The article quantifies, in a set of 23 countries, the amounts consumed of vegetable oils, the amounts of used oils produced after cooking, the amounts available for valorisation, and finally the quantities being valorised. The management practices adopted are also reviewed. Based on data collected, a production factor, relating vegetable oil consumption with used cooking oil production, of 0.32 is proposed. The valorisation factor, which quantifies the fraction of UCO being valorised, is higher in better performing countries (0.749) and worst in the remaining (0.232). Three consumption-valorisation factors, relating consumption with valorisation, were obtained: for high performing countries (0.274); intermediate performing (0.105); and under-performing (0.078). The management systems adopted by the different countries are based on either second-generation economic instruments (USA and Brazil), or on third-generation economic instruments (EU, Argentina, Japan). The former has allowed countries to attain better valorisation rates.
该文章对23个国家的植物油消费量、烹饪后产生的废油数量、可用于回收利用的数量以及最终回收利用的数量进行了量化。同时还回顾了所采用的管理措施。根据收集到的数据，提出了一个将植物油消费与废食用油生产相关联的生产系数，为0.32。回收利用系数用于量化废食用油的回收利用比例，在表现较好的国家较高（0.749），在其他国家则较低（0.232）。得出了三个将消费与回收利用相关联的消费-回收利用系数：表现优异的国家为（0.274）；表现中等的国家为（0.105）；表现欠佳的国家为（0.078）。不同国家采用的管理系统要么基于第二代经济手段（美国和巴西），要么基于第三代经济手段（欧盟、阿根廷、日本）。前者使这些国家能够实现更高的回收利用率。
