Research Project

As part of the energy transition of the territories, analysis of the methanization units as a case of application of the circular economy: analysis focused on the governance of actors and the circularity/territorialization of biomass-energy flows

  • Modes of specification, activation and anchoring of local biomass resources by actors
  • Spatio-temporal dynamics of proximity between actors
  • Management of biomass-energy flows by actors
  • Contribution of actors to the ecological transition of territories
  • Clarification of the circular economy model in terms of territoriality and circularity of resources
  • Contribution to the theoretical reinforcement of the link between proximities and industrial and territorial ecology
