Recycling of filter dusts

Companies installing an efficient recycling process do so not only to meet statutory regulations, but also to achieve economic benefits.

With thyssenkrupp Industrial Solutions as an innovative and experienced partner, what were previously just residues can be transformed into valuable secondary raw materials.

For example: one of our injection systems installed at an electric furnace steel plant reduced the ultimate amount of filter dust by 50% by injecting it into the interface of slag and molten steel and simultaneously increased the zinc content of the residual dust by 10%. The high-zinc residual dust can be utilised as a secondary raw material in the zinc industry.
