Chlorine production plants

Where Europe's chlorine is made — every Euro Chlor member site, its capacity and the process it runs on.

Euro Chlor tracks 67 chlorine production sites across Europe, with a combined capacity of 11,940 kilotonnes of Chlorine per year. D = Diaphragm, M = Membrane. Companies shown in italics are not Euro Chlor members. The number in the first column marks each site on the map below — select a marker to see its capacity.
