ArcelorMittal and the City of Zenica inaugurate combined heat and power plant

by David Fleschen

A new, combined heating and power plant has been inaugurated in Zenica, Bosnia & Herzegovina, cutting sulphur dioxide and dust emissions from ArcelorMittal Zenica by 80%. The power plant, which has been operating since the end of November 2021, provides district heating to the town, using a reliable and more environmentally sustainable supply of energy.

The power plant was built by Toplana Zenica, a joint venture between ArcelorMittal Zenica (50%), the City of Zenica (20%), and KPA Unicon and FinnFund (15% each). The plant’s new steam generators operate using coke oven gas and blast furnace waste gases from ArcelorMittal Zenica but can also operate using natural gas if necessary. Previously, the waste gases from the steel plant in Zenica were either flared or not fully re-used. The steam generated at the plant is also being used by ArcelorMittal Zenica, while air is supplied for the operation of the blast furnace.

With the new plant operational, the use of 150,000 tonnes of coal a year has been eliminated – not only cutting sulphur dioxide emissions by 80% but also cutting 18% of ArcelorMittal Zenica’s total CO2 emissions. ArcelorMittal Zenica inherited the old, coal-fired power plant from its predecessor; it continued to run the old boilers in order to provide district heating to Zenica residents, but emissions from the use of coal to fire the boilers have to date, been the largest source of SO2 emissions from the steel plant.
