India's Solid Waste Problem, By The Numbers

We all know that waste, and the way we manage it, is a serious problem in India. That much is not news. What was new to me was seeing the known, declared scale of the problem laid out in one place — in the draft red herring prospectus (DRHP) that GNI Infrastructure Limited filed with SEBI on 16 July 2026. The company is a road contractor that has moved into biomining of legacy waste dumps, so its DRHP carries a fairly detailed account of the sector it now works in.

The headline number is straightforward enough. India generated roughly 1,70,338 tonnes of municipal solid waste (MSW) every day in FY2021-22, per the Central Pollution Control Board (CPCB). Of this, only about 30-35% is scientifically processed. The rest goes into the ground, one way or another. Like an ostrich, if we cannot see it, we tell ourselves it is not there. It very much is.

Generation, Collection, Treatment — The Gap Widens At Each Step

The CPCB's 2020-21 report gives a fuller picture of where waste actually ends up once it is generated. Total generation that year was estimated at 160,038.9 TPD. Collection efficiency was high, at 95.4%, meaning 1,52,749.5 TPD was actually picked up. But only half of what was collected — 79,956.3 TPD — went through any form of treatment. Put together, close to a third of all the waste India generates is never formally processed or safely disposed of.

Zoom out to the annual figures and the trend is the same, only larger. The Ministry of Environment, Forest and Climate Change (MoEFCC) puts India's MSW generation at 62 million tonnes a year, growing at roughly 4% annually. On current trends, this is expected to touch 165 million tonnes by 2030. India already ranks seventh in the world by total waste generation volume, despite a relatively low per capita figure — a function simply of how many of us there are.

Engineered Landfills Are The Exception, Not The Rule

The DRHP, drawing on its own data and Dun & Bradstreet research, states that India has developed 1,244 engineered landfill sites. Of these, 669 have actually been constructed, and only 645 are currently operational. An engineered landfill is one built with the base liners, leachate collection and gas venting systems needed to handle waste, including hazardous and biomedical waste, without poisoning the land around it.

Set against this, 2,452 open dumpsites remain active across the country. And these are only the ones on record. Anyone who has driven past a roadside dump, a market backlot or a stretch of railway track knows the real number of unregulated dump sites is far higher. These sites have no liners, no leachate collection, no gas venting — nothing standing between the waste and our own soil and groundwater. It is a slow, steady contamination, and it is not headed anywhere good.

Hazardous and biomedical waste

On the hazardous waste side, 635 authorised recyclers process about 3,60,665 metric tonnes of catalyst and metal waste every year. Biomedical waste is handled by 208 Common Bio-Medical Waste Treatment Facilities (CBWTFs), with a combined capacity of 1,153 TPD — though this figure is as of 2020, six years old at the time of writing. Both networks are concentrated in urban centres. What happens to this category of waste in rural India is not well documented.

The Problem Starts At Home

Much of this traces back to a single, basic step: segregation at source. The National Sample Survey Office (NSSO) estimates that only 43% of urban households segregate their waste into wet and dry streams, and just 28% of rural households do the same. Everything else arrives mixed, which is precisely what clogs up composting units, recycling lines and waste-to-energy plants further down the chain. A system built to handle segregated waste cannot process what arrives as one undifferentiated heap.

Waste-to-Energy: Thin Capacity, Heavily Concentrated

Waste-to-energy (WTE) is often positioned as the adjunct to waste management in India, and the numbers show just how early-stage this remains. The country has only 13 operational WTE plants, with a combined capacity of 127.072 MW, processing about 6,800 TPD of non-recyclable MSW. Of these 13 plants, three are in Delhi alone, accounting for roughly 5,100 TPD — close to 80% of all-India WTE throughput — and generating about 52 MW, or roughly 40% of all-India WTE power output.

Sit with that for a moment. Ten plants, spread across the rest of the country, are left to service some of the largest and fastest-growing urban populations in the world. For a country of India's size and its stated ambitions on urban waste management, the installed base is thin.
