The shortage of fresh fly ash has led more and more industry stakeholders to turn their attention towards the centuries of landfilled fly ash. To date, billions of tonnes of fly ash have been landfilled. 'Harvesting' fly ash from these landfills makes some industry experts confident that this waste-product could have a second wind in cement.

What is Fly Ash? Fly ash, a byproduct from coal-based thermal power plants, is abundantly available in India. Estimates show that more than 100 million tons of fly ash are produced annually from around 83 major coal-based power stations. A small fraction of this is fruitfully utilized. Fly ash is a solid fine-grained material resulting.
