The Humanure Handbook presents in Ch. 4 a brief description of Asian recycling of humanure, with reference to Farmers of Forty Centuries by F. H. King. This is a great read, and now available online at: https://www.soilandhealth.org/01aglibrary/010122king/ffc.html
My wife and I are avid gardeners. Composting humanure is not only a means to save water, but also a way to improve soil fertility by returning organic materials to the land. I found it instructive to read in Farmers of Forty Centuries detailed descriptions of humanure recycling that worked well during many lifetimes.
