Cost Analysis of Cacao (Theobroma cacao L.) Plant Propagation through the Somatic Embryogenesis Method

In vitro cacao (Theobroma cacao L.) production via somatic embryogenesis (SE) is being implemented to mass propagate clonal plant material with the donor material’s prominent characteristics. Though it is an advanced technology, it is con-sidered expensive compared to other propagation techniques. This work focused on identifying the critical financial feasi-bility factors for the SE productive process. The process's costs were estimated, identifying factors influencing each la-boratory's standardized ES process. A Monte Carlo Simulation (MCS) was performed to evaluate different variables upon increasing productive scale in a biofactory (commercial-scale production). The projected lot volume was 100,000 plantlets in solid media, considering the process flow from in vitro introduction to acclimation. A biofactory operational model was projected, establishing time and operator movements and identifying direct and indirect costs. Costs were defined by the standardized or integral method, with estimated and budgeted calculations to set the cost per plantlet. The identified cost components were culture medium (CM), indirect manufacturing costs (IMC), labor (direct and indirect) and operating expenses. Labor had the most significant share of the costs, at 53%, followed by operating expenses, at 30%, CM, at 12%, and IMC, at 5%. The MCS helped define that the variables with the highest impact on unit price were the embryos’ response in the germination-acclimation stage and the proliferation coefficient during the maturation stage. This projection yielded a figure of US $0.73 per plantlet. However, strategies to reduce this cost have been proposed. These strategies are mainly conducive to optimizing labor and implementing practices that increase multiplication.
