Field-deployable leaching columns at Trent University.
Now that spring is here, we are taking advantage of the nice weather and transitioning Duncan’s enhanced weathering columns to an experimental space on Trent’s campus. After 20 weeks of artificial weathering in the laboratory, we’re letting natural processes take over while monitoring the columns throughout the summer and into the fall. Real-world conditions will help us better understand these feedstocks’ weathering rates and their ability to sequester CO2 through enhanced rock weathering. During this second phase of the experiment, we will continue to track carbon as a solid, aqueous, and gaseous phases. These columns are designed for deployment at a mine site to monitor drainage chemistry and are being improved upon in our second prototype expected to be deployed in the coming weeks.
