Electronic waste is an alarming
problem faced globally in today’s constantly changing world of technological
innovations. The major challenge is to create various innovative and
cost-effective ways for decontaminating polluted environments so that they are
safe for human habitation, consumption and functioning of various ecosystems
that support life. To date, for the management of e-waste no sound eco-friendly
technique is available. Hence, biological approach using microorganisms is
currently being applied for recovering leached metals from contaminated soil,
groundwater, surface water polluted by e-waste, removing toxicity and
decontamination of these abiotic components polluted due to e-waste. There are
different technologies used for management of e-waste using microorganisms
which include microremediation, phytoremediation and vermiremediation.
Microremediation involves the use of various microorganisms, phytoremediation
the use of plants and symbiotic microorganisms, whereas vermiremediation
involves the use of earthworms and necessary associated microbes for e-waste
management. These technologies are becoming attractive alternatives as compared
to the primitive disposal technologies because they are cost effective, work at
ambient temperatures, do not have any major environmental impacts, generate minimum
secondary waste and have an inherently aesthetic nature. This paper summarizes
the status of e-waste and its harmful effects on life as well as environment
and use of innovative microbial biotechnological approaches for handling of
e-waste and metal recovery thereof.
