How Do I dispose off my old computer in an eco- friendly manner?
Many communities have collection days for unwanted electronics which are then taken apart and parts recycled or disposed of properly. For your community, maybe a call to the public works or city hall would connect you with a drop off day or place. The garbage collection company might be able to tell you. NOTE: about donation. Really old computers and equipment is NOT wanted by any charitable agency. I work for one and all that junk electronics just creates a problem because now we have to dispose of them. Things that are a few years out of date are usually welcome.
You can donate it to non-profits, a friend, or other places. You can also call the company that created the computer and see if they offer re-collection of old systems (if it’s a Compaq, that’s HP now; Packard-Bell is HP; eMachines is also Gateway). Since you can’t get rid of it in a landfill because its components have lead and mercury, call your city administration building (city hall or 311 in most areas) to ask them if the city or county offers electronics recycling programs.
