Every year industry develops a new technology & in the entire world the use of electronic products has grown substantially over the past two decades, changing the way & speed of communication. Rapid changes in technology, low initial cost & planned obsolescence have resulted in fast growing surplus of electronic waste around the globe. The world produces about 40 millions tones of waste from electronic devices known as E-Waste. Large quantity of unused electronic waste causes serious pollution problem, environmental & health hazards because it contains some very serious contaminants such as CRTs, PCB, Silicon, Carbon, Arsenic, Cadmium, Mercury etc. but the e-waste also contains many valuable, recoverable materials such as aluminum, copper, gold, silver, plastic& tin. In order to conserve natural resources & the energy needed to produce new electronic equipment can be refurbished, reused & recycled instead of being land filled by tacking out the harmful contain from it. As the earth is turning into giant garbage of e-waste its recycling is necessary. Recycling is the method of retrieving operable parts & ingredients from unusable electronic devices. [1]
Like that we can produce anything from the old one. Also the wires of the old circuit can be used for next one. So, from the whole condition given above, recycling of e-waste is very essential as it saves energy, expenses, reduce environmental pollution & less chances of health hazardous.
