ArcelorMittal Hamburg, a subsidiary of Luxembourg-based steelmaker ArcelorMittal, has announced that it has started using granulate from municipal waste instead of coal to produce crude steel from sponge iron and recycling scrap.
The company has been working on developing this new process for two years and now around half of the coal previously used in the electric arc furnace is being replaced by a more resource-saving alternative.
With this project ArcelorMittal Hamburg is saving an annual 3,500 tons of carbon emissions.
