조건부 가치측정법을 이용한 유기성 폐기물 에너지화 시설 확대의

As economic growth and development of the living standard causes increasing production of organic waste, the desireto take advantage of organic waste to produce energy is also increasing. Organic waste-to-energy can contribute toimproving energy independence through domestic energy security as well as improving the environment by reducingthe need for landfills. This paper attempts to quantitatively analyze the non-market benefits arising from the organicwaste-to-energy policy. To this end, we apply a contingent valuation (CV) that is most widely used to measure the nonmarketbenefits. As for the willingness to pay (WTP) elicitation method, we employed the one-and-one-half-boundeddichotomous choice (DC) model, which produces higher statistical efficiency than the single-bounded DC model andyields greater consistency than the double-bounded DC model. In the CV survey result of 1000 Korean households, atotal of 586 households (58.6%) revealed zero WTP. This implies that the use of the mixture model to deal with zeroWTP responses was a suitable approach in our study. The yearly mean WTP was computed as KRW 3598 for the nextten years per household, which is statistically significant at the 1% level. Expanding the value to the national populationgives us KRW 67.3 billion per year and this value demonstrates the non-market benefits of the organic waste-to-energypolicy. This quantitative information could be utilized as a significant reference in the implementation of the organicwaste-to-energy policy.
