Tallinn University of Technology

On June 10, 2026, the defence of Bachelor’s theses for the Environmental, Energy and Chemical Technology (EACB) programme took place at the Department of Energy Technology, where students presented their research results and practical solutions to contemporary environmental and energy challenges. The evaluation committee gave positive feedback, emphasising both the relevance of the topics and their practical value.

The theses focused on resource valorisation, reduction of environmental impacts, and improving the efficiency of energy systems. Hanna-Liisa Aava studied Selective Extraction of Ionic Compounds for Further Valorization Using the Example of Jordanian Oil Shale Ashes, Arthur Bergvald analysed Assessment of Losses in District Energy Network in an Urban Environment, and Nora Eensalu conducted a Life-Cycle Analysis of Onshore Wind Turbines. Andreas Jakobson examined Heat Transfer Analysis in a Circulating Fluidized Bed Boiler, while Elle Nora Kalind focused on Rare Earth Element Leaching from Industrial Ashes.

In the field of chemical technology and materials science, Elisabet Karro explored the Effect of Water and Sodium Cations on the Properties of Protic Ionic Liquids, and Elys-Anette Soidla investigated the Confinement of Ionic Liquids Within Porous Carbon Materials. Diandra Tubli analysed Transport Properties of Protic Ionic Liquids and will graduate cum laude. Environmental safety topics were addressed by Karmen Kern in Detection and Analysis of Persistent Organic Pollutants in Waste Electrical and Electronic Equipment and by Dmitri Pjatajev in Persistent Organic Pollutants in End-of-Life Vehicles.

Applied aspects of energy and environmental technologies were studied by Aleksandr Kütt, who investigated the Preservation of the Metallic Structure of District Heating Chambers during the Operation, and Pavel Morozyuk, who focused on the Application of Absorption in Energy Technology. Kirke Rannas analysed the Importance of Emission Mapping on the Example of Utilitas Eesti AS Combustion Plants, while Artur Voilenko examined the Analysis of High-Resolution Meteorological Data from Taltech's SOLYS 2 Weather Station.

Research related to biomass and materials included Tuuli Randmäe’s work on the Application Potential of Biomass and Biochar Activated with Potassium Compounds as Hydrogen Adsorbents, Kadri-Liis Salupõld’s study on the Effect of Biomass Composition on the Structural Properties of Biochar Obtained by Carbonisation, and Karolina Toding’s analysis of Industrial Ashes as Cement Additives and Their Effect on the Properties of Cement-Based Materials. Kristjan Uustalu investigated the Effect of Acid Dosage on the Separation of Rare Earth Elements, Iron, and Fluorine from Estonian Phosphate Rock Leach Solutions.

The graduation ceremony will take place on June 25 at 11:00 in the main building auditorium of Tallinn University of Technology.
