Composting Toilet Systems

Composting toilets convert human waste into nutrient-rich fertilizer for nonfood plants, rather than mixing the waste with potable water and flushing it down the drain. Advantages of composting toilets include dramatic reductions in water use, reduced groundwater pollution or sewage-treatment impacts, resilience (ability to operate during water shortages), and recycling of nutrients. Some composting chambers can be used with microflush and foam-flush toilets, though most use no water.
