Waste to Landfill

  • landfilled waste suitable as a fuel
    • plastics
    • paper and cardboard
    • wood
    • textiles
  • calorific value of ‘fuel’ in waste ~ 63 PJ/year
    • could genrate13GJ / year of electricity
    • assuming 20% efficiency
  • Australia’s electricity consumption in 2014-15
    • 700 TJ
    • 13 GJ = 2% of annual demand
    • Hazelwood supplies 5.4% of national demand

Current Emission Reduction Fund Methods

  • Do not cover energy from burning waste
  • ERF Methods available for Waste include
    • Destruction of Landfill gas
    • Source Separated Organic Waste
    • Waste Water Treatment
    • Alternative Waste Treatment
      • Composting organic waste (avoiding anaerobic generation of methane)
      • Anaerobic digestion where biogas is captured for heat or electricity generation
      • Organic matter processed into a solid fuel alternative
