A powerful judicial remedy for waste management
India is the biggest plastic polluter in the world, according to a new study published in Nature, releasing 9.3 million tonnes (Mt) annually. This is equivalent to around a fifth of global plastic emission. Plastic emissions, according to this study, are defined as material (which includes both debris and open plastic burning) that has moved from managed or mismanaged systems (in which waste is subject to a form of control, however basic contained state) to the unmanaged system (the environment; uncontained state) with no control.
Evidence of an underestimation
The report goes on to say that India reports that its dumpsites (uncontrolled land disposal) outnumber sanitary landfills by 10:1 and, despite the claim that there is a national collection coverage of 95%, there is evidence that official statistics do not include rural areas, open burning of uncollected waste or waste recycled by the informal sector. This means that India's official plastic waste generation rate (approximately 0.12 kilograms per capita per day (kg cap−1 day−1) is probably underestimated and waste collection overestimated. According to this study, the plastic waste generation rate for India of 0.54 kg cap−1 day−1.
The alarming situation vis-à-vis plastic waste in the Indian Himalayan Region was highlighted in an Opinion page article in this daily, 'Mountains of plastic are choking the Himalayan States' (March 4, 2024). A salient point was the lack of data regarding the quantum and the quality of waste and the capacity to deal with plastic waste in this region.
Waste generation data regarding the total solid waste and plastic waste in the country is given in the Central Pollution Control Board's annual reports on implementation of Solid Waste Management Rules 2016 and based on data supplied by State Pollution Control Boards (SPCB) or Pollution Control Committees (PCC). In turn, these are based on data supplied by the municipal bodies in the respective States/Union Territories. There is nothing in any of the reports regarding the methodology adopted by SPCBs or PCCs or municipal bodies or any waste audit which explains how the figures have been arrived at. It is important that the methodology employed by whatever agency that is gathering the data is put out in the public domain and faces third party scrutiny so that the systems we create or propose to create for waste management are commensurate with the quantity and the nature of the waste that needs managing and processing. There is no accounting of waste being generated in rural India it seems, which comes under panchayati raj institutions, and also for a vast stretch of the country which does not come under the jurisdiction of any institutions of local self-governance.
The Supreme Court of India has observed that environmental protection is not only a regulatory obligation but also a constitutional imperative aimed at safeguarding the fundamental rights of individuals and preserving ecological balance.
There is an urgent need that we have cogent, reliable data about waste generation and its composition in the country. We also need to have data regarding the infrastructure that the country has built over the years to deal with the management and processing of this waste. This infrastructure could be geotagged to help in tracking. Every local government, whether in an urban or in rural area (they are the pivot of waste management as in the legal mandate in the country), has to be mandatorily linked with a material recovery facility (MRF), recyclers of various waste streams, extended producer responsibility (EPR) kiosks and sanitary landfills.
To operationalise EPR, all producers, importers, and brand owners (PIBOs) that have a legal obligation collectively can form kiosks across the country to gather waste from all local bodies. These kiosks could be set up depending on the quantum of waste expected, the geography of the area, and ease of access to these kiosks and other relevant factors. This is so that every urban and rural local body in the country has easy access to these kiosks where all waste that is covered under EPR can be deposited. PIBOs can employ people to segregate their waste at such kiosks so that various segments of waste can be taken care of according to the mandate of the law. This is not a simple exercise. But it is not not impossible either if there is a plan.
We need to know how much waste is being generated where and how it is being managed. As India is a technology powerhouse, it is time that we leverage this to solve our problems and set an example for the world.
Court verdict on tanneries
On January 31, a Division Bench of the Supreme Court gave a very heartening verdict in the form of continuing mandamus to ensure that the pollution caused by tanneries in Vellore of Tamil Nadu is reversed by employing necessary remediation programmes. The Court has constituted a committee that needs to report in four months on the compliance of the order. The Court itself has justified the need to ensure compliance. The Bench said, 'violations occur while various Supreme Court directives and environmental norms are flouted, and the schemes or plans framed by the Government remain on paper, failing to achieve any meaningful results. Thus, this Court, being the custodian of fundamental rights, must come to the rescue of the affected individuals/families and ensure that persistent wrongs are rectified and justice is actually done'.
It is absolutely imperative that constitutional courts in India adopt this approach and deal with matters of waste management in the same spirit. Justice will only be done in these matters when compliance with orders is ensured in a time-bound manner.
Focus on the polluter
The Court in the same matter reiterated that 'the polluter pays principle' casts absolute liability on the polluter for the harm caused to the environment and extends not only to compensate the victims of pollution but also the cost of restoring the environmental degradation. Remediation of the damaged environment is part of the process of sustainable development, and such a polluter is liable to pay the cost to the individual sufferers as well as the cost of reversing damaged ecology. The Court has held that when there is a violation in compliance with the environmental laws (be it a result of engaging in activities directly involved in causing pollution or from a failure to take steps to curb pollution and restore the environment or violating any terms of licence granted by any State or central authority and acts detrimental to the environment, the effect of which causes or is likely to cause degradation of the environment), then the deeming fiction of polluting the environment becomes applicable. The polluter is not only liable to payment of compensation but has also to restore the environment.
