Plummer, Jeanine D.


The Bill & Melinda Gates Foundation initiated the Reinvent the Toilet Challenge (RTTC) in 2011. The RTTC aims to engineer a completely unique toilet to improve sanitation conditions in the world. The University of Colorado (CU) Boulder was 1 of 16 teams to receive a grant from the Bill & Melinda Gates Foundation. CU Boulder’s research team developed a waterless, self-contained toilet that can function completely off the grid through the utilization of concentrated solar power. The current design is not economically feasible. This MQP looked at the pros and cons of the current design, developed alternative designs, and made a design recommendation from researching successful implemented toilet designs and speaking with professionals in the sanitation technology field.
