Abstract

Environmental protection issues are at the forefront of the vast majority of the media and public opinion. The study in question revealed the life cycle of a product commonly used in the home, the bottle of fresh pasteurised milk. The materials used for the manufacturing of the bottles are PET (PolyEthylene Terephthalate), plastic derived from fossil resources, and PLA (PolyLactic Acid), bioplastic derived from sugar cane, therefore from renewable resources. The life cycle of the bottles was carried out by highlighting the extraction phase of raw materials, the production of polymer, bottle, other packaging and distribution of milk and lastly, final disposal, excluding the phase of use, not significant for the purposes of this study. The studies were focused on two disposal scenarios, the current scenario and the one that is likely to take place in 10 years. In the current disposal scenario, there is no clear reduction in environmental impact from the comparison of the materials examined. With reference to the 2030 disposal scenario, the PLA turns out to be much more environmentally friendly.
