摘要

背景:由于对能源的需求不断增长,以及与使用化石燃料有关的环境问题,寻找替代能源变得极其重要。柳枝稷生产的生物乙醇被认为是化石燃料的最佳替代品之一。方法:本研究开发了一种两阶段供应链建模方法,首先通过地理信息系统(GIS)分析确定北达科他州建造柳枝稷生物精炼厂的可行地点。在第二阶段,通过开发一个旨在将生物乙醇生产商业化的混合整数线性计划,最大限度地提高相应的基于柳枝稷的生物乙醇供应链的利润,同时包括能源使用和碳排放成本对供应链决策和生物精炼厂选址的影响。结果:数值结果表明,碳排放和能源消耗惩罚影响最优生物炼制选择和供应链决策。结论:我们得出的结论是,没有必要同时惩罚排放和能源使用,以实现理想的环境效益,否则,供应链将变得无利可图。此外,实施排放或能源消耗惩罚使优化模型更接近供应源,同时具有更高的土地租赁成本。这些政策将促进可持续的第二代生物质生产,从而减少对化石燃料的依赖。

Location Allocation of Biorefineries for a Switchgrass-Based Bioethanol Supply Chain Using Energy Consumption and Emissions
Background: Due to the growing demand for energy and environmental issues related to using fossil fuels, it is becoming tremendously important to find alternative energy sources. Bioethanol produced from switchgrass is considered as one of the best alternatives to fossil fuels. Methods: This study develops a two-stage supply chain modeling approach that first determines feasible locations for constructing switchgrass-based biorefineries in the state of North Dakota by using Geographic Information Systems (GIS) analysis. In the second stage, the profit of the corresponding switchgrass-based bioethanol supply chain is maximized by developing a mixed-integer linear program that aims to commercialize the bioethanol production while impacts of energy use and carbon emission costs on the supply chain decisions and siting of biorefineries are included. Results: The numerical results show that carbon emissions and energy consumption penalties affect optimal biorefinery selections and supply chain decisions. Conclusions: We conclude that there is no need to penalize both emissions and energy use simultaneously to achieve desirable environmental benefits, otherwise, the supply chain becomes non-profitable. Moreover, imposing emissions or energy consumption penalties makes the optimization model closer to supply sources while having higher land rental costs. Such policies would promote sustainable second-generation biomass production, thus decreasing reliance on fossil fuels.
