The Mumbai Metropolitan Region Development Authority (MMRDA)
is discussing a proposal for recycling of construction and demolition
waste being generated as a result of the ongoing construction of metro lines in
the city as construction material.
There are two
metro corridors currently under construction in suburban areas of Mumbai -
Metro 2A and 7, and four more corridors — 2B, 4,5 and 6— on which construction
is likely to begin by the end of 2018. According to estimates, close to
1.61 lakh cubic metres of demolition waste is expected to be generated during
the construction of these projects.
“The waste
generated can be recycled into reusable raw materials for building activities.
This will not only be environmentally beneficial but will also help us save
costs,” an official from MMRDA told Indian Express.
According to
the proposal, the metro projects are currently generating more waste than the
quantities specified in the Rules for Management of Construction and Demolition
Waste, 2016. The proposal states that “it is mandatory for MMRDA to initiate
the processing of C&D waste generated for the metro projects.”
At the moment, the contractors
involved in these projects are expected to dispose of the waste in landfills on
the outskirts of the city. If the new proposal is adopted, it could save them
approximately Rs 29.53 crore as they would not have to incur any cost on
transporting the waste to the dump sites.
The Metropolitan Commissioner of
MMRDA was quoted in the IE report as saying that this plan will not be
implemented immediately, since the waste produced at present, is not much.
“Once we have more projects that require
construction materials like coastal road then we can reuse the material there.
Not much waste is being generated from the two corridors that are under
construction,” he said.
