Carbon-Negative Concrete
Even though builders use concrete in everything, from roads to buildings, it doesn’t mean it’s good for the environment. It releases tons of carbon dioxide into the air that’s harmful and accounts for eight percent of carbon emissions. However, researchers are staying on top of this with energy breakthroughs called carbon-negative concrete. The name says it all. It’s the eco-friendly sibling of concrete, and it soaks by swapping out some of the concrete’s materials for greener alternatives.
According to Spectrum, “They made the carbon-negative concrete by replacing a third of the cement in it with biochar, a kind of charcoal made from agricultural and forestry waste.” This will cut down all those harmful emissions during production. Not only that, but the material will suck up carbon dioxide from the air. Moreover, some other companies are tackling the concrete issue by adding biological materials like algae, blood enzymes, and bacteria to help lessen emissions and pull harmful gases from the air (Spectrum).
