If you are in San Francisco or the Silicon Valley, I’ve just found out about a group that recycles e-Waste, called GreenCitizen (can’t vouch, but it sounds pretty good). However, if you live elsewhere, or even if you do live in the Bay Area, many dumps or landfills will accept old electronics (yes, many are hazardous), or bleach, paint, or other toxic materials, often at no charge. Old CRT computer monitors are particularly toxic. But hey, if you have a MacBook Air, it’s completely recycleable (or you could just give it to me).
