My puzzlement exactly.
We have e-waste at our town transfer station. So far, I've had one LED bulb fail (it failed a 8' drop onto concrete). I just put the remains (which continued to throw light, but minus the diffusion of the envelope) into the trash. As I understand it, e-waste is for anything with potentially recoverable resources (e.g. copper in motor windings, gold from PC boards) so putting failed LEDs in e-waste seems more... aspirational than anything else. I was hoping someone would have a decent resource explaining why they should go there anyway. Glad to find out I'm wrong about something.
