Our environmental programmes are being implemented as a matter of priority. As a result of our efforts, the project team has grown in capability. We have refined our approach to air quality in the light of both specified environmental targets and long-term environmental impacts. The level of control by the Group’s management was raised as well in 2021. We believe that these improvements in our approach will lead to concrete results as we keep adapting our strategy to become more integrated, considering the interconnected nature of the environment, our employees’ health, and the wellness of the communities in which we operate.
As part of its business operations, EVRAZ acknowledges that it generates a significant amount of air pollutants, with the potential to have adverse consequences for the environment as well as human health. Pollutant emissions are unavoidable throughout the steelmaking process. Carbon monoxide (CO), sulphur oxides (SOx), nitrogen oxides (NOx), particulate matter (dust), and volatile organic compounds (VOCs) are the key pollutants released during steel manufacturing (VOCs). Fuel combustion is the primary source of carbon dioxide and nitrogen oxides. During the blast furnace manufacturing process, large amounts of carbon monoxide are also produced. Oxidation of sulphur in ore or coking coal releases sulphide oxides as an exhaust gas component. Coal mining produces dust mostly during the transportation and storage of coal but also at all phases of metallurgical processing (sintering, blast furnace, steelmaking, rolling production). Coke manufacture is the primary source of volatile organic compounds.
In our operations, we implement the most cutting-edge technology and keep our equipment up to date on a regular basis while also closely monitoring all emissions for any violations of permitted limits. Our Environmental strategy includes air emission reduction goals, which call for a 33 % decrease in steel manufacturing emissions and a 1,5-fold reduction in dust emissions during coal transportation and storing.
Dust suppression programme in coal storages
NUMBER OF DUST SUPPRESSION UNITS
In 2021, we carried out additional activities to reduce dust emissions such as watering of roads, also with reagents, covering coal carrying trucks with sheets.
Key air emissions
Sulfur oxide (SOx), nitrogen oxide (NOx), volatile organic compounds (VOCs), and particulate matter (dust) are among our key emissions. In 2021, total air emissions from steel production decreased by 2.9% against the 2020 level due to the reduction in production at ZSMK and re-equipment of gas cleaning facilities at KGOK.
A wide range of actions and investments are being carried out by EVRAZ in order to achieve the environmental strategy objectives. These include activities and investments carried out under the framework of the Clean Air project, part of the Ecology national project in Russia. As part of the execution of the Clean Air federal initiative, EVRAZ is taking considerable steps to increase the efficiency of its gas treatment facilities.
