With a growing huge dump of biosolids constantly growing around the world. A civil engineer in RMIT’s School of Engineering who is one of the lead researchers in the study.
The bricks are made of 25 percent human feaces and 75 percent traditional resources.

The journal of Buildings expatiated:
“Millions of tonnes of leftover biosolids are increasingly stockpiled every year around the globe. Biosolids are a product of the wastewater sludge treatment process. Stockpiles necessitate the use of large areas of increasingly valuable land. Biosolids have many beneficial uses and are currently utilised in agricultural and land rehabilitation applications. However, it is estimated that 30% of biosolids are unused and stockpiled.”

The bricks were tested and found out to be cheaper than traditional building blocks. They turned out to be better insulators than traditional blocks, as they also use lesser energy to produce.
Consequently, this process cuts down on the amount of clay used to produced the blocks.
“A second and seemingly unrelated environmental issue is the massive excavation of virgin soil for brick production. The annual production of 1500 billion bricks globally requires over 3.13 billion cubic metres of clay soil—equivalent to over 1000 soccer fields dug 440 m deep or to a depth greater than three times the height of the Sydney Harbour Bridge.”
