Abstract
Recent policies and researches confirm that the circular economy (CE) is indispensable to achieving the ecological transition and sustainable development because it offers strategies to face challenges such as reducing waste production and the scarcity of primary resources. As the construction sector is one of the largest consumers of raw materials, a producer of waste, and a generator of environmental impacts, it becomes a key sector to focus the researchers’ and practitioners’ efforts. This research shows the main challenges and opportunities for communities for planning and implementing CE in the construction sector. At the same time, it presents the principal results of material stock and material flows by waste categories of the buildings sector for the Ile-de-France region. To respond to the challenge of the link between research and stakeholders’ needs, a model with a bottom-up approach and a building description by macrocomponents was developed. The model can be applied to different scales and, at the same time, allows a detailed description of the buildings’ flows to be obtained. The results of the studies will allow the stakeholders to better understand the materiality of their territory, giving them the possibility of making better decisions to implement the reuse and recycling of secondary resources.
