Process integration is a technique that allows systems to be synthesized based on optimized component interactions. It can be applied to multiple plants to facilitate planning of industrial symbiosis. It involves the interactions created from the exchange of products and commodities rather than each plant obtaining their raw materials externally. Industrial symbiosis of multiple plants leads to higher economic benefits and reduced environmental impact. However, problems arise from the involvement of multiple owners of plants and the uncertainty in the demand of the end products. In this study, a neutrosophic mathematical programming model is developed to capture the behavior of decision-makers considering sharing economic benefits. The neutrosophic nature of profit aspiration levels involve three components of membership, non-membership, and indeterminacy. The membership function represents the satisfaction of each owner’s optimistic profit goal. On the other hand, the non-membership function represents the dissatisfaction of the owner with the pessimistic profit share. The indeterminacy function represents hesitancy with higher profit levels due to product demand uncertainty. A case study composed of power generation, hydrogen production, and methanol production is used to illustrate the model. The case study results show that synergistic interaction between plants enables the allocation of a 127 % increase in profit margin for methanol production. A decrease of 24 % in CO2 emissions is also observed from the case study.
