Refinaria Nacional de Sal S.A. was established in 1949 in Cabo Frio, on the Northern coast of Rio de Janeiro.

Owing to the extremely favorable aspects of local geography -- flat land, year-round sunshine, constant winds and low rainfall, as well as the proximity of Arararuama lake, with a salt concentration rate even higher than that of the sea -- the area Is ideally suited for salt production in Brazil.

The raw material came from Ponta do Costa ponds which provided the brine for Refined salt production. The purchase of vacuum evaporation equipment was the turning point for the most innovative salt processing operations in the area.

In 1951, Cisne production was started. The processing equipment, with production capacity of 50 tons of vacuum refined salt a day, was imported from Germany. As Cisne grew to become the leading brand in the Brazilian salt market, the refinery also innovated in packaging by introducing the one kilo plastic bags for everyday domestic consumption.

Production continued at full speed while profits were continuously reinvested in the plant. In 1968, as Ponta do Costa production was no longer capable of meeting demand, the refinery acquired Salina Viveiros. Between 1972 and 1978, 90,000 sq. meters of concrete ponds were built to stock 350,000m3 of brine. In 1974, production increased again as the first of the new evaporators started operating on Plant II. Six years later, in 1987, Plant III was built to produce the new hydro mechanically milled Clipper Salt brand, a new option in salt products.

In 1987, a processing unit was built for the production of low-sodium salt, Cisne Light. And in 2003, a new facility was built to process Liquid Salt, sachets and the shakers known as Ovo (Egg) and Cozinha (Kitchen). A new automatic fluidized bed dryer started operating in 2004, to achieve better drying control of final products and improve energy savings. With electronically controlled operations, it was the very first equipment of its kind to be installed in a salt processing company in Brazil. Also in 2004 a new laboratory for physical and chemical as well as microbiological analysis was built, ensuring the highest standards in analysis results.

In 2005 another step forward: a new process was developed to produce high grade and purity salt for hemodialysis solutions.

In 2006 the company´s industrial restaurant was remodeled to allow in-house professionals to prepare and serve meals in temperature-controlled and pleasant environment.

Between 2008 and 2009, a new packaging system was installed to achieve higher productivity and better environment conditions in the packaging area.

To offer the highest purity salt, the Refinery uses state of the art technology and follows strict quality and control procedures in both its processes – multiple-effect vacuum thermal evaporation and hydro mechanical milling with coarse salt washing.

Current staff is 600 employees and production capacity is 20,000 tones/month. The Refinery is today the only Company in Brazil to produce a type of salt for every end use.
