West Bengal: Govt to push for eliminating single-use plastics
Facing the challenge of generating a staggering 1,000 tonnes of plastic waste daily, the West Bengal government is stepping up its efforts to combat plastic pollution, with a strong emphasis on eliminating single-use plastics (SUPs) across the state. Initiatives range from installing cloth bag vending machines to imposing complete bans in ecologically sensitive and newly developed tourist destinations. On World Environment Day, Additional Chief Secretary (Department of Environment) Roshini Sen reiterated plans to install subsidized cloth bag vending machines in market areas. 'One can take a cloth bag in exchange for a small amount of money. These bags are highly subsidized and can be used multiple times,' she stated. The government has already successfully declared the Gangasagar Mela a 'full plastic-free mela' and has completely banned plastic bags in ecologically sensitive tourist places like the Sundarbans. Furthermore, plastic is entirely prohibited at the recently inaugurated Digha Jagannath Dham. 'Our aim is to stop Single Use Plastic (SUP) completely,' she said, adding that civic bodies have the directive to impose fines for non-compliance, and the department can 'be a little strict' when necessary. Annually, the state produces 330,000 tonnes of plastic waste, with Kolkata municipal areas alone contributing 400 tonnes per day. 'If we really recycle it well, the same waste can be turned into wealth,' Sen added. The state has registered 30 plastic waste processing units, including facilities in Digha and Dhapa. The ongoing efforts are being conducted under the theme 'Beat Plastic Pollution,' with a specific focus on 'Plastic Waste and Endangered Ecosystem.' State Environment Minister Chandrima Bhattacharya, addressing school students, called for their participation in stopping plastic use to save the environment. 'It is important to move ahead and accept modernity, but we must also be cautious of what we are passing on to our next generation. So, be responsible citizens,' she urged. Kalyan Rudra, chairman of the West Bengal Pollution Control Board (WBPCB), highlighted the pervasive nature of plastic pollution. He explained that burning plastic below a specific temperature emits harmful gases and cited alarming research findings: 428 plastic particulates are found in every kilogram of dry sediment in the Hooghly River, and the atmosphere contains approximately 5,700 microplastics per cubic meter around each person.

Pollutants order changes post Covid pandemic: Cooking, industry emissions on PM2.5 rogue list
1 2 3 4 Kolkata: On the occasion of World Environment Day, the West Bengal Pollution Control Board (WBPCB) released a comprehensive report revealing how Kolkata's air pollution sources had significantly shifted in the years following Covid-19 pandemic. The analysis, drawing on two landmark studies — NEERI's pre-pandemic source apportionment study (2019) and TERI's recent post-pandemic study (2025) — shows a perceptible change in sectoral contribution to two key pollutants: PM10 and PM2.5. Significantly, only these two pollutants breach the national ambient air quality standard (NAAQS). Earlier, releasing the report, Bengal environment minister Chandrima Bhattacharya, WBPCB chairman Kalyan Rudra, additional chief secretary of the environment department Roshni Sen, former VC of Bengal Engineering and Science University (BESU) Ajay Roy, and WBPCB member secretary J P Meena emphasised how plastic pollution plays havoc with our lives and biodiversity. WBPCB chairman Kalyan Rudra declared an award for students for collecting and responsible disposal of plastic wastes through its network of 5,000-plus schools in Bengal. According to the findings, coarse particulate matter (PM10) in the city saw a decrease in dust-related emissions, from a dominant 57.3% in 2019 to 43% in 2025, suggesting possible improvements in street cleaning and construction regulation. However, this was offset by rising contributions from household cooking (from 13.3% to 18%), industry (5.9% to 12%), and vehicular tailpipe emissions (8% to 13%). Notably, refuse burning and secondary sources, which were negligible in 2019, emerged as more prominent contributors in 2025. Fine particulate matter (PM2.5), which poses graver health risks due to its ability to penetrate deep into the lungs, now sees an increased contribution from industrial emissions (7% to 21%) and cooking (27.9% to 29%). Dust emissions halved (from 24.7% to 12%), while secondary aerosols — a complex mixture formed through chemical reactions involving vehicle, industrial, and power plant emissions — came into sharp focus, now accounting for 13% of PM2.5. This rise suggests a growing influence of chemical pollutants in the city's atmosphere. The report also notes that while policies such as the introduction of BSVI vehicles and the uptake of electric mobility helped reduce PM2.5 from tailpipes (23.5% to 20%), older vehicle fleets continue to be significant emitters of PM10.

