Abstract— This study utilized a central composite design (CCD) with the aim of attaining the ideal circumstances for multi-objective optimization (MOOP) so as to convert cooking oil waste into useable biodiesel. Reducing the overall capital cost ( ) and lowering the cost of procedures ( ) comprised the primary functions of MOOP. To resolve issues and contrast them with other techniques in Meta-heuristic to 5 well-known approaches, the Grey Wolf Optimizer (GWO) technique was applied. In an effort to establish the settings that offer optimization for the process used in biodiesel manufacturing, this research carried out an experiment employing CCD. Because it is one of the most commonly employed programs known to deliver valuable results, CCD was selected for the development of thirteen parameters. To assess the influences of the independent parameters on the mass fraction of FAME, % FAME purity, the mass fraction of glycerol, and % glycerol purity was included in the creation of this experimental set using CCD. The overall capital cost was US $8,302,990, while the operations cost was US $1,731,277 per year, as demonstrated by supplementary research involving optimization by CCD. It was revealed that a cost savings of roughly US $1,060 and US $6,310 annually was possible for overall capital cost and operations cost, respectively, when compared to the original process.
