  1. Municiple Solid Wastes MSW = Pollution or Resource? Pollution is the contamination of air, water, or soil with undesirable amounts of material or heat. “Ecosystems dispose of wastes and replenish nutrients by recycling all elements”

  2. Factors Contributing to Increasing Amounts of MSW

  3. Factors Contributing to Increasing Amounts of MSW • Increasing populations • Changing lifestyles • Disposable materials* • Excessive packaging* * = two largest contributors to waste volume

  4. Changing Lifestyles of More People

  5. MSW Components in the US

  6. The Fate of MSW in the US

  7. Old Landfills • Leachate generation • Groundwater Contamination • Methane production • Incomplete decomposition • Settling

  8. Siting: Public Reactions • LULU (locally unwanted landuse) • NIMBY (not in my backyard) • NIMTOO (not in my term of office)

  9. Trash to Treasure • Highest (more than 1 million tons) net importers of MSW • Illinois • Indiana • Ohio • Pennsylvania • Virginia

  10. Waste to Energy: WTE

  11. Waste to Energy: WTE • 80% MSW burned for electrical energy production • 12% recovered and recycled • 8% put into landfill • Methane capture for electrical energy production.

  12. Reduction and Recycling • 75% MSW recyclable if: • Mandatory • Easy to do • $ Benefits

  13. Paper Glass Plastic Metals Yard wastes Textiles Old tires Compost Refabrication Synthetic lumber Sand or gravel Insulation Strengthens recycled paper Highways Secondary Recycling Match

  14. Sustainable MSW Management • Waste reduction • Safe waste disposal • Recycling and reuse • Electrical power generation
