Abstract
Since the discovery of automated computational devices, electronics have taken over the lifestyle of
whole world. They are now a very important component of day to day life and with the ever-growing
demand and supply the problem of E waste have also became a huge concern over the years. E waste
contain varying harmful pollutants ranging from heavy metals to organic and inorganic pollutants, which
when released in the environment cause great damage. Management of these E waste have been a priority
in the recent years with many policies aiming to decrease the hazardous contamination and effective
reusability of end of life electronics. There are many management options available which are used to
deal with this problem. All the management options have their own importance and drawbacks and, in
this review, we are going to take a look on these management options along with their salient features.
Keywords: E waste, management, disposal
1. Introduction
Information and communication technology have now become a part of every aspect of life of
population and became an industry with one of the largest reaches to the masses. As one the
fastest growing industry in the world (Radha. G., 2002; DIT, 2003)
[45, 12]
the use of computers,
cell phones, and other ICT equipment is expanding all over the world. Accompanying to their
benefits disposal after their end-of-life has many challenges. This increased demand has
resulted in an exponential increase in the waste produced by these electronics which is
commonly termed as E waste. There is a considerable growth in E waste production in last
decade which is contributed mainly by increase in demand and production of cheaper
electronic items. It has been estimated that by year 2020, 50 billion devices will be connected
to internet which is more than 6 times the population of world today (ILO, 2019)
[27]
. E waste
is relatively small portion of solid waste produced which amount to 2.1 billion metric tons
waste produced per year, but E waste defers from other solid waste like household waste,
wood and paper waste in that it contains hazardous and toxic substances like heavy metals,
Polychlorinated Biphenyls, along with various useful and precious metals (ILO, 2019)
[27]
. The
hazardous material leaches into the environment and cause environmental deterioration with
diseases like lead poisoning, hormonal imbalances, and cancer.
Most of the problem which is related to E waste arises due to faulty disposal and recycling
methods employed for these end of life products. Most common method of E waste disposal
consist of waste dumping in landfills, incineration, extended producer’s responsibility, and
recycling by formal and informal sectors. All these methods have their pros and cons and due
to their drawbacks leaching of harmful substance in the environment occurs resulting in
environmental pollution. Along with this there is a loss of many precious and rare earth
minerals (e.g., gold, silver, palladium, titanium, vanadium) which are very scarce in earth.
Dumping in landfills and incineration is mostly done in developed countries because of
excessive waste production and high labour cost, thus recycling becomes tedious and
economically unsound. Recycling of E waste is mainly done by informal sector of
underdeveloped and developing countries like Brazil, Ghana, China, India to which E waste is
exported by USA, Britain, European countries. In these developing and developed nations due
to lack of resources and technology, heavy environmental pollution and occupational exposure
to hazardous substances occur which when combined to poverty and lack of health
infrastructure leads to devastating social problems (Lines et al., 2016; Barba-Gutiérrez et al.,
2008)
[33, 4]
. But along with obstacles there are opportunities like recovery of precious and rare
earth metals which can provide raw materials to the market with a lower environmental
footprint than mining.
