Samsung said on Monday that is has collaborated with Hyundai Steel to develop a technology that allows wastewater slurry formed from chip production to be reused in steel production.

This is possible as a large part of wastewater slurry consists of calcium fluoride, which in turn is used fluorite that are used in steel production to remove impurities.

The pair succeeded in using materials from the slurry to replace fluorite for steel production at Hyundai Steel’s steel mill at Dangjin, South Korea.

The steelmaker has been importing all its fluorite from China. It has imported around 20,000 metric tonnes of the material per year, but will start replacing 10,000 metric tonnes of that will the material made from the wastewater slurry in October.

The move will allow Hyundai Steel to save costs, Samsung said.
