There is large Carbon footprint in IT production industry but that can be reduced by re-use and re-deployment of redundant IT equipments known as Computer Recycling.
Most of the environmental concerns with computers lie with the monitor, specifically its catode ray tube (CRT). On average, each color monitor contains 4 to 5 pounds of lead, considered hazardous waste when disposed of.
There are many hazardous materials in computers, including mercury, cadmium, and hexagonal Chromium (cause high blood pressure, iron-poor blood, liver disease, and nerve and brain damage in animals).
Computer Recycling problem is, after upgrading computer system, most organizations store their old computers, which serve as backup equipment in case newer computers break down. decision must be made at some point about disposal of this equipment as continuing to store old computers is often not a viable option, it eventually takes up a considerable amount of space. The least desirable option is to throw old computers into the bin. computer recycling comes into the fore in every possible scenario, not just the effect it has upon the environment, there is also the possibility of someone removing hard drives and recovering sensitive data.
This drives to the point that data on hard disks should be destroyed - before getting rid of the computer or hard disk in it. Computer recycling isn't always about the environment, but of company and national safety importance too.
From an environmental point of view, it is far better to recycle your computer at an official recycling centre than to dispose of it.
