On Tuesday, morning, civic workers burnt trash near the residential area in sector 12, Koparkhairane close to the open nullah. The residents said they had to close their windows to prevent the smoke from entering their flats. The morning walkers also complained about the air pollution due to the burning of green waste.

Datta Pol, a resident of Kanchan Janga Society, said, "It has been a regular practice of the civic sweepers to burn dry leaves on the roadside. This pollutes the air. The civic body must ensure that the conservancy workers do not burn biomass waste in residential areas."

Bhavna Zaveri, a housewife from sector 26,Vashi said, "The smoke from the burning trash in Koparkhairane spread to the neighbouring area of sector 26 as well."

Another resident Mahesh Mukkanwar of Kalash Udyan society in sector 12, said, "The civic garbage trucks only collect household waste in the morning. The sweepers make small bonfires of garbage lying on the roadside." Another resident Dr Sameer Mande said, "Inhaling the fumes from burning trash can be harmful and may cause respiratory ailments over a period of time."
