|Making sanitation pay for subsistence farmers. The EZPZ leverages on the existing success of latrine adoption by our partner, IDE Cambodia, by acting as a stepping stone toward a complete sanitation solution. The first product we aim to launch is the EZ*PZ, a stand-alone or latrine add-on that captures and converts liquid human waste into safe fertilizer.|
Project Launched: Beta Launch December 2011
Current Status: Preparing for trial launch in Cambodia and pursuing funding
Team: Peter Mulligan, Cara Silver, Anne Stake, John Thomas, Mira Wijayanti
Everyday, Cambodian subsistence farmers must choose between providing their family’s next meal or preventing their next sickness. With such low crop yields due to underfertilization, the next meal almost always wins. Using human waste to fertilize their crops is necessary for their survival, yet its very use leads to sickness, inflicting diarrhea on 20% of Cambodian children under 5 and leading to productivity losses totaling 7% of the country’s GDP.
In this cycle of poverty and disease, low agricultural yields and poor sanitation have been viewed as separate challenges by donor agencies and NGOs. Yet Cambodian subsistence farmers have discovered the linkage between sanitation and agriculture: human waste as fertilizer. Team EZ*PZ promotes changing unsanitary practices into safe ones, by providing products that help farmers harvest clean value from their waste.
The EZPZ leverages on the existing success of latrine adoption by our partner, IDE Cambodia, by acting as a stepping stone toward a complete sanitation solution. The first product we aim to launch is the EZ*PZ, a stand-alone or latrine add-on that captures and converts liquid human waste into safe fertilizer. It:
· Separates urine from feces and blackwater, providing greater opportunity for management
· Provides farming households with ~$40 of fertilizer value each year
· Builds value behind sanitary waste management
Team EZ*PZ plans to develop an enterprise that delivers clean value from waste for rural Cambodian households. We envision a world where sanitation pays – for farmers, for entrepreneurs, and for the Cambodian people.
What’s Happening Now?
Upon the completion of Extreme, our team received funding from Social E.Lab to move forward with our project. John Thomas traveled to Cambodia with new team members, Cara Silver and Anne Stake from July to September 2011 with support from Mira Wijayanti and Pete Mulligan, who are completing their studies at Stanford. During this trip, we conducted a small-scale pilot to gain additional feedback enabling us to refine our initial prototype. We also established contact with local manufacturers and distributors. As we complete the final preparations for the beta launch in December 2011, we are excited for our products to reach hundreds of Cambodian subsistence farmers.
