“…However, the SAF pathway presented in Huq et al could achieve much lower well-to-wake CI because of its significantly higher avoided BAU waste management credits (−154 g of CO 2 e/MJ) compared to those for Scenario 3 (−24 g of CO 2 e/MJ) in this study. These strikingly high avoided BAU credits for food-waste feedstocks are also observed in other reported SAF pathways and are inherent to the fuel pathways leveraging food waste as feedstock . BAU scenarios for food waste management typically assume landfill disposal, which involves a significant amount of uncollected methane emissions from anaerobic microbial activity in landfills.…”

“…These strikingly high avoided BAU credits for food-waste feedstocks are also observed in other reported SAF pathways and are inherent to the fuel pathways leveraging food waste as feedstock. 39 BAU scenarios for food waste management typically assume landfill disposal, which involves a significant amount of uncollected methane emissions from anaerobic microbial activity in landfills. Thus, when compared with foodwaste based SAF pathways, the SAF pathways presented in the current study seem to be more carbon-intensive despite their less carbon-intensive conversion processes.…”

To reduce emissions from combustion of fossil fuels, sustainable aviation fuels (SAFs) have the potential to decarbonize the aviation sector. Redirecting wastes from conventional waste management practices and using them as cost-effective feedstocks for low-carbon fuels can reduce emissions from both waste disposal and fuel combustion. One approach is to upgrade wet wastes to SAF precursors, such as volatile fatty acids (VFAs). In this study, novel membrane-assisted arrested methanogenesis was developed to convert high-strength wastewater to VFAs. Based on experimental results of VFA production, techno-economic and life-cycle analyses were conducted to estimate the potential economic and environmental benefits of SAF production from high-strength wastewater via VFAs. By evaluating three proposed scenarios for VFA production, a minimum production cost of VFA is achieved at $0.60/kg VFA at a wastewater flow rate of 1100 MT/d. For the corresponding VFA-derived SAF, the estimated minimum fuel selling price is $4.64/gasoline gallon equivalent. The life-cycle analysis shows that up to a 71% reduction in greenhouse gas emissions can be achieved relative to its fossil-counterpart along with lower water and fossil-fuel consumption.

Biomass is an attractive raw material for the production of fuel oil and chemical intermediates due to its abundant reserves, low price, easy biodegradability, and renewable use. Hydroxymethylfurfural (5‐HMF) is a valuable platform chemical derived from biomass that has gained significant research interest owing to its economic and environmental benefits. In this review, we examine recent advances in biomass catalytic conversion systems for 5‐HMF production, with a focus on the catalysts selection and feedstocks’ impact on the 5‐HMF selectivity and yield. Specifically, we evaluate the potential of zeolite‐based catalysts for efficient biomass catalysis, given their unique pore structure and tunable (Lewis and Brønsted) acidity. We summarize and assess the benefits of hierarchical modifications and the interactions between porosity and acidity in zeolites, which are critical factors for the development of green catalytic systems to convert biomass to 5‐HMF efficiently. Our review suggests that Zeolite‐based catalysts hold significant promise in facilitating the sustainable utilization of biomass resources.
