Bosnia and Herzegovina: Waste Gas Based Cogeneration in Zenica

Benefits

  • SO2   emissions reduced by 90%
  • NOx emissions reduced by 48%
  • Dust emissions reduced by 94%

Challenge

Zenica, the fourth biggest city in Bosnia and Herzegovina, is relying entirely on coal to run its district heating system. Due to this,   Zenica  is one of the most polluted cities in Bosnia and Herzegovina. To tackle this critical issue, a new gas-fired combined heat and power plant is being developed in order to completely replace the coal-fired plant.

Summary

A new joint venture “Toplana Zenica“ was set up by ArcelorMittal Zenica, the city of Zenica, KPA Unicon (Finland) and Finnfund (Finland) to implement the project.

The new plant will use waste gasses from the Arcelor Mittal steel plant. It will have an installed power of 14.45 MWe and a heat capacity of 112.5 MWth. It is expected to be operational in 2021.

Finance

The project was supported and financed by the European Bank for Reconstruction and Development (EBRD) and Taiwan’s International Cooperation and Development Fund (TaiwanICDF).

Results

The transition to the new technology will have a significant positive impact on the environment and human health. It is expected that sulfur dioxide emissions will be reduced by 90%, from 3.422,00 tonnes per year prior installation to 363,45 tonnes per year. Dust emissions will fall by 94%, from 222,64 tonnes per year to 12,82 tonnes per year. Nitrogen oxide  emissions will be cut by 48%, from 484,32 tonnes per year to 256,49 tonnes per year.
