Used in glass panels & gaskets in computer monitors
Used in soldering in printed circuit boards & other components
Attacks nervous system, Kidneys & reproduction system & endocrine gland
Impedes Brain development among children
Used in thermostat sensors, relays, switches, medical equipment, mobile phones, lamps & in batteries
Now a days also used in flat panel displays replacing cathode tubes
It is estimated that 22% of yearly world consumption of mercury is used in electrical & electronic equipment
Cause damage to brain, kidneys & foetus (Developing foetus is highly vulnerable to mercury exposure)
When spread in water forms methyl mercury, which bio accumulates through food chain & spread minamata disease
Major Sources – Burning coal, Batteries, Thermometer, Barometer, Electric switches and relays, Cosmetics & pharmaceuticals, Lamps & dental amalgam
Used as corrosion protector of untreated & galvanised steel plates & as a hardner for steel housing plastics including PVC
Largest volume of plastics (26%) used in electronics is PVC, used as cables & in housing computers (Dioxin & Furan is released when PVC is burned – Highly carcinogenic & toxic)
Chromium VI can cause damage to DNA
Occurs in SMD chip resistors, infra-red detectors & semiconductor chips
Some older cathode ray tubes also contain cadmium
Accumulates in body, especially in kidneys
Brominated Flame Retardant
Used in plastic housing of electronic equipment & in circuit boards to prevent flammability
A soft silvery white metal, used in computers in front panel of CRT, to protect users from radiation
Exposure to barium can cause brain swelling, muscle weakness, damage to heart, spleen & liver
Commonly found on motherboards & finger clips
Used as a copper beryllium alloy to strengthen connectors & tinyplugs while maintaining electrical conductivity
Exposure can cause lung cancer, skin diseases as poor wound healing & wart like bumps
Found in plastic printer cartridges, containing black & printed toners
Contains heavy metals & causes respiratory problems
An inorganic chemical compound applied as a coat on interior of CRT plates
Phosphor coating on cathode ray tubes contain heavy metals such as cadmium & other rare earth metals (Zinc, vanadium etc.)
Serious hazard for those who dismantle CRT by hands
E Waste Recycling
So far, throw money & ship to developing country to dump
ewaste has been shipped to developing countries where this poses dangers as it is handled by informal sector.
(Management, Handling and Trans Boundary Movement) Rules, 2008
Import of such wastes for disposal is not permitted except for recycling by the registered units only and with the permission of the Ministry of Environment and Forests and/or Directorate General of Foreign Trade.
For effective implementation of provisions related to import and export, a coordination committee including representatives from revenue department, DGFT, ministry of shipping, Central Pollution Control Board has been constituted.
This committee has been working to sensitize the customs authorities regarding enforcement of these rules in order to check illegal import of ewaste into the country.
(Management and Handling) Rules, 2011
The concept of extended producer responsibility has been enshrined in these rules to make it a mandatory activity for the manufacturers of electronic and electrical equipments.
Under this the producers are responsible for collection of ewaste generated from the end of life of their products by setting up collection centers. The concept originated in Switzerland
Ewaste recycling can be undertaken only in authorized facilities. Government has started a scheme to provide financial assistance for setting up of treatment plants in PPP mode.
