The VUNA project was led by Eawag research between 2010 and 2015 with the goal to recover nutrients from urine and empower farmers in South Africa.

VUNA stands for Valorisation of Urine Nutrients in Africa, and was the name of the research project. In isiZulu, the word 'vuna' means harvest. 

Vuna GmbH, our sister company, was founded in 2016 leading the way in the installation of decentralised sanitation solutions in general. 

VunaNexus AG was created in 2022, to focus solely on the urine treatment technology and fertiliser production.
