The S4S board consists of TU Delft students who manage the organisation on a part-time basis. Every year students are motivated to commit themselves to the mission of this foundation. The S4S board of 2020/2021 consists of the following persons:


Jelske verkuijlen - chair

Hi! I'm Jelske, the new chair of S4S. Two years ago, I had a nightmare. I saw a polar bear that couldn't go home because of the molten ice. When I woke up I knew for sure that I wanted to use my technical knowledge to solve the climate crisis. We need a big change in the mindset of our generation, and that is exactly where I can help as a board member of Students4Sustainability. Apart from S4S, I'll stay busy with my Masters in Multi-Machine Engineering and I work as a CAD designer for a satellite company for several hours a week. When I finish my education, I want to contribute to making the car industry more sustainabile.

Josefien van den Berg - secretary

Hi everyone! My name is Josefien and this year I'll be the secretary of S4S 14! Apart from taking notes, e-mailing, writing documents et cetera, I'll be studying for my minor in Music Studies and I'll finish my Bachelor's degree in Clinical Technology. Sustainability has become a gradually bigger part of my life in the last couple of years, but it was always limited to my own lifestyle. Eating vegetarian or vegan, buying less clothes and limiting waste are really fun things for me, but with Students4Sustainability I'm hoping to contribute to a much larger goal. I'm really looking forward to meeting interesting people next year, learning a lot and inspiring other students that sustainability isn't just important, it's also fun!

If you have any questions or ideas that you'd like to share, don't hesitate to e-mail me at!


berend tideman - treasurer

Hi! I am Berend, 21 years old, and this year I am the treasurer of S4S. In addition to keeping money matters in order, I am also working on my second year of Mechanical Engineering. I am enormously motivated to start working at S4S this year because I believe that we as technical students have a responsibility to use our technical knowledge for a more sustainable world. We can make the difference. There is still a lot that people don’t know and there will be much more to learn in the future, so it is associations like S4S and others that raise awareness that plant the seed of sustainability on people’s minds and helps it sprout.

sieb rodenburg - commissioner of projects

Hi everyone! I’m Sieb and i’m responsible for this year's projects. I think our generation stands for one of the most fun and challenging tasks people have ever met; the energy transition. The idea of being on our way to a self sustaining world sometimes makes me feel like i’m in a revolution. I think we as TU Delft students have a crucial role in this revolution. This is why I want to inspire as much students as I can to use their knowledge for the world of tomorrow.

peter zilch - commissioner of external affairs

My name is Peter Zilch and this year I’ll be responsible for all external affairs of S4S. Last year I was part of De Groene Pint committee. After reading and comparing all the sustainable initiatives of the Dutch Student associations throughout the country, I discovered that with the right motivation, willingness to change and some effort it doesn’t have to be that hard to reduce your impact. Making the business world more sustainable for me, starts with awareness about your impact both in your own company and spread out over your whole supply chain. Students will play a mayor part in making business more sustainable. This year I’ll be committing myself to making sustainability within business visible for students, so that when they start working in a few years they’ll also have a positive impact on the business world.

eline franke - commissioner of activities

Hi everyone! My name is Eline and I'll be responsible for this year's activities of Students4Sustainability. I'm really looking forward to organizing events that will make Delft students become more thoughtful of sustainability. Last year, I finished my Bachelors degree in Architecture and though there certainly was attention for sustainability, it was often viewed as something necessary instead of something fun, interesting and important! Ever since I was little, I've been amazed by the beauty of our planet and this feeling has grown all the more when I started studying. That's why I want to strive with S4S to keep the earth this way, and I'm convinced TU Delft students can and will play a big roll in this! I'm looking forward to using my creativity to increase Delfts enthusiasm about sustainability!
