Coal fly ash utilisation and environmental impact
The coal-fired power generation creates coal ash (fly ash-85% and bottom ash-15%) nearly 1 billion tonne annually. Although the coal ash was considered waste and dumped as land fill, the application of fly ash in various fields has created around 4 billion US dollar global market in 2020 with the predicted annual increase of 6%.
