 Zaporizhstal JSC is an Integrated Iron and Steel Works specializing in the production of hot- and cold-rolled sheets, tin-plates and consumer goods. Throughout the world these technological processes are connected with pollutant emission into atmosphere, water basin and the formation of industrial waste.
Zaporizhstal JSC accomplishes nature protection activity in the line of:
- Improvement of processing equipment operation (modernization).
- Commissioning of new, less power-consuming metallurgical equipment, with obligatory installation of corresponding nature preservation systems on the newly commissioned equipment.
- Modernization of the existing nature preservation equipment.
In 2000 a programme on retooling and modernization of the main equipment with maximum introduction of resource saving technologies has been made out at Zaporizhstal JSC. A significant place in this programme is dedicated to nature preservation measures. The implementation of nature preservation measures in the last 6 years has enabled reduction of emissions into atmosphere by 41%, reduction of waste water disposal by 10%, secondary use of industrial water by 86%. In 2000 reconstruction of blast furnace No.3 was accomplished. For the first time in Ukraine an aspiration unit together with a bag filter was assembled. It catches 99.5% of dust emissions during production of pig iron. The fulfillment of this measure enabled to reduce dust emission into atmosphere by 4200 t/year. The usage of units for nitrogen suppression of dust in the interbell space of all the blast furnaces enabled reduction of emissions by 11800 t/year. In November 2004 the reconstructed blast furnace No.2 was put into operation. Reconstruction costs amounted to 346 million UAH. Neither in Ukraine nor in the CIS countries can a similar furnace be found. The fulfilled complex of measures on blast furnace No.2 enabled to reduce emission of noxious agents into atmosphere by 8200 t/year. Taking into consideration the reconstruction experience of these two furnaces technical retooling and modernization of the whole blast furnace production will continue.  In September 2007 an aspiration unit (2 electrofilters) for cleaning emissions from the tail parts of the sintering machines was put into operation. Approximately 2500 tons of sintering dust is caught and returned to production.
During accomplishment of water control measures aimed at saving and rational usage of water resources the Works has gained the following results in 2000-2007:
- Reduction of return water discharge into the Dnieper River by 12.630 million m3;
- Reduction of polluting agents discharge into the Dnieper River by 8390 t/year.
In 2006 a closed complex of installations to catch the drainage water of the slag dumps in gully Markusova was constructed and put into operation. The Works is constructing a hydrochloric acid pickling line with an installation for regeneration of hydrochloric acid, which excludes discharge of neutralized pickled solution waste into the Dnieper River. Directly at the Works more than 35% of the total quantity of formed solid waste is used once more. This is metallic and metal containing waste, refractory scrap, foundry production waste, wood, etc. Constant monitory research in the areas of the industrial waste grounds and slime dump yards is carried out. For these purposes the Works spends more than 280 000 UAH annually. In the period from 2001 to 2007 Zaporizhstal JSC has spent more than 900 million UAH on construction and modernization of nature preservation installations. To control the effect of the Works on the environment a nature preservation and radiation security department has been organized. It consists of a laboratory on environmental control and a radioisotope laboratory. The environmental control laboratory continuously accomplishes monitoring of the Works' effect on the condition of all the environmental components, sanitary and hygienic control of the places of work. The radioisotope laboratory is responsible for evaluation of the radiological condition at the Works and radioisotope control of all delivered raw materials. |
