Filter dust recycling

Companies installing an efficient recycling process do so not only to fulfil statutory regulations but also to obtain economical benefits.


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


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