Electronic waste or e-waste is one of the rapidly growing
problems of the world. E-waste comprises of a multitude of components, some
containing toxic substances that can have an adverse impact on human health and
the environment if not handled properly. In India, e-waste management assumes
greater significance not only due to the generation of its own e-waste but also
because of the dumping of e-waste from developed countries. This is coupled
with India's lack of appropriate infrastructure and procedures for its disposal
and recycling.
The composition of WEEE is very diverse and differs in
products across different categories. It contains more than 1000 different
substances, which fall under ‘hazardous’ and ‘non-hazardous’ categories.
Broadly, it consists of ferrous and non-ferrous metals, plastics, glass, wood
and plywood, printed circuit boards, concrete and ceramics, rubber and other
items. Iron and steel constitutes about 50% of the WEEE followed by plastics
(21%), non-ferrous metals (13%) and other constituents. Non-ferrous metals
consist of metals like copper, aluminium and precious metals, e.g. silver,
gold, platinum, palladium, etc. The presence of elements like lead, mercury,
arsenic, cadmium, selenium and hexavalent chromium and flame retardants beyond
threshold quantities in WEEE classifies them as hazardous waste.
The production of electrical and electronic equipment (EEE)
is one of the fastest growing global manufacturing activities. Rapid economic
growth, coupled with urbanization and a growing demand for consumer goods, has
increased both the consumption and the production of EEE. The Indian IT
industry has been one of the major drivers of change in the economy in the last
decade and has contributed significantly to the digital revolution being
experienced by the world. New electronic gadgets and appliances have
infiltrated every aspect of our daily lives, providing our society with more
comfort, health and security and with easy information acquisition and
exchange. E-waste broadly covers waste from all electronic and electrical
appliances and comprises of items such as computers, mobile phones, digital
music recorders/players, refrigerators, washing machines, televisions and many
other household consumer items. The increasing ‘market penetration’ in the
developing countries, ‘replacement market’ in the developed countries and ‘high
obsolescence rate’ make e-waste one of the fastest waste streams.
Studies so far reveal that the total e-waste generation in
India is approximately 1,46,000 tonnes to 3.3 lakh tonnes a year and is
expected to touch 4.7 lakh tonnes by 2011. The projected growth for e-waste
generation for India is about 34% year on year. Of the total e-waste generated
in the country, western India accounts for the largest population at 35%, while
the southern, northern and eastern regions account for 30, 21 and 14%,
respectively. The top states in order of highest contribution to WEEE include
Maharashtra, Andhra Pradesh, Tamil Nadu, Uttar Pradesh, West Bengal, Delhi,
Karnataka, Gujarat, Madhya Pradesh and Punjab. The city-wise ranking of the
largest WEEE generators is Mumbai, Delhi, Bangalore, Chennai, Kolkata,
Ahmedabad, Hyderabad, Pune, Surat and Nagpur. An estimated 30,000 computers
become obsolete every year from the IT industry in Bangalore alone. As many as
1000 tonnes of plastics, 300 tonnes of lead, 0.23 tonnes of mercury, 43 tonnes
of nickel and 350 tonnes of copper are annually generated in Bangalore.
EEEs are made of a multitude of components, some containing
toxic substances that have an adverse impact on human health and the
environment if not handled properly. Often, these hazards arise due to the
improper recycling and disposal processes used. It can have serious
repercussions for those in proximity to places where e-waste is recycled or
burnt. Waste from the white and brown goods is less toxic as compared with grey
goods. A computer contains highly toxic chemicals like lead, cadmium, mercury,
beryllium, BFR, polyvinyl chloride and phosphor compounds.
Government action on E-Waste include Draft Hazardous
Materials (Management, Handling and Trans-boundary movement) Rules, 2007
(dated: September 28, 2007), part of the Environment Protection Act, 1986.
India is a signatory to the Basel Convention. Basel Convention is the United
Nations Environment Programme on the control of Trans-boundary Movement of
Hazardous wastes and their disposal. There is no policy on e-waste, although
some parts of computers could be considered as hazardous waste.
The solution for the e-waste crisis lies in ‘prevention at
the manufacturing source’ or the ‘precautionary principle.’ This can be done by
employing waste minimization techniques and by a sustainable product design.
Some recycling procedures require improvements; up-gradation (both in skills
and technologies) and some have to be abandoned altogether due to severe risks
for health and the environment. Lack of clarity on the issue of e-waste and the
inability of current hazardous waste rules to govern and effectively monitor
the e-waste recycling are some of the prime reasons for experts and members of
civil society demanding a separate set of rules to guide and control these
processes. Producers must be responsible for the entire lifecycle of their
products. In developed countries, several efforts have been made on this front.
Several dozen cities in the states of California and Massachusetts, including
San Francisco, also have passed resolutions supporting ‘producer take back’
rules. Wipro InfoTech has launched an e-waste disposal service for end
customers. Others offering recycling options include Dell, HP and Apple. The
current awareness regarding the existence and dangers of e-waste are extremely
low, partly because the e-waste being generated is not as large as in developed
countries. Urgent measures are required to address this issue.
India is placed in a very interesting position. The need of
the hour is an urgent approach to the e-waste hazard by technical and
policy-level interventions, implementation and capacity building and increase in
public awareness such that it can convert this challenge into an opportunity to
show the world that India is ready to deal with future problems and can set
global credible standards concerning environmental and occupational health.
