I have approx 50lbs each of calcium carbonate and portland cement from a few bags that had torn. I have no immediate use for either now and am wondering how I might dispose of them. I'll probably just but the cement in my garbage little by little for the weekly pickup, but I was thinking I could dump the limestone into my compost (I have approx 6-8 cubic yards of compost). Just want them both gone ASAP and thx.
