Montreal-based CarbiCrete has issued its first carbon removal tons generated through CO2-negative concrete. The milestone update was shared by the company’s exclusive carbon markets partner 3Degrees Group.
These carbon removals represent one of the earliest issuances under Verra’s VM0043 methodology for CO2 Utilization in Concrete Production, version 1.1.
CarbiCrete’s patented technology uses industrial by-products and captured carbon dioxide to produce cement-free, carbon-negative concrete, creating a promising decarbonization solution for the building industry.
Conventional concrete is made with cement – a component whose production on a global level accounts for nearly 10% of the planet’s CO2 emissions.
To help address this problem, CarbiCrete has replaced the carbon-heavy cement in the mix with steel slag – an industrial waste available for much lower costs.
The company’s climate-forward technology can be implemented in any concrete products plant. When installed at a facility, the system uses carbonation activation, injecting CO2 into the wet concrete to fortify the mix.
Since this process enables captured carbon dioxide to be permanently sequestered in the concrete, the products created with CarbiCrete’s technology are CO2-negative.
In a recent publication, 3Degrees Group labeled the carbon removal issuance as a groundbreaking moment, sharing, “Moving from concept to verified, high-integrity carbon removal is a massive step forward for decarbonizing the built environment—one of the toughest emissions challenges we face today.”
For CarbiCrete, this achievement comes a few months after the company successfully secured CA1million(~US7 million) in support from Innovation, Science and Economic Development Canada (ISED) and the National Research Council of Canada (NRC) to advance its low-CO2 concrete technology.
