This is an exploration of the concept of urban circularity and how it might enhance urban resilience. This thesis defines the different concepts of resilience, circularity, sustainability and their relationship, benchmarks urban circularity initiatives and concludes with an analysis of different frameworks for assessing urban circularity and urban resilience.

Le modèle économique linéaire que nous suivons depuis la révolution industrielle n’est plus soutenable pour les générations futures. Ses limites ont été atteintes et il est aujourd’hui nécessaire de passer à un modèle qui tienne compte de la raréfaction grandissante des ressources et qui limite notre production de déchets et demande en énergie, comme le montre la crise environnementale actuelle. L’économie circulaire a été proposée en réponse à ces constats. Le secteur de la construction, en tant que grand consommateur, peut fortement contribuer à ce changement. Bruxelles-Capitale entend même intégrer ce modèle dans sa région avec son Programme Régional en Économie Circulaire. Afin de comprendre de quelle(s) manière(s) l’économie circulaire peut s’implémenter dans un projet d’architecture, l’étude suivante analyse trois projets de reconversion bruxellois et les stratégies circulaires mises en place dans chacun d’eux. The linear economic model we have been following since the industrial revolution is no longer sustainable for future generations. Its limits have been reached and it is now necessary to move to a model that takes into account the increasing scarcity of resources and limits our production of waste and energy demand, as shown by the current environmental crisis. The circular economy has been proposed as a response to these findings. The construction sector, as a large consumer, can strongly contribute to this change. Brussels-Capital even intends to integrate this model in its region with its Regional Program in Circular Economy. In order to understand in which way(s) the circular economy can be implemented in an architectural project, the following study analyses three Brussels reconversion projects and the circular strategies implemented in each of them.

In recent years, there has been increasing attention to lighting energy efficiency, due to economics - lower energy costs - and environmental reasons - man-induced climate change. Driven by strict energy-efficiency requirements, the lighting industry started to replace the traditional lamps with LED lighting solutions, ignoring the limits of their maintenance and recycling. Faced with an increasing global population, rising resource consumption, and associated negative environmental impacts, shifting from a traditional economic linear model to a more sustainable paradigm of growth is now becoming increasingly urgent. Whereas the topic of circular economy has been widely investigated in literature in the past, little attention has been reserved for the different evaluation tools to assess and improve product circularity and how companies can become more resource efficient. Hence, the present thesis investigates the implementation of a circular economy in the lighting industry using circularity indicators and eco-design strategies. Concerning the real luminaires products, the role of the luminaire in the circular economy and recycling industry is explored, highlighting the limits of their End-of-life process. The main conclusions of the thesis reveal the significance of initial product development, reuse, remanufacturing, and repair strategies in a transition towards a circular economy.

Smart Solutions for Wastewater: Road-mapping the Transition to Circular Economy, the latest release in the Current Developments in Biotechnology and Bioengineering presents up-to-date information on research and technological developments of resource recovery in wastewater treatment in terms of carbon, nutrients and energy. The book fulfils the gaps and current challenges that hinder the application of resource recovery facilities in wastewater treatment plants, discusses knowledge gaps, provides future research perspectives, and discusses strategies to solve problems from a circular economy perspective. It is an excellent, interdisciplinary and updated overview of technologies in terms of potential yields, pollutants removal, nutrients recovery and energy production.

Textile and fibre chemistry form the theoretical basis to understand production and properties of textile based products. In this 2nd edition fundamentals of textile chemistry and theoretical and applicatory aspects of colour chemistry are interconnected to draw detailed picture of chemical reactions occurring during production and modification of textile products. An overview about chemical modification, finishing operations is given to explain how to impart special functionalities into functional products. Examples for technical scale processes and representative machinery used therein give insight into the technical reality of a dyehouse. A new chapter about circularity of textiles highlights the interlinkage between product design, including dyes and finishes, and the requirements to develop future fibre-to-fibre recycling. The work covers all relevant aspects of a textile product from fibre production, coloration, finishing, consumer use and fibre-to-fibre recycling. The content of the book allows a first entry into this multi-disciplinary field. Through its comprehensive character the authors explain the interdependence between textile and fibre processing and aspects of recycling, which makes the work a valuable source of information to design future textiles for circularity.
