Presentation Transcript


Reuse

  • Drink containers

  • Ziploc bags

  • Tupperware

  • Plastic grocery bags


Reduce

  • Packaging

  • Diapers

  • Grocery Bags

  • Lunch bags

  • Make products last longer

  • Precycling – do I really need this?


Recycle

  • Primary

    • Closed loop

    • Creates products of the same type

  • Secondary

    • Open loop

    • Converted into new

      products

Compost

  • Rich in organic matter and soil nutrients

  • Microorganisms break down waste


MRFs materials recovery facility

  • Separates trash from materials that can be recycled

  • Recycles or burns remaining combustible waste

  • Problems:

    • Expensive

    • Energy to separate trash

    • Must have large input of garbage

    • Toxic pollutants

Source separation

  • Separate trash from recyclables at home or business

  • Advantages:

    • Little pollution

    • Moderate operating costs and more jobs

    • Less energy

  • Problems:

    • Rely on people to correctly separate

    • Hard to compete with MRFs


Plastics


Versatility

  • Flexible or rigid; transparent or opaque.

  • Look like leather, wood, or silk.

  • Made into toys or heart valves.

  • The basic raw materials for plastic are petroleum and/or natural gas.

    • These fossil fuels are sometimes combined with other elements, such as oxygen or chlorine, to make different types of plastic.


What to do with my soda bottle?

  • Throw it in the trash (Landfill)

  • Recycle it and reuse it!

  • Incinerate it for energy


1 PET  Polyethylene Terephthalate

  • Two-liter beverage bottles, mouthwash bottles, boil-in-bag pouches.


2 HDPE  High Density Polyethylene

  • Milk jugs, trash bags, detergent bottles.


3 PVC Polyvinyl Chloride

  • Cooking oil bottles, packaging around meat

  • Burning PVC plastic, which contains 57% chlorine when pure, forms dioxins, a highly toxic group of chemicals that build up in the food chain.


4 LDPE  Low Density Polyethylene

  • Grocery bags, produce bags, food wrap, bread bags


5 PP  Polypropylene

  • Yogurt containers, shampoo bottles, straws, margarine tubs, diapers.


6 PS  Polystyrene 

  • Hot beverage cups, take-home boxes, egg cartons, meat trays, cd cases.


7 Other

  • All other types of plastics or packaging made from more than one type of plastic.


Not Economical

  • In recent years, several plastics recycling companies have closed their doors.

  • They claimed they could not sell their products at a price that would allow them to stay in business.

  • Thanks to the relatively low cost of petroleum, the price of virgin plastic is so inexpensive that recycled plastic cannot compete.

  • The price of virgin resin is about 40 percent lower than that of recycled resin.


Paper or Plastic?

20-40% less E to manufacture plastic

1 truckload of plastic = 7 truckloads of paper


Plastic Energy!

  • Stored energy - made from fossil fuels.

  • Contain as much energy as petroleum or natural gas

    • much more energy than other types of garbage.

  • an ideal fuel for waste-to-energy plants.


  • Because recycled plastic is more expensive, people aren’t exactly lining up to buy it. Surveys conducted by Procter & Gamble and others show that while most people expect their plastic to be recycled, they won’t go out of their way or pay a few cents more to buy a bottle made of recycled plastic. Recyclers say plastics recycling won’t be profitable until we close the loop by creating more demand for recycled plastics.
