An integrated optimization model for an organic-waste-derived butyric acid-to-butanol supply-chain network (BABSCN) is proposed to minimize the total network cost by simultaneously optimizing both strategic biodiesel production and waste management planning decisions. This model is useful for ensuring effective organic-waste provision for large-scale biodiesel production and waste management. The proposed mixed-integer linear-programming model optimizes the activities ranging from organic-waste preprocessing to butyric acid (BA), transportation of BA to biorefinery, butanol (BuOH) production and mixing with diesel to the distribution of biodiesel. This model is useful for forecasting organic-waste management biodiesel supply chains in South Korea in 2030. The case study results show that a total network cost of $US 3.16/gallon of B3 contains 3% BuOH from organic waste products combined with diesel. The biorefinery-related cost accounts for 98.3% of the total network cost, followed by the organic waste procurement cost (1.1%) and biodiesel distribution cost (0.6%). A scenario-based analysis shows that a 7%-BuOH increase in biodiesel increases the total network cost by 18.8%.
提出了一个有机废物衍生丁酸到丁醇供应链网络（BABSCN）的综合优化模型，通过同时优化战略生物柴油生产和废物管理规划决策，最小化总网络成本。该模型有助于确保为大规模生物柴油生产和废物管理提供有效的有机废物。所提出的混合整数线性规划模型优化了从有机废物预处理到丁酸（BA）、BA 运输到生物精炼厂、丁醇（BuOH）生产以及与柴油混合到生物柴油分配的活动。该模型可用于预测 2030 年韩国的有机废物管理生物柴油供应链。案例研究结果表明，总网络成本为 3.16 美元/加仑的 B3 中含有 3%的 BuOH 来自与柴油混合的有机废物产品。与生物精炼厂相关的成本占总网络成本的 98.3%，其次是有机废物采购成本（1.1%）和生物柴油分配成本（0.6%）。基于情景的分析表明，生物柴油中 BuOH 增加 7%会使总网络成本增加 18.8%。
