How do I responsibly dispose of old zip disks?
Some archival repository libraries actually still get some use out of ZIP disks — though not for a long long time, since they require specialized equipment to read and have moving parts and thus are less than ideal for permanent storage solutions, but they do seem to hold up better than CDs for the medium term. I wouldn’t drive yourself crazy trying to find one that’s hard up for ZIP disks though, it’s not a widespread practice. Maybe call a couple of local libraries’ Special Collections or Archives, ask if they have any need of ZIP disks, and if you don’t get any hits within a couple minutes, shrug and go the Freecycle, environmentally sound disposal, or nonprofit organization that does need ’em route.
