Abstract : Our society is constantly evolving and positioning itself in relation to the world around it. This evolution pushes it to reorganize itself around energy from local and more renewable sources. For these reasons, it seems appropriate to design a possible evolution of anaerobic digestion (AD) by localized units. This is referred to a micro-AD at urban scale. The purpose of this thesis was to provide some answers to the question of the feasibility of integrating this micro-AD into a neighbourhood.To this end, it was carried out: i) An analysis of feedback from cities with urban AD projects. ii) An experimental approach, with the aim of obtaining a stable AD process of urban waste atlaboratory scale. iii) These input data then made it possible to establish a waste recovery model in a district. These results highlight the need for a systemic approach in order to be able to integrate AD in a neighbourhood. They also make it possible to recommend processes and wastes, in order to improve the implementation of the process in urban areas. Under defined conditions, urban AD is possible and stable over time. In addition, the energy balance is beneficial for the district. It should be noted that the energy thus produced is mainly in the form of heat, which highlights the importance of an integrated process, close to homes.
