Burning of waste, which releases toxic gases in the air and can cause a range of critical diseases, is continuing unabated in Calcutta, The Telegraph has found.
Heaps of dry leaves, paper cups and other waste were put on fire on the stretch opposite Judges Ghat on Strand Road on Tuesday morning. In the afternoon, a pile of wires was being burnt on Garden Reach Road, near Karbala Tank. The spiralling smoke rising up could be seen from some distance.
The state government has filed an affidavit before the National Green Tribunal stating that it has banned waste burning to maintain healthy air in the city. But this newspaper could not spot anyone from the authorities to stop waste burning on Strand Road or Garden Reach Road on Tuesday.
Environment activist Subhas Datta, who had moved the NGT about the deteriorating air quality of Calcutta, said it was the government’s responsibility to stop waste burning. “The government has given an affidavit to the tribunal that it has stopped waste burning. Merely issuing a circular is not enough. If the government says it has stopped waste burning, it becomes the government’s responsibility to see that no one is burning waste,” said Datta.
The Calcutta Municipal Corporation (CMC) and police both were responsible for preventing open burning of waste, said Debabrata Majumdar, a member of the civic body’s board of administrators who is in charge of the solid waste management department.

A senior officer of Calcutta police said they would look into the matter.
Air quality management specialists said burning waste released tiny particulate matter like PM2.5, which can enter the lungs and cause respiratory problems. “Waste accumulating on open grounds releases PM2.5, PM10, oxides of nitrogen and carbon monoxide when burnt. These make the air toxic,” said Anumita Roy Chowdhury, an air quality management specialist and executive director of the Delhi-based Centre for Science and Environment.
“During winter, this becomes more problematic as the air close to the ground becomes colder and heavier, hangs around for a longer duration than other seasons and more people end up breathing in the toxic air.”
A scientist with the state environment department said the wires were put on fire to burn the insulating material and recover the metal from inside, which is then sold. “The insulating material is made of plastic. It releases gases like sulphur dioxide and carbon monoxide. Some of the elements released are carcinogenic. Exposure to these gases can be harmful,” said the scientist.
The civic solid waste management system would need to be more robust if waste burning has to be stopped, said waste management specialists. Burning is an easy way of disposing of the waste, especially the one that accumulates on public land and is not cleaned or transported for many days.

During winter, burning of dry leaves is common as most trees shed leaves during the season. Dry leaves are gathered on the corner of a road or a ground and burnt.
The CMC is empowered to fine those found burning waste in the open. The minimum fine amount is Rs 5,000 and the maximum Rs 25,000 according to the Solid Waste Management Bye-Laws, 2020. “If we do not get to know about an instance of open burning of waste, we cannot do anything. I would urge people to inform our control room (22861212/1313/1414) if they come across any instance of open burning of waste,” said Majumdar.
The problem is plaguing New Town, too. Metro reported earlier that several New Town residents had got in touch with the New Town Kolkata Development Authority about the issue
Avishek Chakraborty, a resident of a cooperative housing society near Eco Park, said he had spotted a fire on a field opposite Eco Park on Tuesday. The field is a popular destination for birders. “I went and checked but could not spot anyone who could have started the fire,” he said.
