A normal clay brick is dug from a quarry and fired in a gas kiln at around 1,000 °C. The K-BRIQ is pressed from crushed old bricks, rubble, mortar and plasterboard, and cured without any firing.
India's metal foundries throw away fine, dusty sand that is too small to reuse. Its towns are full of plastic too dirty or mixed to recycle. A Gujarat foundry machinery firm melts one into the other and presses the result into paver blocks.
