Our position as the European market leaders in the field of acid tar remediation is based on more than 15 years of experience. All in all, we have remediated over 450,000 metric tonnes of acid tar and acid tar residues during that period. These are some of our projects:

Disposal and utilisation of construction waste

  • Major building site, City-Tunnel Leipzig (disposal of more than 1 million metric tonnes of mineral waste)
  • Disposal from the construction sites of Deutsche Bahn AG through framework agreement.
  • Remediation / recultivation of slopes: Vergissmeinnicht pit, Nottagebau surface mining Ammendorf, Espenhain screen wall

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.:

  • Comp. Geomin Lengefeld - stowing of Oberscheibe chalk mine, approx. 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)
    Backfilling of approx. 11,000 cubic metres, starting in 2007

Co-incineration of sewage and biological sludge

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