The NEWgenerator 29 (a CRT from the University of South Florida) is a backend system that treats combined liquids and solids to recover nutrients, energy, and water. Two sanitation scenarios incorporating liquid treatment via the NEWgenerator, described in Watabe et al. , were modeled in the analysis: a baseline scenario utilizing grid electricity and an off-grid alternative scenario relying on photovoltaic electricity (Figure ). Both scenarios include a multi-unit flush toilet system connected to a screen and equalizer tank that feeds into the onsite NEWgenerator.
