Soil Article Compares Gray and Green Infrastructure

SAGE member Pam Judge wrote to share an article find she thinks SAGE should read.  The paper is by Chang et al 2016 "Introduction of Microbial Biopolymers in Soil Treatment for Future Environmentally-Friendly and Sustainable Geotechnical Engineering.  Pam wrote, "I think it does a nice job of comparing traditional "gray" technology of soil improvement (portland cement) with the more "green" alternative (biopolymers).  It compares the technologies in terms of carbon footprint, cost, effectiveness, constructability, etc.  I found it an interesting and timely article, and thought it might be a nice addition to the SAGE library."
