 It is a controlled and complete combustion process, in which
the waste material is burned in specially designed incinerators at a
high temperature (900-1000oC).
 Advantage of incineration of e-waste is the reduction of waste
volume and the Utilization of the energy content of combustible
materials. Some plants remove iron from the slag for recycling. By
incineration some environmentally hazardous organic substances are
converted into less hazardous compounds.
 Disadvantage of incineration are the emission to air of substances
escaping flue gas cleaning and the large amount of residues from gas
cleaning and combustion. e-waste incineration plants contribute
significantly to the annual emissions of cadmium and mercury. In
addition, heavy metals not emitted into the atmosphere are transferred

It constitutes direct second hand use or use after
slight modifications to the original functioning
equipment. It is commonly used for electronic
equipments like computers, cell phones etc. Inkjet
cartridge is also used after refilling. This method
also reduces the volume of e-waste generation.
We can use above mentioned methods for
treatment and disposal of e-waste. The better
option is to avoid its generation. To achieve this,
buy back of old electronic equipments shall be
made mandatory. Large companies should purchase
the used equipments back from the customers and
ensure proper treatment and disposal of e-waste
by authorized processes. This can considerably

 In landfilling, trenches are made on the flat surfaces. Soil is
excavated from the trenches and waste material is buried in it, which
is covered by a thick layer of soil. Modern techniques like secure
landfill are provided with some facilities like, impervious liner made up
of plastic or clay, leachate collection basin that collects and transfer
the leachate to wastewater treatment plant. The degradation
processes in landfills are very complicated and run over a wide time
span.
 The environmental risks from landfilling of e-waste cannot be
neglected because the conditions in a landfill site are different from a
native soil, particularly concerning the leaching behavior of metals.
Mercury, cadmium and lead are the most toxic leachates. Lead has
been found to leach from broken lead-containing glass, such as the
cone glass of cathode ray tubes from TVs and monitors. Cadmium also
leaches into soil and ground water. In addition, it is known that
cadmium and mercury are emitted in diffuse form or via the landfill
gas combustion plant. Landfills are also prone to uncontrolled fires,
