New bio-based fertilisers from organic waste upcycling.

The EU is heavily import dependent for more than 90% of the nonrenewable phosphorus and synthetic nitrogen fertilisers consumed. This has large economic cost (more than €15 billion/y) and negative environmental impacts from fertiliser production and use. European farmers and fertiliser industry therefore urgently need techniques for increasing substitution of synthetic with waste-derived nutrients formulated into high-quality, bio-based fertilisers to fulfill the EU action plan on circular economy. However, this requires research into new processing, application and assessment and more innovative and entrepreneurial scientists capable of meeting these future needs – FertiCycle aims to to fill this gap.

PhD Fellows

FertiCycle will train 15 PhD fellows (Early Stage Researchers) who are clustered in five work packages according to the focus of their research, as illustrated in the figure below.

Contact:  schrysanthopoulos@isa.ulisboa.pt

Country of origin:  Greece

Project:  pH modification of animal manures as tool for reducing emissions and improving fertiliser value.

Place of Enrollment:  University of Lisboa, Portugal

Principle Supervisor:  Prof. David Fangueiro

I am a Greek PhD student, currently living in Lisbon, Portugal. I hold an MSc degree in horticulture which reflects my passion for plants. In the Netherlands, I obtained an MSc degree in Biobased Sciences from Wageningen University. My internship placement as well as several projects I was involved in the Dutch environment allow me to further improve my skills in the Bio-based fertilizer sector.

The research areas I specialize are: Circular economy, waste upcycling and sustainable manure management.
















Contact:  y.zireeni@bangor.ac.uk

Country of origin:  Israel

Project:  The role of sulphur in nutrient supply from processed slurry and digestates

Place of Enrollment:  Bangor University, Wales, UK

Principle Supervisor:  Prof. David Chadwick

I am an Israeli-Arab/Palestinian early stage researcher (ESR).

Formerly I worked as an agronomist for the Israeli ministry of agriculture, as lecturer and translator for the economic cooperation foundation (ECF), and as a tutor at agricultural high school.

I graduated from the Robert H. Smith Faculty of Agriculture, Food and Environment, the Hebrew University of Jerusalem
BSc. and MSc. in soil and water sciences

In my spare time I try to learn or develop new hobbies, exercise or visit beauty shops. I love travelling, food, science and art.














Contact:  Samaya.ElHajjHassan@UGent.be

Country of origin:  Lebanese Republic

Project:  Economic Evaluation of the inclusion of bio-based mineral nutrients in the fertilisation strategies across the EU.

Place of Enrollment:  Ghent University, Belgium

Principle Supervisor:  Prof. Jeroen Buysse

I’m a Lebanese living in Ghent, Belgium. I had my BE in agricultural sciences and master’s degree in agricultural economics from the LU in Beirut. I also received a master’s degree in environmental and territorial development from a joint Erasmus + program between France and Lebanon. Following my graduation, I was fully engaged in the sectors of water, sanitation, hygiene, food security and livelihood in several humanitarian iNGOs.

My research interests predominantly lie in fields of bio-economy and climate change mitigation.
