Potential GHG offset
� GHG Emissions from Coal � 2-3 tons CO2 per ton of coal combusted
� For every ton of MSW processed in a plasma plant, up to 2 tons of CO2 is reduced from the atmosphere.* � Reduced methane emissions from not landfilling the wastes � Reduced CO2 from reduced coal combustion-to-electricity
Advantages
¨ Gasification Technology Performing at Atmospheric Pressure, Elevated Temperature and High Plant Availability
¨ Capable of Utilizing Integrated Mixed Waste and/or Coal Fines/Waste as Feed
¨ Compact and Modular
