What does Fanime do with badges not picked up?

What does Fanime do with all of the badges that weren't picked up for the con? I think there were some pre-reg badges not picked up or something the past few years.

At the end, they pile them up into a gigantic monument and do a ceremonial dance around them, summoning the spirits and power of all those who didn't show up to give them the strength to do the next year's convention.

Or, maybe they just throw them away?

One (or more) of those answers may or may not be correct. ;)
