Department of People and Technology, Roskilde University, invites applications for a position as postdoc of integration-synergies between anaerobic digestion and biomass pyrolysis from 1st of January 2026 or as soon as possible thereafter. The position as postdoc is limited to a period of 2 years.

The Department of People and Technology at RUC is involved with development of sustainable solutions, applying experimental approaches and supporting people’s active commitment. The Department is covering human, society, health and IT scientific fields as well as planning, intervention and design inclined fields. The postdoc is anchored in the research group Sustainability Transitions and Environmental Planning. The research group addresses the urgent need for sustainability transitions in response to today’s complex and interconnected ecological, technological, and socio-political crises. The group generates inter- and transdisciplinary knowledge to support an environmentally sustainable development and reduce resource consumption across key societal sectors.

The biogas sector in Denmark is large and deeply integrated in both the waste-, energy- and agricultural sectors. Since 2021, the development of a pyrolysis sector has also been picking up speed and there is a growing focus on the integration of pyrolysis and biochar use into modern biogas plants. Currently, there are two industrial biogas plants with pyrolysis plants established or under establishment, and more are expected to come. Many potential synergies between the two technological platforms are under investigation and this postdoc will contribute to develop, validate and analyze potentials for some of these integration-synergies between anaerobic digestion and biomass pyrolysis.

Responsibilities and tasks
The position has broad orientation of this topic spanning activities, perspectives and methods across the spectra of social science, natural science and technical science. The work includes lab scale experimental development and proof-of-concept analysis, mechanistic studies, pilot scale assessment on-site at full scale plants in operation, feasibility analysis and climate impact assessment studies.

The research in the project is funded by Fonden For Retfærdig Omstilling and the relevant tasks are conducted as part of the Pyto-CCUS project managed by Energy Cluster Denmark. In addition to research, the position includes roughly 25% teaching and project supervision primarily in Danish.

The ideal candidate is expected to
  • Design and develop new experimental lab-setups as needed to investigate integration-synergies between anaerobic digestion and biomass pyrolysis
  • Investigate/ validate/ optimize effects of potential integration-synergies in the lab and field, hereunder H2S adsorption on biochar and the effect of biochar on anaerobic digestion processes
  • Apply knowledge from the lab and field to feasibility studies and climate impact assessment studies, including relevant aspects of economy, regulation, planning and quantitative sustainability assessment methodology
  • Document and disseminate findings in project meetings, conferences, reports and scientific papers
  • Contribute to course teaching and project supervision at the RUC based educations Humtek (Danish), Sustainable Transition (Danish) and Natural Science (Danish and English)


Qualifications
Applicants must hold a PhD or equivalent within technical- and natural science investigations of anaerobic digestion and biomass pyrolysis and have proof of substantial teaching experience. Qualifications within the following scientific areas are required:
  • Technical science investigations of anaerobic digestion- and pyrolysis processes including development of new experimental setups and lab scale processes simulating industrial scale plants, determination of energy- and mass balances and coding of systems for data acquisition and -logging
  • Natural science investigations of biochemical methane potentials and gas adsorption on biochar and active carbon substrates, as well as experience with determination of proximate analysis, ultimate analysis, elemental analysis, higher heating value etc.
  • Social science investigations of technological impact- and deployment potentials taking into account biomass availability, economic costs and benefits, regulatory barriers etc.
  • Experience in collaborating with experts and practitioners in industry and project consortia and conducting research under externally funded research projects
  • Substantial teaching- and project supervision experience within topics related to sustainable transition and environmental planning across both the technical-, natural, and social sciences.


The ideal candidate shall be enterprising and possess good communication skills, be visible and involved in the department’s daily activities, in addition to being willing to engage in disciplinary and interdisciplinary collaboration across the department.

Assessment
In the assessment of the candidates consideration will be given to;
  • scientific production and research prospective,
  • the ability to promote and utilize research results,
  • experience in teaching and education
  • ability to contribute to development of the department’s internal and external cooperation,
