Aujourd’hui, de nombreux bâtiments sont démolis lorsqu’ils arrivent en fin de vie ou pour d’autres raisons ; plans urbanistiques, évolutions normatives ou esthétiques peuvent aussi condamner les édifices. Les produits les constituant sont souvent réduits en gravats et difficilement récupérables. Leur tri puis recyclage, au même titre que les déchets ménagers, deviennent de plus en plus courants. Cependant, opter pour la réutilisation des produits, tels des choix de seconde main, est à la marge, bien que le réemploi soit une pratique ancestrale. Il est donc essentiel que le secteur évolue pour permettre le développement de ces pratiques et réformer les manières de concevoir, construire, démolir, … pour une architecture circulaire et moins consommatrice de ressources.
Ce travail propose d’explorer, par une revue de la littérature, la place du réemploi au sein de la mutation circulaire du secteur de la construction ainsi que les étapes de la chaine de valeur actuelle du réemploi. Il investigue ensuite les obstacles à la massification du réemploi en s’intéressant à la dernière étape permettant de fermer la boucle : le matchmaking. Les processus permettant de lier l’offre en produits de réemploi à la demande sont parcourus en s’intéressant aux acteurs qui émergent et se spécialisent dans le réemploi. Des entretiens de ces acteurs sont réalisés à cet effet.
Ces entretiens mettent en lumière comment fonctionnent les processus de matchmaking de manière individuelle mais aussi comment les processus s’articulent les uns avec les autres. Ils discutent des différents aspects du matchmaking : de l’importance de la collaboration entre les acteurs spécialisés dans le réemploi à l’évolution des outils pour transmettre les informations des gisements, en passant par la mutation des rôles des acteurs ou encore l’influence des normes. Ce mémoire propose en somme d’étudier l’étape du matchmaking mais aussi et surtout de revisiter la métaphore de la chaine à maillons du réemploi. Today, many buildings are demolished when they reach the end of their life cycle and for other reasons; urban planning, normative or aesthetic developments can also condemn buildings. The products they contain are often reduced to rubble and difficult to recycle. Sorting and recycling them, in the same way as household waste, is becoming increasingly common. However, opting for the reuse of products, like second-hand choices, is on the bangs, even though reuse is an ancestral practice. It is therefore essential for the sector to evolve to allow the development of these practices and to reform the ways we design, build, demolish, ... for a circular and less resource-consuming architecture.
Through a literature review, this Master’s thesis explores the place of reuse within the sector's circular transformation, as well as the stages in the current reuse value chain. It then investigates the obstacles to the massification of reuse, focusing on the final stage in closing the loop: the matchmaking. The processes that links the supply of reuse products to demand are explored by focusing on the innovative stakeholders who are emerging and specializing in reuse. Interviews are conducted with these stakeholders.
These interviews highlight not only how matchmaking processes work individually, but also how the processes fits together. They discuss all aspects of matchmaking: from the importance of collaboration between stakeholders specialized in re-use to the evolution of tools for transmitting information on deposits, to the changing roles of other stakeholders and the influence of norms. In short, this Master’s thesis proposes to study the matchmaking stage, but also and above all to revisit the metaphor of the reuse chain of links.

The sharing economy and collaborative consumption are attracting a great deal of interest due to their business, legal and civic implications. The consequences of the spreading of practices of sharing in urban environments and under daily dynamics are underexplored. This Special Issue aims to address if and how sharing shapes cities, the way that spaces are designed and lived in if social interactions are escalated, and the ways that habits and routines take place in post-individualistic society. In particular, the following key questions are of primary interest: Urban fabric: How is ‘sharing’ shaping cities? Does it represent a paradigm shift with tangible and physical reverberations on urban form? How are shared mobility, work, inhabiting reconfiguring the urban and social fabric? Social practices: Are new lifestyles and practices related to sharing changing the use and design of spaces? To what extent is sharing triggering a production and consumption paradigm shift to be reflected in urban arrangements and infrastructures? Sustainability: Does sharing increase the intensity of use of space and assets, or, rather, does it increase them to meet the expectations of convenience for urban lifestyles? To what extent are these phenomena fostering more economically-, socially-, and environmentally-sustainable practices and cities? Policy: How can policy makers and municipalities interact with these bottom-up and phenomena and grassroots innovation to create more sustainable cities? Scholars responded to the above questions from the fields of urban studies, urban planning and design, sociology, geography, theoretically-grounded and informed by the results of fieldwork activities.
