Having opened a renewed galvanic production a year and a half ago, the Kazan Helicopter Plant not only increased its productivity, but also significantly increased the environmental friendliness of the entire enterprise. New technology has reduced the volume of discharges into urban sewers by 91%. According to the Environmental Policy of Helicopters of Russia Holding, adopted in October 2016, the continuous reduction of the negative impact of production factors on the environment is one of the main environmental goals of the enterprise. Therefore, the modernization of galvanic production included construction of a new building, replacement of worn-out equipment, and introduction of new wastewater treatment technology.
