In another major initiative towards environmental conservation and scientific recycling of construction wastes, the Delhi Metro Rail Corporation (DMRC) has commissioned a new facility at Rohini for the recycling of Construction and Demolition (C&D) waste generated from construction work. The plant may also be used by other agencies for recycling their construction related waste.

A specialized firm, M/s IL&FS Environment will manage the plant. The new facility was inaugurated by DMRC’s Managing Director, Dr. Mangu Singh at Ranikheda in Rohini in the presence of Sh. Mahesh Babu, Managing Director, IL&FS Environment and other senior officials. It has crushing, screening and separation facilities which would maximize waste management and ensure zero/minimum land filling. The plant has a total capacity of processing 150 tons of waste per day.

The construction waste generated by DMRC is generally dumped at pre designated sites identified and approved by the government. To utilize this waste, this new facility has been constructed. This is one of the many initiatives taken by DMRC for the preservation of the environment.

The C&D waste transported from DMRC’s locations will be recycled into green products like aggregates, manufactured sand, concrete bricks, tiles, paver blocks, kerb stones etc.  Use of recycled aggregate reduces the consumption of fresh stones and sand, thus conserving natural resources and helping in reducing sand mining. The wet technology adapted at the plant will help in minimizing process residues as well as dust and noise pollution. The C&D waste will be processed to recover and recycle about 95% of incoming C&D waste. The project will also help in saving scarce urban land in addition to processing waste. Similarly, other agencies involved in construction will also be able to get their waste recycled here.

The total system would be in conformity with C&D waste rules and other applicable rules and guidelines. The crushing would be done in such a manner that noise and dust pollution is controlled as per environmental norms.

The C&D wastes which can be recycled are cement concrete pile heads, re-bars, concrete blocks, broken bricks, cement plaster, rubble, broken stones, soil, sand, gravel, demolished building material like railing, frames, roofing, broken glasses etc.

DMRC has always been very conscious about its responsibilities towards the environment. It is the first Metro system in the world to bag green certification for all its premises including depots and residential colonies.  IL&FS Environment is also considered a pioneer in C&D waste management and has two C&D waste management facilities operating on Public Private Partnership (PPP) model at Burari and Shastri Park.
