THIRUVANANTHAPURAM: Fly ash, a powdery residue generated during combustion of coal, is considered a major environmental pollutant. Technological limitations have so far hampered efforts to utilise effectively the silica-rich residue from thermal power plants for production of building materials.

Fly ash is generally captured from the chimneys of thermal power plants and stored on the plant site or used as landfills along with other residual materials. Available technology permits utilisation of only 20-35 per cent of fly ash as a component in building materials.

The CSIR-National Institute for Interdisciplinary Science and Technology (NIIST) in Thiruvananthapuram has developed a flux-bonded technology that uses fly ash to the extent of 80 per cent in the manufacture of building materials…..
