Werra-Unterbreizbach

The Unterbreizbach site is one of four locations amalgamated in 1997 in order to form the Combination Works Werra. The size of the entire underground expanse of the sites Hattorf, Wintershall, Unterbreizbach and the Merkers Adventure Mine is comparable to the city of Munich. Unterbreizbach is situated in Thuringia, close to the Hessian border.

The Sylivinite Project

The sylvinite project at the Werra works was launched in 2005. This project utilises the underground ”rolling hole“ conveyor from the Unterbreizbach mine to the joined Hattorf/Wintershall mines, allowing cross-location mining of potash salts and ensuring capacity utilisation of the combined Werra facilities.

A partner to the region

With approximately 830 employees, among them nearly 26 apprentices and trainees, the Unterbreizbach facility is one of the most important regional employers. Potassium and magnesium production significantly contributes to the region’s economy. This facility regularly award contracts to regional sub-contactors and service providers, thereby creating an economic base for a large number of regional jobs. The site is also committed to supporting social institutions, associations and clubs.
