E-Cycling Central provides a state-by-state look at electronics recyclers, as well as a rather minimalist list of links to other recycling resources.
Earth 911 offers a searchable by item and location database that covers just about the whole gamut of home, personal, business and other materials, helping you locate drop-off sites near you.
A good point, again from a reader, to bear in mind is that recycle should be used in its broadest sense -- many of our computers, printers and other electronic discards. can be re-conditioned and re-used, donated or distributed to groups, organizations and individuals in need of them. The sites above can help you find re-use and re-conditioning opportunities as well.
You might also want to check out DonateIT for a dedicated and interesting look at how discarded tech can become effective fund-raising items.
DonateIT, by the way, recommends DBAN, a free open source data destroyware (DBAN = "Darik's Boot and Nuke") to clean your disks of business data with confidence.
I'd still feel more confident physically removing and destroying the storage device, but that confidence is accompanied by a nagging sense of hyper-caution causing wasted tech that DBAN might also be able to obliterated.
Thanks to everyone who wrote in on this topic -- love to hear more, especially if anybody's got any "oops we recycled the confidential financials" stories.
