Water-free flushable toilet is a toilet technology that can flush toilets without a water source. It uses the collected urine to flush feaces. This technology solves the problems of odor and infrequency of urination. It uses a special liquid consumable to keep fresh urine in a sterile urea state without turning into ammonia and releasing ammonia gas. Flushing urine can be recycled, flushing stool can be deodorized, sterilized, crushed, liquefied and discharged, and the total amount of flushing fluid can be automatically controlled and balanced. Emissions are reduced, rendered harmless and can be utilized as resources. The system includes occupancy identification, urine and feces identification, solid-liquid separation, lighting, ventilation, flushing, and presence or absence display to achieve fully intelligent automatic control.
