Steel Mills generate oily millscale sludge in the rolling mill, and the landfill disposal route is expensive owing to the hazardous nature of the material.
As an alternative to landfill, a technology developed for the oil industry has been successfully adapted for processing this material in a steel mill environment.
The plant has a small footprint and can be easily retrofitted to the current mill location.
A clean scale is recovered, and can be recycled back into the steel production process. The residual oil is recovered for upgrading or sale.
