Ecolab subsidiary Nalco has started construction of a dry polymer production facility at its Garyville complex in Louisiana, US.
The plant will produce dry polymer products used to remove contaminants from wastewater, increase production in the paper industry and recover minerals in the mining industry.
Louisiana Governor Bobby Jindahl said: "Ecolab decided to reinvest in Louisiana because of the track record of production success the company has had in St. John the Baptist Parish, and most importantly, because Louisiana has some of the best workers in the world."
The 300,000 square feet facility will increase space at the Garyville complex to one million square feet.
Jim Seifert, Ecolab executive vice president, said: "The new dry polymer facility further strengthens our relationship with the community and the State of Louisiana, and we look forward to opening this facility and providing our customers with another innovative product solution."
Construction of the facility is scheduled to be completed in December 2012.
Nalco's Garyville complex produces industrial water treatment products, such as corrosion and scale inhibitors for use in boilers and cooling towers, as well as process chemicals products for petroleum, papermaking, mining, steel, power generation, food and beverage, metalworking and aluminium refining industries.
