The core of a good answer
India’s solid waste problem lies in poor segregation, weak processing capacity, legacy dumpsites and stressed municipal finances; the framework of the SWM Rules (2016, replaced by the 2026 Rules) and Swachh Bharat Mission addresses these, and Indore’s source segregation and waste-to-wealth model succeeded where Delhi’s reliance on landfills produced garbage mountains that are only now being cleared.

What the question asks
Three parts: challenges, the policy framework (rules and missions), and a contrast of Delhi and Indore with their salient features. The case part needs specific features and outcomes for both cities, not a general statement.
Answer outline
Introduction
Urban India generates large volumes of mixed waste daily. The Solid Waste Management Rules, 2026, which replaced the 2016 Rules from 1 April 2026, together with Swachh Bharat Mission (Urban) 2.0 aim at garbage-free cities.
Challenges
- Low segregation at source, so wet and dry waste mix and cannot be processed efficiently.
- Processing gaps: composting, biomethanation and recycling capacity lags generation; much waste goes to open dumps.
- Legacy dumpsites cause fires, methane, leachate and health hazards.
- Weak municipal finances, low user fees and informal waste pickers outside the formal system.
- Low citizen participation and weak enforcement against bulk generators.
Policy framework
- SWM Rules 2016 under the Environment (Protection) Act, 1986, superseded by the SWM Rules 2026 (announced by MoEFCC on 28 January 2026, in force 1 April 2026).
- 2026 Rules: four-stream segregation (wet, dry, sanitary, special care); bulk waste generators (20,000 sq m area, 40,000 litres water a day or 100 kg waste a day) must process wet waste on site or obtain an EBWGR certificate.
- Landfill only for non-recyclable, non-energy-recoverable and inert waste; higher fees for unsegregated waste; annual landfill audits.
- Time-bound biomining of all legacy dumpsites, CPCB online portal, environmental compensation on the polluter-pays principle, RDF use in cement and WtE plants rising from 5% to 15% over six years.
- Swachh Bharat Mission Urban 2.0 for garbage-free cities; Swachh Survekshan ranking; related rules on plastic, e-waste and construction and demolition waste.
Indore: success
- Ranked cleanest city alone for six consecutive years and jointly with Surat in Swachh Survekshan 2023; placed in the Super Swachh League in 2024-25.
- Salient features: source segregation, door-to-door collection and strong citizen participation.
- Waste to wealth: Gobar-Dhan bio-CNG plant (inaugurated 19 February 2022) treats 550 tonnes a day of wet waste, producing about 17,000 kg bio-CNG and 100 tonnes compost a day on a zero-landfill model; PPP with Rs 150 crore private investment; CNG used for city buses.
Delhi: failure turning to remediation
- Reliance on three legacy landfills (Ghazipur, Bhalswa, Okhla); Ghazipur opened in 1984, reached capacity in 2002 and still received waste; major fire in April 2024.
- Weak segregation and processing allowed waste mountains to grow, with fire, air and groundwater pollution.
- Remediation: CPCB direction on biomining (27 January 2021), CAQM Direction No. 91 (3 June 2025); according to the Delhi Chief Minister (October 2026), about 217 lakh tonnes were cleared from the three sites in about 18 months, freeing nearly 100 acres.
Lessons
- Segregation and decentralised processing matter more than disposal capacity.
- Citizen ownership, political continuity and viable PPP models drive results; landfills should be the last option.
Conclusion
Indore shows that cleanliness is a governance and behaviour outcome, not a matter of city size; Delhi shows the cost of neglecting segregation. The 2026 Rules now give every city the tools, and enforcement will decide the result.
Examples and data to cite
- MoEFCC, SWM Rules 2026 announced 28 January 2026, effective 1 April 2026 (PIB).
- PIB, 19 February 2022: PM inaugurated Indore’s 550 TPD Gobar-Dhan bio-CNG plant.
- PIB, 11 January 2024: Indore and Surat joint cleanest cities in Swachh Survekshan 2023; Indore had been sole winner six times in a row.
- PIB, 17 July 2025: Indore, Surat and Navi Mumbai entered the Super Swachh League in Swachh Survekshan 2024-25.
- Rajya Sabha reply, 23 July 2026: seven legacy dumpsites in Delhi-NCR identified for remediation, three of them in Delhi; four completed in NCR.
Facts to remember
- Bulk waste generators produce about 30% of total solid waste (PIB on 2026 Rules).
- Landfill performance under the 2026 Rules is to be overseen by District Collectors.
- A state committee chaired by the Chief Secretary recommends measures to the CPCB.
- Local bodies may levy fees on waste generators under their bye-laws and are encouraged to generate carbon credits.
