  1. Water Bottles

  2. How many water bottles have you used this week?

  3. The problem with PET bottles Made from a non-renewable resource Do not biodegrade Do not recycle on a closed-loop system

  4. How PET plastic is made In the process of making the bottle, two chemicals are zipped together to form a polymer chain. DMT Ethylene Glycol

  5. This zipping produces a polymer to form the PET molecule

  6. Lifecycle of a PET water bottle

  7. Recycling can make this.. But we still use PET bottles so we are still using petroleum

  8. What if the Lifecycle of a PET water bottle looked like this…

  9. In 1996 the DuPont Company won a presidential Green Chemistry Award for Petretec -or the unzipping of the polymers in PET

  10. Petretec chemical reaction http://academic.scranton.edu/faculty/CANNM1/industrialchemistry/industrialchemistrymodule.html This means that we can now make old PET bottles back into new PET bottles.

  11. Has the problem been solved? • Made from a non-renewable resource The non-renewable resource is now renewable…sort of! • Do not biodegrade The new material still does not biodegrade • Do not recycle on a closed-loop system Petretec is a closed-loop recycling system but is only used for a fraction of the beverage bottles used in the world.
