The Neckar (German pronunciation: [ˈnɛkaʁ] ) is a 362-kilometre-long (225 mi) river in Germany, mainly flowing through the southwestern state of Baden-Württemberg, with a short section through Hesse. The Neckar is a major right tributary of the Rhine. Rising in the Schwarzwald-Baar-Kreis near Schwenningen in the Schwenninger Moos conservation area at a height of 706 m (2,316 ft) above sea level, it passes through Rottweil, Rottenburg am Neckar, Kilchberg, Tübingen, Wernau, Nürtingen, Plochingen, Esslingen, Stuttgart, Ludwigsburg, Marbach, Heilbronn and Heidelberg, before discharging on average 145 m3/s (5,100 cu ft/s) of water into the Rhine at Mannheim, at 95 m (312 ft) above sea level, making the Neckar its 4th largest tributary, and the 10th largest river in Germany. Since 1968, the Neckar has been navigable for cargo ships via 27 locks for about 200 kilometres (120 mi) upstream from Mannheim to the river port of Plochingen, at the confluence with the Fils. From Plochingen to Stuttgart, the Neckar valley is densely populated and heavily industrialised, with several well-known companies. Between Stuttgart and Lauffen, the Neckar cuts a scenic, meandering, and in many places steep-sided, valley into fossiliferous Triassic limestones and Pleistocene travertine. Along the Neckar's valley in the Odenwald hills many castles can be found, including Hornberg Castle and Guttenberg Castle in Haßmersheim; the now-mothballed Obrigheim Nuclear Power Plant and the active Neckarwestheim Nuclear Power Plant are also located there. Traditionally the fertile plains have been intensively used for agriculture and its steep valley sides as vineyards.

BASF SE (German pronunciation: [beːaːɛsˈʔɛf] ), an initialism of its original name Badische Anilin- und Sodafabrik (German for 'Baden Aniline and Soda Factory'), is a European multinational company and the largest chemical producer in the world. Its headquarters are located in Ludwigshafen, Germany. BASF comprises subsidiaries and joint ventures in more than 80 countries, operating six integrated production sites and 390 other production sites across Europe, Asia, Australia, the Americas and Africa. BASF has customers in over 190 countries and supplies products to a wide variety of industries. Despite its size and global presence, BASF has received relatively little public attention since it abandoned the manufacture and sale of BASF-branded consumer electronics products in the 1990s.The company began as a dye manufacturer in 1865. One of its employees, Fritz Haber, worked with Carl Bosch to invent the Haber-Bosch process by 1912, after which the company grew rapidly. In 1925, the company merged with several other German chemical companies to become the chemicals conglomerate IG Farben. IG Farben would go on to play a major role in the economy of Nazi Germany. It extensively employed forced and slave labor during the Nazi period, and produced the notorious Zyklon B chemical used in The Holocaust. IG Farben was disestablished by the Allies in 1945. BASF was reconstituted from the remnants of IG Farben in 1952. It was part of the German economic miracle, and has since expanded considerably. It has received modern criticism for its poor environmental record.At the end of 2019, the company employed 117,628 people, with over 54,000 in Germany. In 2019, BASF posted sales of €59.3 billion and income from operations before special items of about €4.5 billion. Between 1990 and 2005, the company invested €5.6 billion in Asia, specifically in sites near Nanjing and Shanghai in China and Mangalore in India. BASF is listed on the Frankfurt Stock Exchange, London Stock Exchange, and Zurich Stock Exchange. The company delisted its ADR from the New York Stock Exchange in September 2007. The company is a component of the Euro Stoxx 50 stock market index.
