In this present study, the production of poly (butylene succinate) (PBS) from food waste was investigated and critical factors were evaluated. The economic feasibility of the process was investigated, as well as the minimum selling price (MSP) of PBS and sensitivity analysis of economic factors based on critical input parameters. 1,4-butanediol price and solvent usage in PBS purification significantly impacted economics during the process. In this process, the MSP of PBS was 3.5 $/kg. The Monte Carlo simulation technique was used to determine the uncertainty in the MSP of PBS. The plant's return on investment (ROI), payback period, internal rate of return (IRR), and net present value (NPV) were 15.79 %, 6.33 years, 16.48 %, and 58,879,000 USD, respectively. The environmental impact factors were evaluated. The results showed the GHG emission from the process was 5.19 kg CO-eq/kg of PBS which is low than conventional PBS production.
在本研究中，我们研究了从食品废物中生产聚丁二酸丁二醇酯（PBS）的方法，并评估了关键因素。我们研究了该工艺的经济可行性，以及 PBS 的最低销售价格（MSP）和基于关键输入参数的经济因素的敏感性分析。1,4-丁二醇价格和 PBS 净化过程中的溶剂使用量对工艺的经济性有重大影响。在该过程中，PBS 的 MSP 为 3.5 美元/千克。我们使用蒙特卡罗模拟技术来确定 PBS 的 MSP 的不确定性。工厂的投资回报率（ROI）、投资回收期、内部收益率（IRR）和净现值（NPV）分别为 15.79%、6.33 年、16.48%和 58879000 美元。我们还评估了环境影响因素。结果表明，该工艺的温室气体排放量为 5.19 千克 CO-eq/kg PBS，低于传统 PBS 生产。
