E- Waste
E-WasteElectronic waste or e-waste is any broken or unwanted electrical or electronic appliance.
E-waste includes computers, entertainment electronics, mobile phones and other items that have been discarded by their original users.
Composition includes :• High-quality plastics• Valuable metals• Toxic and hazardous pollutants
Indian Scenario: Numbers tell the story
Historic Waste: Over 20 Lakhs old PCs ready for disposal in India
Every year, 30000 computers become obsolete
Last year, 8.1 million PCs and notebooks sold
More than 100 thousand servers sold
By May 2012, India had 929.37 million mobile phone base
…………And every month, 10 million new mobiles are added
It has the world's third-largest Internet user-base with over 137 million as
of June 2012.
IT & Telecom sector accounts for 25% of the e-waste pie:
Washing Machine,ACs, Dryers,
VacuumCleaner, toaster, Irons
30%
Refrigirators20%
Monitors10% Televisions
10%
Computers, phones, printers, fax
15%DVD/VCR
Player, radios, HiFi sets
15%
E-Waste: Main Sources
Imports
Govt., public and private sector discards (over 70%)
PC retailers, manufacturers
Secondary market of old PCs
Individual Households
Why is Import a Main Source ? It is estimated that U.S. alone Exports 80% of its E-Waste to
China, India and Pakistan.
The developed countries industrialized and generate a lot of electronic waste.
The people in the developing country soon realized that they can extract a few components out of the electronic wastes and that may serve their need.
So, its (e-waste’s) demand in the market increased which in turn increased its exports at international market.
Informal processing of electronic waste in developing countries may cause serious health and pollution problems, though these countries are also most likely to reuse and repair electronic items.
This trade is also a defiance of certain international environment laws .
ProblemsE-waste is the most rapidly growing waste problem inthe world.
It is a crisis of not quantity alone but also a crisis bornfrom toxics ingredients, posing a threat to theoccupational health as well as the environment.
Rapid technology change, low initial cost, highobsolescence rate have resulted in a fast growingproblem around the globe.
Legal framework, proper collection system missing.
Imports regularly coming to the recycling markets.
Inhuman working conditions for recycling.
Average PC of approx. 31.5 kg
wt. contains:
7.24 kg - Plastics
1.98 kg - Lead
0.693g - Mercury
0.4095g - Arsenic
2.961g - Cadmium
1.98g - Chromium
9.92g - Barium
4.94g - Beryllium
Two million ObsoletePCs would mean:
14,427,000 kg
3,962,700 kg
1,386 kg
819 kg
5,922 kg
3,969 kg
19,845 kg
9,891 kg
E-Waste Hazards
Some More Problems
Pollution of Ground-Water
Acidification of soil
Air Pollution
E-Waste accounts for 40 percent of the lead and 75 percent of theheavy metals found in landfills
E-waste 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
E-waste Management:
E-waste management starts right from the point of production.
Sustainable Product Design ensures:
1. Toxics-free Products
2. 100% recyclability
3. Serviceability
4. Energy Efficient Products
Toxics Free Products:
Computer manufacturers should have a cradle-to-grave approach
Products should be made with minimum toxic-chemicals, resulting inconsequent toxic-free e-waste
Major Toxic Chemicals to be considered:
1. PVC
2. BFR
3. Antimony
4. Beryllium
Product Packaging Optimization for minimum Environmental Impact
100% recyclability:
Chemical Compliance of Global standards: PCV free+ BFR Free+ RoHScompliant products
Products should be designed with Antimony Free and Beryllium Freecomponents
Substance Toxicity Recyclability
PVC Carcinogen Limited
BFR Carcinogen Extremely tough
Antimony Carcinogen; organ Recyclable
failure
Beryllium Ulcers; skin Recyclable
Upgradeability & Serviceability
Design for Upgradability: Consumer should have the option of upgradingthe products: CPU, RAM, HDD …….etc
Design for Serviceability
Availability of Spare Parts, and Support over reasonable product life
The manufacturers must ensure the following so that the product life is long enough and disposal of IT products can be reduced:
Refurbishing v/s Recycling:
Although Refurbishing is a good option on paper, practically it has not
been very successful. Here’s why:
1. Technology changes in Hardware and Software render the old
computers non-refurbishable beyond a point
2. The refurbishing charges are relatively higher, acting as a deterrent to
the customer to refurbish
3. Original Software licensing is not clear for reused/refurbished
products
4. Prices of newer hardware keep on slashing down, prompting the
customer to buy a new-product, rather than go thru the hassle of
Energy Efficient Products:
Product should be Energy Star 5.0 compliant- 20% savings on bills and
20% lesser CO2 emissions in the air
Product should have energy Optimizing software features
Major components to consider:
1. Display: LCD displays save energy
2. Processor: New Generation processors are more energy efficient
Are we as consumers willing to pay a little extra premium to protect theenvironment
Steps for Sustainable e-waste handling:
For End-of-life Products:
Sensitize all stakeholders
Don’t auction-off; Hand it over to a responsible recycler/ Refurbisher
Do not dispose it as part of regular garbage or into land fills
Ensure 100% recyclability & safe disposal of your e-waste, thru duediligences.
For End-of-Use Products:
Hand me downs
Basel Convention
• It is an international treaty that was designed to reduce the movements of hazardous waste between nations, and specifically to prevent transfer of hazardous waste from developed to less developed countries.
• The Convention was opened for signature on 22 March 1989, and entered into force on 5 May 1992.
• The Convention is also intended to minimize the amount and toxicity of wastes generated, to ensure their environmentally sound management.
• The Convention states that illegal hazardous waste traffic is criminal but contains no enforcement provisions.
Need for Legal Framework
Ban on total imports of E-waste.
Domestic legal framework to address these gaps in import of E-Waste
Need to address safe disposal of domestic waste.
Tie recycling in with take-back product
responsibility.
