Secondary Substances

In the case of sewage sludge, as direct landfilling was recently prohibited, it is treated through incineration. Among the air pollutants discharged through the incineration of sewage sludge, NOx and SOx are considered secondary substances of PM2.5 and are being managed accordingly. However, NH3, another of the secondary substances of PM2.5, is not well managed, and the amount of NH3 discharged from sewage sludge incineration facilities has not been calculated. Therefore, in this study, we sought to determine whether NH3 is discharged in the exhaust gas of a sewage sludge incineration facility, and, when discharged, the NH3 emission factor was calculated, and the necessity of the development of the emission factor was reviewed. As a result of the study, it was confirmed that the amount of NH3 discharged from the sewage sludge incineration facility was 0.04 to 4.47 ppm, and the emission factor was calculated as 0.002 kg NH3/ton. The NH3 emission factor was compared with the NH3 emission factor of municipal solid waste proposed by EMEP/EEA (European Monitoring and Evaluation Programme/European Environment Agency) because the NH3 emission factor of the sewage sludge incineration facility had not been previously determined. As a result of the comparison, the NH3 emission factor of EMEP/EEA was similar to that of municipal solid waste, confirming the necessity of developing the NH3 emission factor of the sewage sludge incineration facility. In addition, the evaluation of the uncertainty of the additionally calculated NH3 emission factor was conducted quantitatively and the uncertainty range was presented for reference. In the future, it is necessary to improve the reliability of the NH3 emission factor of sewage sludge incineration facilities by performing additional analysis with statistical representation. In addition, the development of NH3 emission factors for industrial waste incineration facilities should be undertaken.

NH3 is one of the major substances contributing to the secondary generation of PM2.5; therefore, management is required. In Korea, the management of NH3 is insufficient, and the emission factor used by EPA is the same as the one used when calculating emissions. In particular, waste incineration facilities do not currently calculate NH3 emissions. In the case of combustion facilities, the main ammonia emission source is the De-NOx facility, and, in the case of a power plant with a De-NOx facility, NH3 emission is calculated. Therefore, in the case of a Municipal Solid Waste (MSW) incinerator with the same facility installed, it is necessary to calculate NH3 emissions. In this study, the necessity of developing NH3 emission factors for an MSW incinerator and calculating emission was analyzed. In addition, elements to be considered when developing emission factors were analyzed. The study found that the NH3 emission factors for each MSW incinerator technology were calculated as Stoker 0.010 NH3 kg/ton and Fluidized Beds 0.004 NH3 kg/ton, which was greater than the NH3 emission factor 0.003 NH3 kg/ton for the MSW incinerator presented in EMEP/EEA (2016). As a result, it was able to identify the need for the development of NH3 emission factors in MSW incinerators in Korea. In addition, the statistical analysis of the difference between the incineration technology of MSW and the NH3 emission factor by the De-NOx facility showed a difference in terms of both incineration technology and De-NOx facilities, indicating that they should be considered together when developing the emission factor. In addition to MSW, it is believed that it will be necessary to review the development of emission factors for waste at workplaces and incineration facilities of sewage sludge.

This study aims to analyze whether ammonia emission occurs when municipal solid waste (MSW) is incinerated. In cases where ammonia is emitted, we aim to develop an emission factor, calculate annual emission amounts by utilizing activity data (waste incineration amount) applied in air pollutant emission calculations for the waste combustion in Korea, and investigate whether there is a need for emission calculation. As a result of the study, the ammonia emission factor of the MSW incineration facility to be studied was 0.0091 kgNH3/ton, which was 3 times higher than the emission factor in Europe. In the case of emissions, a randomly developed emission factor was applied to confirm the necessity of development of the emission factor, and as a result of the application, it was found to be 22 NH3 ton/year, which is the same number as the annual NH3 emission of the entire waste treatment sector in 2016. Therefore, we believe that MSW incinerator facilities should be recognized as one of the major NH3 omitted emission sources. Moreover, it is evident that there is a need for an NH3 emission factor and emission calculations that reflect the characteristics of Korea.

Seed germination trials have relevance in measuring soil toxicity. The current study was there-fore conducted to investigate the effect of municipal solid waste incineration fly ash (MSWIFA) and sewage sludge (SS) from the Phuket municipal waste incinerator and wastewater treatment plant as fertilizer substitutes on seed germination and growth parameters of sweet corn (Zea maysL.). A field experiment was conducted at the National Corn and Sorghum Research Station, Na-khon Ratchasima Province, using a randomized complete block design (RCBD). The treatmentsconditions were: 1) non-amended soil, 2) 378.125 kg MSWIFA ha-1, 3) 543.75 kg SSha-1,4) 756.25 kg MSWIFA ha-1, 5) 1087.5 kg SS ha-1, and 6) 378.125 kg MSWIFA ha-1 + 543.75 kg SS ha-1. The results indicated that application rates of MSWIFA and SS have profound effects on plant establishment and growth characteristics. The highest germination index (22.26), vigorindex (146.4), leaf number (5.65), and fresh and dry weight (5.78 and 2.35g plant-1), respect-tively) were recorded from seeds treated with SS (1087.5 kg ha-1), while the highest seed ger-mination was found in 378.125 kg MSWIFA ha-1 + 543.75 kg SS ha-1. The result suggested the alternative use of MSWIFA and SS without addition of fertilizer on agricultural soils.
