The travelling exhibition “Wertvolle Erde” is dedicated to geological raw materials and the way they are formed, and to the prospecting, extraction, use and recycling of those reserves which the earth has to offer.
The exhibition answers many questions: How are geological raw materials formed, and over what period of time? How are they searched for and found? How and where are they extracted today? What methods can be applied to make rational, effective use of deposits? Where are geological raw materials, especially ores, used in industry, and how can these raw materials be reused in a way that makes sense?
