Carbon negative concrete. And without cement.

We already published three interesting articles about newer - climate friendlier - processes of producing cement:

• Heidelberg Cement produces cement using hydrogen technology. About a test using a 100 percent blend of climate-neutral fuels, including hydrogen, to manufacture cement on a commercial scale. If fully implemented for the entire kiln system, nearly 180,000 tonnes of carbon dioxide could be avoided each year, compared to using fossil fuels like coal.

• Expert explains how to transform industrial carbon into building materials. About Mineral Carbonation International's plan to block 1 billion tons of CO2 in building materials, industrially applying - a matter of hours - the natural process that occurs in millions of years of Earth's CO2 storage, which is called mineral carbonation or weathering.

• European VC $158 Million Fund To Find Tech Solutions To Real Estate’s Sustainability. About CarbonCure Technologies, a Canadian company whose technology lowers the cement content of concrete while storing carbon dioxide in the concrete itself, reducing the material’s carbon footprint.

Adding to this series, we have now the case of precast concrete from CarbiCrete, a Montreal-based carbon removal technology company. The company developed a patented technology that enables the production of cement-free, carbon-negative concrete using industrial by-products and captured CO2. Sounds very interesting, no ?
