국내 SRF 사용시설의 배출가스 내 바이오매스 함량 분석방법 연구- 용해선별법과 탄소동위원소 질량분석법 비교

Carbon dioxide produced from biomass is biogenic. It is considered to be neutral carbon, and is therefore excluded from calculations of greenhouse gas emissions. In Korea, methods for calculating greenhouse gas emissions are categorized into Tiers 1 to 4, according to emission activities. Emissions measured by the methods in Tiers 1 to 3 are partially excluded from total CO2 emissions according to the proportion of biomass contained in the waste. The Tier 4 method measures CO2 emissions by measuring the amount and composition of the exhaust gas. However, this method does not consider the biomass content. In Tier 4, as in Tiers 1 to 3, it is necessary to partially exclude CO2 emissions from the greenhouse gas emissions in the flue gas according to the biomass ratio. In this study, the biomass content of SRF used in domestic facilities was analyzed using SDM. In addition, the biomass content of the exhaust gas from these facilities was analyzed using AMS. It was found that SRF contains 43.6% biomass on average. Furthermore, it was confirmed that the biomass content of the SRF used in facilities measured by SDM and the biomass content of the exhaust gases measured by AMS were similar.
