How a good transportation system could enhance life in urban India?

Considerable literature establishes the positive link between infrastructure development and an increase in output, productivity, growth, and employment. Studies on similar lines attribute high growth in eastern and central Chinese cities to transport connectivity. The lack of proper connectivity also explains the high income disparity in multiple Chinese provinces. We have seen earlier in this book in the section on urban history how key historical urban centres, including in India, prospered due to transport connectivity. Venice, New York, London, Amsterdam, Mumbai, Chennai, Kolkata, Singapore, Beijing, and San Francisco were all on major trade routes. Inland cities fared well, as road and later rail networks developed. Now, air connectivity is considered essential for any city to grow at a robust pace and sustain that momentum. Even in rural India, one of the most successful schemes has been the Pradhan Mantri Gram Sadak Yojana – a village road-building scheme started by former Prime Minister Atal Bihari Vajpayee. The scheme has continued despite the changing fortunes of leading national and regional parties in every state. I have personally interviewed hundreds of people in villages impacted by it and asked them why they rated this scheme as the best. The simplicity of their answers holds boundless lessons for policymakers. They told me that this scheme connected their villages to nearby urban centres and thus provided them year-round connectivity to better livelihoods and healthcare services. They said they could manage the other challenges on their own, but connectivity to better wage and livelihood opportunities in urban areas had transformed their lives. Transport plays an instrumental role in creating agglomeration economies, one of the defining features of cities and the key reason behind the success of cities. When combined with the tools of planning and urban land, transport can yield exponential gains. In the simplest terms, it can reduce commuter trips and commuting time, make it easier to do business, enhance functionality of labour markets and increase access to all services including employment Thus, it reduces transaction costs and makes cities everything that we can imagine – growth engines, equitable, sustainable, liveable, and resilient. If cities can be considered as living beings, transport is the blood that keeps our cities running. If it takes too much effort, cities may feel fatigued. If it clots, cities go into shock. A good city-wide transportation system is critical to achieving the agglomeration economies that come with urbanisation. An efficient transport system reduces transaction costs at all levels and becomes a facilitator for the economic growth and liveability of a city. It is the lynchpin that connects people to people, people to markets, people to places and people to services. If the transport system of a city is choked and congested, it renders the city inefficient and less productive. This is evident in many of the emerging cities in developing economies including India where citizens are spending hours daily commuting on congested roads and inhaling toxic air due to increased vehicular emissions. Innovative thinking on urban transportation can unlock many benefits. Jaimie Lerner was the young mayor of Curitiba, in Brazil. He went at breakneck speed to convert some major areas such as the Rua Quinze de Novembro, one of the major streets of the city, into pedestrianised zones. He believed the area should not be deserted when shops downed their shutters and cars parked away. In manoeuvring to implement his plan, he outwitted the shopkeepers, who were initially against it. Next, he introduced new lanes for buses, which was against the global tide in favour of subways. He made a telling remark about urban works, “If you want creativity, cut one zero from the budget. If you want sustainability, cut two zeros!” As the bus movement succeeded, he found new areas to unlock the growth of bus transport – elevated platforms through which passengers could move into buses, longer buses, and prepayment for tickets. Now, 85 per cent of the city uses the Bus Rapid Transit or BRT system and more than 300 cities globally are experimenting with it. If not done right, the costs of mismanaged and overlooked urban transport could be huge and far-reaching. The heightened urbanisation levels and even higher acceleration in motorisation levels does not bode well for urban transport in Indian cities. From 1951 to 2011, India’s population grew at an annual rate of 3.8 per cent. In the same period, the number of registered motor vehicles went from about 0.3 million in 1951 to nearly 142 million in 2011 – a double-digit growth rate. As per the Centre for Science and Environment, private vehicle ownership increased by 700 times, from 0.3 million in 1951 to 210 million in 2015. Half of this was added over a period of 57 years from 1951 to 2008, the remaining was added over the next six years. Between 1981 and 2011, the total number of registered vehicles grew at an average rate of 11.5 per cent. This trend looks set to continue at the hands of a growing urban population with increasing purchasing power. If unchecked, this trend could cause urban transport to become a serious handicap for efficient urbanisation. It could lead to choked road networks and further deteriorating air quality with serious public health implications. The issue of urban transport becomes more complex because Indian cities have failed to address basic issues. Commute options and corresponding costs significantly vary for different citizens when they step out for work or leisure. An upper middle-income household prefers a different mode of transport compared to someone from the lower middle-income group, or a poor migrant. The preferred choice of conveyance is mostly an owned vehicle, with little predilection for public transport – unless one’s means do not leave much to choose. Thereafter, congestion and pollution remain constant adverse companions throughout the commute. Commute time and costs are not the only trade-offs. In our failure to integrate land-use planning and transportation we have exponentially lessened the quality of life in our cities. Given the convoluted and institutional fragmentation in city transport, if we attempt to reform urban transport, we fail to locate where the actual responsibility lies. Some major obstacles to unleashing the benefits of a robust and efficient transport system in Indian cities are the lack of substantial focus on demand side management, little focus on non-motorised transport, a declining share of public transport and the inability to raise finances Notably, BRT failed in Delhi. But that shouldn’t stop other cities from championing it. Each city is different. While the BRT project failed to take off in Delhi, it has done remarkably well in the cities of Ahmedabad, which spurred adoption in other cities across India – Rajkot, Indore, Surat, the twin cities of Pune and Pimpri Chinchwad, and the twin cities of Hubballi-Dharwad. Curitiba, at the same time as it was pushing BRT, was championing waste recycling and providing as much as 50 sq mt of green space per person. Not surprisingly, Lerner became a three-time mayor of the city. Similarly, in Delhi, the metro rail services succeeded when the Central leadership, the state leadership under Sheila Dikshit, and the managing director of Delhi Metro Rail Corporation, E Sreedharan, came together. The success of Delhi Metro is so immense that cities all over India are now undertaking metro rail projects, even where it doesn’t make financial sense

