Tavs Jorgensen develops cob bricks for low-carbon construction

Researcher Tavs Jorgensen has created a method of extruding cob into brick shapes, in an effort to make the low-carbon biomaterial more accessible.
Used to create bricks that can be stacked in interlocking patterns, the process involves pushing different samples of cob – a construction material made from earth and straw – through 3D-printed extrusion moulds known as dies.
It was developed as part of a research project at the University of the West of England's Centre for Print Resear
