Residual waste materials from power plants

In the past, we were able to successfully use ashes prepared in our process in different forms and for various projects: 

Backfilling of residual cavities of the former surface mining pits Lochau and Peres

Soil conditioning during the construction of the A72 motorway (approx. 130,000 metric tonnes of brown coal filter ash)

Direct backfilling or backfilling of thick matter in underground cavities, such as e. g.:

Project Quantity
Comp. Geomin Lengefeld - stowing of Oberscheibe chalk mine 210,000 metric tonnes
DBE Deutsche Gesellschaft zum Bau und Betrieb von Endlagern für Abfallstoffe; backfilling object: Ultimate disposal zone for radioactive waste, Morsleben (ERAM) starting in 2007 approx. 11.000 m3

Co-incineration of sewage and biological sludge

Project Quantity
Sewage and biological sludge for the MIBRAG power plant in Deuben 100,000 metric tonnes
municipal sewage sludge for co-incineration in the power plants Lippendorf and Boxberg of Vattenfall Europe Generation 40,000 metric tonnes/year
