In this study, techno-economic analysis of the sustainable production of polylactic acid (PLA) and biodiesel from Food Waste (FW), with a plant capacity of 50 tons/day, was investigated. In addition, FW of four countries (China, India, Brazil, and the USA) with different compositions of water, protein, lipid and carbohydrate were proposed. Each country has different PLA production rates based on carbohydrate and biodiesel production based on fat. In this study, the FW composition of the USA shows better economic feasibility than other countries. The actual minimum selling price is 6.53 (China), 5.35 (India), 4.75 (Brazil), and 4.29 (US) $/kg. The uncertainty of the MSP was analyzed based on various input limits. The sensitivity analysis was conducted based on biodiesel-selling price, PLA-selling price, income tax, and project lifetime on techno-economic analysis parameters, such as ROI, payback period, IRR and NPV were investigated.
本研究对 50 吨/天产能的食品废物（FW）可持续生产聚乳酸（PLA）和生物柴油进行了技术经济分析。此外，还提出了来自中国、印度、巴西和美国四个国家的 FW，它们的水、蛋白质、脂质和碳水化合物组成各不相同。每个国家的 PLA 产量基于碳水化合物，生物柴油产量基于脂肪。在这项研究中，美国 FW 的组成具有比其他国家更好的经济可行性。实际最低销售价格为 6.53（中国）、5.35（印度）、4.75（巴西）和 4.29（美国）$/kg。根据各种输入限制对 MSP 的不确定性进行了分析。基于生物柴油销售价格、PLA 销售价格、所得税和项目生命周期，对技术经济分析参数（如 ROI、投资回收期、IRR 和 NPV）进行了敏感性分析。
