Stone Made of Urine, Sand and Bacteria

Someday, our buildings may be constructed from stones made of urine, sand and bacteria.

A project developed by Peter Trimble, a graduate of the Edinburgh College of Art, has investigated the possibility of producing stone materials through “microbial manufacturing.”

Through his project, Trimble was able to produce biostone, a small stone shaped like a stool that is structurally comparable to concrete, according to the designer’s website.

"In a world increasingly concerned with questions of energy production and raw material shortages, this project explores innovative and sustainable means of material production," according to Trimble.

He manufactured the stone using Dupe, a portable machine that uses very little energy and produces no greenhouse gases.

The casting procedure presents a method of cementing natural granular materials using minerals as a binding agent, according to the website. This video shows the production process.

The designer admits the project doesn’t provide “definitive answers,” but at the very least it might provoke new ways of thinking regarding building material production.

Trimble’s not the only one researching unusual ways to make sustainable building materials. Remember blood bricks?
