‘Breakthrough’ cementless concrete passes carbon-negative tests


A new type of concrete that forgoes the necessity for cement has been confirmed as carbon-negative following lab tests undertaken at the University of Oxford.

Developed by CarbonMeta Technologies, Inc (CarbonMeta), EarthCrete Cementless Concrete was found to capture up to 10% carbon dioxide (CO2) by weight during production.

Accounting for around 8% of global CO2 emissions, the notoriously hard-to-abate concrete manufacturing industry could see its carbon footprint significantly reduced with innovations in carbon-negative concrete.

According to CarbonMeta, a single project using 1,200 metric tonnes of EarthCrete concrete mixed with water can absorb up to 132 atmospheric metric tonnes of CO2, equivalent to 66 diesel vehicles each being driven 12,000km per year.
