Researchers found Eco-friendly way of recycling e-waste.
Researchers
from Indian Institute of Science have found a different way to recycle the
Electronic waste or e-waste in an environmentally friendly manner.
About the
process:
The new way
is based on idea of crushing e-waste into nanosize particles using a ball mill
at very low temperature ranging From -50 to -150 degree Celcius.
Once it
curshed for 30 minutes, different forms of materials like metals, oxides and
polymer, which forms the electronic items get physically reduced into their
constituent phases.
It is then
separated without using chemicals and usage of low temperature grinding
eliminates noxious emission.
About
E-waste:
- E-waste also called electronic waste, which means that electronic products that have become un wanted or useless or non-working or obsolete
- E-waste which affects the human body because it contains plethora of toxic components including Mercury, Lead, Cadmium, Polybrominated Flame Retardants, Barium and Lithium
- If electronic waste thrown in landfills, toxins of electronic may leach into ground water which affect local resources
- If electronic waste burned it create cancer producing dioxin which released in Air.
- In simple terms, shredding, burning, and dismantling the electronic waste , emmission from this recycling will affect health as well as environment
