Keynote
To Have Excretory Justice, We Have to Deal With Our Crap
Sarah Nahar
Sarah Nahar, M.Div (from Elkhart, Indiana Potawatomi traditional land) is a fifth year PhD student at Syracuse University. Her research focus is on the toilet, both the ritual and receptacle. She is matriculating concurrently at neighboring SUNY College of Environmental Science and Forestry in the Department of Environmental Studies. Other interests include working on dismantling the Doctrine of Discovery, community organizing, and capoeira.

Workshop: Exploring Design Principles for Equity & Justice in Urine Reclamation
Presented by: Marisa Manheim, Julia Dorr (University of Buffalo); Hayley Joyell Smith (PHLUSH); Tatiana Schreiber, Julia Cavicchi, Jamina Shupack (Rich Earth Institute)
In this interactive session, participants dove into urine separation design principles that emerged from a co-design workshop. In breakout discussions, participants reflected on their own work and experiences, sharing stories that reveal both the challenges and opportunities of applying these principles. By addressing the tensions between aspirations and real-world constraints, attendees offered insights to help refine the principles, ensuring their practical relevance across diverse contexts.
