COMPACT CHAFF

Chaff is a common leftover all over the world – from rice, corn, millet and other crops. Their often high content of silicon dioxide offers the possibility to turn them into fibre reinforced cement by using bacteria that are able to produce biominerals – in this case bio cement, gluing the husks together using the silica from the husks. The resulting material alters depending on the site-specific kind of chaff, but the process is the same. We developed a simple and mobile tool that makes the process available to almost everybody.
