KMC to set up crushing unit to turn construction waste into aggregates

02 Sep 2021 CW Team

Construction projects producing 20 tonnes of waste or more regularly would have to establish a recycling plant to convert the waste into aggregates for additional construction purposes.

The Bengal chapter of the Confederation of Real Estate Developers Association of India (CREDAI), the developers in Kolkata, has embraced the proposal and decided to execute it.

Construction waste comprises concrete blocks and damaged tiles that are not biodegradable. Rather than disposing of, they can be used for driveway pavements. The civic body would proceed to lift waste from smaller projects, though this waste would not be dumped in landfills.

KMC is building a crushing unit to transform the waste into aggregates that can be used as raw materials in construction projects.

KMC has acquired a plot in Rajarhat to set up the construction waste restoration plant. It would have the capacity to handle nearly 500 tonnes of construction waste a day. The plant would break the waste into aggregates that can be combined with concrete to construct roads.

The Rajarhat unit would witness an investment of nearly Rs 55 crore, managed by a private company to operate for ten years.

In South and South-west Kolkata, a similar plant has been set up in Garden Reach to promote waste recovery and reuse construction waste.

Many building parts/construction debris can be recycled, such as rubble and concrete in concrete items or aggregate. On the other hand, wood can be recycled as well into an engineered wood product. Metals such as copper, steel, and brass are also important resources to recycle.
