Reducing the amount of waste produced always comes before recycling. We are therefore endeavoring to reduce the amount of waste on campus.
- Cloth towels in the sanitary facilities
- Posters and flyers must be approved
- Digitization of administrative processes
- Water dispenser for filling up bottles you have brought with you
- Double-sided and black and white printing
- Measures in the canteen and cafeterias of the Studierendenwerk
In accordance with the Passau system, waste is separated on campus and in offices into residual waste, paper waste and special waste (glass, polystyrene, green waste, metal and wood, IT equipment, etc.).
However, the biggest problem with waste separation on campus is the poor sorting ethic. Waste is repeatedly thrown in incorrectly, which makes sorting inefficient. We are trying to improve this with the help of education and awareness-raising. You can find tips here!
To minimize water wastage, 85% of our taps are equipped with water-efficient technology. This includes automatic switch-off and motion sensors. Toilet flushing systems have also been optimized to minimize water consumption and avoid additional flushing of the pipes.
Only cold water is used in our sanitary facilities and for cleaning processes. The showers in the sports center and the canteen are heated by solar thermal systems, which allows us to use renewable energy and minimize energy consumption. Under-counter boilers with a capacity of 5 liters are used in the tea kitchens, which ensure that hot water is supplied as needed.
The University of Passau relies on a pipe system that filters water from the River Inn and feeds it via a heat exchanger to the IT center's server systems, which are always in need of cooling.
The water is then used to irrigate the sports field, which is done 100% with water from the Inn, resulting in an impressive saving of 6000m³ per year - comparable to the average consumption of around 32 4-person households. Other green areas are only watered in midsummer if temperatures are exceptionally high.
