Computer Recycling and Repurposing
Computer recycling is reuse or recycling computers. both used to find other materials that allow for the safe extraction of the support materials to be reused in other products.
Reasons for recycling
if treated properly Old computers are a valuable source for secondary raw materials; But they are a source of toxins and carcinogens if not treated properly,. Computer recycling has resulted in rapidly growing surplus computer parts around the world due to rapid technological changes, and low initial cost,
Will be ready late-life management in each of the next few years according to U.S. Environmental Protection Agency, an estimated 30 to 40 million surplus in PCs, which classify under the term “hazardous household waste”.
The U.S. National Security Council estimates that 75% of all personal computers sold today have electronic surplus. before technical solutions can be applied, but in many cases the legal framework, a collection system, logistics, and other services the technical solutions are available to be implemented.
In the future production of many materials used in the development of computer hardware can be recovered in the recycling process to be used. – All present in large numbers in computers – can reduce the cost of building new systems, such as the reuse of tin, silicon, iron, aluminum, and various plastics. In addition, there is another ingredient that is valuable from the components often contain copper, gold,
Although the former computer components and elements of valuable substances suitable for reclamation, namely tin, copper, and gold. But computer recycling also contain many toxic substances such as dioxins, polychlorinated biphenyls (PCBs), cadmium, chromium, radioactive isotopes, and mercury.
Through incineration air pollution may occur due to the circuit board in sufficient numbers that contain lead-tin solder may be dissolved arrives into the ground. In addition, the processing required to retrieve an important material (including incineration and acid treatments), produces, and synthesize more toxic by products.
An ordinary computer monitor may contain more than 6% by weight, most of the glass cathode ray tube (CRT). A typical 15-inch computer monitor can contain 1.5 pounds of lead, but other monitors that have been estimated to have up to 8 pounds of lead.
A major concern for computer recycling is a waste exports to countries with environmental standards are lower. With a little lax regulations companies seeking cost-effective in the short term, can help pay transportation costs for a large number of worthless “commodities”. to sell old computers to developing countries. This is usually the reason that the majority of laptop surplus transferred to developing countries as a high value and waste can be reused, for example laptops, computers, and components (eg, RAM) Broken monitors, obsolete circuit boards, and short circuit of transistors that are difficult to place in the former electronic container load.
