  1. Dr. Jeffrey Morris Sound Resource Management Olympia, Washington, USA Tel. 360-867-1033 Jeff.Morris@zerowaste.com CRRA Conference - August 4, 2008 Measuring the Environmental Impacts of Organic Material Discards

  2. Life Cycle Analysis (LCA) Wastes & Pollution

  3. Climate Change Human Health – Particulates Acidification Eutrophication Human Health – Toxics Human Health – Carcinogens Ecosystems Toxicity Ozone Depletion Smog Habitat Disruption Biodiversity Depletion Ecosystem Services Degradation Resource Depletion Life Cycle Impact Categories

  4. ICLEI CACP (www.iclei-usa.org/action-center/tools/ cacp-software) WARM (www.epa.gov/climatechange/wycd/waste/ calculators/Warm_home.html ) MSW DST (Research Triangle Institute) EIO-LCA (www.eiolca.net) BEES (www.bfri.nist.gov/oae/software/bees/model.html) TRACI (www.epa.gov/nrmrl/std/sab/traci/) MEBCALC (Sound Resource Management) NRC calculator (www.nrc-recycle.org) NERC calculator (www.nerc.org) CEI (www.zerowaste.com) Available Models

  5. Composting: aerobic composting WTE Incineration: mass burn thermal conversion/ advanced thermal recycling (offset to natural gas powered electricity generation) Gasification/Pyrolysis: averages for advanced thermal conversion technologies (offset to nat. gas electricity) Landfill+Energy: 75% methane capture & conversion to electricity via an internal combustion engine (offset to natural gas electricity) Definitions of Terms on Graphs

  6. CO2 Emissions: Composting vs. Disposal(tons eCO2/ton)

  7. Particulate Emissions: Composting vs. Disposal(tons ePM2.5/ton)

  8. Acidifying Emissions: Composting vs. Disposal(tons eSO2/ton)

  9. Eutrophying Emissions: Composting vs. Disposal(tons eN/ton)

  10. Toxics Emissions: Composting vs. Disposal(tons eToluene/ton)

  11. Carcinogenic Emissions: Composting vs. Disposal(tons eBenzene/ton)

  12. EcoToxics Emissions: Composting vs. Disposal(tons e2,4-D/ton)

  13. Gasoline & Diesel: capturing 100% of household compostable materials equivalent to 30% cut in household vehicle fuel & oil use. Electricity: capturing 100% of household compostable materials equivalent to 5% cut in household electricity use. Meat & Dairy: capturing 100% of household compostable materials equivalent to 50% cut in household meat and dairy consumption. Climate Cooling Benefits of Composting (from WA CEI)

  14. Value of Pollution Reductions

  15. Value of Pollution Reductions from Recycling & Composting

  16. The End Thank you.
