Earlier on Friday, PK Mishra, principal secretary to the prime minister, expressed concern over the slow progress in clearing landfill sites and delays in implementing waste-to-energy projects in the national capital.

Chairing a meeting of the High-Level Task Force to address Delhi’s air pollution, Mr Mishra called for stronger enforcement of dust control at construction sites and better waste management.

He directed the agencies to prevent the open burning of waste and to promote greening and paving of road areas to reduce dust.
