Reduction in water consumption at Cokemaking

The Cokemaking Department has a complicated water balance. Water is used primarily for quenching coke and for cooling gas at the Gas Processing Plant. The quality of water required for gas cooling is higher than that for quenching.

Environmental considerations for loading material at products berth

Various materials are loaded onto vessels at BlueScope’s products berth in Port Kembla harbour. The process requires consideration of appropriate management of environmental risks given the proximity to the harbour. For materials which contain fines, such as copper concentrate, even more stringent management is required, in particular around loading the material into the hold of a vessel. If the material was tipped from above the hold, dust emissions could be generated which could then fall onto docks or into the harbour.

Reduction in dust emissions from tipping rock slag

Rock slag is a very hot dry material that is generated during the Ironmaking process. This material is transported via truck from the Blast Furnace and stockpiled. Historically, dust emissions were generated when the material was tipped from the back of the truck. In order to supress dust emissions, recycled water was sprayed on the slag during tipping.

Waste and energy savings at Slabmaking

2015-WasteAndEnergySavings-1.jpg

At the completion of every Basic Oxygen Steelmaking (BOS) heat, all loose materials (steel, slag and unconsumed fluxes) in the furnace are poured out prior to commencing the next heat. This resulted in the loss of steel, which compromises process yield, and fluxes that have not fully been consumed and could be used to treat the subsequent heat.

Reducing hazardous waste to landfill at Hot Strip Mill

The process of grinding rolls from Port Kembla Steelworks Hot Strip Mill involves a recirculating water system with an additive that cools and lubricates the grinding wheel, while the water flushes away the metal shavings or debris (also known as swarf).
