Global Rich Earth Summit: Virtual
November 4-6, 2026 (Registration opens in June)
Mark your calendar for the 12th Annual Rich Earth Summit, the global gathering of practitioners, researchers, and advocates advancing urine diversion and source-separation systems for sustainable and just nutrient cycles. The Summit community is dedicated to reclaiming the value of the nutrients we excrete every day, transforming “waste” that pollutes waterways into resources that restore natural cycles and provide a sustainable fertilizer to farms.
The Rich Earth Summit explores a range of approaches—including urine diversion, compost toilets, and blackwater systems—and their benefits for protecting waterways, strengthening local food systems, building climate resilience, and expanding options for more affordable, adaptable housing.
