  1. Chapter 29 Waste Management Botkin and Keller Environmental Science 5e

  2. Modern Trends • Industrial Ecology • The study of relationships among industrial systems and their links to natural systems Botkin and Keller Environmental Science 5e

  3. Integrated Waste Management • Includes: • Reduce, reuse, recycle • Composting • Landfill • Incineration Botkin and Keller Environmental Science 5e

  4. Materials Management • A visionary goal requiring more sustainable use of materials combined with resource conservation • Eliminate subsides for extraction of virgin materials • Establish “green building” incentives • Assess financial penalties • Provide financial incentives • Increase new jobs Botkin and Keller Environmental Science 5e

  5. Solid-Waste Management • Composition • On-Site Disposal • Composting • Incineration • Open Dumps • Sanitary Landfills Botkin and Keller Environmental Science 5e

  6. Botkin and Keller Environmental Science 5e

  7. Sanitary Landfills • Are designed to concentrate and contain refuse without creating a hazard to public health or safety • Considerations: • Leachate is produced • Site Selection: Environmental justice • Monitoring Pollution • Federal Legislation Botkin and Keller Environmental Science 5e

  11. Hazardous Waste • Waste that is classified as definitely or potentially hazardous to the health of people • Serious environmental problems • Uncontrolled disposal sites could cause serious health problems • Need to develop safe disposal methods Botkin and Keller Environmental Science 5e

  12. Hazardous Waste Legislation • Resource Conservation and Recovery Act • CERCLA • Environmental Audit • Secure Landfill • Land Application • Surface Impoundment • Deep-Well Disposal Botkin and Keller Environmental Science 5e

  13. Botkin and Keller Environmental Science 5e

  14. Alternatives to Hazardous Waste • Source reduction, Recycling and resources recovery, Treatment, Incineration • Advantages • Chemicals can be reused • Less toxic = less problems • Smaller volume of waste • Less stress of waste disposal sites Botkin and Keller Environmental Science 5e

  16. Botkin and Keller Environmental Science 5e

  17. Ocean Dumping • Types of Waste • Dredge spoils • Industrial wastes • Sewage sludge • Construction debris • Solid waste • The most seriously affected areas are near shore Botkin and Keller Environmental Science 5e

  18. Botkin and Keller Environmental Science 5e

  19. Pollution Prevention • Identifying ways to prevent the generation of waste, rather than finding ways to dispose of it • Correct purchasing amounts • Better control of materials • Substituting non-toxic chemicals • Improving engineering Botkin and Keller Environmental Science 5e
