Market Issues Affecting EfW

• Tax/Legislative incentives created the industry without them, key drivers were eliminated

• Disposal, energy costs declined– Large regional landfills– Transportation systems– Deregulation

• All impacts to Commons not monetized

• EfW image as smokestack industry

• NIMBY

JGW2787 9

Technical Issues Affecting EfW

• Dioxin/Combustion Efficiency

• Acid gases

• Mercury

• Overall emissions control efficiency

• Corrosion/Erosion

• Bulkies