Dust haze over Delhi-NCR raises PM10 levels up to 10-­fold in 5 hours

Delhi-NCR woke up to a thick dust haze over the region on Tuesday, leading to drastically reduced visibility and an up to 10-fold increase in PM10 concentrations in the air within a span of five hours. Delhi-NCR pollution level The weather office said the haze was caused by gusty westerly winds that kicked up dust under hot and dry conditions. Officials said visibility fell sharply over the past 24 hours, from 4000m to a minimum of 800m at Safdarjung and 700m at Palam between 9.30am to 10.30am. TimesView On Tuesday, the dust seemed to invade every pore of the city. Employing sprinklers and anti-smog guns are welcome, but they are, at best, piecemeal measures. Far stronger initiatives are required to make a real impact. “Strong dust-raising winds blew over Delhi-NCR since 6am. Wind speeds had touched 46-48kmph late Monday night, which moderated to 15-16 kmph by Tuesday morning,” said Kuldeep Srivastava, scientist, IMD. Track the pollution level in your city The city’s air quality index fell sharply from 162 (moderate) on Monday to 254 (poor). By 7pm on Tuesday, the AQI had fallen further to 294. The warm westerly winds also raised the minimum temperature to 27.4 degrees Celsius on Tuesday, up nearly 8 degrees in four days from 19.3 degrees C last Friday — making nights characteristically warm for this time of the year. Central Pollution Control Board’s data shows that the air quality started deteriorating from 6am and the concentration of PM10 and PM2.5 reached its peak at 10 am. PM10 levels at 4am was 140 micrograms per cubic metre and it rose to 940.5 micrograms per cubic metre at 10am in Delhi. The national ambient air quality standard for PM10 concentration is 100 micrograms per cubic metre. At Jahangirpuri, the PM10 levels shot up from 379 micrograms per cubic metre at 9pm Monday to 3,826 micrograms per cubic metre on Tuesday at 9am. The dust concentration affected visibility. At Safdarjung, considered the city’s base station, visibility was recorded at 800 metres around 9.30am and increased slightly to 1,800m by 3.30pm and to 2,500m by 5.30pm. Kuldeep Srivastava, scientist and head, Regional Weather Forecasting Centre, India Meteorological Department said winds, which peaked to 48 kmph at 4 am, led to a rise in dust particles which remained suspended in the air. “The dust-raising winds were caused by intense heating, with temperatures mostly above 40 degrees Celsius over the region and dry soil due to very less rainfall activity in the region for the past five days. Strong gusty winds blew over the area since midnight,” he added. Winds are likely to remain strong on Wednesday. “The air quality is expected to show gradual improvement and it may remain in the ‘poor’ category on Thursday. The AQI may show further improvement on Friday,” said V K Soni, head, environment and research centre, IMD. The Commission for Air Quality Management in NCR & Adjoining Areas (CAQM) reviewed the air quality scenario of Delhi-NCR and noted this to be an “exceptional episodic event which has led to continual dispersion of dust in the ambient air over entire Delhi-NCR and is likely to improve in one or two days, with rain also expected on Thursday.” Experts said dust is one of the major sources of pollution during summer. Anumita Roychowdhury, executive director, research and advocacy, Centre for Science and Environment (CSE), said, “Dust laden winds and dust storms influence summer air quality substantially. Rising heat, dry weather, resuspension of crustal soil and the regional weather systems combine to contribute to