On the campus day of the Sustainability Week in June 2024, the Green Office was represented with a campaign on Faitrade cotton on the campus mile between OTH and the university. From 1 p.m. to 5 p.m., students were invited to discuss the topic of sustainability with us and print jute bags or their own clothing with potato stamps. The "Wall of Thoughts" with various quiz questions on the topic was also very popular and led to interesting discussions and conversations.
