Project leader
Hannah van Zanten
“A transformation of our food system is required to safeguard our planet for future generations”
More about
Dr. Hannah van Zanten is the project leader of the circular food systems project. She is Associate Professor at the Wageningen University Farming Systems Ecology group. It is her ambition to unravel how circular food systems can contribute to producing healthy foods for a growing population within the carrying capacity of the Earth. Hannah graduated cum laude from Wageningen University in 2009 with a master’s degree in Animal Sciences. Her PhD project focused on the environmental benefits of using human-inedible-sources as livestock feed. Since graduating, again cum laude, for her PhD, she continued to work in this research-area with the Animal Production Systems group, and later with the Farming Systems Ecology group. She recently was awarded the NWO Talent Scheme grant (VENI) in which she aims to assess the role of animals in a circular food system. Her research shows that farm animals reared under a circular paradigm can play a crucial role in feeding humanity, while reducing the environmental impact.

Project assistant
Demi Hordijk
“Working in an interdisciplinary manner towards sustainable, fair and healthy food systems"
More about
Demi is a project assistant of the Circular Food Systems project. She studied the bachelor Biomedical Sciences at Maastricht University (2018) and did the master Nutrition and Health at Wageningen University (2021). During her masters, she specialised in epidemiology, public health and global nutrition. Her thesis focused on nutrient adequacy and food-based dietary guidelines adherence in different districts in Vietnam, and how these were influenced by the food environment. During her internship at Table, her interests broadened towards food systems, climate resilience and sustainability. After her internship, she wanted to continue working on these relevant themes in an interdisciplinary way, which is why she is very excited to be a part of the CiFoS team.

Loekie has started his PhD in 2018 at the Wageningen University and Research, at the Farming Systems Ecology group and Animal Production Systems group. His research focusses on the transition towards regenerative agriculture.
Loekie was born in the Netherlands, where he graduated from the University of Applied Sciences with a BSc-degree in Mechanical Engineering. The focus of his BSc-thesis was the design of circular large-scale productions systems to produce housefly larvae for feed. His MSc-degree was obtained from the Wageningen University and Research in Biosystems Engineering where he continued studying edible insects. His first thesis focused on the assessment of the thermal environment of mealworm kept in a large-scale production system. This study was in collaboration with Proti-Farm a large scale producer of edible insects. A second thesis focused on greenhouse gas emissions produced by growing mealworms assessed by flow-through respirometry. This study was conducted within the inVALUABLE project, in collaboration with the Danish Technological Institute.

Wendy Jenkins
"In order to supply healthy diets to a growing population while preserving some semblance of nature, an interdisciplinary approach will be pivotal"
More about
Wendy started her PhD in 2021 at the Wageningen University and Research Farming Systems Ecology group. Her research aims to investigate how diet can be used to prevent species loss.
Wendy holds an honors bachelor’s degree in Environmental Biology from the University of Guelph, Canada and an MSc in Nutrition and Health from Wageningen University and Research, the Netherlands. Through her studies, Wendy has focused on the intersection of these two fields and bridging some of the gaps between them. This focus was applied in her MSc thesis, where she designed a model to maximize the nutritional output of an area of land, thereby reducing the land use required to feed people. Wendy also has experience working in the sphere of health communication and is the primary author of ‘The Portfolio Diet for Cardiovascular Disease Risk Reduction’ a cookbook and guide for patients and clinicians on following an evidence-based diet to reduce cholesterol while reducing environmental impact.

Enno Sonntag
"I'm passionate about re-designing food systems so that fungi and earthworms help us with nutrient cycling AND food production"
More about
I graduated as MSc in Agricultural Development from Copenhagen University with a thesis on the agroecology and value chain of Guatemalan cardamom, involving three months of independent fieldwork. The focus of my studies was on agroecology, plant-soil interactions, value chains and anthropology. I am fascinated by the complexity of food systems and the links between their parts.
Currently I work as a PhD researcher in the LandLessFood project at Thünen Institute of Organic Farming, which provides policy advice to the German ministry of agriculture. LandLessFood aims to build a circular food system which transforms organic residues into food and high-quality organic fertilizer during a two-step process involving edible mushrooms and earthworms. My role is to study the potential of raising earthworms as human food, using spent mushroom substrates as feedstock. Due to their high nutritional value and medicinal properties, edible mushrooms and earthworms have high potential for future human nutrition.
