WERF selects Drexel for biodiesel from wastewater greases project
The Water Environment Research Foundation has selected Drexel University to perform research that will monitor and quantify the composition of waste greases to improve knowledge about the feasibility of grease-to-biodiesel processes. A key outcome of the Extraction of Lipids from Wastewater to Produce Biofuels (U3R13) project is an evaluation of the economic and environmental sustainability of converting waste greases to biofuels within a wastewater management system.
Fats, oils, and greases are separated from wastewater streams to prevent sewer overflows. At the source, food service establishments install grease interceptors to remove these materials called trap grease. An estimated two million metric tons are collected each year. Converting them to biofuels helps wastewater facilities reduce the amount of energy purchased from local utilities. Purchasing less energy outside the plant will increase sustainability of the plant.
This project will include longitudinal studies of variability in trap grease and scum grease compositions and quantities. The studies will guide an analysis of alternative process designs for separating components of these waste greases, converting some to biodiesel, and purifying the biodiesel.
The Water Environment Research Foundation, a nonprofit organization formed in 1989, is America's leading independent scientific research organization dedicated to wastewater and stormwater issues.

1Diesel fuel represents oil product which is the result of oil distillation. Mixing of the distillate and straight fractions in certain proportions (compounding) defines certain brand of diesel fuel. Usually mix is made from direct diesel fuel and primary distillation and the light gasoil received by catalytic cracking. In compliance standards, at distillation of oil three brands of diesel fuel can turn out: (summer diesel fuel) – for temperature above 0 °C; З (winter diesel fuel) for temperature to-20-30 °C; And (Arctic) for the lowest temperatures, to -50 °C. Each type of diesel fuel assumes the rated content of sulfur and sulfuric combinations, and also a certain temperature of freezing. The kind of fuel can be reached also by mixing of basic fuel with additives using diesel mixing systems.
