The Marl Chemical Park is a fully integrated site that is one of the largest of its kind in Europe. Operated as part of the ChemSite Initiative through a partnership between the public and private sectors, this 650 hectare (6.5 km2) site is home to 30 major chemical companies such as Evonik Industries, Sasol, Rohm and Haas, and Vestolit that operate approximately 100 chemical plants here. Pipelines and rail, road, and water transportation links are used to bring in basic feedstocks such as ethylene and propylene, and a newly upgraded Vestolit chlor-alkali facility produces feedstock for the company’s own vinyl production chain as well as chlorine that is supplied to other users at the site. Altogether, more than 4,000 different types of chemicals are produced at the Marl Chemical Park, ranging from high volume materials such as styrene, polystyrene, 1-buten, acrylic acid, ETBE, and PVC to speciality products like polyamides and polyesters, plasticizers, surfactants, elastomers, and latices.
Each year, a total of 4 million tons of chemicals produced at the site are shipped to customers all over the world, with approximately 400,000 tons going out by rail, 2.4 million tons by road, 900,000 tons by water, and 300,000 tons by pipeline. Overseeing all of these operations is Evonik Site Services, the site operator and service provider. The company employs some 3,400 people who tend to the site’s railway, port, pipeline, storage, and other logistics facilities as well as such mission critical infrastructure as power stations, water treatment facilities, and incinerators.
