Abstract

This study was conducted to prepare an incentive system (proposal) for the activation of waste-to-energy. Weights for each type of energy use were prepared by conducting prior research and economic analysis. In addition, the waste-to-energy incentive (proposal) was calculated in consideration of energy efficiency for each type of energy use. As a result of economic analysis of 11 biogasification facilities, the B/C value was found to be very diverse, ranging from 0.16 to 1.69. In terms of benefits, imports of waste treatment import fees were very high at 68.4 to 99.3% of the total, and four facilities with a surplus (+) or higher in the management balance. In order to convert energy consumption into units of sales volume, 0.58 Nm3/KW for power generation, 0.17 Nm3/kg for steam, and 1.00 Nm3/Nm3 for external supply were calculated using the 'scale factor'. The 'weight factor' was calculated as 0.249 for power generation, 0.656 for steam, and 0.806 for external supply, respectively, by use type.

본 연구는 폐자원에너지 활성화를 위한 폐자원에너지 인센티브제도(안)을 마련하기 위하여 수행되었다. 선행연구와 경제성 분석을 통해 에너지이용 형태별 가중치를 마련하였고, 폐자원에너지 인센티브(안)은 에너지이용 형태별로 에너지효율을 감안하여 산정되었다. 바이오가스화 시설 11개소의 경제성 분석 결과, B/C 수치가 0.16 ~ 1.69로 매우 다양하게 나타났다. 편익에서는 폐기물처리 반입료 수입이 전체의 68.4 ~ 99.3 %로 매우 높게 나타났고, 경영수지가 흑자(+)가 되는 '1' 이상인 시설이 4개소로 나타났다. 에너지 이용량을 판매량 Nm3 단위로 환산하기 위해 '단위환산' 계수로 발전 0.58 Nm3/KW, 스팀 0.17 Nm3/kg, 중질가스 1.00 Nm3/Nm3으로 산정하였고, '가중치'는 이용 형태별 각각 발전 0.249, 스팀 0.656, 중질가스 0.806으로 산정하였다.
