I come here to dump steel. I go to Copperhead Recycling on Indian School just east of 43rd Ave for everything else like cans because, unlike Liberty, Copperhead also takes plastic.
This place is pretty easy. You pull in to get weighed to dump your steel or go straight inside for cans, copper, and brass. I'd recommend a different recycler for aluminum or most anything else inside. Liberty has never paid as much for cans and aluminum as others.
