The acid, alkali and solids storage facility was built in the 1960s. In addition, the company premises were expanded by 15,000 square metres through the purchasing of land. Over the next decade, the course was already set for expansion.
The first acquisition, Chemische Fabrik Dr. Reininghaus from Essen, came on board in 1971. The company joined the Penta purchasing group from Hamburg as a shareholder and invested in Reher & Ramsden Nachflg. GmbH & Co KG. Construction activity continued on the CG company premises: A solvent tank storage facility and the two-storey administration building were built. The 1970s came to an end with the establishment of the company’s own export department.
In 1986, the company took the opportunity to acquire the leased site and both modernise and expand the storage capacity. The first laboratory was established on site in 1988. SIL Lackfabrik joined the CG Group in 1989. In 1990, structural development at the site in Laatzen remained a key topic: Another storey was added to the office building, a new neutralisation facility with an underground tank was created, as well as a siding vat and the canopy over the sidings.
CG CHEMIKALIEN GmbH & Co. HOLDING KG | CG GROUP was founded in 1995 and took over the holdings of Reininghaus-Chemie, Reher & Ramsden.
