“…Life-cycle assessment (LCA) is a standardized tool to evaluate the environmental impacts of a product or a process throughout its life cycle. − LCA has been widely used to quantify the environmental impacts, especially the carbon intensity (or say, life-cycle GHG emissions), of SAF ,,,,− compared to their fossil-based counterparts. For example, Bhatt et al quantified the life-cycle GHG emissions of SAF produced from waste and biomass feedstocks, namely using cooking oil, vegetable oil, fats, municipal solid waste, lignocellulosic and biomass, via three technologies, i.e., HEFA, FT, and ATJ .…”
