Piss soap is made entirely out of human activity waste materials, namely wood ashes, used cooking oil and urine. All these materials can be easily gathered locally from a urban environment. The gathering of material and production of the Piss Soap is locally implemented and redistributed to the public cleaning services as well as the inhabitants. Piss soap has a regenerative impact in our cities, allowing to transform in a creative and useful way, wastes that our cities congregate.
