Subject : Electronic Waste

3. Definition
E-waste or electronic waste is created when
an electronic product is discarded after the end of
its useful life. The rapid expansion
of technology and the consumption driven society
results in the creation of a very large amount of e-
waste in every minute.

4. Amount of electronic waste
worldwide
E-waste is considered the “fastest-growing waste
stream in the world”with 44.7 million tonnes
generated in 2016- equivalent to 4500 Eiffel
towers. In 2018, an estimated 50 million tonnes of
e-waste was reported, thus the name ‘tsunami of
e-waste’ given by the UN. Its value is at least
$62.5 billion annually.

5. E-waste legislative frameworks
Looking at European continent, European Union
has addressed the issue of electronic Waste by
introducing two pieces of legislation.The first
legislation, named "The Directive on waste
electrical and electronic equipment" or "WEEE
directive" entered into force in 2003.

6. Trade Issues
One theory is that increased regulation of
electronic wastes and concern over the
environmental harm in nature economies creates
an economic disincentive to remove residues prior
to export. Critics of trade in used electronics
maintain that it is still too easy for brokers calling
themselves recyclers to export unscreened
electronic waste to developing countries, such as
China, India and parts of Africa, thus avoiding the
expense of removing items like bad cathode ray
tubes (the processing of which is expensive and
difficult.

7. Environmental impact
E-Waste
Component Process Used
Potential
Environmental Hazard
Cathode ray tubes Breaking and removal of
yoke, then dumping
Lead, barium and release
of toxic phosphor
Printed circuit
board
De-soldering and removal of
computer chips;
Air emissions and
discharge into rivers of
glass dust, tin, lead,
Chips and other
gold plated
components
Chemical stripping using
nitric and hydrochloric acid
and burning of chips
PAHs, heavy metals,
brominated flame
retardants discharged
directly into rivers
Plastics from
printers,
keyboards,
monitors, etc.
Shredding and low temp
melting to be reused
Emissions of brominated
dioxins, heavy metals, and
hydrocarbons

8. Human health and safety
Residents living around the e-waste recycling
sites, even if they do not involve in e-waste
recycling activities, can also face the
environmental exposure due to the food, water,
and environmental contamination caused by e-
waste, because they can easily contact to e-waste
contaminated air, water, soil, dust, and food
sources. In general, there are three main exposure
pathways: inhalation, ingestion, and dermal
contact

9. Recycling
Recycling is an essential element of e-waste
management. Properly carried out, it should
greatly reduce the leakage of toxic materials into
the environment and mitigate against the
exhaustion of natural resources. However, it does
need to be encouraged by local authorities and
through community education. Less than 20% of e-
waste is formally recycled, with 80% either ending
up in landfill or being informally recycled – much of
it by hand in developing countries, exposing
workers to hazardous and carcinogenic
substances such as mercury, lead and cadmium.
