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.
