CRRI for using Ghazipur site waste to widen NH-24

New Delhi: In a move that could see usage of solid waste from Ghazipur dumping site for embankment construction of NH-24 (Meerut Expressway), the Central Road Research Institute (CRRI) has found that 65-75% of segregated waste can be utilised for such work. Use of solid waste is expected to reduce the huge mounds of waste in the dumping yard and will come as a relief considering that the capital city is struggling to find space to dump 7,000 tonnes of daily municipal waste.
The CRRI report has recommended construction of an experimental test track and monitoring of it for two years before large-scale field application.
However, in an official release, NHAI said it plans utilisation of the material for widening of NH-24 and construction of greenfield Meerut Expressway. “To allay the doubts of concessionaires and to encourage them to utilise this waste, NHAI has offered to indemnify the concessionaires for the stretches where this waste material shall be tried,” it said. The authority will also write to environment ministry to allow usage of solid waste material in lieu of fly-ash wherever feasible.
TOI on December 29 had first reported how test reports submitted by Delhi municipal authorities to road ministry showed treated waste is fit for building embankments and base of roads.
CRRI conducted the study after collecting 200 tonnes of municipal solid waste from three different locations from Ghazipur landfill site and these were five, 10 and 15 years old.
