Ecovyst Inc. is a global provider of specialized catalysts and related services, with operations spanning the United States, the Netherlands, the United Kingdom, and other international markets. The company's activities are organized into two primary divisions. Its Ecoservices segment focuses on recycling sulfuric acid for use in refinery alkylate production, as well as supplying new sulfuric acid for diverse applications such as mining, water purification, and various industrial processes. The Catalyst Technologies segment delivers bespoke catalyst products and process solutions to manufacturers and licensors involved in producing polyethylene and methyl methacrylate. These catalysts are crucial for manufacturing plastics utilized in products like packaging films, bottles, containers, and other molded items.
