Analysis of External Cost of Detergent Powder Production (Case Study: Tolypers Inc. - the Largest Iranian Manufacturer in Detergent Powder Industry)

The aim of this study is to analyse the external cost of detergent production in Tolypers Company in 2011. This study used fuel analysis technique to analyse the external cost of air pollution resulting from combustion in production process of detergents. Results from analyses show that external cost resulting from mazut is 2.6 times more than that from natural gas. It was also found that CO2, SO2 and NOx gases account for 56.2, 15.1 and 28.7%, respectively, of the external cost resulting from detergent production in 2011. Other results indicate that the amount of external cost of detergent production resulting from air pollution is strongly sensitive to the type of consumed fuel. To be more precise, although mazut provided only 8.3% of the thermal energy required in a year, it accounted for 19.3% of the external cost of detergent production in 2011. Accordingly, provision of sustainable energy of natural gas for Tolypers, utilization of cleaner alternative fuels when necessary, optimal utilization of fossil fuels to allow full combustion can effectively reduce the external cost of these produces
