  1. Chapter 23Solid and Hazardous Waste

  2. Question of the day List the top five materials that you think get thrown away into landfills. At your house, what would be your top five materials thrown away.

  3. Overview of Chapter 23 • Solid Waste • Types of Solid Waste • Waste Prevention • Reducing the Amount of Waste • Reusing Products • Recycling Materials • Hazardous Waste • Types of Hazardous Waste • Management of Hazardous Waste • Environmental Justice

  4. Solid Waste • US generates more solid waste per capita than any other country • 1.98 kg per person per day • Types of Solid Waste • Municipal solid waste • Solid material discarded by homes, office buildings, retail stores, schools, hospitals, prisons, etc • Relatively small portion of solid waste produced • Non-municipal solid waste • Solid waste generated by industry, agriculture, and mining

  5. Zero waste family http://nomoredirtylooks.com/tag/zero-waste-family/

  6. Composition of Municipal Solid Waste

  7. Disposal of Solid Waste • Three methods • Sanitary Landfills • Incineration • Recycling

  8. Sanitary Landfill • Compacting and burying waste under a shallow layer of soil • Most common method of disposal

  9. Chester County Solid Waste Authority http://www.chestercountyswa.org/

  10. Sanitary Landfill • Problems • Methane gas production by microorganisms • Contamination of surface water & ground water by leachate • Not a long-term remedy • Few new facilities being opened • Closing a full landfill is very expensive

  11. Sanitary Landfill • Special Problem of Plastic • Much of plastic is from packaging • Chemically stable and do not readily break down and decompose • Special Problem of Tires • Cannot be melted and reused for tires • Made from materials that cannot be recycled • Can be incinerated or shredded

  12. Tires • http://tire-conversion.com/index.php/why-we-recycle/general-information • Household Hazardous Waste Days • Chester County, PA http://www.chestercountyswa.org/pdf/LHSchedule.pdf • Delaware County, PA http://www.co.delaware.pa.us/recycle/hhw.html

  13. The Plastic problem Pacific Ocean Garbage Issue DVD-Clip from Wired Science

  14. Question of the day: Why is plastic debris a problem in our oceans? What is the name of the “garbage patch” in the Pacific Ocean? How could you help reduce this plastic burden?

  15. Incineration • Volume of solid waste reduced by 90% • Produces heat that can make steam to generate electricity • Produce less carbon emissions than fossil fuel power plants (right)

  16. Incineration • Types of Incinerators • Mass burn (below) • Modular • Refuse-derived

  17. Incinerator • Problems Associated with Incineration • Yields air pollution • Produce large amounts of ash • Site selection often controversial

  18. Chester, PA “Trash to Steam” Plant http://www.delcotimes.com/articles/2009/07/06/news/doc4a51b600e9972546641127.txt?viewmode=fullstory http://www.covantaenergy.com/en/list-of-facilities/videos.aspx

  19. Composting • Includes: • Food scraps • Sewage sludge • Agricultural manure • Yard waste • Reduces yard waste in landfills • Can be sold or distributed to community

  20. Dive! http://www.youtube.com/watch?v=0HlFP-PMW6E Interesting concept

  21. How to yard compost? http://www.youtube.com/watch?v=ZqWTYB_XLwE&feature=related

  22. Waste Prevention • Three Goals • (1) Reduce the amount of waste • (2) Reuse products • (3) Recycle materials

  23. Reducing Waste • Purchase products with less packaging

  24. Reducing Waste • Source reduction • Products are designed and manufactured in ways that decrease the volume of solid waste in the waste stream • Pollution Prevention Act (1990) • Dematerialization • Progressive decrease in the size and weight of a product as a result of technological improvements

  25. Reusing Products • Refilling glass beverage bottles • Heavier glass that costs more • Japan recycles almost all bottles • Reused 20 times

  26. Recycling Materials • Every ton of recycled paper saves: • 17 trees • 7000 gallons of water • 4100 kwatt-hrs of energy • 3 cubic yards of landfill space • Recycle • Glass bottles, newspapers, steel cans, plastic bottles, cardboard, office paper

  27. Recycling • Recycling Paper • US recycles 50% • Many developed countries are higher • Recycling Glass • US recycles 25% • Costs less than new glass • Can be used to make glassphalt (right)

  28. Recycling • Recycling Aluminum • Making new can from recycled one costs far less than making a brand new one

  29. Recycling • Recycling Metals other than Aluminum • Lead, gold, iron, steel, silver and zinc • Metallic composition is often unknown • Makes recycling difficult • Recycling Plastic • Less than 20% is recycled • Less expensive to make from raw materials

  30. Recycling • Recycling Tires • Few products are made from old tires • Playground equipment • Trashcans • Garden hose • Carpet • Roofing materials • 36% of tires are currently recycled to make other products

