Ground-up tires?

There are a fair amount of knowledgeable (and, well, imaginative) folks
here, and I'm looking for help.

A tire recycler in Gulfport. MS got Katrina'ed, and there are tires out
the wazoo (that's a whole bunch of tires) on his property. Long story
short is that there are tires, a problem with them, and I figured good
ol' ROFF is as good a place as any to ask if anyone has any ideas,
contacts, wants to Google beyond what we've done, or ???

And for the record, I have no interest in the problem directly beyond
that as a concerned citizen. And to go even further, if someone knows
something that results in money being made, and I somehow wind up being
able to direct any of it, it goes to charity.

Thanks in advance, and all ideas welcome,
R
