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
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
Current landfill sites can be mined out and landfill material can be used as fuel
Separates natural resources to properly be recycled
Cheap energy
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.
Air pollution from combustion process

(Although many pollutants can be removed before they enter the air)
