To promote the growth of the biodiesel industry, many countries have started allocating initial inducements to start-up companies to set up the infrastructure for its production facilities. Thus, comprehensive economic assessments are vital to keeping businesses on the right track in the long run. In this present study, net energy ratio (NER) and macroeconomic assessment are investigated using actual data obtained from biodiesel production from waste cooking oil (WCO) by using a semi-industrial plant. The fuel quality produced has complied with the European Biodiesel Standard (EN 14214) and the net energy ratio (NER) calculated was positive, which, in other words, epitomized a competent-designed production practice. Concerning mass balance, 74.3% of biodiesel, 24.0% of by-product glycerol and 8.9% soap were measured. By applying these as baseline values for scale-up production of 3.68 kt per annum, projected values of total production costs, selling price of B10 fuel, net present value (NPV) and internal rate of return (IRR) were USD 1.78 million, USD 0.47/kg, USD 1.43 million and 60%, respectively. In summary, these projected values are suggestively lucrative, offering strong business growth for 10 years and capable of withstanding the variations of plant capacity and raw material price.

为了促进生物柴油产业的发展，许多国家已经开始向初创企业分配初始诱因，以建立其生产设施的基础设施。因此，从长远来看，全面的经济评估对于使企业保持正确的轨道至关重要。在本研究中，使用通过使用半工业工厂从废食用油（WCO）生产生物柴油获得的实际数据，调查了净能量比（NER）和宏观经济评估。生产的燃料质量符合欧洲生物柴油标准（EN 14214），并且计算的净能量比（NER）为正，换句话说，这是合格的设计生产实践。关于质量平衡，测量了74.3％的生物柴油，24.0％的副产物甘油和8.9％的肥皂。通过将这些值用作每年扩大3.68 kt规模生产的基准值，总生产成本，B10燃料的售价，净现值（NPV）和内部收益率（IRR）的预计值分别为178万美元，分别为0.47 / kg，143万美元和60％。总而言之，这些预测值具有可观的利润，可提供10年的强劲业务增长，并能够承受工厂产能和原材料价格的变化。
