LyondellBasell’s Wesseling/Knapsack Complex includes two manufacturing sites in the chemical region of Cologne/Rhineland that operate as an integrated facility. The Wesseling site began operation in 1953 and today comprises more than 2.7 square kilometres. It is LyondellBasell’s largest facility in Europe. The Knapsack site, about 15 kilometers from the Wesseling site, began operation in 1970 and is located in the Chemiepark Knapsack, near the town of Hürth.

The Wesseling/Knapsack Complex has a production capacity of more than 2.2 million tons of polyolefins a year. Two crackers, four high density polyethylene plants, two low density polyethylene plants, three polypropylene plants and one advanced polyolefins plant are in operation among the two sites. Additionally, Wesseling has its own power plant with a capacity of 470 MW, a wastewater treatment plant and a sewage incineration plant. Products from the facilities are used for films, cable and pipe coatings, fuel tanks, injection mouldings and household articles.

Approximately 1,400 employees and 170 trainees work at Wesseling, along with 1,000 contractors. Knapsack has about 150 employees.
