Emission and Energy Consumption Dynamics
Despite the overall increase in emissions, there was a significant reduction in specific harmful substances in exhaust gases. In particular, sulfur dioxide emissions decreased by 16.74% year-on-year, particulate matter by 3.65%, and nitrogen oxides by 19.35%.
Association member enterprises reduced their total energy consumption by 6.4% year-on-year. At the same time, the total energy consumption per ton of steel increased by 4.4%, while comparative consumption rose by 2.5%. Electricity consumption per ton of steel grew by 6.2% year-on-year.
Resource Use and Recycling
The total amount of electricity consumed decreased by 0.5% year-on-year, while self-generated electricity fell by 1.4%. The share of self-generation in the energy consumption structure decreased by 0.57 percentage points, reaching 58.95%. Meanwhile, the production of clean energy increased by 46.9%, including a significant rise in wind energy generation by 415.1% and solar energy by 42.2%.
Water consumption among association enterprises increased by 3.6% year-on-year, although water intake decreased by 1.5%. Water reuse also rose by 3.6%, and the reuse rate increased to 98.49% (an increase of 0.08 percentage points). Water consumption per ton of steel reached 2.55 cubic meters, which is 10.1% more compared to the previous year. At the same time, wastewater emissions increased by 1.7%.
“The recycling rate of steelmaking and blast furnace slag, as well as iron-containing dust, remained above 99%. The use of combustible gases, including blast furnace, converter, and coke gas, exceeded 98%, and the extraction of converter gas increased by 1.7% year-on-year.”
Thus, enterprises maintain high rates of industrial waste recycling and efficient use of energy resources, partially offsetting the increase in total emissions.
