific c-waste recycling unit will reduce pollution, landfill waste and recover valuable metals, plastics & glass from waste in an eco-friendly manner. E-Parisaraa has developed a circuit to extend the life of tube lights. The circuit helps to extend the life of fluorescent tubes by more than 2000 hours. If the circuits are used, tube lights can work on lower voltages.
The initiative is to aim at reducing the accumulation of used and discarded electronic and electrical equipments. India as a developing country needs simpler, low cost technology keeping in view of maximum resource recovery in environmental friendly methodologies. E-Parisaraa, deals with practical aspect of e-waste processing as mentioned below by hand. Phosphor affects the display resolution and luminance of the images that is seen in the monitor.
Answer: Electronic waste causes a huge amount of environmental pollution which is not only detrimental to humans but animals.
Explanation: Electronic devices that are nearing the end of their useful lives, are out of date, or have been replaced are referred to as electronic garbage, or e-waste. Computers, monitors, televisions, stereos, copiers, printers, fax machines, smartphones, DVD players, cameras, batteries, and many more electronic gadgets are among the most popular ones. These used gadgets can be recycled, salvaged, resold, or utilised again. Computers and other electronics should not be disposed of because they contain harmful substances including lead, zinc, nickel, flame retardants, barium, and chromium. When electronic trash is placed in landfills, hazardous substances may leak into the groundwater and soil, posing a threat to not only human health but also the health of land and marine life.Lead may harm the central and peripheral neurological systems, as well as the human blood and kidneys, if it is discharged into the environment.
