Many people in rural areas use composting toilets. It's a popular trend with those into self sustaining homesteads. The poop is generally going to be handled by a family member and mixed in with compost. After the bacteria in the compost breaks it down, it is then mixed in with other fertilizer and earth and used in greenhouses. The products grown in the greenhouse may be shared with neighbors or sold locally. Just adding for completely sake.
