Establishing Our History
Located on the banks of the Delaware River, the Edge Moor site has been producing quality white pigment for the paint and paper markets since 1925. Initially owned and managed by the Krebs Pigment Company, DuPont acquired Krebs and the Edge Moor plant in 1929.
Edge Moor entered the titanium dioxide (TiO2) business in 1931 when it purchased a TiO2 patent-holding company, the Commercial Pigments Corporation, and began offering a line of TiO2 products. In 1951, when the demand for Ti02 surged following World War II, DuPont engineers and scientists developed an alternate, more economical and environmentally responsible "chloride process" for manufacturing the white pigment.
Introduced first at the Edge Moor plant, the new process gradually replaced the sulfate process at all DuPont Ti-Pure® plants as they expanded to meet ever-increasing demand through the 1980s.
At the height of production in 1975, the plant operated two manufacturing lines and employed approximately 850 employees. In 1980, DuPont streamlined Edge Moor's operations when one of the two manufacturing lines was shutdown.
Today, a dedicated team of approximately 200 DuPont employees and 100 contract partners safely operate the Edge Moor facility.
Together with a mining facility in Starke, Florida and TiO2 plants in DeLisle, Mississippi; New Johnsonville, Tennessee; Kuan Yin, Taiwan and Altamira, Mexico, DuPont Titanium Technologies has positioned itself as the world's largest manufacturer of titanium dioxide, producing about a quarter of the world's TiO2 pigments.
Of Note
DuPont Edge Moor also qualifies as something of an American literary landmark. From 1927 until 1929, writer F. Scott Fitzgerald and his wife leased Ellerslie, an estate located on the Delaware riverfront, where the plant now stands. A barn dating back to 1821, part of the original Ellerslie estate, still stands on the grounds of the plant.
Steel girders for the Brooklyn Bridge were manufactured on the Edge Moor site when the land housed the former Edge Moor Iron Company.
