Yes, composting toilets are absolutely a solution for many countries but for some reason, they have never been well-supported enough to take hold. Many individual examples have been built that use locally available materials (like nets in a fishing village) but these are one-offs.
I saw some UN project but of course it was 20 toilets and 50,000 pages of reports and paperwork so that didn't really work out.
For much less money, Bill Gates could have produced some internationally accepted standard designs that could be open sourced for local production and even "flat pack" style for people to easily construct.
The guy has a great heart but this does look like a case of tech seeing everything as a technical problem.
