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.
