Abstract：
Techno-economic assessment (TEA) of a valorization of bulking agent (BA) ratios on the food waste compost value chain is made to assess economic feasibility. TEA was performed with two plans (Plan A: existing composting facilities; Plan B: new composting facilities) and each plan was under four scenarios. The BA (i.e. corn stalks, garden waste, and watermelon seedlings) ratio of 5 % (S1), 10 % (S2), 20 % (S3), and garden waste with a ratio of 20 % (S4). Results indicate that S2, with a net present value (NPV) of 128.9 million, represents Plan A\'s most economically viable scenario. Although the total operating costs of S4 were 18.9 %-23.5 % higher, 25.6 %-42.2 % higher total revenue made S4 have an NPV of 92.9 million, making it the most viable scenario in Plan B. All scenarios show positive NPV within a ± 20 % fluctuation range. Organic fertilizer price, government subsidies, and processing capacity were the key factors influencing NPV.
摘要：
对食物垃圾堆肥价值链上的膨胀剂（BA）比率进行了技术经济评估（TEA），以评估经济可行性。TEA有两个计划（计划A：现有的堆肥设施；计划B：新的堆肥设施），每个计划都在四种情况下进行。BA(即玉米秸秆，花园垃圾，和西瓜幼苗)比例为5%(S1)，10%(S2),20%（S3），和比例为20%的花园垃圾(S4)。结果表明，S2的净现值(NPV)为1.2890亿，代表计划A的最经济可行的方案。尽管S4的总运营成本高出18.9%-23.5%，总收入增加25.6%-42.2%，使S4的净现值为9290万，使其成为B计划中最可行的方案。所有方案均在±20%的波动范围内显示出正的净现值。有机肥价格,政府补贴,和加工能力是影响净现值的关键因素。
