Content - Summary

This library entry contains background documents for a grant that Kai Udert is leading and which is funded by the Bill and Melinda Gates Foundation.

Further information and a discussion is available on the SuSanA discussion Forum, see link below.

Short description of the project:

By recovering nutrients from urine in small decentralised reactors, VUNA wants to develop a dry sanitation system, which is affordable for the poor, produces a valuable fertilizer, promotes entrepreneurship and reduces pollution of water resources.

In this collaborative project, the Swiss Federal Institute of Aquatic Science and Technology (Eawag), eThekwini Water and Sanitation (EWS) in Durban, the University of KwaZulu-Natal (UKZN), and the Swiss Institutes of Technology Zurich and Lausanne (ETHZ and EPFL) work together to focus on three important aspects:
1. reactor technology
2. network management
3. socio-economic boundaries

Documents available for download: Please check the project website (link below) to access the latest publications from this project.
