The core business of Puri Oil Mills Limited has always been mustard oil. With over 80 years of core competence in the domain, the company carries the mantle of “The Mustard Specialist” with pride. In addition to mustard oil and several value-added variants, the company also manufactures mustard oil-cake used as cattle fodder. Further, in a move that represents both – a pioneering backward integration initiative as well as a key diversification strategy – the company has forayed into the area of clean, green renewable energy by setting up small hydro power projects.
