Lisbeth M. Ottosen

Lisbeth M. Ottosen is a Professor and Head of the Section for Materials and Durability at the Department of Environmental and Resource Engineering, Technical University of Denmark (DTU). She leads the department’s focus area on 'Circularity in Civil Engineering' and was the lead professor in DTU’s sector development project 'Circular Construction 2019–2020'. She is also a member of the Academic Council at DTU since 2018.

Her research centers on the recovery of resources from secondary waste streams and the sustainable use of these in construction materials. Key areas include urban mining of phosphorus and heavy metals from sewage sludge ash and incineration residues, and the application of electrokinetic processes for resource extraction. She also investigates the use of secondary materials such as fly ash, mine tailings, and recycled concrete in cement, bricks, and fiber-reinforced concrete.

Her recent publications reflect a strong trend in sustainable construction, waste valorization, and electrochemical remediation. Work spans from laboratory experiments to pilot-scale applications, emphasizing circular economy principles and contributions to UN Sustainable Development Goals, especially in responsible consumption and climate action.

Scientific Awards:

• Annual DTU Award for Developing Teaching and Learning (2017)
• BIOFOS Ressourcepros 2023

She actively supervises multiple PhD students and leads significant research projects such as 'Recovery of Resources from Ashes' and 'GREENCO: Education for Green Transformation of the Construction Sector'. Her work integrates research, education, and industrial collaboration to advance sustainable practices in civil engineering.

She is involved in several laboratories and research teams focused on materials durability, electrochemical processing, and circular construction. These teams collaborate across disciplines and with external partners to develop scalable solutions for waste-to-resource technologies.
