Material scientists Sam Draper and Barney Shanks landed the €100,000 2022 Obel Award with their ‘simple way’ to capture carbon from industrial production processes and create an end product that can eliminate the CO₂ footprint of concrete.
The prototype technology, dubbed Seratech, takes industrial CO₂ emissions directly from flues and produces a carbon-negative cement replacement material (silica). According to the scientists, when this is used in combination with Portland cement, the carbon capture associated with producing the silica means the concrete products can be zero carbon.
