Where I live, nice but suburbs, I'd wrap in a plastic bag and then take to the town dump during my next visit there (within a couple days though). Same as we do with lobster shells. If I were on the water, depending on which water, I'd be inclined to share the scraps in the water, for the birds and any bottom dwellers, e.g. crabs. So long as not too much. I view it as biodegradable...so long as not too much.
