Racing against time: India and South Asia grapple with rapidly rising waste volumes

 

South Asia is at a critical crossroads as it faces a massive surge in waste generation that is set to nearly double by 2050, according to the World Bank’s latest "What a Waste 3.0" report. The region, which currently produces 346 million tonnes of municipal solid waste annually, is projected to see a 99% growth in volume over the next quarter-century, fueled by rapid population growth and accelerating urbanization. 

Despite having the lowest per capita waste generation rate globally at 0.49 kilograms per day—nearly half the global average—the region’s massive population, particularly in India, makes it the third-largest waste-generating region in the world. India alone accounts for 74% of the regional population and generates approximately 58% of its municipal solid waste, a total that is projected to grow from 210 million tonnes in 2022 to over 376 million tonnes by 2050.

​The management of this mounting waste remains a significant challenge, with one-third of all waste generated in South Asia currently left uncollected and primarily managed through open burning. While urban areas show a median collection coverage of 88%, rural regions lag behind significantly at just 54%. Disposal practices are dominated by uncontrolled dumpsites, which receive 38% of the region’s waste and lack essential environmental controls, leading to frequent site failures and fatalities. 

Only 6% of waste is disposed of in controlled landfills, while materials recovery remains limited, with recycling and composting each accounting for just 11% of waste treatment. This shortfall in infrastructure has severe environmental consequences, as South Asia is identified as a major source of unmanaged plastic waste, producing 14 million tonnes annually that often leak into rivers and oceans.

​India has emerged as a regional leader in attempting to reform this landscape through the Swachh Bharat Mission, a large-scale national campaign launched in 2014 and expanded in 2021 to focus on full door-to-door collection and the remediation of legacy waste. Quoting Government of India data, the report claims, the mission has already achieved notable successes, with urban collection rates in India now reaching 95%, and high-performing cities like Ahmedabad, Indore, and Surat reporting rates as high as 98%. 

India is also pioneering the world’s largest dumpsite mining effort to reclaim land from over 2,200 sites containing 461 million tonnes of legacy waste, believes the report. Furthermore,  the country is considered unique in its efforts to formally integrate informal waste workers—who play a vital but often unrecognized role across South Asia—through cooperatives like Pune’s SWaCH, which provides door-to-door services.

​As the region moves toward 2050, the financial and climate stakes of inaction are becoming increasingly clear. The report emphasizes that establishing basic waste management systems—including collection, transport, and disposal—carries a significant price tag, estimated at between 40 and 45 United States Dollars (USD) per tonne in lower-income countries. 

This baseline cost can escalate to over 120 USD per tonne for more advanced systems that incorporate recycling and landfill diversion. Inadequate waste management is also a key factor in urban flooding, as uncollected debris blocks drainage systems, a risk that is intensifying due to climate change. 

While these basic systems in lower-income settings require steady investment, the region currently struggles with limited funding and user fees that are insufficient to recover service costs. To avert escalating economic losses and public health risks, the World Bank emphasizes that redirecting a modest share of GDP into sustainable systems is essential to lock in service reliability and support a transition toward a circular economy.
