The University of Kassel is a modern and growing University with round about 23.000 students. The university’s wide range of expertise covers subjects in the natural, applied, cultural and social sciences.

Faculty of Organic Agricultural Sciences, Institut of Grassland Science and Renewable Plant Resources (Prof. Dr. Wachendorf), the following position is to be filled as soon as possible:

Research Assistant (m/f/d), EG 13 TV-H, temporary, part-time (currently 26 hours per week)




as soon as possible

Kennziffer: 36582

Part-time with 65 percent of the regular working hours of a full-time employee. The position is initially limited until 28.02.2027 as part of the project of the Junior Research Group "Bio4Act - Biogenic activated carbons and platform chemicals from residual biomasses for the implementation of a sustainable circular bioeconomy" in accordance with § 2 para. 2 WissZeitVG. The possibility of doctoral studies is given. After successful completion of the doctorate, continued employment until the end of the project on 31.07.2028 is aspired.

The junior research group, funded by the German Ministry of Education and Research (BMBF) aims to develop and investigate sustainable technology and utilization concepts for residual biomasses by converting them into high-quality activated carbon, platform chemicals and renewable energy carriers. This is intended to replace fossil raw materials with biogenic equivalents and at the same time contribute to the preservation of ecosystems. The junior research group comprises three PhD positions, two PostDoc positions and one technician position at the University of Kassel. Within the framework of the junior research group, the position holder will work on the following topics:

  • Production of biogenic activated carbons by pyrolysis from residual biomass for the removal of organic micropollutants from wastewater
  • Characterization and evaluation of biogenic activated carbons for the substitution of fossil equivalents
  • Investigating the potential of pyrolysis gases for the production of green hydrogen


  • Independent scientific research activities in the field of activated carbon production from residual biomasses using the pyrolysis and activation reactor of the department on a laboratory scale
  • Systematic research of adapted process settings for the optimized production of biogenic activated carbons from residual biomasses for the removal of organic micropollutants from wastewater
  • Planning, execution and evaluation of independent experiments for the physico-chemical characterization and evaluation of biogenic activated carbons, taking into account the initial biomasses and process settings
  • Determination of material and mass flows as well as energy balances of the process
  • Documentation, evaluation and assessment of the experimental results
  • Preparation and presentation of new knowledge and the results of research work in international peer-reviewed journals and participation in scientific events
  • Contribution to project reports


  • University degree (Master) with at least good results environmental engineering, chemical engineering, process engineering, environmental sciences or a related field. The required degree must be obtained by the recruitment date at the latest
  • Knowledge and experience or a willingness to become proficient with the activated carbon and biochar research field
  • Knowledge and experience with methods, particularly for the characterization and evaluation of biogenic activated carbon
  • A high level of interest in research and development of innovative technology concepts for the sustainable use of biogenic resources
  • Capability to connect one's individual studies to the larger context of climate and sustainability
  • Thorough and independent working style
  • A high degree of organizational and teamwork skills
  • High interdisciplinary willingness to learn and cooperate
  • Good oral and written communication skills in German and English or willingness to learn the language


  • In-depth basic knowledge of thermochemical conversion processes (pyrolysis)
  • Basic knowledge of urban water management and new developments in advanced wastewater treatment
  • Previous experience in the field of production and environmental application of activated carbon and biochar
  • Scientific expertise, preferably demonstrated by a degree in a field of activity relevant to the junior research group
  • Knowledge of statistical data analysis, ideally also experience in using script-based software (e.g., R or Python)
  • Class B driver's license
  • Experience in knowledge transfer and inter- or transdisciplinary collaboration
  • Experience in the field of material flow analyses
  • In-depth experience in laboratory work
