If you are a school system, a city recycling center or a hospital, chances are that you have quantities of old scrap desktop computers – maybe several dumpsters full of them – that you would like to recycle.
What do they contain? We just found a terrific breakdown of the materials that old desktops contain – everything from iron to plastics to gold and other precious metals in the printed circuit boards and connectors. It was created by the now-defunct Microelectronics and Computer Technology Corporation (MCC) back in 1996. That year, you will recall, was in the golden age of desktop use.
Composition of typical Desktop Computer weighing ~27 kg.
According to MCC, "the following table presents the composition of a desktop computer plus a CRT screen in 1996. More than 80% of the weight consists of silica (glass), plastics, iron and aluminium. Precious and scarce materials account for only a small percentage of the total weight. Nevertheless, the concentration of such metals, e.g. gold, is higher in a desktop computer than found in naturally occurring mineral ore."

We’re pleased to share this chart with you. The more desktops you have, of course, the more precious metals you have on hand. Call us at 800-426-2344 to learn more.