this trend. It is challenging to control such a phenomenon. This requires massive greening efforts at local and regional scale, stabilisation of loose soil and strategies to combat desertification.” According to the weather department there are chances of very light rain to drizzle on Thursday due to a fresh western disturbance approaching the region. On Tuesday, the maximum temperature was recorded at 39.9 degree Celsius, a notch below normal against 41.3 degrees C a day earlier. At 41.6 degrees C, Najafgarh was the warmest spot in the city. Tuesday was also drier than Monday. The humidity on Monday oscillated between 27 and 50%, dropping to 30-48% on Tuesday. According to the weather department, the maximum and minimum temperatures on Wednesday are likely to hover around 41 and 27 degrees C.

Delhi air quality: Dust winds increase pollution levels, cut visibility

The India Meteorological Department (IMD) said that strong winds blasted over Delhi on Tuesday morning (May16), producing dust, impacting air quality, and lowering visibility to 1,000 metres. Meteorologists blame the dusty conditions on a combination of extreme temperatures in northwest India over the last five days, dry land owing to a lack of rain, and strong winds that have lasted since midnight. In the early hours, the wind was blowing at 30-35 kmph. It will rain during the day, allowing the dust to settle," according to Kuldeep Srivastava, head of the IMD's regional forecasting centre, who spoke to PTI. "Dust concentration has gone up multiple times. The PM10 concentration rose from 140 micrograms per cubic metre at 4 am to 775 micrograms per cubic metre at 8 am. It is mainly because of strong gusty winds prevailing over the area. Dust will settle down soon," said V K Soni, the head of the IMD's Environment Monitoring and Research Centre, who spoke to PTI. Maximum temperatures in Delhi have risen beyond 40 degrees Celsius in the last four days, exacerbating the scorching weather. According to the IMD, a partly overcast sky and light showers in the evening may give limited relief. The high temperature is expected to reach 44 degrees Celsius by Sunday. Crucial conference on source apportionment study held in Delhi The Delhi government said on Monday that a roundtable discussion was convened to review the findings of a real-time source apportionment research on air pollution and to devise a strategy to enhance air quality in the city and the National Capital Region. On Monday, representatives from the Commission for Air Quality Management, Central Pollution Control Board, SAFAR, United Nations Environment Programme, India Meteorological Department, World Bank, Centre for Science and Environment, The Energy and Resources Institute, and NCR states attended the "Save Environment Roundtable Conference" at the Delhi Secretariat. “We shared the data collected during the source apportionment study over the past six months with the participants, sought their suggestions and prepared a strategy to further reduce air pollution in Delhi-NCR,” Rai said. "The ultimate goal is to devise policies at local and regional levels to enhance the air quality in Delhi," he said. Real-time source apportionment (RTSA) studies assist in identifying variables responsible for an increase in air pollution at any location, such as cars, dust, biomass burning, and industrial emissions, so that appropriate preventative actions can be implemented. Rai stated that orders have been issued to establish mobile air quality monitoring vans in 13 Delhi air pollution hotspots to determine the contribution of various pollution sources in real time.

