SOIL | A Good Sense of Humanure
If you have not read Joseph Jenkins excellent book The Humanure Handbook it’s time! Should be required reading. Even as a life-long composter, I am amazed by this method which uses zero water. There are no flies, no odors, and a valuable by-product is created, using simple things found on site!
This is an example of combining simple old methods with modern science instead of complicated, expensive, resource-wasting systems which are not sustainable.
