Basis of utilization
With the sponsored pilot project Bleicherode, “Development of a procedure for recultivation of potash residual heaps”, through the German Federal Foundation for Environment in Osnabrück, the scientific basis for heap recultivation was made. From 1993 until 1996, a research project was implemented under supervision of the K-UTEC Sondershausen and the cooperation of the university Göttingen, the technical university Clauthal, the comprehensive university Kassel as well as the Dr.Schaef+Partner office Freiberg.
Legal basis of heap recultivation is the business plan approved by the mining authority and the „Thuringian Potash Heap Directive“.
It’s your waste-we can use it!
For the biological sealing of the heap, the following materials (LAGAZ 1.2) can be used:
- Non-contaminated diggings
- Building site rubble
- Foundry waste sand
- Street sweepings
- Paper sludge
- Bedding residuals
- Ash and soil substrate
- Gypsum waste