Vans to monitor bad air at 13 pollution hot spots in Delhi

Delhi’s environment minister, Gopal Rai, on Monday unveiled plans to station mobile vans across the city’s 13 pollution hotspots for a week to pinpoint individual pollution sources for targeted action. Rai announced the move after he held a round-table conference to evaluate a real-time source apportionment study initiated in January, which identified secondary inorganic aerosols and vehicle emissions as the primary pollutants in the Capital. We have issued orders to deploy mobile air quality monitoring stations at Delhi’s 13 pollution hotspots, which will provide real-time data for prompt response to pollution rises,” said Rai. Data from the government’s supersite at Sarvodaya Bal Vidyalaya, Rouse Avenue, revealed that secondary inorganic aerosols — particles formed in the air because of gases reacting with each other from combustion sources — is the primary source of pollution in the Capital, followed by vehicle emissions. “The real-time study has been instrumental in identifying pollution sources and trends, facilitating swift government response to pollution spikes. In addition, it has enabled more accurate monitoring of PM2.5, NO2, NOx, CO, SO2, ozone, secondary inorganic, and organic aerosols,” said Rai. Seasonal data presented during the conference showed that secondary inorganic aerosols accounted for 33% of Delhi’s total PM 2.5 pollution load from November to January, with biomass burning (24%) and vehicles (17%) following. The same sources remained significant in February and March, contributing 26%, 22%, and 15%, respectively. However, data indicates that these sources shift, with vehicles contributing more pollution during summer months at 23%, followed by secondary inorganic aerosols (18%), and soil, road dust, coal, and fly ash each contributing 15%. This data was collected by a site established in November 2022 by IIT Kanpur in collaboration with IIT Delhi and The Energy and Resources Institute (TERI), and officially inaugurated by chief minister Arvind Kejriwal in January. The conference, attended by officials from government departments such as the environment department, Delhi Pollution Control Committee (DPCC), the Municipal Corporation of Delhi, and air pollution experts from bodies like TERI, IIT Kanpur, Centre for Science and Environment (CSE), the United Nations Environment Programme and the World Bank , aimed to pool knowledge on using real-time data and enhancing its functionality. “The ultimate goal is to develop local and regional policies to improve Delhi’s air quality, with a second conference planned for next month to further these discussions,” said Rai. Anumita Roychowdhury, executive director of research and advocacy at CSE, noted that while source profiles vary between summer and winter, vehicle emissions are a consistent pollution source. “Vehicles are the second biggest pollutant in the winter months, and they become the lead source in the summer period when aerosol formation is reduced slightly. This shows that we need to prioritise cracking down on vehicular pollution and investigate the increased prominence of coal and fly ash in the summer months,” said Roychowdhury.

