Environmental Expenditures
2007 saw the implementation of 70 measures aimed at decreasing and preventing the negative influence on
the environment. The most important measures are listed below:
• Revamping of desulphurization unit # 4 in the Sintering Division resulting in a decrease of sulfur dioxide
emissions by 880 tons/year, which cost USD 22.8 million;
• Revamping of an aspiration system for fines screening of Blast Furnace # 6 resulting in a reduction of solids
emissions by 200 tonnes, which cost USD 8.1 million;
• Construction of an aspiration system of the sinter stabilization unit in the Sintering Division resulting in the
prevention of discharge of 500 tons of solids, which cost USD 2.7 million;
• Construction of a gas treatment unit and aspiration system for Merz shaft kiln # 1 for lime burning resulting in
the prevention of discharge of 585 tonnes of solids per year, which cost USD 1.3 million;
• Construction of a regulated system for the circulation part of the Magnitogorsk Reservoir resulting in the
optimization of waste waters discharge to the Magnitogorsk Reservoir, which cost USD 1.86 million.
In total, OJSC MMK spent USD 745 million on environment protection in 2007.
Dynamics of Emissions into the Atmosphere
in 2003-2007
The priority of MMK’s environmental activity is protection of the atmospheric air. The strategy for diminishing
the negative effect on the atmospheric air is based on the use of the best available technologies in the
construction and revamping of the existing production facilities with simultaneous decommissioning of obsolete
and worn out equipment.
This strategy ensured a steady downward trend in atmospheric emissions (Fig. 1,2) against the backdrop of
rising production levels.
