Administration building of the Ruhr-nitrogen AG (today tax office Bochum-Süd) in Bochum

The Ruhr-nitrogen AG , headquartered in Bochum was built in 1952 from the 1895 founded the German Ammonia Sales Association (Davv) and was one of the largest fertilizer producer in Europe. Ruhr-nitrogen AG was taken over by Norsk Hydro in 1985 .

history

In 1895, the DAVV was founded by several companies that processed coke by- products (including Dr. C. Otto & Comp. , The mining company Hibernia ) in order to control the trade and prices of ammonia products. To underpin the effectiveness of the “artificial” fertilizer, research into plant growth was started on test fields. It finally succeeded in replacing the fertilizer previously used in agriculture in the form of imported Chile saltpeter and guano with its own products. Gradually, almost 50 companies joined the DAVV sales organization, so that it was finally renamed in 1947 as Kohlenwertstoff-AG . In 1952, due to AHK law No. 27 of the Allied High Commission for the unbundling of the coal and steel industry of May 16, 1950 , this was split into the three companies Ruhr-nitrogen AG , BV-Aral AG , and sales association for tar products AG . In addition to trading, Ruhr-nitrogen later also took over the fertilizer production facilities.

In July 1957, in order to intensify research, the Hanninghof on the outskirts of Dülmen was purchased as a test and research station with the possibility of field experiments. In 1968 around half of the nitrogen fertilizer produced in Germany comes from Ruhr-Nitrogen - a total of around 4 million tons of fertilizers and chemical products are produced annually.

In July 1974, the federally owned Veba  AG took over the majority of the shares and in 1978 finally became the sole shareholder. Veba's chemical subsidiary Chemische Werke Hüls sold Ruhr-nitrogen to the Norwegian company Norsk Hydro in 1985, and the crop protection sector was sold to the US company DuPont . Norsk Hydro renamed the Ruhr-nitrogen AG in Norsk Hydro Ruhr Aktiengesellschaft and later Norsk Hydro Deutschland GmbH , with which the company name (company) ceased to exist. In 2003 the Hydro group spun off the fertilizer business ( Hydro Agri ) into the separate joint stock company YARA .

today

Built in 1956 and bought in 1984 by the state of North Rhine-Westphalia for DM 10.4 million, the administration building of the former Ruhr-nitrogen on Bochum's Königsallee now houses the Bochum-Süd tax office, while the Hanning-Hof in Dülmen is still used as a research center and is the headquarters of YARA Administration in Germany.

The Ruhr sulfuric acid plant in the Hofstede district of Bochum , which was shut down in 1973 and then operated by GMU (Gelsenberg-Mannesmann Umwelt GmbH, later a company for material recovery and environmental protection) as a waste recycling plant (especially car tires), was finally shut down and renovated in 2008 .

The former nitrogen plant of Hibernia AG in Herne with a capacity of 570,000 t / a (coordinates 51 ° 32 '  N , 7 ° 12'  E ), later Plant II of Hüls AG, was shut down in 1990 and completely demolished. The site is now the Hibernia business park.

The plant in Langelsheim near Goslar (coordinates 51 ° 56 ′  N , 10 ° 20 ′  E ), which has been used by WiFo / IG Farben for the production of highly concentrated nitric acid for explosives since 1937 , which later produces 300,000 t / a of fertilizer Established base was closed in September 1986.

The former WiFo / IG Farben plant in Embsen (coordinates 53 ° 11 ′  N , 10 ° 22 ′  E ), which was built in 1937 for the production of highly concentrated nitric acid for explosives and since 1947 for fertilizer production (including as Norddeutsche Chemische Werke AG , Salzgitter Chemie , Nord-Chemie ) with a capacity of 370,000 t / a was shut down in 1989 - although the production of nitric acid was not stopped until 1992. The "old work" is now to be partially used as a museum.

The plant in Brunsbüttel, built in 1972 (coordinates 53 ° 55 ′  N , 9 ° 13 ′  E ), which has a convenient deep-sea port on the Kiel Canal and a rail connection, still exists today under the Yara.
