About us

How the VUNA project with the city of Durban in South Africa became Vuna GmbH.

Vuna means "harvest" in isiZulu, the Zulu language of South Africa. VUNA originated as a project in 2010, when the city of Durban (South Africa) sought for a use for large quantities of separately collected urine. VUNA subsequently evolved between Eawag, eThekwini (Greater Durban), and other partner organizations. The VUNA urine recycling technology for nutrient recovery—or "harvesting"—from urine has proven successful. In 2016, the former VUNA project became Vuna GmbH.
