MMK's Environmental Investments Exceed 7 Billion Rubles in 2020
The costs of the Magnitogorsk Metallurgical Plant for environmental activities amounted to more than 7 billion rubles in 2020, of which more than 4 billion
The costs of the Magnitogorsk Metallurgical Plant for environmental activities amounted to more than 7 billion rubles in 2020, of which more than 4 billion rubles were investments in the construction of new and reconstruction of existing environmental protection facilities. All investments were made in accordance with MMK's Environmental Program, which covers all production processes. MMK's environmental investments are proving their effectiveness. Thus, the implementation of the environmental program in 2020 made it possible to reduce gross atmospheric emissions by 19.6 thousand tons compared to 2019 (to 177.4 thousand tons), and specific emissions by 4% (to 17.2 kg / ton metal products). In addition, 1.91 million tons of production wastes were used in the sinter batch as secondary material resources, and 10.055 million tons of dump slags were processed at specialized installations.
In accordance with the Environmental Program of PJSC MMK, 78 technical measures were taken in 2020 to reduce and prevent negative impact on the environment. Eight more events are underway. Among the most significant environmental protection measures of the year is the construction of an aspiration system for the foundry yard of blast furnace No. 2. Thanks to the constructed aspiration unit with a capacity of 850 thousand cubic meters per hour, dust emissions have decreased by 250 t / year, and the working conditions of the furnaces have significantly improved.
Another important area of environmental investments in the past year was the installation of dust suppression systems in open and closed warehouses of iron ore raw materials in the sinter batch preparation workshop, as well as dust suppression systems at the car dumper and crushing department of the coal preparation workshop.
In addition, it is necessary to note the reconstruction of the drainage system of a dolomite quarry in sludge storage No. 2. Within the framework of an environmental project for pumping out groundwater from the bottom of a dolomite quarry, a new extended drainage system and pumping equipment with a capacity of 500 cubic meters / hour were put into operation pumps water to sludge storage no. 2, which is a technogenic deposit. Now the water from the bottom of the dolomite quarry is used by the mining and processing industry. Thus, the dolomite quarry was completely freed from possible flooding, and most importantly, it was possible to solve the long-term environmental problem and stop the discharge of water from the bottom of the dolomite quarry into local rivers.
