Expanding a highway is a herculean task, and developing the same in eco-friendly way sounds even difficult. But the Central Road Research Institute (CRRI) identified a simpler way for the same. 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.
- The Road Ministry has allowed the National Highways Authority of India (NHAI) to use the municipal waste for earth-filling during construction of highways.
- Approved by two Central agencies — Council for Scientific and Industrial Research (CSIR) and Central Road Research institute (CRRI), the NHAI plans utilisation of this solid waste material for its highway construction programme on NH-24, Meerut Expressway.
- 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.
- 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.
- The methodology suggested for use is by drying the collected municipal solid waste and passing through different sieves. The percentage passing from the 16 mm sieve contains 44 to 48 per cent of municipal solid waste which can be directly used in embankment construction.
