9. E-waste: a business platform
E-waste is becoming a source of income for the industries and
opens the doors for the new jobs also. In India, Bangalore city is
generating 18,000 metric tonnes of e-waste per year, and thousands of tonnes landed illegally per year. Because of different
metals like gold, silver, platinum, copper, aluminum, and rare
earth metals present in the e-waste are quite enough to reuse and
these are very costly providing new business opportunities. Some
material of e-waste has a capacity for reuse like the different
capacitor, circuit board, and plastic. If we control the toxic emission this can be incinerated for energy [40]. The plastic content of
electronic appliances bodies serves a good raw material for the
pyrolysis. Thermochemical treatment of such wastes is attracting
the scientists' interest, since it provides efficient energy and
material recycling without cumbering the environment. Pyrolysis
of plastics can be used to dispose the waste and to recover synthetic fuel. Pyrolysis oil recovered from this process can be used as
diesel generator fuel for burners [41]. The Plastic waste from WEEE
also serves as a raw material for hydrogen production through
two-stage reaction system of pyrolysis–gasification [42]. In
another research, a Liquid Crystal coated Polaroid Glass Electrode
(LCPGE) material collected from disposed liquid–crystal display
(LCD) computer monitor as electrodes in microbial fuel cell (MFC)
for electricity production [43]. Further research on efficient technology and reduction in toxic chemicals and treatment of these
toxic chemicals is required so that a cost efficient and eco-friendly
process can be generated. This will attract innovation and business
as well as eliminating the incentive to dump e-waste. In India,there are various organizations dealing with recycling of e-waste
