E-waste is a major concern in today's world. It is AN ENVIRONMENT KILLER..!!. Its management is also of great importance. By Advait Vijay Mane, Mumbai, India.
E-Waste: A Hazard to Human Beings and EnvironmentDr Somvir Bajar
Management of the fastest-growing e-waste is a severe problem and has attracted worldwide attention. The electrical and electronic devices have become a part of everyone’s day to day life. Faster upgradation of electrical and electronic product is forcing consumers to add more e-waste to the solid waste stream. The growing problem of e-waste calls for greater emphasis on recycling e-waste. However, recycling of hazardous components in informal sector attracts several health-related problems and pollution to the environment, which call attempts for better e-waste management.
A Comprehensive Study On E Waste Management: Present Situation And Future Imp...Mosfiqur Rahman
Now-a-days, Electronic waste (e-waste) is one of fastest growing pollution problem for
environment and as well as threaten human body due to its presence in variety of toxic
substances as its disposal system are not properly managed. In Bangladesh, a large number of
electronic waste are generated but its subsequent handling, reuse, recycling and disposal are not
properly handled and can cause significant environmental and health hazards. At present, there is
lack of awareness about the hazards of electronic waste in Bangladesh. The electronic waste may
reuse, broken down into parts or disposed of completely. The present informal practice of
recycling is not carried out safely and it becomes a danger to human health and the surrounding
environment. This paper will share the management system of electronic disposal items and
trend of usage of electronic equipments. It will also share what hazards have been created from
this electronic waste, what are the present dumping practices and what rules are there in place for
dumping. It will also identify the level of awareness regarding e-waste and to determine a way to
reduce environmental hazards.
E-waste, or electronic waste, is a term used to describe any discarded or unwanted electrical or electronic device. It is a growing problem in today’s society as technology advances and new products become available.
Because of the
With the development of technology, People tend to use more electronic devices to make our tasks easier. But we carelessly add them to the environment.
This presentation is on the topic of proper Dispose of e-waste or electronic waste.
Hope it helps :)
Thank you!

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

4. #1.WHAT IS E-WASTE ?
• Electronic waste or e-waste describes discarded
electrical or electronic devices. Used electronics
which are destined for reuse, resale, salvage,
recycling, or disposal are also considered e-waste.
Informal processing of e-waste in developing
countries can lead to adverse human health effects
and environmental pollution.
5. #2. Sources of E-Waste.
1. Waste generated from the products used for data processing
such as computers, computer devices like monitor, speakers,
keyboards, printers etc.
2. Electronic devices used for entertainment like TV, DVDs, and CD
players.
3. Equipment or devices used for communication like phones,
landline phones, fax etc.
4. Household equipment’s like vacuum cleaner, microwave ovens,
washing machines, air conditioners etc.
5. Audio, visual components such as VCRs, Stereo equipment etc.
6. #3. TYPES OF E-WASTE
E-WASTE
Mouse,Keyboards
and other
electronic devices
Televisions
Mobile Phones
Personal electronic
devices
Laptops & monitors.
Scanners, printers &
copiers.
Audio-Video Equipment's.
7. #4. EFFECTS OF E-WASTE ON THE
ENVIRONMENT.
• Emissions from E-Waste create environmental
damage.
• Toxic chemicals from e-waste enter the "soil-crop-
food pathway,“
• These are non-biodegradable and cause soil
pollution.
• E-Waste dumping yards and nearby places are
polluted and cause health hazards.
8. #5. EFFECTS OF E-WASTE ON HUMAN BODY
Element Effect on human body.
Lead Damage to central and peripheral nervous systems , blood systems and kidney damage.
Affects brain development of children.
Chromium Asthmatic Bronchitis . DNA damage.
Cadmium Toxic irreversible effects on human health. Accumulates in kidney and liver. Causes neural
damage .Teratogenic.
Mercury Chronic damage to brain and respiratory system.
Plastics
including PVC
Burning produces dioxin. It causes reproductive and developmental problems ; Immune
system damage ; Interfere with regulatory hormones.
And many more…..
9. #6. HOW THESE BECOME E-WASTE?
Reasons:
Advancement in technology.
Changes in style fashion and status
Nearing the end of their useful life
Not taking precautions while
handling them.
10. #7. METHODS OF DISPOSAL OF E-WASTE
WHY WE SHOULD ENSURE SAFE DISPOSAL OF THESE?
1. Land fill disposal allows heavy metals to leach into ground water.
2. Incineration makes hazardous material airborne.
3. Acid baths are dangerous and cause water and soil contamination.
4. To ensure exported materials are handled properly.
11. Methods
Disassembly/Dismantling : It is the systematic removal of
components , parts or a group of parts or a subassembly from
a product in E-waste.
Upgrading : It includes comminuting and separation of materials
using mechanical/physical or metallurgical processing . Methods to
recover materials include incineration and refining.
Materials recovery : The materials are recovered by recycling
facilities. The plastic ,glass, metals can be recovered by sorting
them before mixing them with other waste.
THE MOST IMPORTANT METHOD IS RECYCLING
12. #8. ADVANTAGES OF RECYCLING E-WASTE.
• ASSET RECOVERY
• REDUCTION OF NEED FOR LANDFILLS
• REDUCTION OF JUNK AND CLUTTERS
• RESALE AND REUSE
• CREATION OF JOBS
13. #9.WHY E-WASTE MANAGEMENT ?
• Pollution of ground water.
• Acidification of soil.
• Emission of toxic fumes and gases.
• It is the fastest growing portion of municipal waste.
• Releases harmful gases into the air.
14. #10. STATISTICS
According to statistics we are generating more
than 40 million tons of e-waste a year and only
27% of this is recycled.
India is in the 5th position in the generation of
e-waste.(Being the largest user of smart phones this ranks may
increase in the future.)
15. #12. CONCLUSION
• E waste has emerged as one of the fastest growing waste
streams world wide today.
• Electronic gadgets, without proper disposal can cause
environmental harm
• Reuse and Recycle are more beneficial than simple disposal
• Designing of products using environment friendly raw items
can make a change.
• Awareness of e-waste should be given
• Government shall take steps to reduce e-waste disposal.
