Innovative since 1908.

We go back a long way.

In 1908, the large water power of the Alz was the primary reason for the choice of location for the energy-based calcium carbide and calcium cyanamide production. The company at that time operated under the name Bayerische Stickstoff-Werke AG. The merger of this company with Bayerische Kraftwerke AG and Donauwerke AG in 1939 to form Süddeutsche Kalkstickstoff-Werke AG, later SKW Trostberg AG and Degussa GmbH, laid the foundations for Alzchem's current production facilities.

Our activities are characterized by the vision of being a good partner, employer, trainer and neighbor. This self-image is a good reason for us to take the responsibility for our company very seriously.
