  •  Environmental issues related to the disposal of computer components. 12 ATAR




  • It's important to recycle and dispose correctly of all computer systems and electronics.
  • Many electronics contain harmful chemicals.
  • These chemicals can negatively affect our environment.
  • Recycling also benefits our economy, as less resources are used in gathering new materials since old materials are re-used.


The WRONG way

  • Do not simply throw your old computer or electronics in the household trash.
  • Giving old computers to exportation companies for developing nations isn't advised, as it's just passing the disposal problem on to a country or community that may not be able to afford correct disposal.


The RIGHT way

  • You should have your old computers and electronics collected by electronic waste recycling facilities
  • Advancements in these facilities now mean between 95% - 98% of the electronics can be recycled
