Abstract
As the push for designing sustainable processing plants increases, the need for adequate tools to analyze and optimize these plants becomes paramount. Particularly the agricultural sector is in need of new and innovative biorefineries capable of handling the generated waste and transforming them in to added value products. Superstructure optimization offers an elegant solution to explore many alternative processing routes with one or multiple objectives in mind such as, sustainable and financial criteria. Various user friendly and accessible superstructure optimization tools for process design already exist but do not provide the capability to make decisions under uncertainty. This contribution aims to extend the OUTDOOR software package to handle superstructure optimization problems under uncertainty, using a 2-stage approach with fixed recourse. A case study is presented showcasing the extended OUTDOOR application on a processing plant that transforms potato peels into added value products. From the stochastic solution the most beneficial processing route, while considering all the uncertainties, lies in the production of phenolic compounds next to the production of starch, generating an expected revenue of 0.89 million euros per year. The value of perfect information (EVPI) was calculated to be 0.02 million euros, indicating the price of perfect information. The value of the stochastic solution (VSS) was 0 euros, indicating that the produced flowsheet is the most optimal one, across all uncertain scenarios.
