RICH EARTH
SUMMIT
2025

Hosted by:
Rich Earth Institute
Virtual: November 12-14
Hosted via Zoom
Open through July 1, 2025
Join the global conversation about reclaiming our "waste" as resource!
The Rich Earth Summit, hosted by Rich Earth Institute, is the global event dedicated to advancing urine reclamation and source separation–to create sustainable and just nutrient cycles. This gathering brings together researchers, practitioners, and advocates to share knowledge, showcase innovative projects, and foster collaboration. Join us at the 11th annual Summit on November 12-14, 2025 – a golden opportunity to explore the transformative power of peecycling. Together, we can pee the change!
The 2025 Summit will be a hybrid event. The virtual component (Nov 12-14) will feature themed panels, roundtable discussions, and interactive sessions. The in-person component (Oct 15-17) will be hosted in Cape Cod, Massachusetts at MASSTC’s Clean Water Center to spotlight local nutrient pollution challenges and opportunities for action.


Separating human waste at the source rather than combining it into one, dilute wastewater stream can enable tight, efficient cycles of resource recovery. Source separation increases the value of the resource: contamination and dilution are minimized while processing is simplified.
Why Source Separation?
Urine, rich in essential plant nutrients, can be reclaimed as a sustainable fertilizer, preventing nutrient pollution in watersheds and conserving water resources. This process, known as “peecycling,” can be a vital strategy for both nutrient management and sustainable sanitation solutions.
Why Urine Diversion?
About Rich Earth Institute
The Rich Earth Institute advances food nutrient cycling through research, demonstration, and education. Based in Vermont, Rich Earth’s flagship program is the first and largest community-scale urine recycling program in the US. Rich Earth serves as a knowledge hub for ecological sanitation researchers and practitioners around the world.
