  The article considers the issue of increasing the structural reliability of a
biofuel production plant. A review of the existing basic technological schemes
of the biofuel production plant has been carried out. The main structural
elements are determined and a functional diagram is constructed. Processed
cooking oil was chosen as the input raw material. A structural analysis of the
reliability of each element and the entire system as a whole was carried out.
The least reliable elements are determined, options for improving the overall
reliability of the installation are proposed.
