1. Green Chemistry and beverage bottles

2. The job of green chemist Problem solver

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

4. DMT Ethylene Glycol Lets start at the beginning In the process of making the bottle, two dimers are zipped together to form a polymer, like the chain you made at the beginning of the lesson

5. This zipping produces a polymer (or many monomers) to form the PET molecule

6. Lifecycle of a PET beverage 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 beverage 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 The DuPont Company at their plant in North Carolina uses this process to recover 100 million lbs of PET annually

11. Has the problem been solved? Made from a non-renewable resource The non-renewable resource is now renewable Do not biodegrade This would be solved if we could get everyone to a Petretec processing plant Do not recycle on a closed-loop system Petretec is a closed-loop recycling system
