"A composting toilet is NOT an outhouse! It does not smell. It does not create pollution. Building a compost toilet is a good way to take refuse and turn it into a resource. A DIY composting toilet takes human waste, and dry material such as sawdust, crushed leaves, or wood ash and composts it with straw at a high heat to kill potential pathogens. At the end of the process you are left with sweet smelling, clean, and hygenic compost."
