INTRODUCTION
• Coal/Lignite based Thermal Power Generation
has been backbone of power generation in India;
• Coal is likely to remain the main fuel source for
the domestic energy market over the next few
decades;
• Indian coal is of low grade having high ash
content up to 40-45%;
• Large quantity of ash is being generated at
Thermal Power Stations in the country. Cont.-

INTRODUCTION
• Gainful utilization of ash in environment friendly manner on continuous and sustainable basis is a matter of concern;
• A large number of technologies have been developed for gainful utilization and safe management of fly ash under efforts of Fly Ash Mission of GOI since 1994.
• Fly ash has now been established as a ‘Resource Material’ and ‘Useful Commodity’.
• It has now become a saleable commodity.

CONCLUSION
• We achieved the highest level of fly ash utilization of 63% in 2009-10 and it was about 56% in 2010-11;
• States and districts where thermal power stations are located need to be sensitized to the need for utilization of fly ash;
• Use of fly ash in backfilling/stowing of closed/ abandoned/running open cast and underground mines has large potential for utilization of fly ash;

CONCLUSION
• Use of fly ash in the construction of road
embankments/flyovers is gradually picking up.
However, its full potential is yet to be realized.
• Use of fly ash in the construction of railway
embankments has potential for large scale
utilization of fly ash;

CONCLUSION
• Use of fly ash based building materials, like fly
ash based bricks, blocks, tiles etc. by Govt.
agencies, both at Central and State level, is
required to be ensured.
