Seratech carbon-neutral concrete wins Obel Award 2022

British company Seratech has won the architecture-focused Obel Award with its prototype carbon-neutral concrete, which it says is low-cost and easy to scale.
Founded by PhD students Sam Draper and Barney Shanks to commercialise their research at the Imperial College London, Seratech replaces part of the cement content of concrete with a type of silica created using carbon dioxide captured directly from factory flues.
Only a maximum of 40 per cent of the cement content of concrete can be replaced
