This study aimed to assess how physicochemical factors affected the efficiency of the process for producing biodiesel from oily residues in fishing industry effluent. The oil extracted from the grease traps was initially characterized for the stabilization of the process' influential parameters, obtaining viscosities of 38 mPa/s, densities of 0.93 g/ml, and saponification indices of 260.40 mg KOH/g; it was then necessary to neutralize the oil and dry it to reduce the oil's acidity to 0.97% and its humidity to 0.03%, in order to meet the conditions for subsequent transesterification, This led to the conclusion that T7 (80 ºC, 9:1, and 0.8%) was the best treatment. It produced a 94% performance of biodiesel extraction and had the following properties: acidity of 0.39 mg KOH/g, viscosity of 2.7 mPa/s, ashes of less than 0.02%, density of 883.7 kg/m3, flash point of 120 ºC, and cetane index of 41. However, it had a high-water content.
