Reinvented Toilet Phase 4 To test the smoldering Reinvented Toilet prototype, and to support the subsequent design, build, and testing of multiple engineering validation units for foreign field testing.
Building on progress made to date for an energy efficient, cyclic-continuous household sanitation process based on liquid/solid separation or dewatering, in situ drying, smoldering and post smoldering catalytic conversion of solid excreta, and heat pasteurization of liquid waste, work during this phase will focus on continuing process simplification, improving reactor thermal performance, reducing mechanical complexity, improving robustness, learning about and addressing user behavior, identifying and engaging manufacturing and commercialization partners, and incorporating their input to reduce cost and productize our technology.
Mission
The goal is a commercially viable sanitation appliance that will be ready for commercial production development. This grant will be used to continue the development of an integrated household scale sanitation appliance – towards multiple site field studies and towards commercialization.Approach
This effort supports the BMGF strategy to improve sanitation in the developing world by developing “next-generation” toilets for households, communities and schools. Research or implementation partners: STeP and SankoyaFurther comments
