Building Material Innovation that Could Revolutionise Construction

Academics at the University of Cape Town in South Africa may have found an eco-friendly alternative to the standard construction bricks we use today.

Instead of the regular clay and concrete building blocks we use today, one day bricks could be “grown” in much the same way as seashells, using human urine.

The world first bio-bricks take 6 to 8 days to form using a technique similar to the natural formation of seashells.

A feasibility study was launched last year using synthetic urea and academics then escalated the study to use human urine.

In his lab, the UCT professor and 2 students created their first bio-brick using the natural process of microbial carbonate precipitation. This involves mixing urine, sand and bacteria to make a brick.

It takes 30 litres of urine to make a single brick.
