Abstract: In the last years, renewable energies have been proposed as a solution to mitigate climate change. In this sense, biomass has become a more popular alternative than other sources of renewable energy, such as solar energy and wind power. As its main advantage, biomass is obtained from organic material, which makes it consistent throughout the year. Studies on biomass as a source of energy are usually conducted at a pilot scale to determine its energetic potential. However, there is less emphasis on studying the logistic operations and key variables that enable the feasibility of biomass as a source of energy at an industrial scale. To address this gap, we study the potential of coffee pulp as a source of biomass, and consequently, as a source of energy. To this end, we use the System Dynamics methodology. First, we developed a simulation model where the results indicate that one ton of coffee pulp can produce 180 m3 of biogas, which in turn can generate 0.41 MW of net electricity. Then, we performed a 20-year sensitivity analysis to identify the key variables ensuring electricity generation from coffee pulp which include: harvested area (hectares), cherry coffee yield (ton/ha), and efficient usage of coffee pulp.
