UC RUSAL Sustainability report 2015



Approach DMA

One of the Company’s strategic goals is to create a closed-loop water supply system at its production facilities, in order to reduce water consumption and the amount of effluent discharged.


In 2015 the Company successfully reduced the quantity of water collected by 13.7% compared to the previous reporting period. The indicator of water used for production needs has decreased significantly (by 22% vs. 2014). This positive trend was tied to the implementation measures within the works on important water conservation at AGK at the end 2014. These measures included a project to convert the heat power plant (CHP) to a closed-loop water supply system. Outlet No. 1 was fully liquidated, and the storm sewer system was rebuilt. In addition to this goal of reducing water consumption and the amount of discharged effluent at heat power plants of AGK, the project to return conventionally clean condensate to the boiler desalinated feed-water system is also being implemented.

Water collection and use for production needs in 2012-2015, mln m3 G4-ЕN8

Water collected by source, % G4-ЕN9

Overall, the structure of water consumption at the Company by source and type of enterprises remains unchanged. The greatest amount of water is collected from surface-water bodies - 50% of the total quantity.

The Company’s alumina refineries remain the largest consumers of water. Their operations used 72.4% of the total amount of water consumed in the reporting year, which is by 1.4 points higher than last year’s indicator. The share of aluminium production in terms of the total amount of water consumption decreased from 26% in 2014 to 17.4% in 2015.

Discharge of industrial effluent, million m3 G4-ЕN22


The total amount of effluent discharged in 2015 fell by 40.8% vs. the previous period and equaled to 26.5 million m3. Effluent released without treatment decreased by 63% from 26.9 million m³ in 2014 up to 9.9 million m3. Alumina refineries remain the key contributor of discharged effluent and these refineries account for 97% of total volume of the Company’s discharges. A notable reduction of discharges was due to the implementation of measures to convert the heat power plant (CHP) to a closed-loop water supply system. Liquidation of the outlet No. 1 allowed for a reduction of the discharges by about 30 million m3 per year. All discharges without treatment are attributed to two enterprises – UAZ, BGZ.

As part of the reconstruction of sludge storage in AGK that was approved at the public hearings on the EIA (Environment Impact Assessment) materials, RUSAL has completed the construction of centralized water supply systems in the horticultural companies located in the territory adjacent to the refinery. In this regard the factory satisfied the requests of citizens to double the pipeline network. As a result, three wells were drilled in the horticultural companies, accumulating reservoirs which were mounted and more than 1,000 garden plots were connected to water supply network. The Company has also committed itself to monitor the water quality and condition of the environment in this area.

In the Middle Timan bauxite mine, Timan Bauxite placed into operation new treatment facilities in the settlement. This allowed a reduction of pressure on the equipment and an additional power reserve.
