In recent decades, sustainability has become a key principle for economic and social development, with particular attention to its environmental dimension. In this context, the Life Cycle Assessment (LCA) methodology represents an essential tool for objectively and comparably quantifying the environmental impacts of products and processes throughout their entire life cycle.

Negli ultimi decenni, la sostenibilità è diventata un principio cardine per lo sviluppo economico e sociale, con particolare attenzione alla dimensione ambientale. In questo contesto, la metodologia Life Cycle Assessment (LCA) rappresenta uno strumento essenziale per quantificare in modo oggettivo e comparabile gli impatti ambientali di prodotti e processi lungo l’intero ciclo di vita. L’obiettivo della tesi è verificare la possibilità di semplificare la modellazione LCA, individuando metodologie capaci di restituire risultati affidabili e rappresentativi pur riducendo la complessità e il tempo di raccolta dei dati. Lo studio è stato condotto in conformità con le norme UNI EN ISO 14040 e UNI EN ISO 14044, applicando la metodologia LCA a una valvola multipurpose prodotta da Dafram S.p.A., seguendo le Product Category Rules (PCR) specifiche per questa tipologia di prodotto. Sono stati sviluppati e analizzati cinque scenari di modellazione, differenziati per grado di dettaglio, qualità dei dati e criteri di allocazione, con l’obiettivo di individuare configurazioni più sostenibili e realistiche. I risultati mostrano che, per la maggior parte delle categorie d’impatto ambientale (come Climate Change, Acidification e ADP Fossils), gli scenari semplificati producono risultati molto simili a quelli più dettagliati, dimostrando che approcci ridotti possono comunque garantire una stima attendibile degli impatti ambientali. Lo studio fornisce dunque un contributo concreto verso l’ottimizzazione della modellazione LCA, offrendo strumenti utili per decisioni strategiche orientate alla sostenibilità industriale.

Abstract
In recent decades, sustainability has become a key principle for economic and social development, with particular attention to its environmental dimension. In this context, the Life Cycle Assessment (LCA) methodology represents an essential tool for objectively and comparably quantifying the environmental impacts of products and processes throughout their entire life cycle. The aim of this thesis is to investigate the possibility of simplifying LCA modeling, identifying methodologies capable of providing reliable and representative results while reducing data collection complexity and time requirements. The study was carried out in accordance with the UNI EN ISO 14040 and UNI EN ISO 14044 standards, applying the LCA methodology to a multipurpose valve produced by Dafram S.p.A., following the specific Product Category Rules (PCR) for this product category. Five different modeling scenarios were developed and analyzed, differing in the level of detail, data quality, and allocation criteria, with the goal of identifying the most sustainable and realistic configurations. The results show that, for most environmental impact categories (such as Climate Change, Acidification, and ADP Fossils), simplified scenarios yield results very similar to those obtained with more detailed models, demonstrating that streamlined approaches can still ensure a reliable estimation of environmental impacts. Therefore, this study provides a concrete contribution toward optimizing LCA modeling and offers practical insights to support strategic decision-making aimed at enhancing industrial sustainability.| File | Dimensione | Formato | |
