Ash management

Responsibly managing waste

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.

Some 99.9 per cent 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.

Ash can be used as a cement replacement in concrete, a soil improver, an adsorbent for waste, and as flowable fill in large civil engineering projects such as highway embankments and mine site rehabilitation.

In 2015/16, CS Energy supplied 97 kilotonnes of its ash for reuse.

Monitoring ambient dust

CS Energy has established a comprehensive dust monitoring program at Callide and Kogan Creek power stations.

This program enables us to measure ambient dust levels to monitor the effectiveness of fugitive dust controls a these sites.
