Disposal of E- waste:

In land filling, trenches are made on the flat surfaces. Soil is excavated from the trenches and waste material is buried in it, which is covered by thick layer of soil. Now a day’s secure land filling are provided with some facilities like impervious liner made up of plastic or clay, leachate collection basin that collect and transfer the leachate to wastewater treatment plant. Environmental risk from land filling of e-waste cannot be neglected because the condition of land filling site are different from a native soil, particularly concerning the leaching behavior of metals.

It is controlled and complete combustion process, in which the waste material is burned in specially designed incinerators at a high temperature. Advantages of incineration of e-waste are the reduction of waste volume and utilization of the energy content of combustible materials. Disadvantages of incineration are the emission to air of substances escaping flue gas cleaning and the large amount of residue from gas cleaning and combustion.

Monitors and CRT, keyboards, laptops, modems, telephone bards, hard drives, floppy drives, compact disk, mobiles, fax machines, printers, CPUs, memory chips, connecting wires and cables can be recycled. Recycling involves dismantling and recovery of valuable materials. Recycling is the best possible option for the management of e- waste because the existing dumping grounds in India are full and overflowing beyond capacity and it is difficult to get new dumping sites due to Scarcity of land.

It is commonly used for electronic equipments like computers, cell phones etc. It constitutes direct second hand use or use after slight modification to the original functioning equipment. This method also reduces the volume of e-waste generation.
