When Possible, Donate
This makes it very easy for current owners: Look for local organizations that want usable electronics for their facilities. Of course, the devices need to be in usable condition and not too old to be a fitting donation, but it’s an option that keeps them out of the trash for as long as possible, and that’s a plus. Oh, and always do a wipe and factory reset of the device before giving it away – that applies to any e-waste step.
