GSDG recycles a hazardous waste generated during the melting of scrap steel in Electric Steel making process. The technology used (Waelz process) is rated best available technology to treat such hazardous waste material and our plant is similar to the plant operations in Western Europe and the USA, with some efficiency upgrades unique to GSDG

Steel dust is considered hazardous due to the chemical compounds found in hazardous Steel  dust like Lead and Cadmium that are present. When dust is stored on unprotected soil, these compounds can also leach into the ground and contaminate ground water.

GSDG is currently recycling the hazardous Steel dust fully into two usable products that are supplied back into the industry, making GSDG firmly part of the ever-growing circular economy cycle.

GSDG fits into the circular economy by recycling Zinc (Zn) from Steel dust that is generated from the Electric Steel making process when galvanized Steel scrap is melted. The recycled Zinc product then goes back to Zinc smelters that further convert it back to Zinc metal. The Zinc metal is then re-used back in the steel industry as a galvanizing agent on the steel. The recycling of hazardous Steel dust is vital for the circular Zinc economy.
