Scale Up Characterization of Fats, Oils, and Grease for Reuse as Biofuels

摘要

1.Byproduct of food preparation, cooking, and cleanup of dishes, pots and pans, utensils, moping of grease laden floors, etc. 2.Cause pipeline blockage, sewer overflow, property damage, and taking up space in landfills 3.Processed at Wastewater Treatment Plants (WWTP) as waste grease (WG). 1.Landfill 1.1Hauled away to landfill 2.Incarnation 2.1Burned for energy 3.Anaerobic Digestion 3.1Broken down by microorganisms to produce biogas 1.Waste cooking oil (WCO) is used to extract the lipid fraction of FOG's 2.Can produce yellow grease, a biodiesel feedstock, without the use of solvents "new" to the existing biodiesel production process. 3.Through standard esterification and transesterification process, the yellow grease can be turned into biodiesel. 1.FOGs have always been viewed as a waste product and there is not much data available about its characteristics. 2.Composition of FOGs can vary based on time of the year, i.g. weather, change in industry procedures, etc. 3.Composition of FOGs can vary by WWTP, i.g. size of plant, industries in the area, etc. 1.Water- Energy absorber 2.Lipids- Desired product 3.Solids - Repurposed for incineration or digestion 4.% Free Fatty Acid (%FFA) - Used as indicator of extraction 5.Metals - May cause complications further down the supply chain.
