The tightening of environmental requirements for shipping raises the issue of optimizing residual marine fuels (RMF). The incorporation of biocomponents into RMF contributes to addressing this challenge, while simultaneously heightening the need to study the impact of fundamentally new fuel systems on their operational suitability, particularly concerning the bacterial contamination, which can lead to biocorrosion of equipment and instability of marine fuel. This work is dedicated to investigating the influence of biocomponents based on recycled waste cooking oil (RWCO) on the microbiological contamination of residual marine fuels, as well as the possibility of controlling it through the use of a biocidal additive for diesel fuel. The study found that the most effective suppression of the microbiological contamination occurs when the biocidal additive is added directly to the biocomponent rather than to the fuel composition of marine fuel. Incorporating 1500 ppm of the additive into the RWCO before mixing with RMF reduced the amount of additive needed by ten times and decreased the initial concentration of colony-forming units (CFU) in the bio-marine fuel by twenty-one times. When producing bio-marine fuel with the inclusion of a biocidal additive in the biocomponent, its compatibility with the medium RWCO should be considered, opening a new avenue for research in this field. The inhibiting properties of the biocidal additive were demonstrated in samples of fuel RMD 180 + (RWCO + 1500), RMD 180 + RWCO + 1500, and RWCO + 1500 over a storage period of five months, and in samples of fuel RMD 180 + (RWCO + 750) and RMD 180 + (RWCO + 150) over a week of storage at temperatures of 50 °C and − 10 °C.
