Abstract: This paper presents a case study of air pollution reduction analysis for a medium-sized starch factory in Nakhon Ratchasima, Thailand. Pertinent data surveyed and gathered included the factory basic information, production processes, air pollutant emission inventory, and air pollution measurements. The U.S.EPA's AERMOD air quality model was used to estimate current pollutant levels at nearby receptors and possible pollutant reduction resulting from suggested clean technology options. The analysis yielded 3 groups of 12 options. They were: (1) improvement at the tapioca stockpile area, (2) improvement at the starch drying process, and (3) improvement of the hot-air generators. The estimation by AERMOD showed the 12 options can reduce ambient dust and SO2 concentration levels at the receptors up to 44 percent and 30 percent, respectively. Evaluation results indicated that installment of a bag filter system and heat-recovery economizers for all 3 hot-air generators were the factory's most appropriate options-with respect to technical, economical, and environmental evaluation-for reducing the air pollution impacts to its community.
