With the topic "Focus on Raw Materials," the lecture series celebrates its 50th anniversary. The efficient and sustainable use of natural resources is one of the major challenges of the 21st century, globally, in Europe, and also in Germany. Reasons for this include the dramatic increase in global raw material consumption, the criticality of raw materials, Germany's strong dependence on raw materials as a business location, ecological and social issues in the supply chains of global raw material systems, and resource efficiency as a competitive factor.

The two speakers of the evening, Prof. Dr. Christa Liedtke from the Wuppertal Institute and Prof. Holger Rohn (THM), have been working together for over 30 years on the necessary transformation for a resource turnaround in politics, business, education and society.

In her lecture "Consideration Consumption: When Status Determines Raw Material Consumption," Prof. Dr. Christa Liedtke, a renowned expert on sustainable production and consumption, explores the ways in which we consume in various areas of life and thus influence the consumption of natural resources. She also refers to her book "Prosperity in Times of Transition: A Reassessment for a Sustainable Future," published in fall 2025.

In his lecture, Prof. Holger Rohn will focus on resource literacy as a key to the sustainable use of raw materials. He will present key findings from the research project "Resource Literacy for Raw Material Use in Global Value Chains," which examined engineering and design degree courses nationwide. He will also discuss practical examples from the nationwide BilRess network, which, as part of the "VDI ZRE – the Competence Center for Circular Economy and Resource Efficiency," has been working on the implementation and promotion of resource literacy in all educational areas since 2012.
