  • I respectfully disagree with a couple of the ideas on Wow: Waste Management's Ways to "Think Green" especially as it has to do with recover waste energy but will research this further externally on Sunday to see how I feel about this.

Recycling Energy & Resources from Waste

  1. 1. Recycling, Climate Change & Green Energy: Your Waste Makes a Difference! Presenter: Jeremy Abramowitz
  2. 2. What are we talking about today? <ul><li>Garbage : when you throw something “away,” what happens to it? </li></ul><ul><li>Recycling : how can we use our waste as a resource instead of throwing it out? </li></ul><ul><li>Energy : Where does it come from, how do we use it? </li></ul><ul><li>Climate Change : Why what we do with our waste and where we get our energy matters </li></ul>
  3. 3. Key Terms: What do you know about these concepts? <ul><li>Renewable Energy </li></ul><ul><li>Greenhouse Gas </li></ul><ul><li>Recycling </li></ul><ul><li>Biodegradable Material </li></ul>
  4. 4. Garbage: Where does it go? <ul><li>Most garbage in the U.S. goes to landfills. </li></ul><ul><li>A landfill is a specially designed site that must hold lots of garbage without letting solid material, liquids, or odors seep into nearby air, water, and soil </li></ul><ul><li>What might be some ways to reuse a landfill once it is capped and closed? </li></ul>
  5. 5. Landfills Have Gas! <ul><li>As garbage slowly breaks down inside a landfill, a gas called methane is released. </li></ul>Below: An engine powered by landfill gas generates renewable energy <ul><li>Methane facts: </li></ul><ul><li>Strong greenhouse gas (20x CO2 strength) </li></ul><ul><li>Can be used for energy (same gas found in natural gas) </li></ul><ul><li>Unlike natural gas, landfill gas is renewable and not a fossil fuel </li></ul>
  6. 6. Greenhouse Gas Basics: Waste Sector
  7. 7. Other Sectors Impacted by Changes in Waste Management Practices

  31. 31. … where does most litter end up? The ocean!!! <ul><li>The Great Pacific Garbage Patch or Pacific Garbage Vortex is the world’s largest collection of waterborne plastic. </li></ul>Not-so-fun facts about ocean plastic: -The Pacific Garbage Patch is twice the size of Texas! -Plastic does NOT biodegrade and harms seabirds and ocean life when it accumulates in the water -There is 5x as much plastic in the patch as plankton (natural debris) by weight Above: Harvesting plastic from the ocean Below: The ocean currents that deposit plastic into the Pacific Garbage Patch
