Job Type: FullTime
Deadline: 16 Apr 2020


Ghent University (Belgium) is internationally one of the leading institutes in resource recovery and renewable resources. It is home to the BioRefine Cluster Europe ( ), a network of international research and development projects with the dedicated focus of guiding innovation towards applied market implementation.

As part of the Ferticycle program, a Marie Skłodowska Curie -European Training Network, we are recruiting a junior expert for a PhD degree at Ghent University (Belgium). The goals of the European Training Network ‘New bio-based fertilisers from organic waste upcycling (FertiCycle)’ will be achieved by a unique combination of “hands-on” research training, non-academic placements, and workshops on research-related and transferable skills.

Research content

The candidate will focus on integrating bio-based fertiliser production into bio-refinery business concepts. Semi-continuous pilot assessment trials will be performed to achieve optimal biogas yield combined with optimal end-product fertiliser value and quality, taking into account trace metal quality criteria and the optimal NPK nutrient ratio based on crop requirements. For that, the necessary mechanistic algorithms of individual unit process steps will be developed to simulate and predict an ideal feedstock composition to obtain an optimal mineral nutrient composition of end-products (NPK, Ca, Mg, trace elements).

The chosen candidate will pay special attention to the behaviour and fate of undesired components (contaminants) in the digestate. Particular technical challenge will be to minimise undesired trace elements (heavy metals) by adjusting feedstock and process parameters (e.g. precipitation/separation) using process engineering and producing criteria to control effects of variable mineral availability in different soil types. Potential contaminant build-up and behaviour (transformation, speciation) through anaerobic digestion process will be studied, as well as nutrient transformation modelling and bio-assay ecotox-assessment will be applied to predict product characteristics.

Job tasks

Your key tasks as an Early Stage Researcher (ESR) member of the Ferticycle Network and as a PhD student are to:

  • Perform independent scientific research, as well as collaborate with other members of the international FertiCycle research network.
  • Participate in international secondments (internship as visiting researcher) to other organisations in the FertiCycle network.
  • Attend the FertiCycle training programme as well as other PhD courses.
  • Deliver written reports of your research on a regular basis.
  • Write and publish scientific articles related to your research project and write your PhD thesis.
  • Support the valorisation of research results into tangible deliverables.

We offer

  • Full-time employment for a period of 3 years – with the possibility of a 1-year extension
  • The position is available from 1 June 2020, latest start on 1 September
  • Being embedded in a team of young, dynamic experts on nitrogen and phosphorus recovery from academia and industry
  • Close supervision and guidance in the conducting of the planned research
  • Stimulation to self-improvement by encouraging participation in outreach activities aimed to promote your own scientific research such as summer schools, workshops, and conferences
