Title
PhD Student in Biogas Utilisation from Deep Litter
Research area and project description
The PhD project is part of the research project DEEP-GAS, which investigates the potential for biogas production using deep litter from barns. Removal frequent may affect the biogas potential of deep litter by changing degradation losses in the barn, but scientific knowledge on how litter age and inclusion level affect biogas production, process stability, and digestate emissions is limited.
The PhD project will focus on laboratory and pilot-scale biogas experiments to quantify the biochemical methane potential (BMP) of slurry containing deep litter of different ages and at varying inclusion levels. Based on laboratory screening, selected treatments will be tested in pilot-scale reactors to reflect realistic operating conditions at Danish biogas plants. The project will also quantify emissions from storage of digestate with different deep litter contents, providing essential data on climate effects.
The PhD student will be responsible for planning and conducting biogas experiments, analysing gas production and degradation kinetics, and contributing to carbon and nitrogen balance modelling for biogas systems. The results will support the development of practical guidelines for integrating deep litter into biogas plants and provide knowledge relevant for climate mitigation strategies in agriculture. The project is conducted in close collaboration with farmers, SEGES, and the Danish biogas sector to ensure strong practical relevance.

A master’s degree (120 ECTS) or at least one completed year of a master’s programme in biotechnology, environmental engineering, chemical engineering, agricultural science, bioengineering, or a closely related field.
Documented interest in anaerobic digestion, biogas production, bioenergy systems, or organic waste management.
Ability to work independently and take responsibility for experimental planning, while also contributing effectively within a research team.
Experience with laboratory or pilot-scale biogas experiments, including BMP testing or reactor operation, is an advantage.
Experience with physical and chemical analysis of biomass, manure, or digestate is an advantage.
Strong quantitative and analytical skills, including experience with data analysis tools such as R, Python, Matlab, or similar.
Ability to analyse and interpret experimental data and contribute to process modelling and mass balance assessments.
Good written and spoken English. Danish language skills are an advantage but not required.
