Jonna Ljunge

Jonna Ljunge is a PhD Candidate in the Industrial Ecology group at the Norwegian University of Science and Technology (NTNU), affiliated with the Department of Energy and Process Engineering. She holds a B.Sc. in Civil Engineering (Chalmers University of Technology, 2020) and an M.Sc. in Industrial Ecology (Chalmers University of Technology, 2022). Her research focuses on sustainable infrastructure, particularly the life cycle pathways of construction aggregates in Norway, employing Material Flow Analysis (MFA) to address resource efficiency challenges. As part of the LIFELINE-2050 project under NTNU's Green2050 initiative, she collaborates on optimizing resource use in the built environment. Her work bridges civil engineering and industrial ecology, emphasizing circular economy principles and policy development.

Education:

• Bachelor of Science in Civil Engineering, Chalmers University of Technology (2020)
• Master of Science in Industrial Ecology, Chalmers University of Technology (2022)

Research Interests: Sustainable construction materials, resource efficiency in infrastructure, material flow analysis, policy frameworks for circular economies, and environmental impacts of construction aggregates. Her recent contributions include co-authoring articles on physical economy monitoring and sand flow dynamics.

Outreach & Awards: Awarded for her two-minute video submission to the Buildings & Cities PhD Video Challenge, which highlighted the societal relevance of her research on construction aggregates. Active in academic conferences, presenting at the Industrial Ecology Gordon Research Conference (2024) and the ISIE 2023 conference.

Teaching & Supervision: Supervised an M.Sc. thesis on concrete use in Trondheim’s residential buildings. Engaged in academic outreach through collaborations with industry and policy stakeholders.

Labs & Teams: Core member of LIFELINE-2050, a multidisciplinary team within NTNU’s Faculty of Engineering, focusing on synergistic resource optimization in the built environment under the Green2050 initiative.
