Two words: Out House
That is effectively what a composting toilet is
That works.
I heard them referred to as "Rockefeller" toilets. Years ago, in the mid-1970s, I came across some wannabe Adirondack hippies. Their school bus vehicle ran on methane, served us cooked milk weed, etc, and they said they were waiting to get a Rockefeller [composting] toilet for the house.
Some Rockefeller was importing them, probably from Europe, at the time.
Also, the US Park Service (Clinton/Gore years) put in a bunch of solar powered (for the ventilation) ones, and managed to place the majority in the shade, leading to a raft of complaints about the stench.
