The company which produces about 50 million tonnes of fly ash a year at its plants, has achieved 57.3 per cent of utilisation rate as of now. Fly ash is one of the residuals generated in combustion of coal. As per the rules specified by the Ministry of Environment and Forests, coal and lignite power stations must utilise 100 per cent of the ash produced within 15 years of their commissioning. Most companies have failed to meet this requirement. About 45 per cent of the power produced in the country uses coal as feedstock.
Recently, the Central Pollution Control Board (CPCB) directed all state pollution control boards and pollution control committees to implement the notification on fly-ash utilisation from coal- and lignite-based thermal power plants by December 31.
