In its 2019 report, the UN Environmental Programme predicts an annual global increase in demand for primary mineral materials of 5.5 %. According to the report, sand and gravel resources are the second largest resource, after water, to be mined and traded. In this context, the recycling of mineral waste is urgently needed. The activities of mineral material recycling not only ensure a sustainable approach to nature, but also guarantee a reliable supply of important construction materials. At the same time, the impact on the landscape is reduced – in two ways, because mineral recycling reduces the loss of natural space through the extraction of primary resources and at the same time avoids the use of land for the disposal of material that can actually be reused.
