Summary: The increasing consumption and emissions of jet fuel worldwide have created the necessity for sustainable aviation fuel (SAF) technologies. One option is to use waste or biomass-based feedstocks, which can significantly reduce greenhouse gas emissions compared to conventional jet fuel. This study evaluates the implications of key variables on the deployment of SAF at Chicago's O'Hare International Airport and finds that woody biomass-based Fischer-Tropsch technology has the lowest production costs and reduces GHG emissions by 86% compared to conventional jet fuel.

Summary: The Brazilian aviation sector aims to reduce greenhouse gas emissions by up to 37% by 2030 and 43% by 2050 using alternative fuels. Potential feedstocks for biojet fuel production in Brazil were evaluated, showing a significant amount of available land for feedstock cultivation but highlighting challenges in conversion technologies. A self-sustained integrated process focusing on sugarcane as the main feedstock was found to improve biojet fuel production performance and reduce the need for cultivated lands.

Summary: The aviation industry has promoted various approaches to reduce CO2 emissions, including improving aircraft technology and using sustainable low-carbon fuels. However, achieving carbon-neutral growth and a 50% reduction in net emissions by 2050 compared to 2005 levels will require a combination of imminent aircraft technologies with a higher introduction of Sustainable Aviation Fuel (SAF). Results show that these goals cannot be met solely by the current strategies, and carbon-neutral growth may only be possible by 2040 with the right combination of technologies and SAF introduction rates.

Summary: Sustainable aviation fuel can greatly reduce aviation's impact on the climate by intelligently allocating the limited fuel supply. By using different blending ratios and targeting specific flights, the overall climate benefit of the fuel can be multiplied by a factor of 9-15. In the short term, blending fuel at lower ratios and distributing it to more flights still results in significant reductions in contrail energy forcing and total energy forcing.

Summary: This study analyzes the sustainability of Carinata as a feedstock for renewable fuels, focusing on the supply chain perspective. It finds that a significant amount of land in the Southeastern United States is suitable for Carinata production, which can partially meet the demand for aviation fuel. The carbon intensity of Carinata-based sustainable aviation fuel is significantly lower than that of conventional aviation fuel, justifying the need for government subsidies.

Summary: The aviation industry needs to reduce its climate impact, and sustainable aviation fuels (SAF) are favored as an option by European policymakers. These fuels have significantly reduced carbon emissions compared to fossil fuels. A mandatory quota for the use of sustainable fuels is likely to be introduced in Europe starting from 2025. However, the introduction of a blending mandate faces challenges.

Summary: The aviation industry has been studying strategies for producing sustainable aviation fuels (SAF) for over a decade, with a focus on detailed techno-economic analyses (TEA) of six SAF production technologies. Triglyceride-based Hydroprocessed esters and fatty acids (HEFA) emerged as the most economically competitive option, while lignocellulose-based technologies showed lower fuel yields and higher costs due to the high oxygen content of initial feedstock. Efforts are needed to improve SAF yields from lignocellulosic materials in order to achieve cost targets. Proposed integrated biomass/natural gas hybridized concepts could potentially result in more cost-effective SAF production.

Summary: The research developed a fabrication process using acidic ethanol/water as a medium to achieve homogeneous dispersion of chitin nanofibrils (ChNFs) in a chitin propionate (CP) solution, forming ChNF-reinforced CP nanocomposites. The use of acidified ethanol/water mixture resulted in clear and stable formulations with transparent properties and moderate UV-blocking capability. The ChNF-reinforced CP nanocomposites showed improved tensile strength, modulus, and maximum degradation temperature, indicating substantial reinforcing effects of ChNFs.

Summary: This paper presents a probabilistic framework for quantitatively assessing the impact of wildfire risk on supply chain networks. The research demonstrates that while wildfire damages to supply nodes are insignificant, total supply chain costs still increase considerably due to high unmet demand penalty and detours. Additionally, the study highlights the vulnerability of network configuration under wildfire risk.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.

Summary: This paper studies the thermal stability and decomposition of cork materials with and without silica aerogel filler. The results show that the decomposition is inhibited and the pyrolysis is significantly reduced with the addition of silica aerogel. This finding suggests that silica aerogel-infused cork may be a promising raw material for biofuel production with reduced environmental pollution.
