About Chemische Fabrik

Chemische Fabrik GmbH operates as a trading company for chemicals and fertilizers and continues the name of the historic Chemische Fabrik Kalk GmbH. The latter was founded in 1858 in Cologne by Julius Vorster and Hermann Julius Grüneberg as Chemische Fabrik Vorster & Grüneberg, Cöln and renamed Chemische Fabrik Kalk GmbH in 1892. The plant in Cologne-Kalk produced potassium nitrate, soda, potassium chloride, nitrogen and phosphate fertilizers, ammonium sulfate, sal ammoniac, magnesium sulfate as well as sulfuric acid and nitric acid. Grüneberg developed the world's first industrial process for processing raw potassium salts (carnallite). In 1960, Salzdetfurth AG (later Kali und Salz, today K+S) took over the company, which was at times the second-largest soda producer in Germany and employed up to around 2,400 people. BASF decided to close the plant as of December 31, 1993; afterwards the production facilities were demolished and the site remediated. Production no longer takes place today.
