The Ingenuity of Scientists and Entrepreneurs Can Find New Uses for the Previously Useless or Underutilitized

(p. D2) It may be unpleasant to contemplate the ultimate fate of all the material from your own body that you flush down the pipes. But it’s time we talk about biosolids — the disinfected leftovers from the water treatment process.

This sandy material contains nutrient-rich organic content that’s good for agriculture. But it also makes nice bricks, according to Abbas Mohajerani, a civil engineer at Royal Melbourne Institute of Technology University in Australia. He’s talking about the kind we use for building.

“Biosolids bricks look the same, smell the same and have similar physical and mechanical properties as normal fired clay bricks,” he said.
