Presentation Transcript

  1. Sustainable Management of “Wastes” Prof Thomas DiStefano Bucknell University February 2009

  2. Sustainable Management of Municipal Solid Waste

  3. LCRMS Landfill

  4. methane + CO2 Gas leakage Anthropogenic Carbon

  5. Cogeneration – Electricity and Steam CO2 Landfill gas electricity Steam

  6. LCRMS currents converts ¼ of its landfill gas to electricity and hot water (cogeneration)

  7. Size-reduced MSW (Dano drum, Rapid City, South Dakota, U.S.A.)

  8. Sized-Reduced MSW

  9. Anaerobic Digestion of Solid Waste in Europe

  10. Digester Feeding

  20. Digester Feeding

  21. MSW collection anaerobic digester IC-CHP heat and electricity digestate

  22. fugitive emissions (0.1) (14.9) raw (84) biogas (15) materials fossil fuel (56) biogenic emissions recycle (42) (14) digestate(69) to U.S. power demand emissions gas anthropogenic GHG gas storage MSW collection (140) rotating sieve anaerobic digester IC-CHP landfill w/ gas recovery heat and electricity on-siteuse

  23. Annual energy demand and GHG emissions

  24. The potential effect of anaerobic biodegradation of MSW throughout the U.S. is considerable 140 million tons MSW/yr 5.9 billion m3/yr methane 15 billion kWh/yr Carbon tax credits of $40 to $60/MT CO2e Electricity consumption of 6.2 million US citizens Save 130 million metric tons of eCO2

  25. Carbon taxes would result in landfill tipping fees similar to the EU methane + CO2 carbon tax of $15 to $50 / MT CO2e 50 years : AD saves 6 billion MT CO2e and 4 trillion kWh
