Pros
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
Pros
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
Pros
Current landfill sites can be mined out and landfill material can be used as fuel
Separates natural resources to properly be recycled
Cheap energy
Cons
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.
Cons
Air pollution from combustion process
Possibility of toxic ash
(Although many pollutants can be removed before they enter the air)
Cons
Public isnt convinced that WTE facilities are completely clean and free of harmful chemicals
WTE facilities are expensive to construct (so are landfills)
