Noble Banadda International Summer School on Sustainability 2025
The 4th International Summer School on Sustainability i3s was a great success. Sixty students from 15 countries across four continents gathered at OST – Eastern Switzerland University of Applied Sciences in Rapperswil-Jona to work towards a more sustainable future and to expand their network.
The program included expert lectures, workshops, and excursions. The students engaged deeply with topics such as industrial heat pumps, solar technology, energy technology, PFAS, and sustainability management. Among other activities, they visited the production facilities of Everllence (formerly MAN Energy Solutions) in Zurich and the Werdhölzli wastewater treatment plant in Zurich.
