Perhaps this sort of project could be done to improve the image of bitcoin, to have one less argument against it out there in the world. IT would be a non-profit I guess, you could call it minecycle or something like that. Would be good pr.
Yeah good idea, but to create a non profit organization you need some funds. You would probably have to gather those through donations. Most people would just throw their miners to a bin, or keep as a reminder, instead of paying you to recycle.
