TL;DR India is clearing its legacy waste faster than before, but it is also generating more waste than ever. While 65% of old landfill waste has been remediated and the waste management gap has fallen from 79.8% to 17%, rising consumption means the total burden remains high. Progress is real but uneven across states and constantly under pressure from growing volumes.

Context

The word “legacy” usually implies something worth keeping. In waste management, it means the opposite: the accumulated consequence of decades of civic neglect. India’s legacy waste problem began in earnest in the 1970s, when plastics entered urban consumption patterns, and cities had no system to handle them. The waste went to whatever open land was available. Over time, that open land became a dumpsite. The dumpsite became a hill.

Inside these hills is a heterogeneous mix that makes simple disposal impossible: partially decomposed organic matter, shredded plastics, broken glass, scrap metal, textiles, construction rubble, and, in many cases, hazardous industrial waste that was never supposed to be there, contaminating groundwater irreversibly within a radius of the site. The sites also continuously emit methane, a greenhouse gas with 80 times the warming potential of CO₂ over 20 years.

In this article, we look at the data on legacy waste in India.

Who compiles this data?
The data on legacy waste is compiled by the Ministry of Housing and Urban Affairs, based on the reporting by the states and UT’s in the Swachhatam portal, and also from the Central Pollution Control Board Annual reports.

Key Insights

Per Capita Waste Generation highest since 2015-16

For all the attention on India’s towering landfills, the more revealing story lies in what each person discards, day after day. Over the past decade, per capita solid waste generation has not followed a neat, linear path; it has fluctuated, even dipped briefly, but the broader trajectory is unmistakable. From 118 grams per day in 2015–16, it rises unevenly before surging sharply to 155 grams per day by 2022–23.

This is, in one sense, a development story: people consuming more is generally evidence that they can afford to. But consumption without commensurate waste management infrastructure is not prosperity; it is a subsidy on convenience, paid for by the urban poor who live near landfills and the groundwater that lies beneath them.

From 41% to 17%: India’s Waste Treatment Gap is narrowing

If waste generation tells the story of consumption, these numbers reveal something more consequential: the state’s evolving capacity to respond. India generated roughly 1.71 lakh tonnes of solid waste per day in 2022-23, of which 96% was collected, 61% treated, and 22% landfilled.

In 2016-17, the waste management gap, i.e. the share of generated waste that was neither treated nor responsibly disposed, stood at a staggering 79.8%. By 2022-23, it had fallen to 17%. Yet the absolute volumes tell a more uncomfortable story: waste generation has grown from roughly 1.01 lakh tonnes per day in 2015-16 to 1.71 lakh tonnes in 2022-23, meaning that even a dramatically improved system is processing a dramatically larger pile. Treatment capacity has expanded impressively, from 20,288 tonnes per day to over 1.04 lakh tonnes, but landfilling, that most primitive and damaging disposal method, still absorbed 38,147 tonnes every single day last year.

India is, in other words, getting better at a problem that is simultaneously getting bigger, and the risk is that efficiency gains are quietly being lapped by volume growth, leaving the net burden on land and public health largely unchanged.

65% of waste remediated, yet, the problem is still large

India’s legacy waste, the accumulated refuse of decades of inadequate urban waste management, stands at 25.09 crore metric tonnes across 2,474 identified dumpsites. As of March 2026, 65% of this, or 16.28 crore MT, has been remediated. But the number of existing dumpsites has barely moved from 3,151 in 2019-20 to 2,474 in 2022-23, even as reclamation and capping activity has picked up, rising from 87 sites in 2019-20 to 377 in 2022-23.

The government’s Dumpsite Remediation Acceleration Programme (DRAP), launched in November 2025 and targeting 214 high-burden sites with a September 2026 deadline, has remediated 528 lakh MT of a targeted 1,262 lakh MT, roughly 42%, showing decent progress.

The state-wise picture, however, is deeply uneven. Maharashtra alone accounts for 512.88 lakh MT of legacy waste, more than a fifth of the national total and has remediated only 42% of it. Karnataka (182.7 lakh MT, 42% remediated) and Rajasthan (116.06 lakh MT, 37% remediated) present similarly large and underserved burdens. Jammu & Kashmir has remediated only 27% of its 28.32 lakh MT, and Nagaland a mere 10% of its 8.1 lakh MT. Against this, Gujarat has achieved complete remediation of its 220.49 lakh MT, a genuine outlier and Telangana (90%), Uttar Pradesh (87%), and Delhi (81%) have made substantial progress despite carrying large absolute burdens.

Why does it matter?

Legacy waste is not just an environmental issue; it shapes the future of urban India. It poses direct health risks, contaminating groundwater, emitting methane, and exposing nearby communities to toxic fires. It also locks up scarce urban land, turning potentially valuable space into hazardous zones. At a larger scale, it contributes to climate change, with methane emissions adding to warming.

The progress in reducing the waste management gap shows improving state capacity, but uneven performance across states highlights persistent governance gaps. And most critically, India risks recreating the problem: as waste generation rises, without better segregation and processing, today’s waste could become tomorrow’s legacy.
