I had a question on where I could dump grass and all that stuff. My town has a dump, but for a commercial pass it cost $300 for every 1/2 cubic yard. The lady told me it was about the size of an average garbage can our town uses. I was thinking of buying a unit where you throw your grass in it and turn it a few times and it decomposed the materials. Does anyone know what that is called because i have seen it before.
