Researchers at a South African university have developed a way to make building materials using something we literally flush down the toilet every day.

Urine is the key ingredient in the construction of eco-friendly building materials, human urine that is.

The bio-bricks may be the sustainable alternative to the clay and concrete bricks that currently dominate the building landscape.

The technique used in the prototypes involved “growing” the bricks from urine, similarly to how seashells are naturally formed.The bricks take six or eight days to form.

The invention comes from 2 students and a lecturer at the University of Cape Town.
