E-Waste??

E-Waste: Waste of electronics / electrical goods that have reached their end of life

Electronic products often contain hazardous and toxic materials and should not be dumped with other wastes.

Along with China, India is largest importer of E-waste from developed countries like US, UK and Japan.

In India 90% of mobile equipment are imported.

The rate of e-waste generation is increasing by 10% every year.

0.8 million ton is contributed by India40 Million ton E-waste produced globally

Telecommunication Waste:

• Mobile phones• Telephones• Telephone exchanges Wireless Equipment cables and related scrap material• PC and TV

Electrical Waste:

• Switches• Relays• Connectors and related Scrap Material.

Electronic Waste:

• Electronic – metal waste• Printed Circuit Boards• E – Equipment and Machinery• IC• Sockets Connectors.

Cable Waste:

• PVC• Pre Insulated Copper and Aluminum Cable waste. 4

Issue and Challenge

s

Leaching of heavy metals from Landfills

and Incinerators

Exposure to workers &

communities

Unawareness (brand new

items are also kept in waste)

Less reuse

Collection

system

Legal framewo

Reusing and recycling

• Increase life span of product

Landfills

• Leaching problem (70% of Heavy metals in landfills are because of E-waste)

Incineration

• Fumes of Heavy metals released in atmosphere

• Municipal incinerators are giving dioxins

Ways of Treating E-Waste

9

Receipt of E-Waste

Sorting / Processing

Repairing

Upgrading

Testing

Refurbishing

Dismantaling

Component Recovery

Captive Use

Packing

Sale

Residual Disposal

Scarp

Environmentally-friendly disposal

Recovery of

Precious Material

Flow Sheet of Recyclers or Recycling Units

10

Recycling scenario

Takes useful COMPONENTS.

Ferrous metals sold to metal dealers.

Precious metals are recovered in a very dangerous and hazardous manner

Rest goes to land filling / water filling- disturbs ecological equilibrium

11

Recycling of CRT

workers manually dismantle most electronic equipment and sort out valuable commodities that are sold to various recyclers.

CRTs ready to be "crushed" for recycling.

12

The CRT crusher is completely self-contained in a transportable shipping container.

Crushed CRT glass, coated with lead, ready for processing by a lead smelter.

13

Other components from electronics are separated and sold as commodities to various recyclers.

14

How to Dispose E-waste

Donate working older equipment to schools colleges or government entities in need.

If PC are out of order then return it to the manufacturers. (HCL and Wipro in India has best take back service)

Send waste goods to authorised recycling facility for proper disposal.

15

Probable SolutionsNeed for stringent health standards and environmental protection laws in India,Extended producer responsibility,

Import of waste under license,

Producer-public-government cooperation,

Awareness program, following safer and efficient methods

Choosing safer technology and cleaner substitute,

Monitoring of compliance rules,

Reduction of waste at source,

Investment opportunity in waste management sector and

Recognition to the unorganised sector in India.
