Abstract

This article reports the results of a comparative analysis of biodiesel production from two major summer oilseed crops, accounting the economic risk of production. The objective is to provide the necessary knowledge for the feasible adaptation of oilseed crops for on-farm production of biodiesel. Investment in small-scale biodiesel processing units for on-farm production was investigated at three different stages, namely the production of oilseed, processing of oil and processing of biodiesel. The annualized net revenue from the biodiesel production was calculated considering a 15-year time period. The results show the potential for a positive return from biodiesel production; however, there is a potential for negative return under low-yield scenarios. According to Monte Carlo simulation, the profit range generated across random samples for biodiesel production from both oilseed crops yields a positive net return. The probability of a negative return on biodiesel production from sunflower was lower than that from soybean.

摘要

本文报告了对两种主要夏季油籽作物的生物柴油生产进行比较分析的结果，并说明了生产的经济风险。目的是为油籽作物在农场生产生物柴油提供必要的知识。对用于农场生产的小型生物柴油加工厂的投资在三个不同阶段进行了调查，即油籽生产、油加工和生物柴油加工。生物柴油生产的年化净收入是根据 15 年的时间段计算的。结果表明生物柴油生产有可能获得正回报；然而，在低收益情况下有可能出现负回报。根据蒙特卡罗模拟，两种油籽作物生物柴油生产的随机样本产生的利润范围产生了正的净回报。向日葵生产生物柴油的负回报概率低于大豆。
