With India generating over 170,000 tonnes of municipal solid waste daily while importing nearly 85% of its crude oil requirement, Waste-to-Energy (WtE) offers an opportunity to address both waste management and energy security through a circular economy approach.
- Environmental Sustainability
- Reduces landfill burden and legacy waste, lowering methane emissions.
- Prevents open burning of waste, improving urban air quality.
- Minimises groundwater contamination caused by landfill leachate.
- Reduces marine pollution by diverting plastic waste from rivers and coasts.
- Resource Efficiency
- Promotes the Waste-to-Wealth and Circular Economy by recovering energy.
- Encourages segregation and recycling, conserving virgin raw materials.
- Produces organic manure and digestate from biomethanation, reducing fertiliser dependence.
- Facilitates urban mining through recovery of recyclable materials before energy extraction.
- Energy Security
- Generates electricity through incineration plants.
- Produces Compressed Biogas (CBG) under the SATAT Initiative and GOBARdhan Scheme, reducing dependence on imported LPG and natural gas.
- Diversifies India's renewable energy mix through decentralised energy generation.
- Strengthens rural energy access and local energy resilience.
Therefore, an integrated Waste-to-Energy strategy, supported by source segregation, EPR and strengthened Urban Local Bodies, can simultaneously advance environmental sustainability and energy security.
