Economic Feasibility of Nutrient Recovery
Economic feasibility of nutrient harvesting from urine in South Africa - Part of VUNA project
The goal of this project is to identify and strengthen the drivers for sanitation. In the hopes of achieving 100% rural sanitation coverage, we are interested to know if urine-derived fertilizer production can be one such driver in the eThekwini Municipality, South Africa.
Specifically, we want to determine the conditions under which urine collection, transport and processing are attractive to both the municipality and the UD toilet user. We tested four different incentive (cash transfer) schemes in order to identify how much the UDDT owners’ would be willing to accept (WTA) to collect and transport urine. This had the dual purpose of increasing toilet use while generating a supply of nutrient-rich urine that was then converted into a valuable fertilizer.
We hope that by giving urine a value we will also give households an incentive to use and properly maintain household toilets, thus improving hygiene and reducing open defecation.

Behind the Data
"Behind The Data: The People Who Make Research Happen" is a short documentary, highlighting the work that was done in rural communities by the people who were instrumental in collecting and recording data for a sanitation-based research project. We aim to show the fundamental value of each person’s role in achieving the ultimate research objectives.
