Yes, the sawdust-compost toilet works, but is it a viable option? I'd like it to be, but whenever I come across something like this, I put myself into the imagined mind of whoever is the pop-tart of the day (say, the One Direction kids or the girl who hates streaming...can't think of her name). Are they going to go through with the sawdust-on-poo ritual? Probably not. Any solution that displaces the modern toilet will need to be at least as easy and thoughtless to operate as the current setup. I think a half-way solution is to outfit houses with a greywater circuit that could be used for the toilets. That would make a tremendous cut into the amount of drinking water that toilets are using.
