Covestro says its new facility can reduce carbon dioxide compared with existing processes.

Covestro has opened a chlorine plant in Tarragona, Spain, that it says is the world’s first large-scale facility to use oxygen depolarized cathode technology. The process, developed with the engineering firm Thyssen- krupp Nucera, uses 25% less energy than traditional chlor-alkali electrolysis, Covestro says. The plant cost more than $200 million and will supply chlorine for the firm’s production of methylene diphenyl diisocyanate, a polyurethane raw material.
