Hey TBR!
Once a year our city has a river sweep event where the community comes out and helps clean the banks of the Cuyahoga
river. Our co-op is situated along that river, so we collect them through the year, and they let us add to their tire dumpster. From their, I think it gets recycled into playground mulch or something.
Short answer, find some neighborhood clean up event and see if they will partner up with you. Hope that helps!
P.S. I loved your ACE's workshop at NE!
Always,
