oh-'rilly? I dump them in the garbage with all the coke cans, newspapers and other garbage. I told my wife if she wants to recycle, go for it. Me, I 'm chunking it in the garbage.
I thought about the trash nazis and if they go on to "inspect" my trash then I'd just put the used bulbs in with the dog poop and rotten vegies.
When my neighbor needs to dispose of a used bulb, he puts it in a used McDonald’s cup, puts the lid back on, drives through the McDonald’s lot, and tosses the cup in their trash receptacle.
