Q. What are the challenges to solid waste management in India? Discuss the governmental policy framework on solid waste management. Discuss the success/failure cases of Delhi and Indore cities highlighting the salient feature of their solid waste management initiatives.

Model Answer: 

India generates ~1.6 lakh tonnes of municipal solid waste daily (CPCB), but only ~50% is scientifically treated, creating severe public health, urban governance, and ecological crises.

Challenges to Solid Waste Management in India

• Low Source Segregation: Minimal citizen compliance and inadequate multi-stream collection infrastructure at the generation level.
• Informal Sector Marginalization: Failure to formally integrate ~4 million informal waste-pickers into municipal collection systems.
• ULB Capacity Deficits: Severe fiscal stress and technical incapacity among Urban Local Bodies for automated processing.
• Legacy Waste Hazards: Massive unscientific open dumping causing leachate percolation and groundwater contamination (e.g., Deonar landfill).
• Inefficient WtE Infrastructure: High moisture and low calorific value of unsegregated waste cause Waste-to-Energy operational failures.

Governmental Policy Framework

• SWM Rules, 2016: Mandates 3-stream segregation (Wet, Dry, Hazardous) and institutionalizes bulk waste generator accountability.
• Swachh Bharat Mission-Urban 2.0: Focuses on 100% scientific processing, remediation of all legacy dumpsites, and “Garbage Free Cities”.
• Extended Producer Responsibility (EPR): Legally binds brand owners and producers to collect and recycle plastic packaging.
• GOBARdhan & SATAT Initiatives: Incentivizes conversion of organic municipal solid waste into commercial Bio-CNG.

Comparative Case Studies: Indore vs Delhi

Indore (Success Model)

• 6-Stream Segregation: 100% door-to-door segregated collection (wet, dry, sanitary, domestic hazardous, e-waste, plastic).
• Circular Revenue Generation: Asia’s largest Bio-CNG plant (Devguradia) fuels city buses from wet waste.
• Zero-Landfill City: Eliminated open garbage bins (kachra ghar) and fully remediated 100 acres of legacy dumpsites.

Delhi (Structural Bottlenecks)

• Legacy Dumpsite Crisis: Overburdened landfills (Ghazipur, Bhalswa) prone to continuous methane fires and toxic air pollution.
• Fragmented Governance: Overlapping jurisdictions among civic agencies (MCD, DDA, PWD) impede unified waste monitoring.
• Unsegregated Incineration: Heavy reliance on WtE incinerators burning unsegregated, low-calorie waste generates toxic emissions.

Transitioning from Delhi’s centralized disposal model to Indore’s decentralized, circular, and citizen-led source-segregation architecture is critical for achieving SBM-U 2.0’s zero-landfill target.
