Advancing circular sanitation for clean water and sustainable agriculture. Together, we can pee the change!

The 2026 Rich Earth Summit is the 12th annual gathering for urine diversion, compost toilets, and other source separation systems--advancing sustainable and equitable nutrient cycles. The Summit explores how nutrients in human “waste” can be reclaimed as a valuable resource for farms instead of becoming costly watershed pollutants. The Rich Earth Summit brings together a growing global community of researchers, nonprofit organizations, entrepreneurs, farmers, educators, engineers, municipal leaders, policymakers, and advocates.

The Global Virtual Summit will feature three days of virtual presentations, panel discussions, and interactive breakouts to connect with other participants. 46 presenters will share research, storytelling projects, economic strategies, and pilot projects from around the world. Conservation biologist Joe Roman will present the keynote “Eat, Poop, Die: How Animals Make Our World," based on his book of the same title. View the full Summit schedule and presentation details . 

Together, we can grow a more fertile future through completing the nutrient cycle!
