Popis: The main goals of retrofitting strategies are focused on addressing fundamental improvements in energy, environmental, and cost performance. This paper presents a novel formulation model aimed at determining optimal configurations for integrating a multi-energy type system to the process industries. The design and operation tasks are posed in mathematical terms as a bi-criteria mixed-integer linear programming problem (bi-MILP) that seeks to maximize the net present value (NPV) of the process supply chain while minimizing its environmental impact. Hence, the major contribution is the adoption of a mathematical approach to capture the cause-effect relationship between material/energy consumption/demand and the associated environmental impacts. The model capability is validated through a case study based on the Argentinean sugar cane industry and the benefits of integration are demonstrated.
