#e_Waste #ugcnet_paper1

- E- waste broadly covers waste from all electronic and electrical appliances and comprises items such as computers, mobile phones, televisions (TVs) and many other household consumer items.
- Waste electrical and electronic equipment (WEEE) contains various substances, which fall under the ‘hazardous’ and ‘non-hazardous’ categories.
- Iron and steel constitute about 50% of the WEEE followed by plastics (21%), non-ferrous metals (13%) and other constituents.
- Non-ferrous metals consist of metals like copper, aluminium and precious metals, e.g. silver, gold, platinum, palladium, etc.
- The presence of elements like lead, mercury, arsenic, cadmium, selenium and hexavalent chromium and flame retardants beyond threshold quantities in WEEE/e-waste classifies them as hazardous waste.
- E-waste may also contain precious metals such as gold, copper and nickel and rare materials of strategic value such as indium and palladium.




Basel convention and E-waste
- E-waste is categorized as hazardous waste due to the presence of toxic materials such as mercury, lead and brominated flame retardants are considered hazardous waste, according to the Basel Convention.
- The Basel Convention started to address e-waste issues since 2002 which include, among others, environmentally sound management; prevention of illegal traffic to developing countries and; building capacity around the globe to better manage e-waste.

The Global E-waste Monitor
- It is a collaborative effort between the International Telecommunication Union (ITU), the Sustainable Cycles (SCYCLE) Programme currently co-hosted by the United Nations University (UNU) and the United Nations Institute for Training and Research (UNITAR), and the International Solid Waste Association (ISWA).