Therefore, while the liability is clear, the process of determining an equitable compensation amount is fraught with challenges, as it must account for both the tangible and intangible damage inflicted on the environment and the affected communities. In this matter the Court applied the Government Pay Principle, and it is for the government to pay compensation to the affected individuals/families and recover the same from the polluters, until the damage caused to the ecology is fully reversed.
It is time that the waste management system in the country is also held accountable to millions whose health is impacted by the land, water and air pollution caused by unmanaged and mismanaged waste all across the country.
In fact, continuing mandamus could be the way forward to deal with pressing environmental issues to ensure compliance.

Bengaluru stampede tragedy: What science tells us about crowd control
Several stampedes have occurred in India just this year. On 15 February, a stampede at the New Delhi Railway Station killed 18 people, including many passengers who were travelling to the Maha Kumbh Mela in Prayagraj, which also experienced a stampede in January. At least 30 people died at the religious gathering as crowd management measures failed. Published in Nature in February, the study analysed video footage from Spain's San Fermin festival, popular for its running of the bulls event held in July every year. Researchers found that when crowds reached a certain density, spontaneous and rhythmic patterns emerged. Termed 'collective oscillation', the crowd self-organised, and began forming involuntary large-scale, wave-like patterns. New Delhi : A stampede during Royal Challengers Bengaluru's victory celebrations outside the Chinnaswamy Stadium claimed 11 lives Wednesday, and injured several others. Stampedes are recurring tragedies in India, but a study by French and Spanish researchers suggests that patterns emerge in tightly packed crowds. The correct identification of these oscillations, and monitoring via drones and CCTVs, can ensure crowd control and safety during mass gatherings, it says. While these events haven't undergone any scientific scrutiny, the observations from the study in Nature have the potential to help organisers prevent the next stampede. In an interview to The New York Times, France-based physicist Dr. Denis Bartolo, who co-authored the study, said that he placed cameras across the plaza to film the movements of the crowd below. At first, it seemed 'erratic, chaotic, turbulent'. But Bartolo and his team applied fluid dynamic techniques to 'measure the flow of a material by inspecting its direction and velocity'. Similar orbital motions—which took 18 seconds to complete in that particular plaza—were detected right before a stampede that took place at the 2010 Love Parade in Duisburg, Germany, the study shows. The researchers found that above a critical density of people, these oscillations emerge almost organically, without any external guidance. These oscillations are caused by random interactions between people—a slight nudge to gain space, a shuffling of feet, or even an adjustment of posture. These 'odd frictional forces' provide a sort of collective quality to the crowd, leading the mass to exhibit properties similar to fluids. By mapping where and when oscillations start, organisers of mass events can use monitoring tools, like drones or CCTVs, to identify areas in the crowd before a disaster occurs. If these circular motions are detected, the relevant action can be taken, thereby averting stampede-like situations. A similar study, published in Nature in December 2024, studied how crowds behave in marathon events, where groups of runners move in the same direction. Particularly, the goal was to 'investigate the impact of race staff on crowd dynamics'. Similar to ripples in water, the simulations showed wave-like patterns coursing through the crowd. 'We can very clearly observe that starting from the initial homogeneous and random velocity of particles, density and velocity patterns are formed,' read the report by researchers from Indian Institute of Technology-Banaras Hindu University. But an NYT report warned that real-world applications may be limited—'It's one thing to have a well-lit venue filmed with high-quality cameras. But grainy nighttime security footage, for instance, may not reveal the telltale circular movements.' However, recognising that patterns form right before stampede-like events is the first step to building effective crowd management techniques.

Donald Trump's USA may witness massive exodus of scientists, biggest beneficiary will be China, warns report
Scientists in the USA have warned that Donald Trump administration's move to cut spending on science will set off a brain drain. Scientific leaders say that's risking the way American science has been done for years and the preeminence of the United States in their fields, as per a report. China and Europe are on hiring sprees. An analysis by the journal Nature captured the reversal: Applications from China and Europe for graduate student or postdoctoral positions in the United States have dropped sharply or dried up entirely since President Donald Trump took office. The number of postdocs and graduate students in the United States applying for jobs abroad has spiked, NYT News Service reported. A university in France that created new positions for scientists with canceled federal grants capped applications after overwhelming interest. A scientific institute in Portugal said job inquiries from junior faculty members in the United States are up tenfold over the past two months, as per the report.