Farm stubble burning on rise in Punjab and Haryana, but winds ward off threat in Delhi

NEW DELHI: Stubble burning cases are going up in the neighbouring states as the rabi crop harvest season is underway in the northern plains. Punjab and Haryana have recorded nearly 12,400 and 3,000 wheat stubble burning cases, respectively, so far this year. It is, however, lower than last year because rain delayed harvesting, said experts. The impact of stubble burning on Delhi's air quality is negligible in summer because of the wind speed but experts said stringent action was needed to ensure that farmland fire instances don't increase during winter. TimesView The fresh stubble burning incidents means that much more needs to be done to bring out a behavioural change among the farmers. It also means that in the winter the capital's pollution level would be adversely affected again. The governments of these states and the NCR should try to hammer out a solution as early as possible. Satellite data, analysed by the Council on Energy, Environment and Water (CEEW), has shown that 12,388 farmland fires were seen in Punjab and 2,968 in Haryana between April 16 and May 14 this year. Track the pollution level in your city In the same period, 18,801 and 4,903 stubble burning cases were recorded in Punjab and Haryana in 2022. Punjab saw 9,382 and Haryana witnessed 4,546 farm fires during the same period in 2021. L S Kurinji, a programme associate with CEEW, said: "So far, Punjab and Haryana have recorded nearly 12,400 and 3,000 wheat stubble burning cases, respectively. The states reported lower counts this year compared to the corresponding period last year because of unseasonal rain in March and April and the subsequent delayed harvest." She added that such fires were more in Ferozepur, Moga, Sangrur, Gurdaspur, Amritsar and Bathinda in Punjab and Karnal, Fatehabad, Sirsa, Kaithal and Sind in Haryana. Kurinji said while Rabi farm fires pale in comparison to the magnitude of Kharif fires, it is a reminder to act fast for the bigger winter problem. "Within a few weeks, farmers will start growing paddy. As an immediate step, state authorities must prioritise actions that limit residue generation and increase the cropping window. This includes phasing out PUSA 44, promoting early mature varieties like PR 126, switching to direct-seed rice and meeting the crop diversification target by promoting alternative crops," Kurinji said. She added that the wheat residue is highly valued by livestock rearing communities for fodder and biofuel producers due to lower moisture content compared to paddy straw. Therefore, farmers must encash the wheat residue instead of opting for burning. Anumita Roychowdhury, the executive director, research and advocacy at the Centre for Science and Environment (CSE), said: "The impact of farm fires on Delhi's air quality is expected to be minimal in summer due to high winds and more open natural ventilation. But there seems to be some contribution as is evident from the ongoing real time source apportionment study of the Delhi government." She said: "This shows the combined impact of farm fires and other biomass burning."

Facing mountains of waste & threat of relocation, Agra’s petha industry in a sticky situation

