- India is expanding waste-to-energy (WtE) plants to convert non-recyclable waste into power under the Solid Waste Management Rules, 2026.
About Waste-to-Energy (WtE) Technology
- Energy Conversion: Converts non-recyclable municipal and industrial waste into usable electricity or heat through controlled processes like incineration, gasification and anaerobic digestion.
- Core Methods: Includes incineration, gasification, and anaerobic digestion for energy recovery.
- Current Status: India has 21 operational WtE plants and 133 biogas facilities.
Key Benefits of Waste-to-Energy Technology
- Landfill Burden Reduction: WtE plants reduce municipal solid waste volume by nearly 90%, helping cities manage over 62 million tonnes of annual waste generation in India.
- Methane Emission Control: Diverting organic waste from landfills prevents methane release, a greenhouse gas 28 times stronger than CO₂, significantly lowering climate impact.
- Renewable Power Generation: India’s operational 21 WtE plants produce over 170 MW of electricity, contributing to decentralised urban energy supply.
- Alignment with SDGs: Supports SDG-7 (Clean Energy) and SDG-11 (Sustainable Cities) by integrating urban waste management with renewable energy systems.
Government Initiatives for Harnessing Waste-to-Energy in India
- National Bio-Energy Mission: Promotes large-scale production of biogas, bio-CNG and power generation from agricultural residue and organic urban waste.
- National Biofuel Policy (2022): Encourages biofuel generation from waste streams to meet the 20% ethanol blending target by 2025, reducing fossil fuel dependence.
- Solid Waste Management Rules (2016): Mandate source segregation, waste treatment, and the promotion of refuse-derived fuel (RDF) for energy recovery.
- Draft Waste-to-Energy Policy (2023): Seeks to establish a comprehensive regulatory and investment framework for expanding WtE infrastructure nationwide.
Key Concerns of Waste-to-Energy Technology
- Toxic Air Pollution: Incineration releases pollutants such as dioxins, furans, and heavy metals, which are linked to increased respiratory illnesses in nearby populations.
- High Capital Intensity: Each WtE facility costs roughly ₹5–10 crore per MW, making projects financially challenging for urban local bodies.
- Recycling Disincentive: Heavy reliance on WtE has reduced recycling rates by 10–15% in some countries compared with recycling-first systems.
- Poor Waste Quality: Low segregation levels in India, with only around 40% segregated at source, reduce fuel efficiency and plant output.
- Administrative Hurdles: Lengthy approvals delay projects; E.g., the Bandhwari WtE plant in Gurugram faced multi-year clearances and local protests, slowing rollout.
Way Forward
- Universal Segregation: Enforce strict wet-dry separation with penalties and incentives under Solid Waste Management Rules; E.g., Indore’s city-wide 100% segregation system.
- Technology Upgradation: Invest in advanced methods like gasification and anaerobic digestion for higher energy recovery; E.g., modern biogas plants under the GOBARdhan scheme.
- Public-Private Partnerships: Leverage private capital and expertise for plant construction and operation; E.g., PPP-based WtE facilities in Pune and Hyderabad.
- Source Segregation: Enforce household-level wet-dry waste separation to improve feedstock quality; E.g., Japan’s Zero Waste community-driven segregation system.
“Waste is not a problem but a misplaced resource.” With segregation-first systems, clean technologies and regulation, Waste-to-Energy can advance India’s circular economy and net-zero transition.
