There was a time when
computers had not been introduced to this world and a time when computers and
mobiles are in rampant creating huge amount of IT waste. We all know that how
much benefit we get from the IT products these days; at the same time the amount
of havoc those materials are creating on the planet in the form of e-waste.
They have huge impact on the environment. There are many electronic machines that
contain harmful substances such as lead and non-biodegradable substances. In
view of this, there should be safe electronic waste disposal methods.
There
are disposal methods such as burning, burying and dumping through which toxins
are released into our surrounding. The three common disposal methods that are
rampantly in use include dumping in landfills, melting components, incineration
are capable of contaminating water resources and causing air pollution
problems.
The
prevention of e-waste impact on our surrounding and animals can only be
possible by the proper disposal or reusing of the electronic waste. The
disposal and reusing the electronic waste can lower the health problem, reduce
greenhouse gas emissions and create jobs. The recycling can be done by sorting,
dismantling, and recovery of valuable materials. These things can be achieved
through refurbishing and reuse.
The
process of electronic waste involves melting of circuit boards, the ignition of
cable shield to recover copper wire or separating costly metals. The processes
used in the recycling and disposal of electronic waste such as electrolysis, electrolytic
recovery, osmosis, condensation, filtration, centrifugation, etc.
