"I might use it again" (46 percent) - well, I might
Throwing USB cables into your wastebin because you can't think of anything better to do with them - ok, that is e-waste.
Putting the same cable into my Useful Box is now hoarding and *also* e-waste, because what, I won't get around to using that cable for anything else for, oh, 6 months? 12 months? 24 months? Spotted one that was some 5 years old last week - because I'd used up all the newer ones that had landed on top. Maybe its time will come soon, maybe not so soon.
Yes, I have some Android 'phones (two, IIRC) that haven't been switched on for about 3 years now. Is this hoarding? Well, haven't been out of the UK in all that time, so no need for a "don't really care about it" 'phone each. Better to hold onto them or is that Bad Hoarding? When the batteries die, fine, no use keeping them around. Meanwhile, there are weird ideas floating around (glue one behind a mirror for a Halloween trick?) - in all honesty, good chance I won't get around to that, but if enthusiasm strikes better to be able to reuse than to go out and get something new (even if just second hand and "new to me").
Recycling valuable materials is definitely a Good Thing, but they are just going to have to wait until I pop my clogs (and everyone left around has picked over the piles), at which point the "hoarded" stuff will go into the proper WEEE streams.
