The possibility of using building materials to store carbon dioxide is seen as an innovative way to combat global warming.

Researchers from the University of California, Davis and Stanford University have found that these materials, whose production exceeds 30 billion tons per year, have significant potential for carbon sequestration. The greatest effect can be achieved by using concrete with carbonized aggregates. As stated in the study:

"Carbonation of just 10% of concrete aggregates can sequester up to a gigatonne of CO2 annually."

Among promising technologies, the addition of biochar to concrete, the use of bioplastics and asphalt binders based on biomass, and the introduction of biomass fibers into bricks are also highlighted. Some of these methods are already ready for industrial use, while others are still undergoing laboratory testing. As Sebby Miller, an associate professor at the University of California at Davis, noted, even "a small amount of carbon storage in concrete can make a big difference."

The key advantage of this approach is its environmental safety and simplicity compared to conventional methods, such as injecting CO2 into underground reservoirs or ocean depths, which can pose additional environmental risks. The use of building materials as a means of carbon storage contributes to the development of a closed-loop economy, as it involves the use of low-cost biomass waste as a raw material.

Thus, the proposed technologies can not only reduce the concentration of CO2 in the atmosphere, but also stimulate innovations in the field of construction and environmental development. According to the researchers, the further implementation of these solutions can make a significant contribution to the fight against climate change.
