ELECTRONIC WASTE MANAGEMENT
IN INDIA
Babuponnusami.A, PalanivelMurugan.M, Suresh.A.KDepartment of Chemical Engineering, Adhiparasakthi Engineering College
ababupo [email protected], [email protected],[email protected] - The current practices of e-waste
management in India suffer from a number of
drawbacks like the difficulty in inventorisation,
unhealthy conditions of informal recycling, poor
awareness and reluctance on part of the corporate
to address the critical issues. Electronic waste or e-
waste consists of obsolete electronic devices which
are caused to the environmental change. The e-
waste material which including iron, copper,
aluminum, gold and other metals over 60%, while
plastics account for about 30% and hazardouspollutants only about 2.7%(Widmer et al, 2005). In
this paper contains what is the current scenario of
e-waste management in India. The sources of the e-
waste are IT and Telecom industries, large and
small household appliances, electronic and
electrical tools, medical devices, monitoring and
control equipment. At the end of 2010, 500 million
mobile users (80%), 80million computers (20%)
over 15 million old PCs are ready to disposal and
also TV (18%). Nowadays the e-waste disposal is
done by unsafe method by manually informal
recycling as lack of awareness. These are disposed
with safety handling by the way of collecting and
transportation, treatment and proper disposalsystem. The recyclers zone also involved in the
disposal of e-waste management system. 2009 They
are collecting e-waste from material recovery
technologies. In country the recyclers are often
handled open roasting, smelting and acid bath for
getting useful component from e-waste. We can
resolve the e-waste minimization by the
optimization usage of electronic things and
equipment in household and industry also. The
paper highlights the associated issues and
management of e-waste to emerge this problem, inthe light of initiatives in India.
Keywords: obsolete electronic device, environmental
change, sources of e-waste, material recoverytechnologies, optimization usage.
1. INTRODUCTION
E-waste is defined as the electronic
equipment/products that connect with power plug,
Batteries which have become obsolete due to
advancement in technology, changes in fashion, style
and status, near the end of their useful life. The
electronic industry is the worlds largest and fastest
growing manufacturing industry (RATHA 2002).The
main problems of e-waste are the most rapidlygrowing. It is a crisis of not quantity alone but also a
crisis born from toxics ingredients, posing a threat to
the occupational health as well as the environment.
The rapid technology change, low initial cost, high
obsolescence rate have resulted in a fast growing
problem around the globe, legal framework, proper
collection system missing. Inhuman working
conditions for recycling. The e-waste fraction
including iron, copper, aluminum, gold and other
metals over 60%, while plastics account for about30% and hazardous pollutants comprise only about
2.7% (Widmer et al.., 2005). The classification of e-
waste is shown in table 1.1.Mechanism of e-waste
trade can be explained in terms of three elements.
These elements are given below. Material flow
along the Life cycle of electrical and electronic
equipment including the phase of obsolescence within
a Geographical boundary forms the basis of e-waste
generation in cities/countries.

2. INDIANCURRENT SCENERIO ON E-WASTE
PRODUCTION
According to a report of Confederation ofIndian Industries, the total waste generated by
obsolete or broken down electronic and electrical
equipment in India has been estimated to be 1,46,000
tons per year (Kurian Joseph,2007). The results of a
field survey conducted in the Chennai, a metropolitan
city of India to assess the average usage and life of the
personal computers (PCs), television (TV) and mobilephone showed that the average household usage of the
PC ranges from 0.39 to 1.7years, depending on the
income class (Kurian Joseph, 2007). In the case of TV
it varied from 1.07 to 1.78years and for mobile
phones varied from 0.88 to 1.7years.
The low-income households use the PC for
5.94 years, TV for 8.16 years and the mobile phonesfor 1.63 years. Further, it is growing at a faster rate.
The growth rate of the mobile phones (80%) is very
high compared to that of PC (20%) and TV (18%).
The public awareness on e-waste and the willingness
of the public to pay for e-waste management as
assessed during the study based on an organized
survey revealed that about 50% of the public are
aware of environmental and health impacts of the
electronic items. The enthusiasm of public to pay for
e-waste management ranges from 3.57% to 5.92% of
the product cost for PC, 3.94% to 5.95% for TV and
3.4% to 5% for the mobile phones. The e-waste
production in Indian cities are shown in table 2.1

'There are 36,165 hazardous waste generating
industries in the country. 6.2 million Tonnes of
hazardous waste is generated by them every year, of
which land fillable waste is 2.7 million tonnes,
incinerable 0.41 million tonnes and recyclablehazardous waste is 3.08 million tonnes,' the ministrysaid. As per the hazardous waste (management,
handling and trans-boundary movement) rules, 2008,
all units handling e-waste need to register with the
CPCB and the hazardous wastes generated should be
given to an authorized recycler or re-user.

3. E-WASTES MANAGEMENT
The current practice on e-waste management in Indiawas not up to the level due to the various reasons as
shown in Fig.1.
E-wastes are currently managed in the following
steps.
1.E-waste collection and transportation system2.E-waste treatments system3.E-waste disposal system
E-waste collection system consists of
producer/retailer take back system. Since e-waste ishazardous in nature, it is collected, stored and
transported under controlled conditions. Each of the
agencies should have its own e-waste collection and
storage centers. The collection methods will vary
based on distance, rural or urban patterns and the size
of collected appliances. Some categories will require
specific collection routes like flatbed collection (for
refrigerators and other reusable household
appliances).

Unit operations involved in first level of
treatment
Removal of all liquids and gases Dismantling (manual) Segregation
Output:
1. Segregated hazardous wastes like CFC, Mercury
(Hg) Switches, CRT, batteries and capacitors.
2. Decontaminated e-waste consisting of segregated
non-hazardous e-waste like plastic, circuit board and
cables
3.2. POSSIBLE STEPS FOR DISPOSING E-
WASTE
Step 1: Determine e-waste trade value chain in a
city/geographic region.
Step 2: Determine existing and future item-wise e-
waste inventory in a city/geographic region.
Step 3: Determine item-wise e-waste quantities
collected and segregated in informal/unorganized and
formal/organized sectors.
Step 4: The output of above step will give an idea of
existing capacity of informal/unorganized and
formal/organized sectors in e-waste treatment
Step 5: Determine recovery quantities of items of
economic value from existing e-wise quantitiestreated in informal/unorganized and formal/organizedsectors.
Step 6: Determine existing item-wise e-waste fraction
quantities disposed and disposal procedure using the
data collected from survey.
4. CONCLUSIONSolid waste management, which is a mammoth
task in India, is becoming more complicated by the
assault of e-waste, particularly computer waste. There
exists an urgent need for assessment of the current
and future scenario including quantification,
characteristics, existing disposal practices,environmental impacts etc. Policies should include
development of e-waste regulation, control of import
and export of e-wastes. Take-back and exchange
program can be followed for e-waste reduction. End-
of life management should be made a priority in the
design of new electronic products.
