India's Growing Waste Crisis: International Research Solutions
All Indian cities are approaching a breaking point. Burning agricultural waste, coupled with poor waste management, is contaminating urban air and water nationwide. A substantial international research project based at University of Leeds has begun to identify solutions. Its findings are important to students, policymakers, and the public in India.
Two studies published in May of 2026 and peer-reviewed collected international and Indian researchers from the University of Leeds, IIT Kharagpur, King's College London, the London School of Hygiene and Tropical Medicine, CSIR-NEERI, Manipal Institute of Technology, Albokoes EnviroSustain Pvt Ltd, and Hong Kong Baptist University. They represent what are arguably the most pressing challenges in the Indian environment: Municipal Solid Waste and Crop Residue Burning. The results of both studies illustrate that India's current trajectory can still be altered, but urgent action is required.
These findings serve students of engineering, environmental science, public health, and public policy in India, for they provide the most current and credible research available concerning some of India's most pressing sustainability challenges.
Garbage Mountains by 2050 and What the Study Found
The first study, published in the Journal of Industrial Ecology, provides an alarming projection. It has been estimated that if current consumption patterns continue, the total Municipal solid waste (MSW) produced by urban India will increase by a factor of 12 by the year 2050. This is a grave projection that should be of concern in any class or policy setting.
As Daya Pandey, an Assistant Professor in Energy Systems at the University of Leeds in the School of Mechanical Engineering, says, “If we carry on with business as usual, mountains of garbage will surround India's major cities.”
The research team has examined nearly two decades of historical waste and projected several scenarios for the period up to 2050. The team’s main argument is that India lacks modern infrastructure for waste management, and investment in this area is sorely needed. Some specific options include improved waste segregation at the source, greater expansion of recycling and processing operations, and a substantial reduction in current reliance on landfills.
The goals of the waste research team, as mentioned above, are more than just environmentally motivated; they also have legal value. The Indian Solid Waste Management Rules, 2026, promote source segregation, and reduction in land use, research, and modernisation of waste circular infrastructure are in direct alignment, making this a valuable read for students of environmental law and urban planning.
Agricultural Burning and the Path to Renewable Energy
The second study, published in Biomass and Bioenergy and co-authored by scholars at Leeds and at IIT Kharagpur, tackles a problem no less important. Given the widespread prevalence of in-situ crop residue burning (the practice of burning leftover stubble in fields after harvest), agriculture ranks as the second-largest contributor to greenhouse gas emissions in India.
The study provides evidence that the considerable amount of agricultural waste produced in India need not be a burden. Through a combination of innovation, strategic policy changes, and a circular bio-economy, this waste can be transformed into renewable energy and high-value materials. The authors of this research believe that effective management of agricultural waste would help meet emissions reduction targets and the goal of improving rural energy, employment, and income by addressing an issue that is rarely addressed concurrently.
IIT Kharagpur assistant professor and co-author Dr Vinay Yadav described the intensity of the issue, "India's cities are heading toward a waste management disaster. This is not just about the accumulation and disposal of litter across the multiple communities that make up our metropolitan areas, but about the urgency to act on the health of our citizens, the climate, and the liveability of our cities. The good news is that this disaster can be avoided. With intelligent legislation and additional infrastructure coupled with the principles and practice of a circular economy, we can address the waste problem in our cities and turn the crisis into a setting where waste is minimised, and a resource is recycled to create value."
Importance of UK-India Academic Cooperation for Students
Both studies highlight the significance of international academic collaboration. This encompasses more than one aspect of environmental science; it reveals the results of collaboration among researchers from different countries and the consequences for the future generation of Indian researchers and students.
Dr Daya Pandey elaborated on the Indian-UK collaboration, “UK universities bring knowledge in public health, climate policy and net-zero analysis, whilst Indian partners offer a greater understanding of governance, financing and human behaviour. There is no single answer to address this concern, but countries like India, which are in the fast-growing phase, require waste management systems that can be locally customised and policy-led.”
Mohit Arora, Engineering lecturer at King’s College London, also one of the authors of the study, noted that the sustainability and the decarbonization of the developing world is a collective obligation where the universities play the key role.”
The University of Leeds and IIT Kharagpur have a joint collaboration in research and teaching, and a partnership agreement in 2024 for joint PhD supervision within the disciplines of Engineering, Transport Studies, and Biological Sciences. In June 2025, a delegation, headed by the Vice Chancellor and President of Leeds, Professor Shearer West, visited New Delhi to establish collaborative research and teaching partnerships in medicine, engineering, biotechnology, and the social sciences.
