3. Municipal Solid Waste (MSW) Landfilled waste : 53.8% (2012, EPA)

4. Gasification Energy conversion process a process that converts organic or fossil based carbonaceous materials High temperature achieved by reacting the material at high temperatures with a controlled amount of oxygen and/or steam Syngas hydrogen, carbon monoxide and methane Hydrogen Membrane Separator Fischer- Tropsch Reactor Gas turbine or IC engine Gas turbine or IC engine Generator Syngas (H 2, CO, CH 4 ) Syngas (H 2, CO, CH 4 ) Biodiesel Electricity pure Hydrogen Mechanical work

5. Why Steam? No N 2 dilution Steam works as source of H 2 H element is limited in feedstock Expected Higher H 2 concentration Increase syngas heating value Can be separated and recirculated Condensed water can be reused No CO2 data due to GC problem, for rubber
