Transcript

  • 1. RECYCLING Tyler Price
  • 2. FYI
    • Recycling - “ the act of processing used or abandoned materials for use in creating products.”
    • Part of the 3 R’s:
    • Recycling
    • Reusing
    • Reducing
  • 3. Why Recycling?
    • Protects environment
    • Protects us
    • Cleaner society/healthier
    • Helps economy
      • Saves money
      • Creates jobs
    • Protects our future
  • 4. Where does trash and waste go?
    • Landfills
    • Incinerators
    • Garbage Dumping (illegal in US)
      • Oceans/lakes
      • Empty fields
      • Someone’s backyard
    • Recycling plants
    • Composting
    • Water treatment facilities
    • Protective storage facilities
    “ Each individual generates about 1.5 tons of solid waste per year – about 4.5 pounds per person, per day. If we continue this pattern, we will have each created 90,000 pounds of trash in our lifetimes.”
  • 5. Trash Dumping:
    • Most countries do not have recycling programs or laws against trash dumping
    • Unhealthy, not sanitary, and it reeks
    • Poisons us and earth
    • Just plain wasteful
  • 6. Landfills: One Big HOLE
    • How? Trash is placed in a large hole dug away from populated areas
    • Barriers are put around the landfill to prevent leakage
    • Trash is compacted in the hole
    • Control systems monitor and maintain hazardous gas levels
    “ Every ton of recycled material saves 2.5 cubic yards of landfill space. The 868,000 tons of paper, glass, metals and plastic recycled in the Portland metro region in 2001 saved about 2.2 million cubic yards of landfill space.”
  • 7. Landfills Pt. 2: the bad, the ugly, and the dangerous
    • Hazardous materials can seep through landfills and into ground water even with barriers
    • High amounts of methane(flammable gas) are given off (accounts for 34% of all methane emissions)
      • Can seep into basements and cause explosions
      • Control systems were added after an explosion happened in Wisconsin
    • Does not bring business to the area
    “ The EPA (Environmental Protection Agency) has concluded that all landfills will eventually leak into the environment.”
  • 8. If it don’t work, burn it.
    • Pros
    • Easy way to reduce amount of trash
    • Can be used to generate steam to produce electricity
      • Saves money
    • Ash can be sorted for use as fertilizer
    • Cons
    • Hazardous pollutants can be released from smoke
    • Certain types of ash can be harmful
    INCINERATORS
  • 9.
    • Water Treatment Facilities
    • Recycles water from cities
      • By separating, cleaning, and sanitizing
    • Important because our fresh water supply is dwindling
    • Other options?
      • Dump it in oceans or fresh water sources
      • Can seep into groundwater if dumped on land
    • Hazardous Waste Facilities
    • Located away from communities
    • Funded by federal government
    • Protects us from radiation and dangerous fumes
    • Keeps it out of water supply
  • 10. FAST WATER FACTS
    • “ Polluted water is estimated to affect the health of 1.2 billion people, and contributes to the death of 15 million children annually.”
    • “ The World Health Organization estimates that 5 gallons is the minimum amount of water needed to meet a person’s daily needs.”
    • “ The average North American consumes over 105 gallons of water a day compared to the average European’s consumption of almost 53 gallons. The average person living in sub-Saharan Africa consumes only 2.4 – 5.3 gallons per day.”
    • “ The EPA’s water quality inventory found that 45 percent of lakes, 39 percent of rivers and 51 percent of estuaries in the US were not clean enough to support recreational uses such as fishing and swimming.”
  • 11. Hazard ous Waste
    • Types
    • Corrosive
    • Ignitable
    • Reactive
    • Toxic
    • Lifetime of hazardous gases in atmosphere
    • Aerosols- days to weeks
    • Methane- 12 years
    • Nitrous oxide- 114 years
    • Carbon dioxide- 50-200 years
  • 12. Nuclear Waste
    • Where From?
    • Weapon plants
    • Nuclear power plants
    • Nuclear-powered ships
    • Uranium mining
    • Where To?
    • Here and other states
    • 5 total sites in SC
    • Danger?
    • Doses of radiation have been linked to cancer and birth defects
    • Intense exposure can cause:
      • Large # of cells to die
      • Internal bleeding
      • Failure of vital organs
      • Death
  • 13. NIMBY Syndrome:
    • “ Get rid of it, just not in my backyard”
    • People do not want to deal with trash and waste but care when a landfill or nuclear waste facility is is built near their homes.
  • 14.
    • Glass = 100% recyclable (sorted by color)
    • Symbols used to designate different types of recyclable plastics:
    Recyclable Made From Recyclables IMPORTANT FACTS
