A century of experience

Van Mannekus & Co BV, founded in 1904 in Rotterdam and a daughter company of the Possehl Erzkontor Group from Lübeck (Germany) since 1991, developed into the leading expert on the processing of MgO and emery.

The company developed into the leading manufacturing and trading company for caustic magnesium used in the flooring and ground wheel industries and is one of the largest traders of caustic calcined magnesite. The brand names FloorMag® and StoneMag® are well-known in the industry.

The factory in Oudenbosch is currently the biggest emery production plant in Europe, with a capacity of 10,000 tons per year.
