Abstract
As global consumption and population growth accelerate, the efficient use of finite resources has become a significant concern in developing sustainable manufacturing models. Consequently, the circular economy is gaining attention, aiming to extend resource life cycles.
Industrial symbiosis (IS) fosters eco-collaboration between at least two participants, where a manufacturer’s unavoidable residue flow, known as a byproduct, is revalorized as a substitute raw material for another. As a key circular strategy in manufacturing, IS aims to enhance coordination among collaborators to reduce environmental and supply costs while creating market opportunities and strengthening supply resilience. A notable example of IS application is the Kalundborg Industrial Park in Denmark, where symbiotic exchanges of water, energy, and materials among various collaborators highlight the potential for cross-industry collaboration.
While IS is widely studied at a strategic level, its tactical implementation in production planning remains underexplored, particularly under uncertainty. Byproduct yield variability impacts the byproduct availability, reliability among collaborators, and willingness to engage in the partnership. Our study addresses this challenge by incorporating yield uncertainty into lot-sizing optimization within an IS network, bridging the gap between strategic and tactical level planning.
