Electronic waste, popularly known as‘ewaste’ can be defined as electronic equipments or products connects with power plug, batteries which have become obsolete due to: 1. Advancement in technology 2. Changes in fashion, style and status 3. Nearing the end of their useful life.

Classification of e waste E-waste encompasses ever growing range of obsolete products classified as:1. Electronic devices such as computers, servers, main frames, monitors, TVs & display devices 2. Telecommunication devices such as cellular phones & pagers, calculators, audio and video devices, printers, scanners, fax machines, refrigerators, air conditioners,

Electronic components such as chips, processors, mother boards, printed circuit boards, industrial electronics such as sensors, alarms, sirens, security devices, automobile electronic devices

Present Scenario • Every house having electronic equipments • • Business necessity • • More than 40-50 million tons e-waste worldwide / year • • Asia-estimate of 12 million tons/ year • • 50-80% e-waste collected in US and other developed countries exported to third world countries • • E-waste is still the fastest growing municipal

• 2005- 2.6 m tons in India of which 12.6% recycled • • Growth – 30% / yr • • 20 to 24 million computers and televisions are added to storage each year 

• 400 m units to be scrapped by end of decade • • 8% of municipal waste in EU and 2-5% in US • • 1-20 kg per person/p.a and growing at 3 times faster than the municipal waste.

quick Facts • 1200 tons of scrap / yr , Only 11% of e-waste get recycled . • • India's hospitals to see patients with 10 times the expected level of lead in their blood. • • In India, a water sample revealed levels of lead 190 times as high as the drinking water standard set by the WHO. •

EFFECTS OF e-WASTE ON HUMAN HEALTH Chemical

Uses in Electronics Health Effects

Lead

Glass and PC cathode ray tubes Damage to nervous system, circulatory as radiation shield systemand kidneys; serious effects on brain development

Aluminum

Conductivity

Skin rashes, asthma, linked to Alzheimer’s Disease

Nickel

Magnetics

Chronic bronchitis, impaired lung functions

Beryllium

Thermal conductivity

Lung damage, chronic beryllium disease

Chromium

Decorative, hardener(steel)

Damage to liver, kidneys, increase possibility of lung cancer, asthma

Cadmium

Battery. Blue-green phosphor emitter

Kidney disease, bone fragility

Mercury

Batteries, switches

Chronic brain, kidney, lung and fetal damage . 

Composition of EWaste

DID YOU KNOW

Over 75 million current mobile users expected to increase

400 MILLION BY 2009 end

EFFECTS ON ENVIRONMENT  Pollution of Ground Water.  Acidification of soil.  Air pollution.  e-Waste accounts for 40% of LEAD and 70% of heavy matals found on Landfills.

Effect of the trade 

• 330000 tons generated in 2007, of which 150000 tons in India • Jun 05, 2008- half ton e-waste generated in Mumbai • Sep 24, 2007- 10000 tonnes in delhi, with 25000 workers including children • Indian hospitals are treating patients who have 10 times the normal level of lead in their blood •

• Microsoft's new operating system launched in January -- Windows Vista -- will make many older machines obsolete and create a "tsunami of ewaste" exported to developing nations, according to Jim Puckett, coordinator for the Basel Action Network. 

Reasons for growth • Globalization • high obsolescence rate • Inability of technology to support upgradation • Less costly components used in the electronic equipments • Low cost of products • Purchasing power increase

Responsibilities of the Citizen  Reuse

  Donating used electronics to schools, non-profit organizations, and lower-income families.

  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, and Donating.

RESPONSIBILITY OF 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 equipments

Poison factory

CONCLUSION • E-Waste is going to create alots of problem • • E-Waste mangement is of outmost important • • Proper management is necessary to minimize its ill effects on nature and human beings

CONCLUSION Reduce

RECOVER

RECYCLE

REUSE
