Using Dirt to Clean Up Construction

Concrete ranks as the most popular construction material in the world. But its key ingredient, cement, is responsible for 8% of global carbon dioxide emissions each year. Scientists want to replace concrete with a more environmentally friendly material, and one candidate is soil. In one of the most recent iterations of these efforts, the Banerjee Research Laboratory at Texas A&M University has created a tool kit for using local soil to make construction materials. - EOS
