从废物转化为能源的角度来看，废食用油是除农业废弃物之外的一种有吸引力和可用的回收原料。从废食用油中产生能源被认为是废物管理的有效技术，也是能源回收的有益形式。通过成本效益分析，对两种替代系统和一种传统系统的废弃食用油收集和转化进行了评价，以找到一种合适的废弃物转化为能源的方法。结果表明，废食用油与废润滑油的回收（系统II）是一个有用的替代废食用油的管理（B/C> 1）。还确定了热解油在最大和最小转化率下燃烧产生的总热量。由于所涉及的化学品的成本，在引入热解反应器（系统III）之前进行化学预处理的单独收集废烹饪油被认为是不期望的选择（B/C <1）。虽然系统III不需要化学预处理，因此是一个理想的选择，但燃烧产生的总热量较少。该过程所需的增加的电力成本对系统II的效益-成本比没有影响。然而，系统III，不包括化学预处理，成为一个无利可图的替代品时，电力成本达到100%的固定资本成本在最低转换率。
From the viewpoint of waste-to-energy, waste cooking oil is one of the attractive and available recycled feedstocks, apart from agricultural residues. The generation of energy from waste cooking oil is considered as an effective technique for waste management, as well as a beneficial form of energy recovery. Two alternative systems and a conventional system of waste cooking oil collection and conversion are evaluated by the cost benefit analysis in order to find a suitable method for waste-to-energy conversion. The results show that the collection of waste cooking oil with waste lubricating oil (System II) a useful alternative to the management of waste cooking oil (B/C > 1). The total heat produced by the combustion of pyrolytic oil at maximum and minimum conversion rates is also determined. The separate collection of waste cooking oil, subjected to chemical pre-treatment prior to introduction in a pyrolysis reactor (System III), is considered an undesirable option (B/C < 1) due to the cost of the chemicals involved. Although the exclusion of chemical pre-treatment makes System III a desirable option, the total amount of heat of combustion generated is less. The increased electricity cost required for the process has no effect on the benefit-cost ratio of System II. However, System III, excluding chemical pre-treatment, becomes an unprofitable alternative when the electricity cost reaches 100% of the fixed capital cost at the minimum conversion rate.
