During the DEMO, the group comprising Roberta Salomone, Giovanni Mondello, and Teresa Maria Gulotta will show the importance of assessing the environmental impacts of a product, in particular a plastic bottle, focusing on its whole life cycle, from raw materials extraction to the disposal and treatment. It will be highlighted that a proper disposal of plastic by the consumer, and its recycling or reuse, following the Circular Economy concept, may reduce the marine litter and its related impacts. Using a laptop and an expository/interactive panel, you will understand these themes in an easy and enjoyable way.
