Severstal Reduced Discharges from CherMek in H1 of 2021
Russian steel maker Severstal has summed up its environmental performance in the first half of 2021. According to Evgeny Vinogradov, General Director of the Severstal Russian Steel Division and resource assets, the company is systematically and in accordance with the chosen strategy reducing the environmental burden in the regions of its presence. As a result of the work of the Cherepovets Metallurgical Plant, in six months, it was possible to reduce the discharge of pollutants into water bodies by 14.4% compared to the same period last year. The reduction 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 disposed waste was significantly (by 43.6%) reduced due to an increase in the sale and disposal of blast furnace sludge, and the processing of reinforced concrete. Emissions into the atmosphere have 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 provided due to a smaller volume of coke breeze required for sintering concentrate with increased iron content at CherMK.
Severstal continues to implement the program of measures within the framework of the federal project "Clean Air", under 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, within the framework of the project, 13 activities were carried out, most of them in coke-and-blast furnace and steel-making industries. At the same time, CherMK managed to achieve a reduction in atmospheric emissions, 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,
In the long term, until 2024, it is planned to complete a number of other activities at CherMK. This is the reconstruction of the solid fuel preparation unit in the sinter 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.
