In this study, we investigated air pollutants in the glass industry, and converted the fuel of the melting furnace used in the glass industry for the first time in Korea from B-C Oil to LNG. By investigating the saving effect and changes in air pollutants NOx, SOx, and Dust, the following conclusions could be drawn. Switching the melting furnace fuel (BC Oil → LNG) to minimize the environmental impact of the glass industry resulted in a 65 % reduction in SOx, an 18 % reduction in Dust, and a 43 % increase in NOx. However, when the temperature of the melting furnace stabilizes, it will decrease. In terms of cost, it was possible to reduce the basic charge by about 200 million/year by reducing NOx, SOx, and dust. It was possible to reduce the NaOH usage by more than 80 %, saving about 100 million won/year of drug costs. EP dust generated from the electrostatic precipitator was able to reduce waste treatment cost by KRW 40 million/year by reducing NaOH usage by 80 % and EP dust by 65 %. Greenhouse gas emissions were reduced by 28,000 [tCO2/year], reducing about 800 million won based on 30,000 won in emission credits. This is to suggest an improvement plan that can be an effective and sustainable response to the change of pollutants according to the change of fuel used and the reduction goal of the 「Special Act on Air Environment Improvement in Air Management Areas」 to be enforced in 2020.
