폐기물처리 비용을 고려한 국내 영농부산물자원화 방안의 경제성과 환경성 분석

Abstract

In Korea, open burning of agricultural residues is prevalent due to inadequate collection systems, which have caused environmental impacts such asGHGs and particulates. This illegal treatment of agricultural residues also results in economic loss, considering that agricultural residues can be utilizedas resources such as pellets and energy sources. To understand the effect of avoiding open burning, this study evaluated the economic, environmental,and social effects of two alternative management options for agricultural residues: incineration and pelletizing. The study estimates the potential amountand dry weight by region for 18 items, taking various factors into account. Regarding the economic aspect, pelletizing facilities in all regions in Koreacreate economic benefits. This study shows that most regions have an environmental advantage by pelletizing residues. However, incineration createsmore environmental benefits than pelletizing in metropolitan cities with relatively low density of residues. It is expected that the environmental,economic, and social findings of this study can be used to inform policies for bioenergy as the need for agricultural residue increases.