Agra: No trip to Agra is complete without two quintessential experiences — a visit to the Taj Mahal and buying boxes of the city’s iconic sweet, the petha. A translucent confection made from ash gourd, or white pumpkin, petha is a popular delicacy across India and is also exported to other countries. Beyond its culinary allure, the petha industry in Agra is also a significant economic catalyst for the city. As per news reports, this thriving industry serves as a livelihood for thousands of individuals, generating hundreds of crores in revenue each year. According to Amit Goyal, managing director of a popular brand Panchhi Petha, today there are over 1,500 petha-making units in the city which produce an estimated 700-800 tonnes of petha per day. To address the waste issue, the city administration has been in talks with owners of petha businesses to relocate the industry to Kalindi Vihar. Speaking to ThePrint, Agra Divisional Commissioner Amit Gupta said that at the 59th meeting of the Taj Trapezium Zone (TZZ) authority held last week, the issue of relocation had come up, but the industry representatives refused. The TTZ is a defined area of 10,400 sq km around the Taj Mahal to protect the monument from pollution. According to a study released in December 2021 by the Centre for Science and Environment (CSE), ‘Petha Waste Management in Agra City’, the city’s petha industry generates around 17,800 kg of solid waste per day, which consists mostly of ash gourd peels, sugar syrup, and water used in the manufacturing process. The waste is often dumped in public spaces, which raises the risk of outbreak of diseases like cholera, malaria, dengue, and diarrhoea, the study adds. “Such unauthorised dumping of petha waste leads to a foul smell in the area and attracts disease-borne vectors that infect nearby residents,” K.K. Pandey, project manager at the Agra Municipal Corporation’s Swachh Bharat Mission unit told ThePrint. Gupta said the administration has taken several steps to address the problem of petha waste. In 2018, the local administration launched a campaign to educate petha producers about the importance of proper waste disposal and even provided financial assistance to help petha manufacturing units in the organised sector to purchase waste-disposal equipment, he said. However, since a large section of the industry falls under the unorganised sector, government benefits don’t extend to them. According to a report by the National Institute of Food Technology Entrepreneurship and Management (NIFTEM), there are over 10 times more petha units in the unorganised sector than in the organised sector. This is not even the first time that the issue has come up during a TTZ authority meeting. According to news reports, the relocation of the petha units in TTZ has been in the works for 10 years, but the proposal has fallen flat each time. The reasons cited include lack of potable water in the proposed locations, lack of a garbage-disposal system, and no proper transportation. “In its latest bid to move the petha industry, the Agra administration wants to shift all the units to Kalindi Vihar across the Yamuna. But the proposed area lacks even basic amenities…The water in Kalindi Vihar is hard and undrinkable, and saltwater alters the taste of petha,” said Goyal of Panchhi Petha. Sunil Kumar Singhal, a petha seller, however, said that the industry has been demanding a ‘Petha Nagri’ behind Sikandra Sabzi Mandi on the Agra-Delhi Highway for a long time. By relocating there, he said, the units will have easy access to all amenities such as transportation, water and power. “The administration should focus on this demand instead of moving the industry to a location where it could not survive,” he said. But since the Agra Development Authority (ADA), the nodal agency overseeing the relocation, has already allocated land for ‘Petha Nagri’ in Kalindi Vihar, their demand remains unfulfilled, he added.

Govt holds round-table meeting to improve Delhi’s air quality

The monitoring of pollutants such as PM2.5, NO2, NOx, CO, SO2, ozone, secondary inorganic and organic aerosols has become more streamlined and precise,” the minister said.

Delhi Govt, University of Chicago Trust Sign MoU to Develop Measures to Curb Vehicular Pollution

New Delhi: The Delhi government’s Transport Department and the University of Chicago Trust (UC Trust) on May 12 signed a Memorandum of Understanding (MoU) to facilitate “an evidence-based approach to reducing vehicular pollution in Delhi”. The partnership will also involve setting up a research unit to design innovative policy interventions, as per a press release by the Energy Policy Institute at the University of Chicago, India (EPIC-India, that partners with numerous stakeholders to work on areas including electricity and markets). Vehicular pollution and Delhi Vehicular emissions – which produce pollutants such as nitrogen oxides and particulate matter (PM, which can cause numerous health-related illnesses including respiratory issues) – are among the contributors to Delhi’s air pollution. On-road PM emissions consist of both exhaust and non-exhaust components (such as PM caused by wearing of tyres and brakes). Studies in both 2021 and 2022 by the Centre for Science and Environment found that among local sources, vehicles contributed to around half of Delhi’s particulate pollution in October-November (including Diwali week). The MoU signed between the Delhi government’s Transport Department and the University of Chicago Trust (UC Trust) on May 12 aims to use data to design and develop policy interventions and solutions to curb vehicular pollution in the national capital. Per the statement, EPIC India researchers will help the transport department to “leverage insights from advanced statistics, machine learning, artificial intelligence, data visualisation, use of satellite data, and econometrics, etc to improve the effectiveness of its existing programs, and design changes to improve them”. “Apart from driving research that is evidence-based for policy innovation, evaluation, and capacity building, the cooperation will also facilitate knowledge exchange and high-quality data analysis,” the release said. Working with the government Researchers will also work with government officials to “enable knowledge exchange through seminars, workshops, or training sessions and carry out policy evaluation”, the release said. “We are excited to work closely with the researchers from the Energy Policy Institute at the University of Chicago Trust in India (EPIC India) and incorporate the application of research and policy expertise with the foresight to generate new policy initiatives and solutions, alongside a rigorous evaluation of the transport department’s existing programs,” said Ashish Kundra, principal secretary at the government of Delhi. “Having worked with governments around the world, including several state governments in India, for nearly a decade to advance evidence-based policymaking, EPIC-India is thrilled to contribute to these vital efforts to combat vehicular pollution and improve Delhi’s air quality,” said Michael Greenstone, Milton Friedman Professor in Economics and Director of the Energy Policy Institute at the University of Chicago.

