CHEMISCHE FABRIK KALK GMBH

Chemische Fabrik Kalk GmbH (CFK) is a chemical plant, which is part of the K+S Group and is now a commercial company. The company was founded in 1858 as Chemische Fabrik Vorster & Grüneberg, Cöln and changed its name to Chemische Fabrik Kalk GmbH in 1892. For a time, CFK was Germany's second largest soda manufacturer and, with up to 2400 employees, was one of the largest employers in urban Cologne to the east of the Rhine. The main plant's industrial chimneys were a defining feature of the Kalk district's skyline for decades.
