Green Alchemy: Sewage into Bricks!

Here's a creative way to cut carbon emissions and reuse waste: turn sewage into bricks for construction purposes. That's right, incinerated sewage sludge is being combined with a vegatable oil based binder to be used in masonry. Normally traditional bricks are made out of concrete, made from cement, which when produced releases carbon dioxide emissions, 5-10% globally. The bricks made from sewage are completely CO2 free, meaning that they will greatly reduce emissions if they are widely used, replacing traditional bricks.

"The blocks and bricks do not smell and have been tested for and passed industry standards for heat, freezing, and strength."
