Marl Chemical Park (German: Chemiepark Marl) is an industrial park in Marl, North Rhine-Westphalia, Germany. It is the third largest industrial cluster in Germany and among the largest chemical production facilities in Europe. The site occupies over 6 square kilometers, hosts 100 chemical plants, employs 10,000 people, and produces 4 million metric tons of chemicals annually. 18 companies are based in the Park, including primary tenant Evonik Industries AG, which also owns and operates the infrastructure through its subsidiary Infracor GmbH.
Originally named Chemische Werke Hüls, the complex was built in 1938 by a consortium led by IG Farben to produce synthetic rubber and other war materials for the Third Reich. By 1942 over 5000 workers' families had relocated into new housing which transformed Marl into a company town. At the height of World War II, the Germans also used slave laborers and prisoners of war at the plant. Allied bombing heavily damaged the site in mid-1943 although full production had resumed by 1944. Near the end of the war, employees saved the plant from complete destruction under Hitler's Nero Decree and the US Army occupied it in March, 1945.
After the war, the plant operated under restrictions imposed by the Allied Control Council and by 1953 turned over to new German owners. New products such as plastics and intermediate chemicals began to be produced. Coal-mining conglomerate RAG AG became majority owner in 2007 and created a new entity Evonik Industries, with a focus on specialty and fine chemicals. In 2009, Marl Chemical Park received its current name. In 2012 a fire halted production of cyclododecatriene (CDT) for several months. The plant manufactures a substantial proportion of the world supply of CDT, a precursor to Nylon 12, which in turn led to a shortage which impacted global production of finished goods particularly in the automotive industry.
Marl Chemical Park is an anchor point on the Ruhr Industrial Heritage Trail and can be visited.
