PAO Severstal, one of the world's leading vertically integrated steel and mining companies, has summed up its environmental performance in the first half of 2021.
According to the CEO of the Severstal Russian Steel Division, assets of Evgeny Vinogradov, the company systematically and in accordance with the chosen strategy reduces the environmental load in the regions of presence.
Following the results of the work of the Cherepovets Metallurgical Plant (CherMK), in six months it was possible to reduce the discharge of pollutants into water bodies by 14.4% relative to the same period last year. The decrease was achieved due to the implementation of measures for the technical reorganization of the water supply and wastewater disposal system of crushing and screening plants No. 4 and 5.
The volume of waste disposed has been significantly (43.6%) reduced due to increased sales and utilization of blast furnace sludge, reinforced concrete processing. Emission to the atmosphere has been reduced by 1.3%, which is about 2 thousand tons. The result was a decrease in the sulfur content in the Olenegorsk concentrate due to the introduction of the technology of magnetic-gravity separation of concentration. The ecological effect is ensured due to a smaller volume of coke breeze required for sintering a concentrate with a high iron content at CherMK.
Severstal continues to implement the program of measures within the framework of the federal project "Clean Air", within which the company's emissions are planned to be reduced by 66, 8 thousand tons by 2025 at CherMK, which will amount to 22.5% of the company's emissions in 2017. In 2018-2020, 13 activities were carried out within the framework of the project, most of them in coke-and-blast furnace and steel-smelting industries. At the same time, CherMK managed to achieve a reduction in emissions into the atmosphere, taking into account the construction of new capacities. This is a blast furnace complex No. 3 and the first block of a coke oven battery with coal charge ramming, "noted Evgeny Vinogradov.
In the future, by 2024, it is planned to complete a number of other activities at CherMK. This is the reconstruction of the solid fuel preparation unit at the agglomeration shop No. 3, the construction of a complex of equipment that reduces emissions from the CherMK sintering machines No. 10 and 11. The last project will require investments in the amount of about 2.5 billion rubles.
