A PRELIMINARY ANALYSIS OF WASTE OIL AND GREASE FROM THE CAMPUS CHICK-FIL-A FOR USE AS BIOFUEL

Abstract

Waste oil and grease (O&G) from GGC Dining Operation’s Chick-fil-A restaurant was gravity separated and then chemically transformed from fatty acid into methyl ester (biodiesel) and glycerol, with the methyl ester subsequently extracted and dried from the product mixture. Characterization of the methyl ester (biodiesel) was accomplished using FT-IR, NMR, GC-MS, ICP-MS, thermodynamics via micro-bomb calorimetry, and density and viscosity measurements. Results indicate biodiesel methyl ester composition of approximately 54% methyl oleate [cis-9] and 33% methyl linoleate [cis-9,12], consistent with the Chick-fil-A’s use of peanut oil as the primary cooking oil. Characterization results will be presented along with direction of future work, to include suitability of waste O&G for use as a biofuel.
