Comparative case study of the construction and demolition waste practical treatment induced by different legislations in France and Belgium (Wallonia and Flanders)

A comparative case study of the current legislation and state of the art of practical procedures and methodologies used for the treatment of Construction and Demolition Waste (CDW) between France and Belgium (Flanders and Wallonia) will be presented in the framework of the project VALDEM (Interreg Va France-Wallonie-Vlaanderen Convention n°1.1.57). The authors exhibit the differences in practice for the demolition companies induced by different policies at regional or national level. Typical examples are given concerning the various mandatory phases of a demolition work, their organization, with a link to the resulting quality of CDW (number and type of waste stream collected, purity of each stream, and identification of the undesired material). Emphasis will be put on the technical feasibility versus the legal feasibility for each region. Existing valorization routes are also mentioned in order to show potential transnational opportunities for the CDW industries, the sorting facilities, and potential end users, and in general help transposing the good practices from one region/country to another
