【 摘 要 】
Today, the flows of materials in the French building sector are poorly known, both in terms of quantities or types of recovery (reuse, recycling, energy recovery, etc.). Therefore, the aim of this study is to increase the knowledge about recovery of building products in France. A methodology is developed to identify the flows of materials resulting from the deconstructions of buildings. The volume of demolished buildings for each typology (individual house, apartment building, office building...) and constructive system (brick, concrete, wood...) is known from the state of the art. Moreover, the quantities of demolished materials are estimated for each building typology from a French database of building waste diagnosis. Then, the volume of waste can be calculated for all the building sector and the deconstruction flows can be crossed with an analysis of the existing types of recovery (projects of close development, recycling channels, ...). This analysis will present the distribution of the different ways of recovery for each type of material and the associated costs. This capitalization of data on waste flows and building resources will allow to question the adequacy between material needs and available resources.
