In this study, a multi-period model of an organic waste-to-biodiesel phased supply chain network is developed to strategically consider variations in the biodiesel demand and the organic waste usage over a long-term planning interval. The proposed model can facilitate planning to determine the biorefinery location and the amount of biodiesel to produce, transport, or utilize to reduce the total cost of the organic waste-to-biodiesel supply chain network design while meeting the biodiesel demand during each period of the planning interval. The features and capabilities of the model are validated by application of a future organic waste-to-biodiesel supply chain network design in South Korea. The optimization results illustrate that the average total annual cost of the organic waste of biodiesel based on the multi-period model will be $US 4.2 billion per year during the period 2020–2030. The minimum selling prices for the optimal network design were determined ranged from $US 3.154–3.156/gallon of biodiesel containing 3% butanol derived from organic waste combined with diesel. A small portion (4.9–6.6%) of the total biodiesel demand was produced from organic waste because of low organic waste availability in the existing anaerobic digestion facilities, leading to increasing the outsourcing costs of butanol. The proposed approach will facilitate the strategic development of a sustainable supply chain network for organic waste recycling for material and energy valorization.

在这项研究中，开发了有机废物到生物柴油分阶段供应链网络的多周期模型，以战略性地考虑长期规划间隔内生物柴油需求和有机废物使用量的变化。提议的模型有助于规划确定生物精炼厂的位置和生产、运输或利用的生物柴油量，以降低有机废物到生物柴油供应链网络设计的总成本，同时满足每个时期的生物柴油需求。计划间隔。该模型的特性和功能通过在韩国应用未来有机废物到生物柴油供应链网络设计得到验证。优化结果表明，基于多期模型的生物柴油有机废物的年平均总成本为 4 美元。2020-2030 年期间每年 20 亿。最佳网络设计的最低销售价格确定为 3.154 美元至 3.156 美元/加仑的生物柴油，其中含有 3% 来自有机废物和柴油的丁醇。由于现有厌氧消化设施中有机废物的可用性较低，因此生物柴油总需求的一小部分（4.9-6.6%）来自有机废物，导致丁醇的外包成本增加。拟议的方法将促进可持续供应链网络的战略发展，用于有机废物回收以实现材料和能源的增值。156/加仑的生物柴油含有 3% 的丁醇，源自有机废物和柴油。由于现有厌氧消化设施中有机废物的可用性较低，因此生物柴油总需求的一小部分（4.9-6.6%）来自有机废物，导致丁醇的外包成本增加。拟议的方法将促进可持续供应链网络的战略发展，用于有机废物回收以实现材料和能源的增值。156/加仑的生物柴油含有 3% 的丁醇，源自有机废物和柴油。由于现有厌氧消化设施中有机废物的可用性较低，因此生物柴油总需求的一小部分（4.9-6.6%）来自有机废物，导致丁醇的外包成本增加。拟议的方法将促进可持续供应链网络的战略发展，用于有机废物回收以实现材料和能源的增值。
