Glycerol residue, a by-product of glycerol refining from a palm kernel oil methyl ester plant, was characterized using standard test methods. The selected parameters were the contents of glycerol, ash, moisture and matter organic non-glycerol (MONG) and pH. It was found to contain, on average, 20.2% glycerol, 64.3% ash, 3.0% moisture, 12.4% MONG at pH 12.8. Fatty acids (6.6%) were isolated and comprised mainly C8:0 (30.3%), C10:0 (9.4%) and C12:0 (40.8%).
