  1. Waste Disposal

  2. Mobro 4000 On March 22, 1987, an unassuming barge called the Mobro 4000 began a 6,000 mile voyage, looking for a port that would take its cargo--nearly 3,200 tons of trash. With its escort, the tugboat Break of Day, the Mobro would sail along the coast of the Eastern and Southern United States, down into the Gulf of Mexico and through the Bahamas, before finally returning to New York, still bearing its load of garbage.

  10. Lack of sites for sanitary landfills Reduced contamination of the waste stream Reduction in the environmental impacts associated with mining and mineral extraction Reduction in environmental impacts associated with incineration Energy Conservation (4x more energy required to produce an aluminum can from virgin materials Why Promote Composting, Recycling and Integrated Waste Management?

  11. Hazardous Wastes

  12. Secure Landfill

  13. Incineration

  14. Cost Benefit Analysis • Determination of potential environmental and human health effects for each alternative • Political reality (NIMBY; willingness to comply) • Economic analysis (marginal cost diagram, again) • Internalization of External Costs

  15. Legislative Approaches • Resource Conservation and Recovery Act (1976/1986) • Comprehensive Environmental Response Compensation and Liability Act (Superfund, 1980) • National Priorities List • Support of Brownfields Development • Ocean Dumping Ban (1988) • Permitting of Municipal Disposal Sites • Mandated Recycling • Increased Disposal Fees
