The sustainability walk on campus
The Sustain Tour provides an overview of how the University of Kassel contributes to the 17 Sustainable Development Goals (SDGs) of the United Nations. Interesting information on contact persons, facilities, projects, research and teaching offers, start-ups, cooperation partners and groups and initiatives in the field of sustainability can be accessed via QR codes.
17 SDG goals = 17 listening stations
The 17 Sustainable Development Goals (SDGs) of the United Nations are presented in a vivid way at 17 stations, which are identified by colorful information boards and seating cubes and are spread across the entire campus. The special thing about it: at each station, interviews with researchers, institutions and initiatives related to sustainability can be listened to via a web app. The interviewees talk about their work and how they specifically contribute to achieving the SDGs.
Making of: Environmentally friendly implementation of the Sustain Tour elements
The Sustain Tour concrete seating cubes were made from cement-reduced concrete (eco-concrete) with the support of a student project at Faculty 14, within the Department of Construction Materials and Construction Chemistry from the Department of Civil and Environmental Engineering. As part of the course Building with inorganic binders (Dr. Alexander Wetzel), a group of students developed a low-CO₂ concrete and produced cement-free concrete seating cubes under strict sustainability criteria.
The cement-free concrete produced specifically for this project has a significantly lower carbon footprint than conventional concrete. The students carried out a series of tests and trials under the guidance of concrete laboratory managers in order to determine the properties of the fresh and hardened concrete and, in particular, its durability.
The wooden seating surface was designed and built by the university's joinery department.
