<p>On July 3rd, two members of our team spoke with a (chemical engineer *get his full work title*) from Ampacet in Terre Haute about our project. As a plastics expert, Dr. Jared Tatum explained the processes that are done at Ampacet. While discussing our project, Dr. Tatum offered the team PET plastic samples for our experiments. He will be giving us pure PET bottles, PET pellets, and PET powder. After explaining our experimental protocol ideas, Dr. Tatum advised us to change our procedures. Our original idea had been to let the bacteria eat the pellets as their only carbon source and observe the change. However, Dr. Tatum advised that we use the powder instead of the pellets because of the greater surface area to volume ratio. Additionally, he informed the team about the effect that humidity plays on the characteristics of pure PET. He encouraged us to monitor the humidity during our experiments and note any change in results based on a difference in humidity. Because pure PET is so susceptible to changes based on humidity, PET used in disposable water bottles contain a great amount of additives to stabilize to the plastic and ensure long shelf life. Based on this new information, we designed an experiment that would determine the effects of these additives on the ability of the bacteria to breakdown the PET.</p> | <p>On July 3rd, two members of our team spoke with a (chemical engineer *get his full work title*) from Ampacet in Terre Haute about our project.
