One in every two Indian power plants does not meet

The report, titled An Ashen Legacy, takes an in-depth look at the issue of fly ash mismanagement in India. In the last decade, coal consumption and fly ash generation from coal power plants has jumped up by almost 80 per cent. On an average, 35 per cent of fly ash remained unutilised in this decade, leading to its piling up in ash ponds.
