Application of ammonia emissions in the waste sector: Focus on the waste and incinerators type

Abstract

In this study, the necessity of developing national NH3 emission factors for waste incineration facilities was identified by calculating the NH3 emission factor for each type of waste through actual measurement, confirming that it is a missing source, and calculating the amount of emission according to the application. The developed emission factor was 0.010 kgNH3/ton for municipal solid waste and 0.015 kgNH3/ton for industrial waste, which was higher than the domestic waste emission factor of 0.003 kgNH3/ton for EMEP/EEA. The sewage sludge incineration facility was 0.001 kgNH3/ton, which was slightly lower than that of the previous study, but it was within the 95% confidence interval, confirming the necessity of emission factors for each type of incineration. In addition, as a result of recalculating the current NH3 emission in the waste sector by using the NH3 emission factor for each type of waste calculated in this study, it can be confirmed that it is about 3.5 times higher than the existing ammonia emission, so the need to develop the NH3 emission factor by waste incineration. In addition, it was identified that there is a need to improve the NH3 inventory in the waste sector. As a result of the uncertainty analysis of the calculated emission factor, it was lower than the level suggested by EMEP/EEA, confirming the validity of the data.
