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.
Kogan Creek Power Station’s waste ash is piped to the neighbouring Kogan Creek Mine and stored in an ash cell and at Callide Power Station it is stored in an on-site ash dam.
CS Energy is a strong advocate of recycling ash – from the more traditional offtake into cement products to any opportunity that leads to the beneficial use of ash. We recycle approximately 11 per cent of the total ash that we produce by selling it to end users through long term ash sale arrangements.
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.
