5. WHAT IS ELECTRONIC WASTE?
• Electronic waste or e waste is any broken and
unwanted electrical and electronic appliances.
• E-waste include computers, Mobiles, Electronic
entertainment and other items that have discarded
by original position.
6. SOURCE OF E-WASTE
• IT and Telecon equipment
• Large & small household
Equipment
• Consumer and lighting
equipment
• Medical devices
• Video games
• Monitoring and tool
equipment
10. LAPTOPS AND COMPUTER USERS IN
PAKISTAN
• Almost 6.5millionlaptop users
• Almost 9 millioncomputer users
• Pakistan generates about 48.5 million tons of solid waste a year, which has been
increasing more than 2 percent annually.
13. ELECTRONIC WASTES IN WORLD
• The new study from United Nations University found that 43 million tons of
electronic waste was generated in 2016.
• A rise of eight percent from 2014, the fastest growth of any type of refuse, and
double the rate of plastic refuse.
• It is the equivalent in weight to almost nine Great Pyramids of Giza, or 4,500 Eiffel
Towers.
14. WHY SO MUCH ADO ABOUT E-WASTE?
• An estimated 50 million tons of E-wastes are produced each year.
• The USA discards 30 million computers each year & 100 million phones are disposed
of in Europe each year.
• The environmental Protection Agency estimates that only 15-20% of E-Waste is
recycled, the rest of these electronics go directly into landfills and incinerators.
• E-waste contains several different substances and chemicals, many of which are
toxic and are likely to create adverse impact on environment and health, if not
handled properly.
18. CATEGORIES OF E-WASTES
• Large Household Appliances
• Small household appliances
• IT & Telecommunication equipment
• Consumer equipment
• Lighting equipment
• Electrical and electronic tools
• Toys & sport equipment
• Medical devices
• Monitoring and control instruments
• Automatic dispensers
19. HOW THESE BECOMES E-WASTE ?
Advancement in technology.
Changes in style, fashion & status.
Nearing the end of their useful life.
Not taking precautions while handling them.
20. E-WASTE DISPOSAL
A PROBLEM & CHALLENGE
• Landfill disposal allows heavy metals to leach into ground water.
• Incineration makes hazardous material airborne.
• Acid baths are dangerous and cause water and soil contamination.
• Exported materials are handled improperly
• Most E-Wastes goes to China, India and Africa:
• 1.Workers are untrained and uneducated in safe handling of electronic wastes.
• 2.No Environmental Protection Laws.
23. RECYCLING
• Recycling recovers valuable materials from
old electronics that can be used to make new
products. As a result,
• we save energy,
• reduce pollution,
• reduce greenhouse gas emissions
• and save natural resources by extracting
fewer raw materials from the earth.
27. GREEN COMPUTING
• Green computing is the
environmentally responsible and
eco-friendly use of computers and
their resources.
• It is also the study of designing,
engineering, using and disposing of
computers in a way that reduces
their environmental impact.
28. ADVANTAGES OF GREEN COMPUTING
• Reduces the amount of pollutants in the surroundings.
• It reduces the amount of heat produced from the electronic devices.
• It encourages the use of renewable resources.
• It promotes effective utilization of natural resources.
• It reduces the risk existing in PC’s due to chemicals that cause nerve
damage in humans.
30. CONCLUSION
• As far as the e-waste is concerned it has emerged as one of the fastest growing waste
streams world wide today.
• Electronic equipment is one of the largest know sources of heavy metals without
effective collections, reuse, and recycling systems, they will be dangerous to
environment.
• Reuse and recycling of electronic equipment is a beneficial alternative than disposal.
• Product design by using safe and environment friendly raw materials and most
emerging technologies.
• Awareness of E-Wastes.
• Implementation of legislation.
