The biogeotechnology that has attracted the most attention in recent years is mineral precipitation. In particular, engineers have focused on precipitation of calcium carbonate (calcite) to turn cohesionless sand into a sandstone-like material. Applications of carbonate precipitation include fugitive dust control, slope stabilization, tunneling in running and flowing sands, enhancement of foundation bearing capacity, and mitigation of the potential for earthquake-induced liquefaction. There are also a number of other applications of mineral precipitation being explored biogeotechnologists, including craton of subsurface barriers, sequestration of radioactive contaminants in groundwater, and removal and recovery of other groundwater contaminants.
Dr. Edward Kavazanjian, Jr. is a Regents Professor and the Ira A. Fulton Professor of Geotechnical Engineering at Arizona State University. He joined the faculty at Arizona State University in August 2004 after 20 years as a practicing geotechnical engineer. Dr. Kavazanjian has Bachelor and Master of Science degrees in Civil Engineering from M.I.T. and a Ph.D. in Geotechnical Engineering from the University of California at Berkeley. In 2013, he was elected to the National Academy of Engineering for his work on design and construction of landfills and geotechnical earthquake engineering. He is recipient of the 2009 Ralph B. Peck Award, 2010 Thomas A. Middlebrooks Award, and the 2011 Terzaghi Award from the American Society of Civil Engineers (ASCE). In August 2015, he became Director of the Center for Bio-mediated and Bio-inspired Geotechnics (CBBG), a National Science Foundation-funded Engineering Research Center dedicated to the emerging sub-discipline of biogeotechnical engineering.
