A group of scientists at Penn State University is already working on making meals out of our feces and urine. This diet is not designed for regular people, but for astronauts, particularly those who may go on long-term space missions to destinations such as Mars.
The food was created utilizing anaerobic digestion, which is a method in which bacteria break down waste without the use of oxygen. To make methane, the first group of microorganisms is added to excrement and pee in this case.
The second group of microorganisms consumes methane. However, scientists are still working on creating this food, so we have to wait until we see astronauts eating it!
