Ash is a by-product of the combustion of coal at CS Energy's Callide and Kogan Creek power stations.
These power stations produce ash in two forms: fly ash, which has the consistency of talcum powder, and furnace ash, which is like coarse sand.
Responsibly managing ash waste
Some 99.9 percent of the ash created at our power stations is collected in a manner that allows it to be recycled or stored on site in ash dams or ash cells.
Each year, CS Energy sells waste ash produced at our power stations – in FY2018 we sold 121 kilotonnes of ash for reuse. Ash can be used as a cement replacement in concrete, a soil improver, an absorbent for waste, and as fill in large civil engineering projects such as highway embankments and mine site rehabilitation.
CS Energy continues to explore new opportunities for recycling ash from our coal-fired power stations.
Monitoring ambient dust
CS Energy has a comprehensive dust monitoring program at Callide and Kogan Creek power stations.
Through this program we measure ambient dust levels and consult with our neighbours about our dust control.
