This thesis focuses on sustainable aviation fuel (SAF), exploring its development and its potential to replace conventional aviation fuel. The review highlights the importance of understanding the effectiveness of these processes to address the environmental challenges associated with conventional aviation fuel, which is a major source of carbon emissions and climate change. The International Civil Aviation Organization (ICAO) has been recognized for its efforts to combat climate change through initiatives such as CORSIA, promoting the use of SAF and carbon offset mechanisms. The review also highlights the importance of ASTM D7566 in setting standards for SAF production and quality, ensuring compatibility with existing aircraft and infrastructure. Ultimately, the study highlights SAF's role in reducing the aviation sector's carbon footprint and contributing to global environmental goals.
