Recycling coal fired power station ash for mine reclamation: A climate change adaptation technology

Fly ash is a waste product of burning coal in power stations. About 800 million tons of ash is generated globally each year in the process of electricity generation. Disposal of coal ash can have adverse effects on the environment. On the other hand, a) burning coal in power stations is a major source of greenhouse gas (GHG) emissions, and b) mined lands, surface and groundwater resources are also affected by the negative consequences of mining. Examples of such effects include acid or saline drainage generated from the disposal of waste rocks and mine tailings.   

However, there is an opportunity to utilise coal ash to mitigate climate change effects and the negative impacts of mining. The overall aim of this project is to develop an innovative and integrated climate change adaptation technology to address GHG emissions, mine waste management and reclamation for the coal mining industry.

The project includes literature review, laboratory leaching tests, data analysis, and writing research report.

The outcome of this project has the potential to provide national economic, environmental, and social benefits for Australia by contributing to Australia’s adaptation to climate change. The candidate will work in a multidisciplinary team of researchers in the Centre for Mined Land Rehabilitation at the Sustainable Minerals Institute.
