A composting toilet is a type of toilet that separates urine and solids, and then composts the solids into a nutrient-rich soil amendment. Composting toilets are a sustainable alternative to traditional flush toilets, as they use no water and produce no wastewater. They are also a good option for people who live in remote areas or off-grid, as they do not require a connection to a sewer system.
