The European Space Agency has stated that one day human urine could be a ways that will benefit to build on the moon in asphalt.
In a study conducted, the organization said the researchers discovered that urea, the main bio-compound in the urine, would make the mixture more mixable for a lunar concrete, before it becomes more robust.
It showed that it would reduce the need for Earth to start supplies using only materials available on site for the basis of a moon or other structure.
A gloppy dust on the floor of the moon known as lunar regolith is one of the main materials for lunar concrete. ESA said that the urea that breaks hydrogen bindings and reduces fluid blends solubility would limit the water required for the recipe.
"The 1.5 liters (3.2 pints) of liquid waste a person generates daily, thanks to future lunar inhabitants, could be a promising space research by-product," he stated in a statement.
On Planet, urea is used by chemical and medicinal industries as an agricultural nutrient and a raw material.
The research co-author Marlies Arnhof said in an ESA announcement: "The idea is that urine from astronauts will basically be used on a potential lunar base, with slight changes to water contents. "It is very realistic and prevents rendering complex water treatment schemes in space much more difficult."
