ArcelorMittal Ostrava cuts dust emissions to a record low

ArcelorMittal Ostrava cut its dust emissions by 85 tonnes in 2012, reducing its environmental footprint to a historic low of 584 tonnes - a third of the dust emissions 10 years ago when ArcelorMittal bought the plant.


This has been made possible particularly by the implementation end 2010 of a unique dedusting fabric filter at the Sinter Plant North of Ostrava facilities. This particular equipment offers the big advantage of capturing equally effectively also smaller particles and furthermore the technology of dosage of active coke and lime reduces emissions of dioxins and carbon dioxide.

The super-efficient fibre filters can capture by 70% more of dust particles than the previous installed filters. Moreover, the mufflers installed in the giant piping have reduced the noise level of the filter by 15%, which is important as it will be in operation together with the other filters in the company round-the-clock. The efficiency of the facility is 99.9 % for dust particles PM1, PM2.5 and PM10.


Over the past decade, ArcelorMittal Ostrava has invested more than CZK4bn in its environmental programme. This has helped the company to meet the emission limits required by Czech law and the even stricter emission ceilings stipulated by the regional authority of Moravia-Silesia. "The majority of our plants already meet the strictest EU limits based on the ‘best available technique’, which will become binding from March 2016 onwards," explained Petr Baranek, chief green officer for ArcelorMittal Ostrava.

"If the European Commission approves our projects, we will be making further environmental investments exceeding CZK2.6bn by 2015," added Petr. These projects will reduce dust and NOx emissions and help improve workplace conditions. De-nitrification of the power plant and the de-dusting of the south sinter plant will account for the largest environmental investments. Expected reductions are of more than 280 tons of fugitive dust emissions, 90 tones of primary dust emissions and 808 tons of NOx emissions a year.

ArcelorMittal Ostrava is the largest steelmaker in the Czech Republic with a production capacity of 3 million tonnes of steel annually; about 50% of the output is exported to more than 60 countries worldwide. Together with its subsidiaries it employs more than 7,500 people.
