Japan has some of these, as well as a ton of European places.  When I was in Greece it was like that, Turkey and Italy as well.  Japan and Korea(good version) are also places that do this.  Some of those places had toilets that could take it, but they still wanted us to do that.  You just wipe, put it in the trashcan in the stall with you(usually a scented bag in it) and they take it out daily.  If you have a good diet, then you aren't going to be putting chocolate pudding wiped from your arse into the can.
