ABSTRACT
As a result of industrialization and ever increasing demand of electronic products in daily life E-waste is
generated at a much faster rate. E-waste is growing in India at the rate of 10%.The condition in India is
much worse because about 80 percent of the e-waste generated in the US is exported to India, China and
Pakistan under the name of charity. Current data indicate that the total domestic e-waste generation
including imports is around 382979 MT, however waste available for recycling and actually recycled are
144143 MT and 19000 MT, respectively in which recycling by non-formal and formal sector are 95% and
5%, respectively. The paper discusses various treatment technologies used for treating E-waste along with
recovery & reuse options. It also provides information regarding legislative measures that have been
taken to deal with E-waste globally and in India.
Keywords: Industrialization, E-Waste, Recycling, Non-Formal and Formal Sector
INTRODUCTION
E-waste are going to become a great challenge for environmentalists and technologists as the rate of
growth is much higher than the rate it is disposed, reused or recycled. There is an urgent need for
improvement in E-waste management plan. There are new practices being adopted globally that will lead
to the sustainable management of e-waste such as: design for environment, innovative product design,
extended producer responsibility, standards and labeling, and recycling and remanufacturing. To tackle
the future environmental problems that will eventually occur from improper management of e-waste,
many developed countries and organizations have drafted legislation to address the reuse and recycling
material recovered from EEE to reduce the amount of toxic materials disposed in landfills. Recycling of
e-waste is important, because it allows the recovery of valuable material and reduces the amount of waste
requiring disposal Gupta (2009). Recycling of e-wastes is carried out by the formal and non-formal
sectors for the recovery of valuables and disposing of wastes. In India, participation for recycling of e-
wastes by non-formal sector is about 95% and that of formal sector is 5%. Various government
organization and research centers are trying to achieve an integrated process for the recovery and
separation of metals from the e-wastes including pretreatment process like cutting, shredding, grinding,
air classification followed by leaching and solvent extraction process. The processes have also been
proposed for the recovery of precious metals such as gold. Researchers and industrialists are integrating
together to parleys small scale e-waste recycling industries into large scale industries.
E-Waste Management
The story of current Indian e-waste management is different from the worldwide practices. In India, rag
pickers pay some amount to the customer from whom they are collecting the waste and on the other hand,
recycling fee is charged from customers to manage waste effectively in developed countries Kumar et al.,
(2011). E-waste is mostly handled by unskilled workers and they do not take proper safety measures.
Moreover, proper place is not used for e-waste handling. The operations to treat e-waste are carried out
within the cities and slums. At some places, operations are carried out without proper ventilation and
lighting facilities. Recycling and disposal is not properly done due to lack of appropriate technology Wath
