Modeling the Impact of Ecological Preferences on Circular Economy[Modélisation multi-agents d'un marché local de flux résiduels]

Industrial symbiosis (IS) is a key mechanism of circular economy, enabling firms to reuse industrial byproducts as productive inputs. However, IS-focused approaches typically consider only firms exchanges and neglect the role of final consumers, which limits their ability to represent the full dynamics of circular economy. This paper extends a spatially explicit agent-based model, in which heterogeneous firms trade residual resources locally and prices emerge endogenously from transport costs, disposal penalties, and adaptive pricing strategies. While this baseline captures the emergence of industrial symbiosis, it is not sufficient to model circular economy dynamics. We therefore extend the framework toward a full circular economy by incorporating production cycles, final consumers, and environmental attributes of products.
