(B) Optimal supply chain from ethanol processing plant to distribution centers under economic optimization. (C) Optimal supply network from raw material collection station to ethanol processing plant under environmental optimization. (D) Optimal supply chain from ethanol processing plant to distribution centers under environmental optimization. (E) Minimum production cost decomposition under economic optimization. (F) Minimum carbon emissions decomposition under environmental optimization. (G) Pareto optimal curve for trade-offs between economic and environmental goals (Adopted from Jiang et al., 2024) 8 Case Study: Pilot or Regional Sorghum-to-Ethanol Projects 8.1 Example project: (e.g., A pilot project in India, China, or U.S. Midwest) A three-year field pilot was conducted in Fort Valley, Georgia, USA. The main purpose of this trial was to determine whether three sweet sorghum varieties (Dale, M81 E, and Theis) were suitable for ethanol production (Ekefre et al., 2017). The researchers systematically recorded several key points, such as the yield of these sorghum varieties, the amount of juice extracted, the sugar content, and how much ethanol they could theoretically produce.
