This thesis investigates how architecture can engage with the principles of circularity by reconsidering the temporality of materials and the afterlife of buildings. Through the case studies of Expo 2015 in Milan and Expo 2025 in Osaka, as well as a practical collaboration with Asanuma Corporation in Japan, it explores how temporary structures and construction waste can be transformed into new architectural resources. The first part analyzes the material systems and reuse strategies of fifty-seven national pavilions across both Expos. It distinguishes between symbolic and operative sustainability, revealing that while many pavilions proclaim intentions of reuse, only a few demonstrate tangible second-life scenarios. This comparison highlights the persistence of gaps between design ambitions and their practical realization, as well as the need for clearer regulatory and logistical frameworks supporting reuse. The second part translates these insights into practice through an experimental project on recycled gypsum. Conducted within the renovation of the Asanuma Corporation office, it examines how dismantled gypsum boards can be crushed, remixed with natural binders, and reformed into removable acoustic and decorative panels. The results expose both the technical potential and the contradictions of circular design: while hybrid mixtures enhance performance and texture, they also complicate future recyclability. By linking global exhibition architecture with local material experimentation, Matter and Time argues that circularity is not merely a technical solution but a cultural approach. It frames reuse as a design language that redefines waste, value, and the temporal dimension of architectural practice.
Questa tesi indaga come l’architettura possa confrontarsi con i principi della circolarità, ripensando la temporalità dei materiali e la “seconda vita” degli edifici. Attraverso i casi studio di Expo 2015 a Milano ed Expo 2025 a Osaka, così come una collaborazione pratica con Asanuma Corporation in Giappone, il lavoro esplora come le strutture temporanee e i rifiuti da costruzione possano essere trasformati in nuove risorse architettoniche. La prima parte analizza i sistemi materici e le strategie di riuso di cinquantasette padiglioni nazionali dei due Expo. Distingue tra sostenibilità simbolica e operativa, rivelando che, mentre molti padiglioni dichiarano intenzioni di riutilizzo, solo pochi dimostrano scenari concreti di seconda vita. Il confronto mette in luce la persistenza di divari tra le ambizioni progettuali e la loro effettiva realizzazione, oltre alla necessità di quadri normativi e logistici più chiari a supporto del riuso. La seconda parte traduce queste osservazioni nella pratica attraverso un progetto sperimentale sul gesso riciclato. Condotto nell’ambito della ristrutturazione degli uffici di Asanuma Corporation, esamina come le lastre di cartongesso smontate possano essere frantumate, miscelate con leganti naturali e riformate in pannelli acustici e decorativi removibili. I risultati mettono in evidenza sia il potenziale tecnico sia le contraddizioni del design circolare: se da un lato le miscele ibride migliorano prestazioni e texture, dall’altro ne complicano la futura riciclabilità. Collegando l’architettura espositiva globale alla sperimentazione materica locale, Matter and Time sostiene che la circolarità non sia semplicemente una soluzione tecnica, ma un approccio culturale. Inquadra il riuso come un linguaggio progettuale che ridefinisce rifiuto, valore e dimensione temporale della pratica architettonica.

Abstract
This thesis investigates how architecture can engage with the principles of circularity by reconsidering the temporality of materials and the afterlife of buildings. Through the case studies of Expo 2015 in Milan and Expo 2025 in Osaka, as well as a practical collaboration with Asanuma Corporation in Japan, it explores how temporary structures and construction waste can be transformed into new architectural resources. The first part analyzes the material systems and reuse strategies of fifty-seven national pavilions across both Expos. It distinguishes between symbolic and operative sustainability, revealing that while many pavilions proclaim intentions of reuse, only a few demonstrate tangible second-life scenarios. This comparison highlights the persistence of gaps between design ambitions and their practical realization, as well as the need for clearer regulatory and logistical frameworks supporting reuse. The second part translates these insights into practice through an experimental project on recycled gypsum. Conducted within the renovation of the Asanuma Corporation office, it examines how dismantled gypsum boards can be crushed, remixed with natural binders, and reformed into removable acoustic and decorative panels. The results expose both the technical potential and the contradictions of circular design: while hybrid mixtures enhance performance and texture, they also complicate future recyclability. By linking global exhibition architecture with local material experimentation, Matter and Time argues that circularity is not merely a technical solution but a cultural approach. It frames reuse as a design language that redefines waste, value, and the temporal dimension of architectural practice.| File | Dimensione | Formato | |
