3D printing 'greener' buildings using local soil: The construction industry is currently facing two major challenges: the demand for sustainable infrastructure and the need to repair deteriorating buildings, bridges and roads. Concrete has a large carbon footprint, resulting in high waste and energy expenditure. Today, scientists report progress toward a sustainable building material made from local soil, using a 3D printer. The researchers will present their results at the American Chemical Society Fall 2020 Virtual Meeting & Expo.
