Abstract: In Colombia, different varieties of avocados are produced. In the Montes de María region, Creole-Antillean avocados are grown, but part of the production is lost due to the presence of fungi and pests, lacking marketing strategies, poor road conditions, and other factors. For this reason, we propose utilizing avocados under the concept of biorefinery to produce value-added products such as bio-oil, biopesticide, and chlorophyll from the pulp, seed, and peel, respectively. The objective is to evaluate the safety of establishing an avocado biorefinery by determining the inherent safety index of the chemical processes. The process inherent safety index is a methodology that allows the assessment of processes in the conceptual design stages. This technique identifies the characteristics of the process by determining the properties of the chemical substances, maximum operating conditions, types of equipment, construction materials, reported accidents, and other relevant factors. In the present study, the safety performance of the process is observed. A total inherent safety index of 18 points was obtained, indicating that the process is viable from a safety perspective if we compare it to the permitted limit of 24 points. This is because the process does not represent a considerable safety hazard, though some precautions must be taken due to the maximum operating temperature of 81 °C. Additionally, the chemical substances (methanol, acetone, and ethanol) necessary for obtaining bio-oil, chlorophyll, and biopesticide must be handled appropriately.
