  • Descriptive Overview
    Vuna means "harvest" in isiZulu, the language of the Zulu people. The system is a scalable urine processing and resource recovery system. VUNA originated as a research project which endeavored to find a suitable use for the urine collected in dry toilets in the city of Durban, South Africa. VUNA further developed between Eawag, eThekwini Municipality (greater Durban) and additional partner organizations. The technology to recover nutrients – or rather "harvest" them – has been well established. In 2016, the company Vuna Ltd was founded based on the outcomes of this research project and sells the Aurin fertlizer from urine.
