4 They also estimate that transporting the resin and converting it into bottles requires an additional 20,000 MJ of energy per ton of PET. 3 When put together, the energy to produce and transport the PET resin, and then mold it into bottles, totals approximately 100,000 MJ per ton of PET. Conclusion and Summary: Energy Required for 2006 U.S. Bottled Water Consumption Because bottled water required approximately 1 million tons of PET in 2006, those bottles required roughly 100 billion MJ of energy. A barrel of oil contains around 6,000 MJ, so producing those bottles required the equivalent of around 17 million barrels of oil. This is enough energy to fuel one million American cars for one year.

Flow diagram showing examples of where energy is required during bottled water manufacturing, use, and disposal. Energy is required at each major stage, as well as with transportation between stages. This fact sheet only analyzes the first two orange boxes, which together require the equivalent of 17 million barrels of oil. 3 Typical caps weigh around 2 grams and are not usually made of PET. 4 I.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
