There is nothing difficult about composting human waste. It does require a small amount of knowledge, and occasional monitoring. There is a link to an excellent article on the topic below, but in a nutshell…you need two bins. Use one only at a time. When the first one is full, start using the second one. When the second one is full, the contents of the first should be ready for the non-edible plants. When I put waste in my composter, I like to cover it with dry grass or leaves, but that is optional. It breaks down very quickly, and there is never any odor. It should NEVER get wet or slimy. If it’s getting wet, you need more dry material. It should never dry out. If it’s getting dry, add a little water. Please see the detailed article at compostingtoiletscanada.ca
