The spotlight on waste at the global climate table has sharpened India’s own urban dilemma. At the 30th Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC), or COP30, hosted by Brazil in Belém in November 2025, waste was recognised not as a peripheral urban nuisance but as a central climate variable. For India, where cities are expanding irreversibly, this global framing underlines an urgent domestic choice: whether urbanisation will deepen environmental distress or become a pathway to sustainable growth through circularity.
Why COP30 Put Waste at the Centre of Climate Action
COP30 marked a shift in climate discourse by placing waste and methane emissions at the core of mitigation strategies. Brazil launched the global No Organic Waste (NOW) initiative, backed by sizeable financial commitments to cut methane — a potent greenhouse gas largely emitted from landfills. The conference underscored circularity as a route to inclusive growth, cleaner air and healthier populations, calling on cities worldwide to treat waste as a resource rather than a liability.
This approach resonated strongly with India’s own advocacy of lifestyle-based climate action through Mission LiFE (Lifestyle for Environment), articulated at COP26 in Glasgow in 2021. Mission LiFE rests on the principle of deliberate utilisation instead of mindless consumption — a philosophy that aligns squarely with the circular economy.
Urban India’s Waste Burden: Numbers That Alarm
India’s cities are at the frontline of this challenge. Rapid urban expansion has already strained civic infrastructure, and multiple studies suggest that Indian cities lag behind global benchmarks in ensuring clean and healthy living environments. Pollution — air, water and land — has become a defining concern, particularly in regions such as the National Capital Region.
Projections underline the gravity of the situation:
- Urban India is expected to generate about 165 million tonnes of waste annually by 2030, emitting over 41 million tonnes of greenhouse gases.
- By 2050, with the urban population touching nearly 814 million, waste generation could surge to 436 million tonnes a year.
Unchecked, this trajectory threatens public health, economic productivity and India’s climate commitments. Against this backdrop, the national target of Garbage Free Cities (GFC) by 2026 is less about urban aesthetics and more about ecological survival.
From Cleanliness to Circularity: India’s Policy Push
India’s sanitation and waste reforms over the past decade provide a foundation for this transition. The Swachh Bharat Mission, which successfully eliminated open defecation within a defined timeframe, has since expanded its urban mandate to making cities garbage-free. Under SBM Urban 2.0, around 1,100 cities and towns have been declared free of dumpsites, though not entirely free of waste.
True garbage-free status, however, depends on systemic change. A circular economy model — where waste is minimised, reused, recycled and converted into energy — offers that pathway. For India’s nearly 5,000 cities and towns, shifting from a linear “collect–dump” model to circular waste management is now an existential necessity.
Organic, Plastic and Construction Waste: Three Urban Fault Lines
More than half of India’s municipal solid waste is organic, offering immediate opportunities for circular solutions. Composting — from household pits to large biomethanation plants — and compressed biogas (CBG) facilities can convert wet waste into green fuel and electricity, directly reducing landfill methane emissions.
Dry waste presents a tougher challenge. Over a third of urban waste is dry, with plastic emerging as the most problematic component due to its persistence, health impacts and low recyclability. Effective segregation at source remains the critical bottleneck, as recycling depends on clean, sorted streams processed through material recovery facilities. Refuse-derived fuel for cement and industrial use shows promise but still lacks scale, market depth and entrepreneurial momentum.
Construction and demolition (C&D) waste is another growing urban spoiler. India generates roughly 12 million tonnes of C&D waste annually, much of it dumped illegally along roadsides and open spaces. While a significant portion can be recycled into valuable construction material, enforcement remains weak. The Construction and Demolition Waste Management Rules, 2016, and the forthcoming Environment (Construction and Demolition) Waste Management Rules, 2025 (effective April 1, 2026), aim to fix accountability by charging bulk generators and strengthening compliance — a test case for urban governance.
Wastewater and Urban Water Security
Circularity in cities extends beyond solid waste. Wastewater recycling and reuse are critical for urban water security, particularly as India’s freshwater availability struggles to meet rising demand. States, which hold constitutional responsibility for water and sanitation, play a decisive role here.
Urban missions such as the Atal Mission for Rejuvenation and Urban Transformation (AMRUT) and SBM emphasise complete used-water and faecal sludge management. Reusing treated wastewater in agriculture, horticulture and industry is increasingly the only viable route to sustaining urban growth.
Institutional and Behavioural Hurdles to Circular Cities
Despite policy intent, achieving circularity remains complex. Waste management involves multiple actors — households, municipalities, private processors and markets — and each link in the chain is fragile. Segregation at source is inconsistent, collection logistics are uneven, and processing capacity often lags behind waste generation.
Recycled products face quality perception issues and weak market linkages, undermining financial viability. Extended Producer Responsibility has yet to cover all dry waste streams effectively. In the case of C&D waste, poor tracking and weak integration with building regulations dilute accountability.
Municipal resource constraints, limited inter-departmental coordination, and inadequate incentive–penalty frameworks further slow progress. These gaps were candidly acknowledged at recent national-level deliberations on urban rejuvenation.
Regional Cooperation and the Citizen Question
India’s leadership in proposing the Cities Coalition for Circularity (C-3), endorsed by Asia-Pacific nations in Jaipur, reflects recognition that cities learn best from one another. Knowledge-sharing platforms can accelerate adoption of tested models and technologies.
Yet, the success of circularity ultimately hinges on citizen participation. In an increasingly consumerist society, the first two Rs — reduce and reuse — are the hardest to operationalise. Recycling, supported by technology, private enterprise and robust policy, may therefore emerge as the most practical pillar of India’s circular transition, turning urban waste from a liability into a national resource.
