Abstract
Thermal recovery of used cooking oil yielded in a university campus was examined. The used oil was directly combusted for generating hot water. Because the oil obtained contains much amount of solid impurities and water, ultra sonic treatment was carried out for preparing fuel from the waste. Simple assessment on the CO2 emission resulted in the reduced emission, which could be emphasized by longer utilization. The limited oil amount yielded and also the discontinuous thermal demand in the university campus were the important factors for completing the utilizing system.