How the technology industry is trying to meet its climate goals
A team of researchers from Microsoft and WSP Global has published a groundbreaking study in Nature demonstrating that advanced cooling methods like cold plates and immersion cooling can cut data centre emissions by 15-21%, energy use by 15-20%, and water consumption by 31-52% compared to traditional air cooling. The life cycle assessment, led by Husam Alissa of Microsoft, Mukunth Natarajan, and Praneet Arshi of WSP, among others, also provided actionable insights to help the Information and Communications Technology (ICT) industry meet its climate goals. 'Our [life cycle assessment] has shown that reducing data centre energy use through advanced liquid-cooling technologies will lead to marked reductions in data centre environmental impacts,' the authors wrote in their paper. Electronics versus rising temperatures Electronics heat up like crowded kitchens: billions of microscopic switches (transistors) are like cooks working nonstop, bumping into each other while flipping electrical dosas (data). The tighter they are packed — that is smaller the chips are — or the more tasks they handle, the more they collide and create heat, just like a packed kitchen gets hotter, needing fans and ACs to cool down. A laptop is like a kitchen with one burner: a simple fan suffices. A data centre is like a thousand laptops working at full speed in a single room, generating heat like a massive bonfire compared to a single candle. Without cooling, the intense heat will melt the hardware in minutes. Heat slows down electrons, like runners in thick mud. If the chips get too hot, they may malfunction or altogether fail. Cooling keeps them running smoothly, ensures a longer lifespan and fast and reliable performance, and prevents heat damage. Just like an athlete needs water to stay sharp in a race, electronics need efficient heat removal. Race to cut emissions In data centres, cooling consumes nearly as much power as computing, like an AC fighting oven heat in a busy kitchen. To curb climate change, the ICT industry needs to cut emissions by 42% by 2030 (from its 2015 levels). Data centres need greener designs that use less energy and water, and have lower greenhouse gas emissions to help meet global climate goals and keep warming below 1.5°C. Urgent upgrades to energy, efficiency, and cooling are critical. Chips are also getting smaller, faster, and more energy-efficient, like upgrading your phone every year without draining the battery faster. As the demand for cloud services increases, so must data centre capacities and heat mitigation strategies. Ice packs and oil baths Two prominent cooling techniques have emerged as viable alternatives. Cold plates, also known as direct-to-chip cooling, are small heat exchange modules equipped with microchannels to enhance heat transfer. Think of a cold plate like an ice pack strapped to a feverish forehead, but for computer chips. It sits directly on hot components, with small coolant-filled channels absorbing heat into tiny channels filled with coolant. When it becomes warmer, the coolant — such as 25% polyethylene glycol and 75% water — flows away and dumps the heat outside, while fresh coolant entering the veins keep the cycle going. This method is more efficient than fans the same way swapping a handheld fan for an ice-cold bath is better. In a cold-plate system, the liquid-to-air heat transfer ratio ranges from 50% to 80%, sometimes more. The second technique, immersion cooling, is like dunking a hot frying pan into a pool of heat-hungry oil instead of blowing air on it. The oil, which is good at dissipating heat within itself, soaks up 100% of the pan's heat and keeps it from overheating. In the one-phase cooling method, like swirling cold water around the pan, the oil stays liquid but carries heat away. In two-phase cooling, the technique works the way water cools in a mud pot: the coolant fluid bubbles into vapour at a low temperature, rises into a cooling coil, condenses, drips back down, and repeats. 'These techs cut corrosion, boost reliability, and slash carbon footprint — all while running silent without fans,' the researchers wrote. Pioneers like Microsoft and Alibaba are already deploying these systems at scale. Green or just less dirty? To truly lower the carbon footprint of cooling technologies, scientists, policymakers, and lawmakers need to weigh its full impact. While the new solutions are innovative, they face hurdles. Coolant fluids involve different regulations, and complex designs delay deployment. Using them is like swapping plastic straws for paper: they are greener, but not without trade-offs. The world could end up trading one ecological problem for a different, even worse, one. If the electricity for an electric car comes from a coal power plant, the car's carbon footprint is still high. Similarly, cooling gains can backfire if pollution is merely shifted elsewhere. The study team's cradle-to-grave life cycle assessment evaluated air-cooled, cold-plate, and immersion cooling across emissions, energy, and water use, proving that sustainability demands systemic thinking, not isolated fixes. Twin engines of a green data centre The assessment revealed that with grid electricity, cold plates and immersion cooling cut greenhouse gas emissions by more than 15%, energy use by more than 15%, and water consumption by more than 31% — making them superior to conventional cooling technologies in use today. With 100% renewable energy, the team found the cuts could jump to 13% for emissions, 15% for energy, and 50% for water. 'Switching to renewables slashes emissions by 85-90%, energy use by 6-7%, and water demand by 55–85%, regardless of cooling tech,' the researchers wrote. Thus, life cycle assessments can reveal sustainability trade-offs either within the same cooling technology or when comparing different technologies. Ultimately, the calculus is clear: ICT's climate future hinges on tackling how the industry cools its data centres. T.V.
