The project mainly focuses on a quantitative analysis of the environmental impacts associated with a product, through a Life Cycle Assessment (LCA), following the guidelines proposed by the international standards ISO 14040 and ISO 14044. The products under study are polystyrene cups for hot beverages suitable for food contact. Specifically, these cups can be smooth or ribbed, and either transparent, white, or brown. Since the virgin polystyrene used in the intermediate layer of the cups is not in direct contact with the food, it can be replaced by post-consumer recycled polystyrene. So, this thesis will include scenario analyses focusing mainly on the implementation of environmental enhancement strategies. These strategies will primarily involve the replacement of a portion of the virgin polystyrene with recycled polystyrene (RPS), together with other variations, including changes in energy supply. Finally, a comparison with other commonly used types of cups will be conducted to provide a broader perspective on available alternatives, ultimately aiming to determine challenges and future perspectives for this class of products.

Abstract
The project mainly focuses on a quantitative analysis of the environmental impacts associated with a product, through a Life Cycle Assessment (LCA), following the guidelines proposed by the international standards ISO 14040 and ISO 14044. The products under study are polystyrene cups for hot beverages suitable for food contact. Specifically, these cups can be smooth or ribbed, and either transparent, white, or brown. Since the virgin polystyrene used in the intermediate layer of the cups is not in direct contact with the food, it can be replaced by post-consumer recycled polystyrene. So, this thesis will include scenario analyses focusing mainly on the implementation of environmental enhancement strategies. These strategies will primarily involve the replacement of a portion of the virgin polystyrene with recycled polystyrene (RPS), together with other variations, including changes in energy supply. Finally, a comparison with other commonly used types of cups will be conducted to provide a broader perspective on available alternatives, ultimately aiming to determine challenges and future perspectives for this class of products.File | Dimensione | Formato | |
