A toilet revolution is set to bring much-needed change when it comes to human waste. Each day, a single person produces one liter of urine and 200 grams of feces. In many places, feces is flushed down the toilet using around six liters of water, generating millions of tons of waste.
Globally, the issue presents major health and environmental challenges, because this waste has to be processed and disposed of. Reducing toilets’ immense water consumption is the focus of a good deal of research. The goal is almost completely dry toilets.
