After a scientific study that could represent a revolution in the future of construction, researchers have found a way to make bricks using human urine.
The researchers, from the University of Cape Town, South Africa, succeeded in preparing the building blocks with a natural process called "bacterial carbon deposition".
In this process bacteria grow in a sandy environment added to the urine, producing an enzyme called "Uraz".
This enzyme works to break down urea in the urine, producing calcium carbonate that turns the sand into cohesive lumps.
The hardness of molds that are directly proportional to the length of bacterial growth in their environment can be controlled.
The whole process can occur at room temperature, making it environmentally friendly and consistent with the goals of maintaining the Earth's temperature.
The only challenge they have to overcome is to convince customers to build their homes with bricks made of human urine.
"If a customer wants a stronger block of limestone by 40 percent, you have to allow the bacteria to grow longer," said Dillon Randall, one of the researchers involved in the project.
"The longer the bacterial growth lasts, the stronger the product, the process can be controlled," he said in remarks carried by the British newspaper Mirror.
