Human urine can be an important ingredient to build concrete in the moon, according to the European Space Agency (ESA).
In a study published in the Journal of Cleaner Production, urine is a potential admixture for lunar geopolymers.
In addition, this is also practical as scientists seek to minimize the components they bring from earth.
Urea, the most abundant component in the urine, can make “lunar concrete” ore malleable before hardens into its sturdy final form
ESA said the main ingredient of the “lunar concrete” is lunar regolith, a powdery soil found on the moon’s surface.
Further, the agency said urea can limit the amount of water necessary in the recipe, as it can break hydrogen bonds and reduce the viscosity of fluid mixtures.
An individual can produce 1.5 liters of liquid waste that can be a by-product for space exploration.
Meanwhile, here on Earth, urea is used as an industrial fertilizer and a raw material by chemical and medical companies.
“The hope is that astronaut urine could be essentially used as it is on a future lunar base,” Marlies Arnhof said.
“This is very practical and avoids the need to further complicate the sophisticated water recycling systems in space.”
