    Landfills to help NHAI in construction


    The National Highways Authority of India (NHAI) got on board to use segregated garbage in  road construction. The plan has been finalised to take off in November.

    Various experts were also roped in to find ways to segregate and utilise the 130 lakh tonne of garbage gathered at landfill sites in the national Capital.

    The plan, envisages using garbage in building new roads and expansion of roads for connecting national highways and rural areas of Delhi.

    A Memorandum of Understanding (MoU) was signed between the EDMC, Union Ministries of Urban Development, Road Transport and Highways, and the National Highways Authority of India (NHAI) on Thursday.


    Earlier, the NHAI had come forward to use the garbage for the 2-km stretch of the Delhi-Meerut highway. However, the authority had reservations about the cost of the whole exercise.

    According an expert, roads, particularly green-field expressways, require massive quantity of soil or base material as they are built on embankments.

    NHAI has now decided to undertake the development of Meerut expressway from Dasna in Ghaziabad on this new alignment.

    Most of the Eastern Peripheral Expressway (EPE) is being built on embankment, which needs high volume of base material.

    An official of East Delhi Municipal Corporation (EDMC) said that the garbage after leaving unattended for five years turns to soil like substance.

    All the municipal solid waste contains about 65 to 70 per cent of soil components which can be reused in embankment construction after segregation from the municipal solid waste.

    He further said Council of Scientific and Industrial Research (CSIR)’s Central Road Research Institute (CRRI) conducted a study.

    It involved collecting 70 tonnes of five, ten and 15-year-old municipal solid waste from different locations of Ghazipur Landfill site.

    It was found that it had soil components which can be used in road construction.

    In deliberations about the mounds at Bhalswa and Okhla landfill sites, it was decided to undertake their greening after grading their slopes in an engineered manner. The work at all the three sites shall be under the guidance of the experts to take care of any contingencies and long-term effects.

    The DJB CEO said the Lt-Governor about possible solutions for more efficient forms of disposal of silt by stocking it in geo-tubes and de-watering the same along the banks of the existing major drains.

    At around 50 metres, the height of garbage heaped at the Ghazipur landfill site in Delhi is barely 20 metres short of Qutub Minar, the world’s tallest brick minaret.

    Commissioned in 1984, it has long outlived its utility but continues to take in over 2,500 MTD (metric tonnes daily) of garbage from East Delhi Municipal Corporation areas every day.

    The facts are ominous, Delhi produces over 8,500 MTD of solid waste, but all three of its dumping grounds, with a collective capacity of 4,600 MTD are operating beyond their saturation point, at the “risk of human lives”, according to official documents.

    According to the DPCC, the waste produced by the civic bodies is as follows: North corporation: 3,100 MTD, South: 2,700 MTD, East: 2,200 MTD, New Delhi Municipal Council 300 MTD and Delhi Cantonment Board 70 MTD.

    But what is alarming is that waste generation is expected to go up to 15,000 MTD by 2020, according to the economic survey report.
