Powerpoint presentation on E-Waste 2017

The document discusses electronic waste (e-waste), which refers to discarded electrical or electronic devices, highlighting its sources, types, and harmful effects on both the environment and human health. It emphasizes the importance of proper e-waste management and recycling to mitigate pollution and health hazards, as well as the alarming statistics that indicate a growing e-waste problem globally, particularly in India. The conclusion urges for increased awareness and government action to address e-waste disposal issues.

ELECTRONIC WASTE AN ENVIRONMENT KILLER…!!
TODAY’S ELECTRONIC GADGETS, TOMORROWS ELECTRONIC WASTE….!!
CONTENTS • What is E-Waste ? • Sources of E-Waste. • Types of E-Wastes. • Effects of E-Waste on environment. • Effect of E-Waste on human body. • How these become E-Waste. • Methods of disposal of E-Waste. • Why E-Waste Management? • Statistic's • Conclusion • References.
#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.
#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.
#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.
#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.
#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…..
#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.
#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.
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
#8. ADVANTAGES OF RECYCLING E-WASTE. • ASSET RECOVERY • REDUCTION OF NEED FOR LANDFILLS • REDUCTION OF JUNK AND CLUTTERS • RESALE AND REUSE • CREATION OF JOBS
#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.
#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.)
#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.
