Looking for somewhere or someone that could use a lot of styrofoam sheets. slightly wedge in design?

The company I work for just had to re-package some product and now the Styrofoam sheets that were used before will not fit, I can't stand to fill the dumpster with it/ would like to see it recycled in some way. The sheets are 17-3/4 X 33-3/4 X 1/2" on the thin side and 1-10/16 on the thickest side. The company is in southern Ohio would rather give them away to someone that can use them instead of throwing them away. I have already contacted the local school administration and local extention agency for the 4-H groups. These were used, but are still in pretty good shape, and like I said there are a lot of them and would have to be picked up by truck or something.
