This research explores the optimization of Sustainable Aviation Fuels (SAF) production in Colombia, emphasizing economic and environmental factors. It examines feedstock availability, production technologies Alcohol-to-Jet (ATJ), Fischer-Tropsch (FT), and geographical considerations to determine the Minimum Fuel Selling Price (MFSP) of SAF. The environmental analysis employs a Life Cycle Assessment (LCA), considering CO2 emissions at each value chain step with an energy allocation factor for equitable carbon footprint distribution. Results highlight increased SAF demand in urban centers, necessitating diverse biomass sourcing. Fischer-Tropsch proves efficient but with high energy requirements impacting costs, while Alcohol-to-Jet offers an alternative leveraging existing bioethanol facilities. The study emphasizes data sensitivity importance, addressing limitations and showcasing 0.072 USD/L change for 1% allocation change and 0.03 USD per liter for 1% conversion drop in Gas-to-Liquid Fuel, and 0.04 USD/L for allocation and 0.1 USD/L for 1% conversion drop in Alcohol-to-Jet. Compared to prior work, this research provides detailed economic and environmental insights, extending analysis depth and acknowledging limitations, thereby enhancing research comprehensiveness and applicability.@en

This study assesses the economic and environmental implications of Sustainable Aviation Fuel (SAF) production using Alcohol-to-Jet (ATJ) and Gasification Fischer-Tropsch (GFT) technologies, focusing on Colombian lignocellulosic feedstocks and evaluating key performance indicators such as yield, minimum fuel selling price, and life cycle assessment. GFT demonstrates promising results, yielding and Minimum Fuel Selling Price (MFSP) of about 1.3 USD/L and a Life Cycle Assessment (LCA) of 3.2 to 7.7 gCO2 eq/MJ. However, its scalability is constrained by the volumes it manages. On the other hand, ATJ has an MFSP between 1.9 and 2.4 USD/L. Aligned with aviation industry goals for carbon-neutral growth, this analysis provides valuable insights for policymakers and industry stakeholders, supporting informed decisions toward sustainable aviation fuel adoption in the Colombian context.@en

This article reviews the current scenario and the main uncertainties and challenges associated with implementing Sustainable Aviation Fuel (SAF) in Colombia, from which it determines the possible certified technologies under the ASTM D 7566 standard as well as co-processing technologies contemplated within the ASTM D 1655 standard, more suitable for the implementation of SAF production. Likewise, through the PESTEL tool (Political, Economic, Social, Technological, Environmental, and Legal), a diagnosis is made in order to obtain an updated overview of the implementation of SAF in Colombia. Based on the above, it provides recommendations to mitigate the uncertainties
identified, and it is complemented by the ECOCANVAS tool, which applies to businesses related to the circular economy, and also include the net production potential of SAF in Colombia, considering the production of feedstock, in agricultural residue of sugarcane, oil palm, corn, and coffee. This
study concludes with some policy recommendations that can make SAF implementation viable and allow responsible institutions to organize themselves for better strategic action and identify the fields of research and the need for investment in R + D + i to strengthen the supply chain.@en