India May Generate 1.8 Million Tonnes Of Solar Waste By 2050: How To Deal With The Problem Strategically

The rapid growth of solar energy in India has brought about several environmental benefits. However, it has also brought new challenges, such as the management of solar waste. India is currently the world's third-largest solar market, and the country has set ambitious targets to achieve 175GW of renewable energy capacity by 2022 and a further 450GW by 2030. The growth of solar energy is a significant step forward in the country's efforts to reduce greenhouse gas emissions and mitigate the effects of climate change. What Is Solar Waste? Solar waste refers to the waste generated by solar panels, batteries, inverters, and other equipment at the end of their lifecycle. Solar panels typically last for around 25 to 30 years, and once they reach the end of their lifespan, they become unusable and need to be replaced. The waste generated by these panels contains hazardous materials such as lead, cadmium, and other toxic chemicals that can be harmful to human health and the environment if not disposed of properly. Solar waste management in India is still in its early stages, and there is no comprehensive policy framework to regulate the collection, transport, recycling, and disposal of solar waste. A recent report by the Centre for Science and Environment (CSE) estimates that India could generate around 1.8 million tonnes of solar e-waste by 2050, which could pose a significant threat to the environment and public health if not disposed of properly. Challenges Of Solar Waste Management One of the significant challenges of solar waste in India is the lack of a proper policy framework for managing it. The government has not yet developed any specific regulations for solar waste, and there is no clear guidance on how to deal with it. Another challenge is the lack of awareness and infrastructure for solar waste management. Most people in India do not have adequate knowledge about the hazardous materials contained in solar panels and how to dispose of them safely. There is also a shortage of recycling facilities and the technology required to recycle solar panels and other equipment. Solar panels have a limited lifespan, and their disposal can lead to environmental hazards. To address this, the government can mandate manufacturers to produce solar panels with longer lifespans, and incentivise the recycling of end-of-life panels. The lack of proper disposal systems for solar waste could lead to the dumping of hazardous waste in landfills, which could pollute the air, water, and soil in the surrounding areas. Furthermore, there is a financial burden associated with solar waste management. The cost of recycling solar panels is currently high in India. To address this, the government can provide subsidies and tax breaks to encourage recycling and incentivise the development of innovative recycling technologies that reduce costs. In addition to its environmental impact, solar waste can also have economic consequences. According to a report by the International Renewable Energy Agency (IRENA), the global value of the materials recovered from solar panels could reach up to $15 billion by 2050. However, this potential revenue stream could be lost if solar waste is not managed properly, leading to increased costs associated with the disposal of hazardous waste. How To Deal With Solar Waste? There is a need for greater awareness among stakeholders about the potential environmental impact of improper disposal of solar waste. This can be achieved through public awareness campaigns and training programs for those involved in the solar industry. The private sector can also play a vital role in addressing the challenge of solar waste by investing in research and development of new recycling technologies and developing new business models that prioritise sustainability. In a nutshell, addressing the challenges of solar waste in India will require a multi-pronged approach that includes raising awareness, improving recycling infrastructure, introducing regulations, incentivising innovation, and supporting the development of longer-lasting solar panels. By adopting a strategic approach, India can address the challenges of solar waste and ensure the sustainable growth of its solar industry.
