NHAI is going green by implementing the use of fly-ash i.e. upto 30% of earth filling in the Eastern Peripheral Expressway and using other slag materials elsewhere. Municipal Corporation of Delhi (East) had earlier approached NHAI to make use of waste at Ghazipur Landfill site, whereupon NHAI had commissioned analytical study through CRRI. NHAI plans utilization of this Solid Waste Material in place of substantial replacement of natural earth for its highway construction program on NH-24, i.e. Meerut Expressway. To allay the doubts of Concessionaires and to encourage them to utilize this waste, NHAI has offered to indemnify the Concessionaires for the stretches where this waste material shall be tried. This initiative of NHAI is commendable and shall promote the construction of Green Highways in the country.
