For more than 70 years – gaining, applying and sharing our experience

Since the end of the 1940s, the engineering competence for the East German potash and rock salt industry par excellence has been established in Erfurt. From 1952 as KALI-INGENIEURBÜRO Erfurt, and since 1956 at the headquarters in Arnstaedter Strasse 28, ERCOSPLAN continued this tradition from 1992 as a management buy-out foundation after the political change in Germany.

Today, with 200 employees at five locations, we are active worldwide both for the potash and rock salt producers themselves, for investors in new mineral salt projects or as independent experts for mining and environmental authorities or also for financial institutions and supervisory bodies of international financial trading houses as well as for national or international arbitration courts.

What do we do?

We do everything about salt!

Mineral salts – whether solid or in dissolved form – are our profession, as raw materials for potash fertilizer production and other applications in the chemical industry or as host rocks for the underground storage of chemical waste or radioactive waste repositories.

Thematically, our services range from exploration and evaluation of mineral salt resources, to extraction and processing, including the planning and optimization of the related processing facilities, to environmental protection during ongoing production. Both for decommissioned potash and rock salt mining operations and for other mining sectors, we advise and plan for the subsequent use and closure of mines including the related monitoring and risk assessment.

With regard to planning maturity, our service starts with the formulation of an innovative project idea and ranges from early planning and cost studies through classic feasibility studies to the final planning stages, including all aspects of environmental protection and sustainability as well as permit management and construction and installation supervision.
