It took some digging, but I found a local recycler to take about 300 pounds of old computer parts, including five old CRT monitors and two printers that I'd been stashing for two decades or more simply because in my area there wasn't a responsible way to get rid of them. (Also some bits and pieces did get used occasionally for patches and repairs.)

As an example, the guys I found are American EWaste Recyclers; but you'll likely have to do some digging to find someone accessible in your own area.

Many computer manufacturers and some retail sellers claim to have recycling programs, but there usually are $tring$ attached that require you to pay for shipping, or that limit what they'll take. If your local government is on the ball, they may have a list of locally accessible "safe dumps" at least, and in some places the regular trash haulers may have special procedures.

All you have to do is find them.
