3. Achieving “Zero Waste” Plasma arc technology offers a unique opportunity to achieve the “zero waste” goal by providing the capability to eliminate the need for land disposal of many hazardous wastes and to recover energy from municipal solid wastes and other organic wastes while producing salable byproducts and eliminating requirements for landfilling of ash or other residual materials.

4. What is PLASMA? “Fourth State” of matter Ionized gas at high temperature capable of conducting electrical current Lightning is an example from nature

5. Non-transferred arc plasma torch In a plasma arc torch, the plasma gas serves as a resistive heating element to convert electricity into heat. Because it is a gas and cannot melt, temperatures in excess of 7000°C can be produced.

7. Characteristics of Plasma Arc Technology Plasma acts as a resistive heating element that cannot melt and fail Produces temperatures of 4,000°C to over 7,000°C Torch power levels from 100kW to 200 MW produce high energy densities (up to 100 MW/m3) Torch operates with most gases – not a combustion process Elimination of requirement for combustion air : Reduces gas volume requiring treatment Reduces potential for formation of complex organics (i.e., dioxins and furans)

8. Plasma arc technology is ideally suited for waste treatment Hazardous & toxic compounds broken down to elemental constituents by high temperatures Organic materials Pyrolyzed or volatilized May be converted to fuel gases Amenable to conventional off-gas treatment Residual materials (radionuclides, heavy metals, etc.) immobilized in a rock-like vitrified mass which is highly resistant to leaching

22. Plasma Waste Processing and Demonstration System

23. Plasma Processing for Energy and Materials Recovery Research on waste destruction noted that pyrolysis produced useful fuel gases and inert residuals from organic wastes including MSW. Relatively high plasma energy requirements (~600 kWh/ton) and capital cost of complex molten bath reactors limited economic feasibility of pyrolysis processes. Use of gasification technology has made plasma a more economically attractive alternative.

34. PLASMA PROCESSING OF MSW AT COAL-FIRED POWER PLANTS Concept • Collocate MSW plasma processing plants (in modules of 1,000 TPD) with existing operational coal-fired power plants. • The amount of coal supplied to a plant will be reduced, proportionate to the thermal output of the MSW plant. • The hot gaseous emissions from the plasma plant afterburner system will be fed directly into the coal plant combustion chamber to supplement the combusted coal gases. • The combined plasma and coal gaseous emissions would produce steam and power equal to the normal coal plant generating capacity. • MSW would replace large volumes of coal for power generation in a very efficient, cost-effective and environmentally cleaner operation.

35. PLASMA PROCESSING OF MSW AT COAL-FIRED POWER PLANTS Reduced Capital Costs of MSW Plant(1) • Use existing power plant facilities – Steam generation system – Off gas treatment system – Electrical generating system • Use existing transportation network • Build on power plant land, if feasible (1) Geoplasma, LLC estimated costs

36. PLASMA PROCESSING OF MSW AT COAL-FIRED POWER PLANTS Summary By 2020, if all MSW was processed by plasma at coal-fired power plants (1 million TPD), MSW could: • Supply about 5% of U.S. electricity needs • Replace about 140 million TPY of coal • Eliminate about 15 million TPY of coal ash going to landfills • Provide significantly cleaner coal plant air emissions • Support the goals of the Clear Skies Act
