In this paper, we investigate the potential environmental benefits obtainable in Industrial Symbiotic Networks (ISNs) in case firms stock wastes when the demand is lower than supply. We design multiagent-based simulations to model the spontaneous emergence and operations of ISNs over time where firms are involved in substitution-based symbiotic relationships. In each simulation, we compute: 1) the amount of resources saved with respect to the amount of produced wastes; and 2) the amount of resources not saved because of the lack of inventory compared to the produced amounts. Results show that waste stocking could be a useful strategy to reduce the negative effects of the waste market dynamicity on the match between demand and suppl
