Do you have a bunch of old batteries you don't know how to properly dispose of? Just take them to 3rLiving and they'll dispose of them for you. They'll do the same with old cell phones, ink cartridges, CDs and their cases, hand-held electronics, and Crayons.
All of these items may not be recyclable, per se, but there are programs for putting them to reuse. We're guessing 3rLiving has some ties into programs, which enables them to collect from the community and turn these items in in bulk. (thanks for the tip, amirrorcrackd!)
