The document discusses electronic waste (e-waste), its sources, adverse effects on human health and the environment, and strategies for reduction, reuse, and recycling. E-waste comprises harmful substances that can damage human health and contaminate air, soil, and water when improperly disposed of. The importance of recycling, along with the statistics illustrating the growing global e-waste problem, underscores the necessity for environmentally friendly practices and government interventions.

3. Electronic waste, abbreviated as ‘e-waste’ is a
term used to describe old, end-of-life
electronic appliances such as computers,
laptops, TV’s, radios, refrigerators etc., which
have been discarded by users. E-waste
comprises of numerous valuable but harmful
substances that can cause an adverse effect on
human health. Recycling e-waste can be
dangerous if not done using suitable
techniques and measures.
INTRODUCTION

4. 1. Waste generated from the products used for
data processing such as computers, computer
devices like monitor, speakers, keyboards,
printers etc.
2. 2. Electronic devices used for entertainment like
TV, DVDs, and CDplayers.
3. 3. Equipment or devices used for
communication like phones, landline phones,
fax etc.
4. 4. Household equipment's like vacuum cleaner,
microwave ovens,washing machines, air
conditioners etc..
5. 5. Audio, visual components such as VCRS,
Stereo equipment etc.
SOURCES OF
E-WASTE

5. EFFECTS ON HUMAN HEALTH
• Damage to central and peripheral nervous systems, Blood
systems and kidney damage
• Affects brain development of children.
• Chronic damage to the brain.
• Respiratory and skin disorders due to bioaccumulation in
fishes.
• Asthmatic bronchitis.
• DNA damage
• Reproductive and developmental problems.
• Immune system damage.
• Lung Cancer.
• Damage to heart, liver and spleen.

6. EFFECTS ON ENVIRONMENT
The Negative Effects on Air
Contamination in the air occurs when e-waste
is informally disposed by dismantling,
shredding or melting the materials, releasing
dust particles or toxins, such as dioxins, into
the environment that cause air pollution
The Negative Effects on Soil
When improper disposal of e-waste in regular
landfills or in places where it is dumped
illegally, both heavy metals and flame
retardants can seep directly from the e-waste
into the soil, causing contamination of
underlying groundwater or crops
The Negative Effects on Water
After soil contamination, heavy metals from e-
waste, such as mercury, lithium and barium,
then leak through the earth even further to
reach groundwater. When these heavy metals
reach groundwater, they eventually make their
way into rivers and lakes etc

7. HOW THESE BECOME E-WASTE?
Reasons :
Advancements in technology.
Changes in style fashion and status.
Nearing the end of their useful life.
Not taking precautions while handling them.

8. HOW TO REDUCE E-WASTE
• Reuse as often as possible
• Educate yourself on what gets put
into your electronics.
• Be a good consumer.
• Look for an environmentally friendly label.
• Consider limiting the number of electronics
you own.
• Recycle, recycle, recycle.
• Understand security issues.
• Maintain what you have.

9. “Reuse” is an important component of keeping material out of the
waste stream. E-waste may make its way into scrapyards, mixed in with
cars, old appliances and industrial scrap handled by the scrap metal
recycling industry. Individual recyclers have different approaches for
how to handle these items, but more progress is being made on how to
extract valuable material and move these items through the recycling
process.
REUSE OF E-WASTE

10. RECYCLE OF E-WASTE
E-waste recycling refers to the reprocessing and re-use of these
electronic wastes. It is simple. It is a process that seeks to recover
material from electronic waste. This way, you can use them in new
electronic products.
Recycling of e-waste is a growing trend and was initiated to protect
human and environmental health mainly due to the widespread
environmental pollution impacts of e-waste.

11. ADVANTAGES OF RECYCLING
• Electronic products are comprised of valuable materials such as
precious metals like gold, silver and platinum along with copper,
aluminum, plastic and glass.
• Reclaiming valuable materials from the recycling process means
there will be decreased demand for new raw materials.
• Using recycled material will also help reduce greenhouse gas
emissions produced when manufacturing or processingnew product
known as “virgin material.”
• Discarded electronic devices can also be kept out of the landfill if
they are refurbished, reused and donated to a worthy cause.

13. According to statistics we are generating morethan 40 million tons of e-
waste a year and only 27% of this is recycled. India is in the 5th position
in the generation ofe-waste.(Being the largest user of smart phones this
ranks may increase in the future.)
STATISTICS
According to the data received in 2007 about 70 % of e- waste of the
world reaches China and the rest to Africa and India.
Due to cheap labourthey have become the world’s dumping station of
e- waste. In Ghana about 20% of their population are working on e-
waste which they use after reconditioning them. Poverty is the main
reason for third world countries to consume e-wastes from Europe and
USA.

14. In 2017 it was reported by Global E-waste Monitor report that e-waste
has increased by 44.7 million metric tonnes(8 percent) from 2014 to
2016. The number is expected to rise to nearly 52.2 million metric tons
by 2021 (17 percent) globally.

15. 1. E waste has emerged as one of the fastest growing waste streams
world wide today.
2. Electronic gadgets, without proper disposal can cause
environmental harm
3. Reuse and Recycle are more beneficial than simple disposal
4. Designing of products using environment friendly raw items can
make a change.
5. Awareness of e-waste should be given
6. Government shall take steps to reduce e-waste disposal.
