The main purpose of this thesis is to present, through various methods, the environmental impact of a Bluetooth speaker following different life cycle strategies. In a context of growing awareness of the electronic waste issue (WEEE) and the recognition of virtuous models, including the Circular Economy, designers are called upon to change course in their projects, particularly concerning electronic devices. An in-depth research phase enabled the analysis of the speaker’s disassembly process and the classification of its components, with the aim of identifying those that are critical in terms of disassembly and recyclability. An LCA analysis was conducted comparing three case studies: a speaker based on the linear economy model and two speakers characterised by a circular approach (one fixed through a repair center and one fully repaired by the user due to the speaker's modularity). In addition, the materials used, manufacturing processes, energy consumption and disposal were taken into account for the analysis. The results suggest that redesigning a speaker to make damaged components easier to repair can significantly improve the product’s durability and sustainability.
Lo scopo principale di questa tesi è presentare, attraverso diversi metodi, l’impatto ambientale di uno speaker bluetooth seguendo differenti strategie di ciclo di vita. In un contesto di crescente consapevolezza riguardo al problema dei rifiuti elettronici (RAEE) e al riconoscimento di modelli virtuosi, tra cui l’Economia Circolare, il progettista è chiamato a cambiare rotta nella progettazione, in particolare per quanto riguarda i dispositivi elettronici. L’approfondita fase di ricerca ha permesso di analizzare lo smontaggio e la catalogazione dei diversi componenti dello speaker preso in esame, con il fine di identificare quelli critici in termini di disassemblaggio e riciclabilità. Successivamente è stata condotta un’analisi LCA confrontando tre casi studio: uno speaker basato sul modello di economia lineare e due speaker caratterizzati da un approccio circolare (uno riparabile tramite centro di riparazioni e uno completamente aggiustabile da parte dell’utente grazie alla facilità di disassemblaggio). Inoltre, sono stati presi in considerazione i materiali utilizzati, i processi produttivi, il consumo energetico e lo smaltimento. I risultati suggeriscono che una riprogettazione orientata al facile disassemblaggio dei componenti danneggiati di uno speaker può migliorare significativamente la durata e la sostenibilità del prodotto.

Abstract
The main purpose of this thesis is to present, through various methods, the environmental impact of a Bluetooth speaker following different life cycle strategies. In a context of growing awareness of the electronic waste issue (WEEE) and the recognition of virtuous models, including the Circular Economy, designers are called upon to change course in their projects, particularly concerning electronic devices. An in-depth research phase enabled the analysis of the speaker’s disassembly process and the classification of its components, with the aim of identifying those that are critical in terms of disassembly and recyclability. An LCA analysis was conducted comparing three case studies: a speaker based on the linear economy model and two speakers characterised by a circular approach (one fixed through a repair center and one fully repaired by the user due to the speaker's modularity). In addition, the materials used, manufacturing processes, energy consumption and disposal were taken into account for the analysis. The results suggest that redesigning a speaker to make damaged components easier to repair can significantly improve the product’s durability and sustainability.| File | Dimensione | Formato | |
