Chennai: Union of the Ministry of Environment, Changes in Forest and Climate (MOEF & CC) have directed the National Highway Authority (NHAI) and other institutions to use fly-ash for road construction within a coal radius or lignite-based thermal power plant.
NHAI officials, however, said they remained on paper because the power plant would not come to supply free material, including transportation, according to the guidelines.
The ministry has published directions to encourage institutions to use alternative materials for road construction activities.
This direction has been issued for all construction institutions, given the availability of abundant flying ashes in power plants in this country.
The ministry has also issued guidelines for using fly ash in the road embankment and elevated work.
The ministry, in its order, stated that it was deemed necessary to promote the use of flying bricks, blocks and tiles on national highways.
Physical requirements, general quality and dimensions of all bricks of ash, blocks and tiles will meet relevant Indian standards.
The same thing has been communicated to the Secretary of the Secretary of the State and / UTS, the main official of the Ministry of Public Works, Road Construction and the American Highway Department and UTS, in addition to the NHAI chairman.
According to guidelines, thermal power plants and lignit must supply free fly ash.
They must bear the transportation costs too.
A senior Nhai official, citing guidelines, said some power plants did not comply with the guidelines.
However, they have approached power plants to use Fly Ash for construction activities and in several incidents, they have paid transportation due to the scarcity of the earth.
NHAI officials have approached NLC and several other power plants within a 100 km radius to get Fly Ash for six Poonamallee-Waljapet road project lanings.
“Because there is disagreement with a power plant, we have written to the Coal and Mine Union Ministry to direct power plants to strictly comply with the guidelines,” the official said.
Sources in the electricity sector say the type of financial crisis they do not allow them to supply free fly ash for road construction.
