Two companies have created concrete that captures CO2 from the atmosphere

The winners of the XPRIZE competition came up with a technology to create concrete that captures carbon dioxide. He

holds it in to reduce itconcentration of this substance in the atmosphere. It's worth noting that the production of cement, the main ingredient in concrete, accounts for about 7% of global greenhouse gas emissions. This was stated by Marcius Extavur, vice president of the XPRIZE organization, the initiator of the climate and energy competition.

The winner of the $20 million competition was announced inat the beginning of the week, and on Thursday it is planned to launch another competition of the organization. This time the initiative will be supported by businessman Elon Musk. The entrepreneur promised $100 million to those scientists whose projects will help capture CO2 from the atmosphere and store it for a long time.

The two main winners are CarbonBuilt andCarbonCure Technologies. They will split $15 million between themselves and use it to improve and scale their technology for producing carbon dioxide-capturing concrete. The remaining $5 million was divided among the 10 other finalists.

CarbonCure Technologies, inventeda technology in which carbon dioxide is added to the water used to flush cement trucks and mixers in a cement plant. The result is a mixture from which a more durable concrete is obtained. Los Angeles-based CarbonBuilt used carbon dioxide to cure concrete. This process has helped to emit fewer greenhouse gases compared to traditional cement production methods.
