“E – waste “ is popular informal name for
electronic products nearing the end of
their useful life. E – waste are considered
dangerous as certain components of some
electronic products such as discarded
media and battery equipments if
improperly disposed can leach lead and
other substances into soil and
groundwater. Many of these products can
be reused or recycled in an environmentally
sound manner so that they are less
harmful to the ecosystem.
Technology is changing and people change their
electronic products like mobile phones, and
other electronic gadgets , second hand
electronic equipment are dumped. WHERE? I
don’t know ... But its all is E – WASTE ...
Recyclable electronic waste is sometimes
further categorized as a “commodity” while e
– waste which cannot be reused is
distinguished as “waste”. Both types of e waste have raised concern considering that
many components of such equipment are
considered toxic and are not biodegradable.
4. The Issue
• Due to breakneck speed of the modern
world at developing new electronics and
discarding old ones , a huge problem is
• The recycling procedures used in
disposal centres in sub - urban INDIA
lead to toxic materials like lead to seep
into the surrounding environment.
• This practice occur all over places like
China, Singapore, Pakistan, and
• The example being studied is the capital
city Bangalore of the state Karnataka ,
5. Case in point:
Bangalore is the capital city of
the Indian state of Karnataka. Located
on the Deccan Plateau in the southeastern part of Karnataka. “Since 1995 ,
Bangalore has been transformed from a
rich, urban, rice growing community to a
booming e-waste processing centre.
While rice is still growing in the fields,
virtually all of the available building
space has given way to providing many
hundreds of small and often specialized
7. Toxic Substances Present in
There are many harmful materials used in
consumer electronics like LEAD, PLASTICS,
MERCURY, and CADMIUM.
8. Effects of Toxins: LEAD
• Lead can be found in circuit boards and
monitor cathode ray tubes (CRTs). Lead is
particularly dangerous to the environment
because of its ability to accumulate and
persist in plants, animals, and microorganisms.
The bioaccumulation of lead in the human
body is particularly harmful because its
primary target is the central nervous system.
Lead can cause permanent damage to the
brain and nervous system, causing retardation
and behavioural changes. Infants and young
children are particularly susceptible because
of the impairment of cognitive and
behavioural development it can cause (Ryan et
9. Effects of Toxins: Cadmium
• Cadmium can be found in SMD (surface mount
device) chip resistors, infrared detectors and
semiconductors (Puckett et al. 2002: 11). Like
lead, cadmium is particularly toxic to humans
because it accumulates in the human body and
poses an environmental danger due to both
acute and chronic toxicity (Puckett el al.
2002: 11). Renal damage is the most common
effect of cadmium toxicity. Cadmium that
enters the system through the
gastrointestinal tract resides in human
kidneys with half – life of 10 – 20 years
(Nordberg et al. 1985).
10. Effects of Toxins: Mercury
• Mercury is the most prevalent toxic metal
found in e-waste. It is in circuit boards,
switches, medical equipment, lamps, mobile
phones, and batteries. Mercury transforms
into methyl mercury in water, where it can
accumulate in living organisms, typically via
fish, concentrating in large fish and humans at
the top of the food chain (Puckett et al.
2002: 11). Mercury is readily absorbed by the
human body, ultimately inhibiting enzymatic
activity and leading to cell damage (Boyer et
11. Effects of Toxins: Plastics
• The abundant component of e-waste is
plastics. Plastics comprise almost twenty –
three percent of a typical desktop computer
(Microelectronics 1995). They are used for
insulation, cables and housing for all
electronic devices; the variety of products
available for recovery complicates the de –
manufacturing process. Due to the complex
recovery process, large amounts of plastic e –
waste are disposed of through landfills,
incinerators and open burning, allowing toxic
substances to leach into the environment.
12. Effects on HUMANS
Several health issues associated with
the toxins found in the e – waste.
Damages kidney and liver.
Cause retardation, high blood pressure.
Disrupts endocrine system functions.
Cause eye and throat irritation.
13. Effects on surrounding
It has become a uncontrollable issue.
Contaminated leach pollute the ground
Uncontrolled burning and disposal are
Causes acidification of soil.
Not only leaching of the mercury poses
14. Combating e – waste
Though e – waste is a persisting issue,
efforts are being made around the
world to combat e – waste dumping in
countries like INDIA.
15. Management of e – waste
Due to advancement in techniques the
old instruments are outdated.
This necessitates implemental
India as a developing country needs
simpler, low cost technology for proper
management of e – waste.
In industries management of e – waste
should begin at the point of generation.
16. Management Options
Considering the severity of the
problem, it is imperative that
certain management options must
be adopted to handle the bulk ewastes.
Following are some of the
management options suggested for
the government, industries and the
17. Responsibilities of the
Government should set up
Government should provide an
adequate system of laws and
Government must encourage
research into the development and
production of less hazardous
18. Responsibility and Role of
Generators of waste should take
responsibility to determine the
output characteristics of wastes.
All involved person should be
properly qualified and trained in
handling e – waste in industries.
Companies should adopt waste
19. Responsibility of the
Donating used electronics to schools, non –
profit organizations, and lower – income
e – wastes should never be disposed with
garbage and other household wastes.
These wastes should be collected at a
separate site and they should be sent for
various processes like Reuse, Recycling,
20. The e – Day
Nearly 300 tonnes of old
computer equipment and
mobile phones were collected
free of charge during New
Zealand’s first national ë –
Day” in September 2007.
21. Can anyone say
Waste is an Illegal
Offence or not ?
YES, its an Illegal
Offence in INDIA
from 1st May 2012.
So from now STOP
Environmentally Safe: The cutting edge of
recycling technology is used to keep waste
by – products to an absolute minimum.
Economical: By using advanced techniques
we can extract greater quantities of base
products of reduced cost.
Convenient: Computer waste can be
collected on regular basis depending on
quantities which can either be deposited or
