Goals, Solutions and Methods

South side of the heap with sunflowers

Reduction of the saline load from the drainage ditch, Bode and Wipper, as well as reduction of the groundwater.
Improvement of landscape by recultivating of slag heaps having harmful conditions for growing plants caused by nearly 80 % proportion of sodium chloride, mainly rock salts.

By developing innovative methods, especially for “biological sealing” of old potash heaps and the precipitation run-off, and therefore, the creation of salt solution will be minimised.

The heap is covered by a water storing arrangement of three layers according to the Thuringian Heap Directive.
