During our production process, large amounts of waste heat are generated, especially in the electric arc furnace. Up to now, this heat has not been utilised and ends up in the environment. Our idea is to generate hot water from the energy content of the waste heat and use it to supply regional consumers with district heating. For example, residential and commercial areas in the neighbourhood could benefit from this. This heat supply could be realised in a climate-friendly way without additional expenditure on fossil fuels. According to initial estimates, the waste heat potential is around 60 gigawatt hours per year.

We have commissioned a feasibility study to analyse the viability and exact energy potential of this project. The waste heat sources could, for example, be utilised through an internal hot water circuit, which transfers the heat via a heat exchanger to a district heating circuit with hot water. Technical requirements would include the construction of a heat exchanger with circulation pumps, a heat storage tank to compensate for load fluctuations and new district heating pipes. Initial study results could be available by the end of this year.
