原始语种摘要: Grease trap waste and sewage scum grease are underutilized, high-lipid waste streams that have the potential to be converted into biodiesel. This report presents results from a longitudinal study of the variability in waste grease composition, a demonstration of technical feasibility of production of biodiesel from these wastewater greases, and an evaluation of the environmental and cost tradeoffs using life cycle assessment and techno-economic analysis. The average lipid content of sewage scum grease is seasonally dependent; lipid content ranges between 15-40% in cooler months and 3-21% in warmer months. The lipid content of grease trap waste ranges between 1-25% with no apparent seasonal trend; however grease trap waste is easily partially-dewatered by gravity separation to a lipid...
