Optimal planning and site selection for distributed multiproduct biorefineries involving economic, environmental and social objectives.

摘要: Abstract Biorefineries appear to be a viable solution replace traditional fossil fuel refineries, but their implementation requires the exploration of several aspects, including feedstock selection, processing routes, products, harvesting sites, and markets, as well numerous other sustainability criteria. The optimal these problems is not immediately obvious. Therefore, this study presents an optimization model design plan sustainable biorefinery supply chains that considers relevant issues. These issues include multiple available biomass feedstocks at various availability seasonality resources, different potential geographical locations for plants produce products using diverse production technologies, economies scale demands prices in each market, storage facilities number transportation modes between chain components. Sustainability considerations are incorporated into proposed by simultaneous economic, environmental social performance data evaluation designs. problem was formulated multi-objective, multi-period, mixed-integer linear program seeks maximize profit chain, minimize its impact jobs generated implementation. measured Eco-indicator99 according life-cycle assessment technique, objective quantified generated. Pareto-optimal solutions were obtained e-constraint method. To illustrate capabilities multi-site system model, case presented addresses planning fulfill expected ethanol biodiesel Mexico. results indicate cost-effective can satisfy Mexican demand choosing year-round do significantly adversely environment. Furthermore, implementing would have significant impact.
