The aim of this article is to evaluate the potential use of biodiesel produced from waste cooking oil in Mexico City. The study is divided in two main areas: the analysis of a waste cooking oil collection pilot project conducted in food markets of a Mexico City region; and the exhaust emissions performance of biodiesel blends measured in buses of the Mexico City public bus transportation network (RTP). Results from the waste cooking oil collection pilot project show that oil quantities disposed depend upon the type of food served and the operational practices in a cuisine establishment. Food markets' waste cooking oil disposal rate from fresh oil is around 10%, but with a very high standard deviation. Emission tests were conducted using the Ride-Along-Vehicle-Emissions-Measuring System in two different types of buses while travelling a regular route. Results shows that the use of biodiesel blends reduces emissions only for buses that have exhaust gas recirculation systems, as analysed by repeated measure analysis of variance. The potential use in Mexico City of waste cooking oil for biodiesel is estimated to cover 2175 buses using a B10 blend.
本文旨在评估墨西哥城利用废弃食用油生产生物柴油的潜在用途。该研究分为两个主要领域：对在墨西哥城一个地区的食品市场开展的废弃食用油收集试点项目进行分析；以及在墨西哥城公共巴士运输网络（RTP）的巴士上测量生物柴油混合物的尾气排放性能。废弃食用油收集试点项目的结果表明，废弃的油量取决于所供应食物的类型以及烹饪场所的运营方式。食品市场新鲜油的废弃食用油处理率约为10%，但标准差非常高。使用随车排放测量系统在两种不同类型的巴士行驶常规路线时进行了排放测试。结果表明，通过重复测量方差分析，生物柴油混合物的使用仅能减少配备废气再循环系统的巴士的排放。据估计，在墨西哥城，废弃食用油用于生物柴油的潜在用途可满足2175辆使用B10混合物的巴士。
