  1. Hazardous waste and reducing waste Chapters 12.2 and 12.3

  2. Hazardous Wastes– 12.3 • Contains at least one toxic compound • Catches fire easily • Reactive or explosive • Corrodes metal containers

  3. Hazardous Waste Regulation in the United States • Resource Conservation and Recovery Act (RCRA) • Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) – NJ leads the nation in Superfund Sites, mostly thanks to Governor Christie Whitman (who ended up in charge of the EPA under George W. Bush) • National Priority List • Polluter-pays principle

  4. Superfund Sites – NJ has 113 as of 2013. • California – 98 • Pennsylvania - 96

The Love Canal Story • Love Canal was a waterway built in the 1800s next to Niagara Falls, NY. • Hooker Chemical Company purchased the site and used it for a chemical dump 1942-53. • Site was sold to local gov’t for $1. A housing development and school were constructed on the site in the 70s. • Chemicals began seeping into basements. • Housewife and resident Lois Gibbs brought problems to national attention in 1977. • Some families moved right away, some cleanup done.

  11. Deep-well Disposal

  12. Hazardous Waste Landfill

  13. Surface Impoundments: Trade-offs

  14. Dealing with Solid Waste Problems Chapter 12.2

  15. How can we reduce our production of solid waste? • 3 options for dealing with solid waste problems (Aka – the 3 R’s): • Producing less waste (Reduce) • Changing the materials used in products (Reuse) • Recycle

  16. Producing less waste - Reduce • Less waste – fewer/smaller landfills – less pollution • How can we produce less waste? • Manufacturers can produce less waste by redesigning products to use less material

  17. Reuse • Reusable bags for groceries • Repurposing household items for other things

  18. Composting – (Reuse) • “recycling” yard material • Yard waste is biodegradable and therefore can decompose naturally in a compost pile • Bacteria break down the waste until it becomes compost – a dark crumbly material that is rich in nutrients

  19. Recycling • Saves energy, water and other resources • After recycled materials are collected they are taken to a recycling center where they are sorted, cleaned, sorted again and made into new products.
