Together, the projects represent an investment of EUR12.4 million, the company said in an announcement Monday.

According to ArcelorMittal, one of the projects entailed installation of hybrid filtration technology installed on one of its sinter plant stacks. The company said it invested EUR3 million in the project, becoming the world’s first steel mill to employ the technology on an industrial scale.  

ArcelorMittal said the filter technology was originally developed for cement plants. But through a two-year collaboration between Danish engineering firm FLSmidth and ArcelorMittal’s research and development team, the technology was adapted to work in sinter plants.

“I’m extremely proud of the team involved in this project, which sets a new global standard for sinter plant emissions. The installation of the hybrid filter in ArcelorMittal Zenica is an important milestone in the project, which has involved our R&D team, ArcelorMittal technical specialists, and ArcelorMittal sites in Bosnia & Herzegovina and Spain. I would also like to thank FLSmidth for their highly professional collaboration on this innovative development,” said Pinakin Chaubal, ArcelorMittal’s head of process research and development.

In addition to that project, the company invested EUR4.2 million in a smokeless charging car for the coke plant. The 126-metric-ton car is designed to prevent the release of carbon dioxide as it charges the ovens in the coke battery.

Elsewhere in the mill, the company invested EUR5.2 million in equipment allowing it to produce coiled rebar. Rebar is one of the mill’s most important products.

“This will improve ArcelorMittal’s competitive edge in an important market sector,” said ArcelorMittal Zenica chief executive Biju Nair.
