Objective Green Electronics = Green + Electronics The word ‘ green’ demonstrates the ‘ ecofriendly ’ character. “ Green Electronics emphasizes on elemination of harmful substances & the disposal of electronic wastes ; by applying ecofriendly techniques.” Green Electronics is simply E-waste Management.
Towards E-waste …… E-waste stands for Electronic wastes. HOW E-WASTES ARE GENERATED? HAZARDOUS SUBSTANCES IN E-WASTE, E-TOXIC COMPONENTS IN COMPUTERS , E-WASTE EXPORT ON INTERNATIONAL LEVEL,
E-waste Generation
Hazardous substances in e-waste Heavy metals ( As,Ba , Be, Cd, Cr, Pb ,Li, Hg ,Ni,Se,Zn ) Halogenated compounds PCB(Polychlorinated bi phenyles ) TBBA( Tetrabrominated - bis -phenol-A) PBB( Polybrominated di phenyl ethers) CFC( Chloro flouro carbon ) PVC(Poly vinyl chloride)

Disposal of e -waste Basically, three techniques are used for the disposal of E-waste materials: 1).Incineration 2). Landfillng 3).Recycling
incineration Incineration involves combustion of E-waste materials. Volume of E-waste materials can be Reduced upto 20-30% . Incineration is also called as “Thermal treatement ”. e. g. incinerators .
Land filling Simplest & highly applicable technique . Landfilling means “E-waste materials are burried (filled) inside the land”. Designing of landfills in a modern way is a complex phenomenon. e.g. modern landfills.

recycling Recycling refers to the widespread collection & reuse of E-waste. Collection of E-waste using dedicated bins, collection vehicals . Recycling of complex products( computer & electronic equipments) is slightly difficult in comparison to single type products(PVC).
