When it really is time to get rid of your computer, then you should know that there are recycling programs available.
I have worked in offices in New York City, a place which has very strict trash separation laws for recycling purposes, and at each of these offices I found that at least one old keyboard, monitor, and CPU tower. No one seems to know what to do with these old machine parts, but a simple search on the Internet should result in a program that welcomes the donation of your old computers or there parts. The fact is that up to ninety five percent of computer parts should be fully recyclable, even potentially toxic monitors.
In the United States, there are programs that have been set up so that your old computers can be recycled. Old computers and even broken computers are either given to families who cannot afford to buy. If the computers cannot be fixed, then they are recycled appropriately. This usually involves breaking the computer apart and reassembling the working parts to make a brand new computer. Parts that are too old or cannot be fixed are sent to places which can deal with them in the proper ways. Computer monitors can be sent to China, for example, where factories have the technology in place to re-smelt the monitor tube to make a new one.
Computer monitors contain toxic substances and should never be thrown away with the usual rubbish collection. Increasing numbers of localities are banning computers from land fills for fear or lead or other contaminants entering ground water supplies. This is because the monitors, like television screens, contain cathode ray tubes or CRTs that contain a substantial amount of lead. However, a few companies that have the technology and processes to separate the lead from the glass used in monitors, enabling the recycling of cathode ray tubes.
CD-ROMs and floppy discs are also a source of pollution for our planet. The burning of discs in incinerators will release toxic emissions, and discs in land fills can do the same. The simplest way to recycle unused discs is to erase and reformat them for re-use. One company in the United States buys unsold software discs to recycle in this way. As for used consumer discs, the recycling process is a little more complex. To fully protect them against data and purity corruption, these discs must be broken down, mixed with new materials, and remade.
Consumer and government pressure is putting more pressure on computer manufacturers to create recyclable machines and parts. Several design considerations can improve the way these parts can be recycled. One is to minimize the plastic material composition, and to use similar classes of plastics that have the same recycling method, which will aid to facilitate sorting. Another is to avoid resins, paints, and plastics that contain no toxic compounds or heavy metals. Advances in chemical and materials engineering are making this increasingly possible. Naturally, by using recycled materials in their products, computer manufacturers are actually supporting the recycling industry and encouraging its continuation.
