A second hybrid filter has been installed in the sinter plant, cutting dust emissions from sinter machine no. 6 below 10 mg/Nm3, a level which is well within European Union standards as well as being far below the 50mg/Nm3 legal limit in Bosnia & Herzegovina.

In 2017, ArcelorMittal Zenica became the first steel plant in the world to have industrial-scale hybrid filtration technology installed in its sinter plant.

The filter technology was developed through a partnership between Danish global engineering company FLSmidth and ArcelorMIttal’s R&D team, with a team of seven researchers and six technicians working on the design and testing stages of the project.

The ceremony also marked the completion of the installation of the secondary dedusting system in the  BOF Steel plant, a €5.1m project. The process of putting the entire system into operation, and testing the equipment, is currently underway and on course for completion before the end of 2020. ArcelorMittal Zenica worked with Italian engineering company Ekoplant on the project.

The company is also in the process of installing new gas boilers for a new combined heat and power plant that will provide greener energy to the city of Zenica, as part of a joint venture with the city of Zenica that is being built with EBRD financing. This will result in an 80% reduction in SO2 emissions from the plant, which is Zenica’s sole external provider of heating during the winter.

With 2,350 direct jobs and more than 12,000 indirectly dependent on the company for employment through more than 400 local supplier companies, ArcelorMittal Zenica is one of the country’s biggest economic generators.
