Maybe I'm wrong, but this seems to be a category that doesn't really need a black belt. The concepts behind these things are pretty simple, and so is the implementation, so I don't know what could be added that would be on the Black Belt level of difficulty.
This list seems to be a little light on the composting toilet side... Anyone have any ideas on how to add to that half on the list?
Bear in mind that there are lots of different dry toilet approaches. Here's a few from my new book on septic tank options and alternatives:
Self-contained composting systems
Remote composting systems
Electric drying systems
I'm not a fan of electric or chemical systems, but they do exist; hence their inclusion. Joseph Jenkins' lovable loo would be a remote composting system, and the outhouse would be a form of self-contained. These are just headings though for a wide range of different approaches. In terms of safety, I've read around this a lot for Irish planning submissions, and Joseph Jenkins' approach is actually the most solid. I bury my humanure in the garden under Comfrey, but that's not even as certain a method of sterilisation as JJ's thermophilic process.
Vis a vis grey water safety, I'd say that ensuring that the pipes are covered should be sufficient as long as you aren't close to groundwater resources.
In terms of urine reuse: Carol Steinfeld's Liquid Gold - the lore and logic of using urine to grow plants is a fun read. The other reference, which can be found online is Charles Sale's The Specialist. That's a lovely read.
