• The term E-waste applies to all the wastes
from or caused by electronic Items.
• Unwanted or unusable electronic products
such as computers, computer
peripherals, televisions, VCRs, DVD
Players, stereo equipment, hand cell phones
are commonly referred to as ‘electronic

E-Waste In INDIA
• As per a report by Ministry of Environment and Forests
(MoEF), India generated 1,46,800 tones of E-waste was
generated in the year 2005 and the number is expected to
reach 8,00,000 tones by 2012.
• 65 cities generated more than 60% of the total E-waste
generated in India.
• Top E-waste generating cities in India are
Delhi, Bangalore, Chennai, Kolkata, Ahmedabad, Hyderabad, P
une , Surat and Nagpur. And top E-waste generating states in
India are Maharashtra, Tamil Nadu, Andhra Pradesh, Uttar
Pradesh, Gujarat, West Bengal, Delhi, Karnataka, MP and

• Due to advancement in techniques the
old instruments are becoming outdated.
• India as a developing country needs
simpler, low cost technology for proper
management of E-waste.
• Industrial Revolution.
• There mismanagement can lead to the
• This waste is not Eco-friendly.
• Hence there is a need to check this electronic
waste pollution by proper management.
• In industries management of e-waste should
begin at the point of generation.
• Waste minimization in industries involves
1. inventory management,
2. production-process modification,
3. volume reduction,
4. Recovery and reuse.
• Proper control over the materials.
• Reducing both the quantity of hazardous
materials & amount of excess raw materials in
• All materials be approved prior to purchase.
• Hazardous material replaced by nonhazardous material if available.
• Remove the hazardous portion of a waste
from a non-hazardous portion.
• 2 general categories:
– Source segregation
– Waste concentration
• Source segregation
• Segregation of wastes is in many cases a simple and
economical technique for waste reduction.
• Wastes containing different types of metals can be treated
separately so that the metal value in the sludge can be
• Waste concentration
• Concentration of a waste stream may increase the
likelihood that the material can be recycled or reused.
• Methods include gravity and vacuum filtration, ultra
filtration, reverse osmosis, freeze vaporization etc.
Recovery and Reuse
• Eliminate waste disposal costs, reduce raw
material costs and provide income from a
• Physical and Chemical techniques are
available to reclaim a waste material.
• For example, a printed-circuit board
manufacturer can use electrolytic recovery to
reclaim metals from copper and tin-lead
Sustainable product design
• Rethink the product design
– Efforts should be made to design a product with fewer
amounts of hazardous materials.
• Use of renewable materials and energy
– Solar computers also exist but they are currently very
• Use of non-renewable materials that are safer
– product is built for re-use, repair and/or
– Dell and Gateway
Considering the severity of the problem, it is
imperative that certain management options
must be adopted to handle the bulk e-wastes.
Following are some of the management
options suggested for the government,
industries and the public.
Responsibilities of the Government
• Government should set up regulatory agencies.
• Government should provide an adequate
system of laws and controls.
• Government must encourage research into the
development and production of less hazardous
Role Of Industries
• Generators of wastes should take responsibility
to determine the output characteristics of
• All involved person should be properly
qualified and trained in handling e-waste in
• Companies should adopt waste minimization
Responsibilities Of Citizen
• Donating used electronics to schools, nonprofit organizations, and lower-income
• E-wastes should never be disposed with
garbage and other household wastes.
• These wastes should be collected by some
persons and they should be sent for various
processes like Reuse, Recycling, and
• E-waste is going to create lot of problems in
• E-Waste management is of utmost importance.
• Proper management is necessary to minimize
its ill effects on human beings and nature.
