Computer Recycling

Computer recycling, electronic recycling or e-waste recycling is the disassembly and separation of components and raw materials of waste electronics.


Electronic recycling can be challenging because discarded electronic products are complex devices manufactured from varying proportions of glass, metal, electronic boards and plastic. Then, these materials needs to be processed and separated into clean boxes that can be used to make new products.


A first step to recycle a computer is to collect and to sort the computers by item type. After sorting, the computer parts can be tested for possibility of reuse. If is still not functional or is in a fairly bad working condition, and the parts are superannuated, the computer is likely to be recycled.


The next step is manual disassembly. The basic computer components that are disassembled generally include: speakers, sound and graphic cards, circuit board, DVD drives, hard disks, and keyboard among other parts. For example, a Computer System Unit (CSU) to be recycled, it needs to be unscrewed by the computer case and computer chassis, then, by turn, to remove its components (optical drive, fan, hard disk drive, motherboard, expansion slots, connectors, power supply, fan, CPU).

Then, it comes data destruction. Step, in which all hard drives and processors will be damaged to ensure that all the data in the hard drive will not be used anymore.The last step is to separate all components into material composition. For instance, plastic shells of the computers, metals, circuit boards and wires are broken down separately.
