Hello, folks! We recently had contact with Northeastern University about sand. I know it sounds ... dry. But sand shortages are a serious issue globally and are leading to criminal activity everywhere and even "sand mafias" in poorer nations without resources to enforce mining laws.
The ask from Northeastern is that BuildingGreen amplify its efforts to both learn and educate about sand alternatives in concrete. They are doing online surveys and interviews with people from the U.S. and Canada. (Apparently they're having a hard time finding Canadian participants, so keep that in mind, those of you in the north!)
Easiest way to help is to fill out a 10-minute survey. If you'd be interested in a more in-depth interview, you can contact Paul Wallace, paulwallace@pwallace.ca.
Thanks for considering, everyone!
