I discovered that there is a free online (.html) version of the bible of composting toilets, The Humanure Handbook. It can be found here.
Came across this neat little website by a bunch of Kiwis who helped out when the sewers went bad in Christchurch after the earthquakes. They impart some really good, practical advice on
how to build a composting toilet. Unlike a lot of sources, they discuss both pee and pee.
