Waste to Energy Pros and Cons

Cons

Pros

  • Public isnt convinced that WTE facilities are completely clean and free of harmful chemicals
  • WTE facilities are expensive to construct (so are landfills)
  • Majority of waist that goes in landfills can be re-used
  • Reduces weight and volume of waste before it enters a landfill
  • Capacity of landfills are expanded
  • Energy (heat and electricity) are produced from steam created during combustion process

Cons

Pros

  • Air pollution from combustion process
  • Possibility of toxic ash
  • (Although many pollutants can be removed before they enter the air)
  • Reducing the need for fossil fuels may prove to be more important in the future
  • Fuel is obtanable cheaply
  • There will always be a reliable source of fuel as people will always have waste
  • Energy can reduce the need to burn aditional fossil fuels creating electricity or heat

Cons

Pros

  • Removal of fly ash and acid gases from the stack result in bottom ash
  • Toxic ash may inadvertently be placed in regular MSW landfills creating the potential for toxic leachate in groundwater.

That Could Now Power That

  • Current landfill sites can be mined out and landfill material can be used as fuel
  • Separates natural resources to properly be recycled
  • Cheap energy