  31. Upcycle- Monday’s Project-. Create! Creativity! Terracycle Freecycle http://www.urbanfarmonline.com/urban-farm-magazine-and-books/urban-farm-exclusives/upcycle.aspx?cm_mmc=Vanity-_-upcycle-_-na-_-van

  32. Recycling research continued Finish posters from previous week and share out

  33. Single Stream recycling http://www.youtube.com/watch?v=J_RWqgXcP_k

  34. Cell phone recycling • http://www.youtube.com/watch?v=sCU4o_Ce9PM&NR=1&feature=fvwp • The AfterLife of Cell Phones • http://www.nytimes.com/2008/01/13/magazine/13Cellphone-t.html?pagewanted=all&_r=0 • Terracycle- video and website

  35. Integrated Waste Management

  36. Question of the day: 1. What qualifies as hazardous waste? 2. Why do you think it needs separate disposal? What is Superfund? (just guess)

  37. Hazardous Waste • Any discarded chemical that threatens human health or the environment • Reactive, corrosive, explosive or toxic chemicals • Types of Hazardous Waste • Dioxins • PCBs • Radioactive waste

  38. Management of Hazardous Waste • Chemical accidents • National Response Center notified • Typically involves oil, gasoline or other petroleum spill • Current Management Policies • Resource Conservation and Recovery Act (1976, 1984) • Comprehensive Environmental Response, Compensation, and Liability Act (1980)

  39. Resource Conservation and Recovery Act (1976, 1984) • The Resource Conservation and Recovery Act (RCRA)gives EPA the authority to control hazardous waste from the "cradle-to-grave." This includes the generation, transportation, treatment, storage, and disposal of hazardous waste. RCRA also set forth a framework for the management of non-hazardous solid wastes. The 1986 amendments to RCRA enabled EPA to address environmental problems that could result from underground tanks storing petroleum and other hazardous substances. • HSWA - the Federal Hazardous and Solid Waste Amendments - are the 1984 amendments to RCRA that focused on waste minimization and phasing out land disposal of hazardous waste as well as corrective action for releases. Some of the other mandates of this law include increased enforcement authority for EPA, more stringent hazardous waste management standards, and a comprehensive underground storage tank program.

  40. Management of Hazardous Waste • Cleaning up existing hazardous waste: superfund program • 400,000 waste sites • Leaking chemical storage tanks and drums (right) • Pesticides dumps • Piles of mining wastes • Must be cleaned up

  41. Love Canal • First site of it’s kind. Sparked CERCLA. (aka Superfund) http://www.youtube.com/watch?v=vKIM9sE0t6I&safety_mode=true&persist_safety_mode=1&safe=active http://upload.wikimedia.org/wikipedia/commons/2/2c/Hooker_Electrochemical_Quit_Claim_Deed_to_Board_of_Education.pdf

  42. Case-In-Point Hanford Nuclear Reservation

  43. Management of Hazardous Waste • Superfund National Priorities List • 2006: 1558 sites on the list • States with the greatest number of sites • New Jersey (115) • California (93) • Pennsylvania (93) • New York (86) • Michigan (65)

  44. Superfund: What is it? Superfund is the name given to the environmental program established to address abandoned hazardous waste sites. It is also the name of the fund established by the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (CERCLA statute, CERCLA overview). This law was enacted in the wake of the discovery of toxic waste dumps such as Love Canal and Times Beach in the 1970s. It allows the EPA to clean up such sites and to compel responsible parties to perform cleanups or reimburse the government for EPA-lead cleanups.

  45. Management of Hazardous Waste • Biological Treatment of Hazardous Chemicals • Bioremediation • Phytoremediation • Management the Waste we are Producing Now • (1) source reduction • (2) conversion to less hazardous materials • (3) long-term storage

  46. Management of Hazardous Waste • Hazardous Waste Landfill

  47. Activity In small groups, you are going to research an assigned recycling topic. Write down some facts and information on easel paper. Present to class your topic. Read selected article. Summarize article in one paragraph. Be able to teach someone else about your article. Include some facts and figures.

  48. Environmental Justice • Environmental Justice and Ethical Issues • Right of every citizen, regardless of age, race, gender, social class, to adequate protection from environmental hazards • Fundamental human right • Grassroots campaign • Mandating environmental Justice- Federal Level-Clinton 1994, 1997 case in LA, nuke facility(Ur processing plant)

  49. Environmental Justice • International Waste Management • Developed countries sometimes send their waste to developing countries • Less expensive than following laws within the country • Controversial aspect of waste management • Basel Convention (1989) • Restricts international transport of hazardous waste

  50. Question of the day: From when you woke up till APES class, make a list of all the things you have thrown away? Do you think about the packaging of a product before you buy it? (How about those Starbucks/Wawa cups?) How often do you reuse objects, recycle objects?
