World’s first bio-brick grown from human urine

A University of Cape Town student has invented the world’s first bio-brick grown from human urine.

The bio-brick was developed by UCT master’s student in civil engineering, Suzanne Lambert.

She joined Joanne Joseph on the Afternoon Drive to explain the science behind this.

It is modeled off a process that happens in nature, kind of how coral is formed and how it is formed is a bacteria that makes a chemical process happen and that chemical process produces a calcium carbonate and calcium carbonate is one of the main ingredients in concrete and cement.

So it is just that process accelerated using slightly different bacteria and the bacteria uses the urea in urine to produce calcium carbonate.

There is so many nutrients and things that you can recover from urine.
