Push vs Pull replenishment policies in Symbiotic Supply Chains

The circular production approach, based on the continuous recovery of value from waste as raw materials for manufacturing processes, is gaining increasing prominence in companies worldwide. One of the practices that effectively embodies the principles of the Circular Economy is Industrial Symbiosis. The aim of this work is to compare different replenishment policies – push and pull – in the Symbiotic Supply Chain archetype. The results reveal that the pull policies offer more balanced performance across multiple indicators preserving consistent dynamic performance and efficient inventory management, also for high volume of waste.
