In 2019, ArcelorMittal Kryvyi Rih expenses on environment amounted to 562.9 UAH mln.
Every year, the Company allocates funds for implementation of major investment projects, including repair of fixed assets intended for environment protection purposes. For instance, in 2019, the repair of draft equipment was performed, as well as construction of two-stage gas cleaning plant within reconstruction of rotary kiln №3 in Lime and Refractory Shop. ESP was replaced with a modern bag filter here. Lime stone heater and modern automation were installed to reduce consumption rate of natural gas. Resulting from all the work done, dust emissions were reduced to 90%.
The main investment projects include construction of two modern continuous casters and modernization of Sinter Plant №2. Within reconstruction of Sinter Plant №2, new modern gas cleaning plants manufactured in Denmark were constructed and commissioned from tail parts of sinter strands Nos.3-4 and from junction houses of primary mixing block and sinter returns. Automatic environment monitoring system was implemented on GCP from sintering zone to control emission volumes in real-time. In total, three out of six sinter strands were revamped already, and environmental modernization of the fourth sinter strand began in the end of last year. Resulting from the reconstruction, dust emissions per each of six sinter strands will reduce by 250 tons a year.
The Company is also gradually proceeding with reconstruction of tailings Obiednane and Myroliubivske, construction of the first stage of tailing Tsentralne and their circulating water supply. These facilities are used for disposal of beneficiation waste. Additional useful vessels for disposal of beneficiation tails were created to avoid usage of additional land resources.
In the period between 2006-2019, ArcelorMittal Kryvyi Rih invested 6.8 UAH bln for environment protection purposes and constructed more than 120 highly effective gas cleaning plants. From the moment of plant privatization total air emissions were reduced by 42.7%, sewage – by 78.4%, waste disposal – by 23.7%.
