Introduction:
The process of E-waste
recycling refers to recycling of electronic devices after then became obsolete.
As the items can’t be disposed like generic garbage due to containment of
harmful chemical compounds, there are specific organizations who deal with such
recycling.
Current scenario in India:
According
to the data provided by CPCB (Central pollution control board), as of 2016, there
are 178 units of recyclers in India compared to 138 in 2014. Karnataka tops the
list with 57 units of recyclers, followed by Maharashtra with 32 units. The E-waste recyclers in India use advanced and sophisticated techniques to
treat the e-wastes and make good use out of them. With the proper technique it
helps in optimum recycling of e-waste which is then reused and resold in the
market. Hence, preventing the harmful effect of toxicity from such wastes is
primary. As of now India collectively has a capacity of 438085.62 MTA as of
2016 according to the data provided by CPCB.
Process of e-recycling:
The work of E Waste Recyclers in India involves of manually sorting the
items came for e-recycling. Rechecking the quality of the batteries and manual
dismantling are the major process. The e-waste items are dismantled and
categorized as core materials and constituents. Then they are again categorized
as reusable or not. After that all the parts which can’t be dismantled are
shredded with small pieces. The small pieces then are categorized as finer
e-waste pieces.
The finer pieces are then put into the conveyer belt for
a shaking process to further spreading them out and breaking them again. The
extracted dust from the process is discarded in such a way that it doesn’t
degrade the environment.
Over-band Magnetic process is used to separate the
magnetic process along with steel and iron from the debris. Then the rests are
separated into metallic and non-metallic debris. The metals are sold as raw
materials or used for remanufacturing. By the use of water the plastic
materials are separated from the glass and then further resold as raw
materials.
Re-usable components after recycling:
Plastic recycle compounds are use to make plastic trays, sleepers, holders
etc. Scrap metals are used to make new steel and iron materials. The glass
which are extracted are use for making new screens for CRT monitors and TV
sets.
The Nickels, cadmium, steel and cobalt are extracted from old batteries and
used for new manufacturing of batteries and also for steel creation.
