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

Virtual ◆ Global

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, workshops, and networking with participants from around the world. Hear the latest research, learn lessons from pilot projects, and discover emerging technologies. Together, we’ll grow a more fertile future through completing the nutrient cycle!

Tickets are sold on a pay-what-you-can basis; please don't hesitate to reach out to julia@richearthinstitute.org to request a free virtual ticket.

This event is part of the 2026-2027 Rich Earth Summit Series: join online this fall, then continue on Cape Cod next spring April 7-9 for the in-person US Summit, deepening connections with watershed leaders and the ecological sanitation community.
