Bruk Dejenie, a graduate from Aalto University, was recently awarded the best geotechnical thesis of the year by the board of the Finnish Geotechnical Society. The winner was announced on 3 November at the Geotechnical Day, and Dejenie received an award from FinMeas Oy for his work on the "Carbon Dioxide Sequestration Capacity of Stabilized Malmi Clay".
The focus of Dejenie's research was on the ability to absorb carbon dioxide in different types of stabilising agents in clay under laboratory conditions . Various low-carbon emission, recycled material-based stabilising agents, in addition to Malmi clay, were also used in the study. This groundbreaking research is a preliminary study for future research that will test carbonation using multiple stabilising agents and quantities. The results of this study will also be used in extensive laboratory and field tests in the future.
The award-winning thesis combines a modern and current perspective that has been studied through literature and several laboratory tests. This work is part of an effort to minimise energy consumption and carbon dioxide emissions in soil improvement projects, allowing the geotechnical design sector to take a leading position in implementing more environmentally sustainable projects.
The FinMeas Oy thesis prize for the best final thesis in geotechnical engineering was awarded this year for the ninth time. All universities teaching geotechnical engineering, including Aalto University, Tampere University, and the University of Oulu, participated in the competition. Bruk Dejenie was chosen as the winner, while Antti Rahko from Tampere University and Paula Liisanantti from the University of Oulu also made it to the top three.
