“What we’re using is a flushable pouch,” Yousef explained to The Daily Beast, while she was hopping from appointment to appointment in Boston one afternoon on a Lyft. “It’s a portable, evaporative, waterless toilet.”

The iThrone uses an innovative “self-flushing” technology by breaking the toilet down into two parts: a box-seat shell and a pouch with a polymer membrane that sits within a drum. The polymer membrane has twin powers: It’s able to evaporate the liquid contents of the pouch (our waste is about 95 percent water) while safely and odorlessly keeping the 5 percent of fecal matter contained.
