Lab tests at the University of Oxford have confirmed the ability of CarbonMeta’s carbon-negative concrete to absorb CO2.
The breakthrough material has been branded as EarthCrete Cementless Concrete and has been confirmed to capture as much as 10% of CO2 by weight production.
Concrete is known for its incredible emissions intensity, with the notoriously hard-to-abate industry accounting for some 8% of global carbon dioxide emissions.
Hence, this innovation has the potential to significantly impact the battle against climate change and help reduce CO2 emissions in the world.

To illustrate the effectiveness of its now tested and certified product, CarbonMeta Technologies provided an example of a project using 1,200 metric tons of its carbon-negative concrete that would absorb 132 tons of carbon dioxide per year, which is roughly the amount emitted by 66 diesel-powered cars running an average of 12,000 miles in that same time.
In a comment on the positive test results, CarbonMeta CEO Lloyd Spencer expressed his hopes that the successful trials of EarthCrete would help the built environment offset its own CO2 emissions.

Great show on carbon negative concrete. Here’s another one you didn’t cover, that I just bumped into. It’s a company called Sublime (that’s a pun in case you didn’t catch it). They use a room temperature process that involves calcium-bearing silicates, not limestone, with electrolyzers not heat as the agent.
