After the mining there are new chances
The extraction of Neuburg Siliceous Earth does not end with raw material recovery for HOFFMANN MINERAL. From the very beginning, responsible landscape restoration has been an integral part of the process – aiming to harmonize nature, usage, and biodiversity in the long term.
Even when the mining of Neuburg Siliceous Earth is carried out with high respect for the environment, it nonetheless represents an intervention into nature. This is why HOFFMANN MINERAL since several decades prior to the startup of a new mining pit develops plans for the later reintegration of the area in the pertinent ecosystem. In cooperation with survey authorities, Forest Office representatives, Nature Protection specialists and ground owners, economical and ecological interests are brought in accordance. The refilling of all layers is only carried out with natural materials. Already during the excavation the valuable mold will be stored separately in order to be used later on for the recultivation.
With great dedication, new biotopes are created based on recultivation and renaturation measures. Recultivation restores cultural landscapes after raw material extraction, while renaturation promotes nutrient-poor soils for natural development. Only the structures of water bodies, areas, and soils are predefined. In this way, habitats for rare animal and plant species, as well as new usable land, are created – a chance to enhance biodiversity!
When opening an open-pit mine, the top humus layers are removed and temporarily stored after clearing the area. Specialized machinery and the planting of vegetation on the heaps ensure that soil quality is preserved. After the extraction process, the mine is refilled with natural materials, the humus is reapplied, and its fertility is enhanced through root systems, shrubs, and additional humus from regional sources.
Subsequently, the soil is prepared for future use with cover crops and planted according to the landowners' specifications. HOFFMANN MINERAL maintains the areas for several years before they are returned. Additionally, retention basins are created, which serve as shallow water biotopes, providing valuable habitats for rare animal and plant species.
