Researching alternatives to flush loos, this looks likes the most interesting way forward both for its introduction to the microbiological science of composting (esp thermophilic bacteria), and Jenkins' relentless (humorous) attacks on fecophobes:
THE HUMANURE HANDBOOK, A Guide to Composting Human Manure, 3rd edition, by Joseph Jenkins - 255 pages, 19 photos, 42 tables and charts, 55 drawings, indexed.
Here is a link to a very simple explanation of how it works, with pix. http://www.saskwastereduction.ca/resources/Composting/comp-toilet.html
No more concessions to out-of-sight, out-of-mind. But it is hard not to still enjoy the thrill of the sucking jet loo emptying prowess of the toilets in big box stores. You feel as if you are a full participant in the Space Age. Another seductive illusion.
