Want to cut carbon emissions? Try growing cement bricks with bacteria

To make bricks, bioMASON engineers start by pouring a pitcher of primed bacteria into a mixer full of foundation material, such as sand or pebbles. Paddles churn the concoction, so the bacteria slip evenly in-between the particles of the rocky material.Next, the tank holding the brew tips upward, and the goop slides into machine called “the hopper.” The wet biocement funnels into the hopper’s brick molds, and a hydraulic plate covers them. Flip a switch, and the plate presses into the material while vibrating furiously.  http://www.pbs.org/newshour/updates/carbon-emissions-growing-cement-bricks-bacteria-biomason/
