• Comprising of monitors, printers, hard drives, and circuit boards, the disposed computers are known as e-wastes.
• These e-wastes are not supposed to be thrown out along with the common household rubbish, as they contain highly toxic substance.
• The disposal of this hazardous waste requires atmost care and caution.
• It is estimated that, a single computer will contain approximately 2 kg of lead.
• The PCs are made up of a complex mixture of materials. This complex mixture makes these PCs very much difficult to recycle.
• You can safely dispose the e-waste by returning it to the manufacturer or donating the computers to a non-profit organization or transporting them to any professional waste disposal facility.
• The famous computer manufacturers offer a service to collect and transport the e-waste from your home to the recycling unit at their own cost.
• Professional waste disposal is same as the manufacturer’s schemes except the fact that you will have to pay for their service.
• A number of non-profit organizations collect electronic equipment including computers and printers, either for reuse or for de-manufacture and recycling. Recipients pay nothing for the equipment or buy it at a heavily discounted rate.

4.      Electronics often contain useful materials such as precious metals, glass, and plastics that should be recovered rather than buried in a landfill. 

5.      Precious metals are used in computer circuit boards and of course glass and plastics are used for manufacturing computer monitors.
