Abstract—This study aims to investigate the properties of grease residue from grease trap waste water treatment and to determination the performance of candles from grease residues. Grease residue from grease trap wastewater treatment system at Canteen in Valaya Alongkorn Rajabhat University Under the Royal Patronage. Grease processing at the source such as houses and restaurants is unsuitable for common types of pollutants, which are relatively small. The average amount of grease residue from the grease trap was 200 grams / day. The average household was 2.6 kilograms per day. The results showed that the physical properties of stored grease for more than 2 weeks were gray, high viscosity and foul odor. For new grease, is yellow light, soft texture, and odorless. This study uses a new fat density of 1.002 g/mL, the moisture content 58.04%, and the heating value was 8148.63 kcal / kg. The physical properties of the candles are produced at an appropriate ratio of 3: 1 (paraffin: grease residue). In comparison with conventional candles, the candles last for 2 hours and 10 minutes, but the candles are 3: 1 for 2 hours and 8 minutes, and 15 minutes with smoke.

Index Terms—Grease residue, waste water treatment, candles production.