Bengal plans 800-km ‘green wall' along Jharkhand border
In an ambitious move to combat pollution, Kalyan Rudra, Chairman of the West Bengal Pollution Control Board, announced a project to create an 800-km 'bioshield' — a forested area that would act as a 'Green Wall' — along the Jharkhand border to intercept pollutants entering Bengal. He also highlighted Kolkata's recent recognition as one of the country's cleanest metropolises. The announcements came at a special session, 'Fostering Climate Consciousness — Business and Beyond', hosted by the Bharat Chamber of Commerce on the eve of World Environment Day. The Green Wall will be a green corridor of forest cover along the State's 800-km northwestern border with Jharkhand. The bioshield will start from the Jharkhand border and extend up to Birbhum and Dinajpur districts of West Bengal. The trees will take over a decade to grow. 'We are proceeding in phases,' Mr. Rudra said. 'It will intercept a part of these pollutants entering Bengal. It will take about a decade to grow, but when fully grown... people who go to see the Chinese wall will come to Bengal to see a green wall that we have been able to create.' He also encouraged businesses to participate in this plan. The proposed bioshield, Mr. Rudra said, is part of a larger effort to reduce in-situ pollution and mobilise industry participation in sustainable practices. The panel also underscored Kolkata's recent achievement of being recognised as one of the cleanest metropolises in the country, a result of collaboration between the pollution control board and Kolkata Municipal Corporation. However, Mr. Rudra also recognised that winters in Bengal are marked by heavy air pollution, unlike the relatively clean air during the summer and monsoon seasons. The session on the eve of World Environment Day brought together multiple experts on pollution to emphasise the need for on-ground action and the urgency to implement change beyond symbolic gestures. Swati Nandi Chakraborty, environment consultant, drew attention to the hazards of plastic pollution and the need for bioplastics as a viable, sustainable alternative to combat the rising issue of microplastics and nanoplastics, which are known to impact humans and animals alike. 'We have hardly heard about bioplastics,' she said. 'But they could work hand-in-hand to create a techno-socio-economic response to plastic waste.' Citing the harmful health effects of microplastics, from respiratory issues to gastrointestinal damage, Dr. Nandi called for strict local implementation of plastic regulations and mass advocacy for sustainable materials, including awareness programmes. She also insisted that policy-level changes can help bring about a bigger impact on pollution levels and plastic usage. Aniruddha Mukhopadhyay, Professor in the Department of Environmental Science at the University of Calcutta, highlighted that behaviour change requires community level engagement, especially from students to bring about bigger impact and long-term change. 'New pollution-control technologies are being implemented that are being monitored by regulatory agencies. Regulatory agencies are doing very well in that direction and many more things can be done, and there is a genuine consciousness amongst the common people that it is very important,' Mr Mukhopadhyay said. The experts reiterated that the business community has a pivotal role to play, saying climate conscious business in the contemporary world is crucial for sustainable growth. But the experts also stated that real climate consciousness must extend 'beyond boardrooms' into homes, schools, and streets. As Mr. Rudra reminded, 'No pollution control board or chamber can achieve success alone. It should be a people's movement where every citizen comes forward.'

PM 2.5 in 2024-25 winter Kolkata's best since 2019
Kolkata: This winter brought a breath of relatively cleaner air to Kolkata, with the city recording its best particulate pollution levels since 2019. Data from a six-year analysis by West Bengal Pollution Control Board (WBPCB) painted a picture of cautious optimism. Dec 2024 saw the PM2.5 level drop to 73 µg/m³, the lowest in recent years, followed by 77 µg/m³ in Jan 2025. These are the best readings in Kolkata for these months since the beginning of the dataset in 2019. However, even with the notable dip, the PM2.5 concentration during the peak pollution months of Dec and Jan continued to exceed the national safe limit of 40 µg/m³. PM2.5 refers to fine particulate matter with a diameter of 2.5 microns or less. They are tiny enough to penetrate deep into lungs and enter the bloodstream, contributing to respiratory and cardiovascular illnesses. Winter months typically see a spike in PM2.5 due to a combination of lower wind speeds, temperature inversions, and increased emission from vehicles and biomass burning. While the reduction in average concentration levels signals progress — likely driven by stricter vehicular emission norms, cleaner fuels, and increased public awareness — the city is still far from achieving truly breathable air, experts warned. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Her body cannot endure this level of pain; please help her. Donate For Health Learn More Undo The peak pollution year was 2020-21, coinciding with the post-lockdown reopening of industries and transport after the first Covid-19 wave. During that winter, Dec and Jan saw exceptionally high PM2.5 levels of 140 µg/m³ and 131 µg/m³, respectively. Since then, gradual improvement was observed. Summer and monsoon months of April-Sept generally showed cleaner air, aided by factors like rainfall. July recorded the lowest pollution levels across all years, dropping to 13 µg/m³ in 2023-24. However, the summer period appears to have hit a plateau, with no significant air quality gains in recent years. The data highlights that while regulatory efforts and better public awareness seem to be contributing to declining winter pollution, Kolkata's air quality remains vulnerable because of constant construction activities and increasing automobiles. Experts warned that without sustained intervention, like promotion of green transport, clean energy, and emission controls, the progress may be short-lived. "The pandemic gave us a brief moment of cleaner air but the real challenge lies in making those improvements permanent. The transboundary pollution often undoes our clean air efforts, particularly in winter months. Winters still pose health risks, especially for vulnerable populations," said WBPCB chairman Kalyan Rudra.
