NTPC has developed infrastructure at the Rihand project in Uttar Pradesh to transport fly ash in bulk to cement plants, located at distance, at a cheaper cost.
The development is in line with NTPC’s commitment towards 100 percent utilisation of fly ash from power plants. The first rake of 59 BOXN type of railway wagons carrying 3,450 metric tonne (mt) of fly ash was flagged off from NTPC’s Rihand super thermal power station for ACC cement manufacturing plant, Tikaria, U.P. located at a distance of 458 kms. During the 2019-20, almost 44.33 mt of fly ash was utilized for various productive purposes, being 73.31 per cent of the ash generated. Moreover, company is looking at new avenues of fly ash management like fly ash based geo-polymer road, use of bottom ash as replacement of fine aggregate (sand) in cement concrete. Also, NTPC has plans to set up fly ash classifier unit for export purposes.
