Our current context, which is marked by the acceleration of climate change, the scarcity of resources and geopolitical tensions, calls for a review of the French energy strategy, with biomass-energy as the main source of renewable energy. The roadsides along French roads make up nearly 5,000 km² of the territory and constitute a biomass potential that has not yet been exploited. Thus, if one is to look at roadsides from a new perspective, and consider them as a potential source of sustainable bioeconomy, then a change in practices will be required in order to be able to better exploit this potential. Several studies have highlighted the importance of territorial demonstrators for the implementation of practices and emerging supply chains. With this in mind, this article proposes a conceptual framework for the implementation of a demonstrator for the sustainable management of roadsides for valorization purposes, based on the cross-referencing of information taken from the literature on demonstrators and the sustainable sector.
