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

¨  Non-Polluting and Environmentally Safe ¨  High Recovery of Clean Renewable Energy as Electricity ¨  Economically Competitive ¨  Proven Technology
