Scientists have found a way to transform leftover human feces into bricks. And they say they are the construction materials of the future.
Sewer sludge is currently thoroughly treated and dried out, but the remainder of the 'biosolid' remains are unused and sent to landfill This method combines clay with feces to create a unique form of building material. Scientists created bricks with 25 per cent feces and the rest traditional clay and found the block still managed to pass stringent strength tests.
They were also more porous and better insulators. The bricks are able to stand up to the strictest building regulations and have added thermal benefits but are also are more energy efficient to make.
